Today, we announce dav2d, a fast decoder for the new AV2 codec, developed by members of the VideoLAN community. A few weeks ago, we opened the repository and started development in public. Since then, AV2 itself has reached its first official specification release, making this a good moment to explain what dav2d is, why we started it, and where the project stands today. https://jbkempf.com/interviews/lex-fridman-496-ffmpeg/ Tue, 05 May 2026 00:00:00 +0000 https://jbkempf.com/interviews/lex-fridman-496-ffmpeg/ 3-hour conversation with Lex Fridman and Kieran Kunhya on FFmpeg, VLC, codecs, and the global open-source video stack. https://jbkempf.com/interviews/fosdem-2026-vlc-ffmpeg-kyber/ Sun, 01 Feb 2026 00:00:00 +0000 https://jbkempf.com/interviews/fosdem-2026-vlc-ffmpeg-kyber/ Annual FOSDEM update on the state of FFmpeg, VLC, x264, dav1d, libplacebo, libspatialaudio communities — plus the latest from Kyber. https://jbkempf.com/blog/2025/libspatialaudio-0.4/ Sun, 21 Dec 2025 00:00:00 +0000 https://jbkempf.com/blog/2025/libspatialaudio-0.4/ libspatialaudio 0.4.0 is a major release of VideoLAN’s spatial audio renderer, covering HOA, object rendering, ADM-style concepts and IAMF-oriented workflows, with real-time-friendly binaural and loudspeaker outputs. https://jbkempf.com/blog/2025/DVD_audio_edition/ Mon, 24 Nov 2025 00:00:00 +0000 https://jbkempf.com/blog/2025/DVD_audio_edition/ libdvdread 7, libdvdnav 7 and libdvdcss 1.5 bring full DVD-Audio parsing, navigation and CPXM decryption, along with build-system modernization and improved platform stability. https://jbkempf.com/blog/2025/dav1d-1.5/ Sun, 16 Nov 2025 00:00:00 +0000 https://jbkempf.com/blog/2025/dav1d-1.5/ dav1d 1.5 Sonic brings improvements across all major architectures, major stack and code size reductions, and completes the core optimization work of the AV1 decoder. https://jbkempf.com/blog/2025/European_SFS_Award_2025/ Mon, 10 Nov 2025 00:00:00 +0000 https://jbkempf.com/blog/2025/European_SFS_Award_2025/ Jean-Baptiste Kempf reflects on receiving the European SFS Award 2025 at SFSCON in Bolzano, celebrating the collective success of the VideoLAN and VLC communities. https://jbkempf.com/blog/2025/libbluray-1.4.0/ Sun, 24 Aug 2025 13:11:09 +0000 https://jbkempf.com/blog/2025/libbluray-1.4.0/ Update on the Bluray open source stack: libbluray 1.4.0 and libudfread 1.2.0 It has been more than ten years since I last wrote about the Blu-ray libraries (So I bought a Blu-ray drive…, Disc libraries releases, Blu-Ray libraries update, Blu-Ray libraries releases), but the projects themselves have continued evolving with regular releases. These days, with the growing limitations of the major streaming platforms, playback of actual physical discs is key for the preservation of media. https://jbkempf.com/blog/2025/mirrorbits-0.6/ Mon, 21 Apr 2025 15:18:09 +0000 https://jbkempf.com/blog/2025/mirrorbits-0.6/ Mirrorbits 0.6: A new Hope Since the middle of last year, I have taken over the maintainership of Mirrorbits, the open-source Geo-basedredirector, that we use to distribute the binaries of VLC, and that is now used by numerous open source projects and Linux distributions.

It has a full native VVC decoder, a new MV-HEVC decoder, a new LC-EVC decoder, a new xHE-AAC decoder, it finishes the IAMF decoder and it also adds Vulkan hardware encoding, VVC encoding, ARM64 and RISC-V optimizations and other hardware accelerations. Knowing that FFmpeg 7.1 is a LTS release, this is a major feat, in addition to the already very strong FFmpeg 7. https://jbkempf.com/blog/2024/ffmpeg-7.0.0/ Mon, 15 Apr 2024 10:22:07 +0000 https://jbkempf.com/blog/2024/ffmpeg-7.0.0/ FFmpeg 7.0 FFmpeg 7.0 was released a few days ago: a major release with numerous new features and a new major version of the APIs. It features a multi-threaded CLI, a first version of our native VVC decoder, support for EVC decoding and encoding, numerous RISC-V & loongarch optimizations and D3D12 hardware decoding. Multi-threading FFmpeg The CLI of FFmpeg is used everywhere and can do so many things. But it’s an ancient codebase, and has many limitations, notably when doing multiple decodes, encodes or filters. https://jbkempf.com/blog/2023/dav1d-1.2.0/ Wed, 03 May 2023 14:28:07 +0000 https://jbkempf.com/blog/2023/dav1d-1.2.0/ dav1d 1.2.0 If you’ve followed a bit my blogposts, or Phoronix, in the last few years, you should have seen that we’ve focused on SIMD optimizations for all the platforms supported. dav1d 1.2.0 is no different. History of optimizations in dav1d At the beginning, we focused on normal 8-bit assembly, until we reached release 0.7.1 where we started doing a lot of work on high-bitdepth. The major part of that work was finished with 0. https://jbkempf.com/blog/2022/FFmpeg-5.0/ Mon, 17 Jan 2022 12:42:22 +0000 https://jbkempf.com/blog/2022/FFmpeg-5.0/ FFmpeg 5.0 release Today, FFmpeg made a new release, numbered 5.0, called Lorentz. This release is a major release, with numerous API changes, a few new features, and because we hope to have this one as LTS. Big API changes and deprecations FFmpeg has had a lot of API changes during its history, but the project is very careful about those deprecations and removals: we deprecate then we wait to allow the users time to upgrade, then we remove the APIs, because it could break the users programs. https://jbkempf.com/blog/2021/dav1d-0.9.1-a-ton-of-asm/ Sun, 01 Aug 2021 14:31:23 +0000 https://jbkempf.com/blog/2021/dav1d-0.9.1-a-ton-of-asm/ dav1d 0.9.0 optimizations about 10bit Since 0.7.1 release from last year, we’ve focused on optimizing high-bitdepth decoding, on ARM and x86 platforms. For those who don’t know, high-bitdepth means 10bit and 12bit per pixels instead of 8, which increases the precision of colors and is necessary for UHD and HDR images and videos. (Note: 12bit is very rarely used in consumer cases.) Because the data uses 10bit per component, we need to write specific assembly code, different from the 8bit code. https://jbkempf.com/interviews/la-folle-histoire-de-vlc/ Tue, 22 Jun 2021 09:46:44 +0200 https://jbkempf.com/interviews/la-folle-histoire-de-vlc/ After spending a lot of time on ARM64 during 0.5.0 and 0.7.0, we’re spending some times for the people who are stuck with older phones, still running on 32-bit platforms. With these new optimizations, we’re 28% faster than before when decoding the Chimera sample on a Snapdragon 835. The result is that we’re only 20%-25% slower in 32bit compared to 64bit, which is quite a feast.

This release brings ChromeCast integration to iOS and UWP, like it was present on desktop and Android versions. ChromeCast and hardware encoding However, it supports ChromeCast in a more performant way, because we added hardware encoders to those 2 platforms. Indeed, here, for local streaming, we care more about speed and battery saving than we care about bandwidth efficiency, si hardware encoding is a good fit. https://jbkempf.com/blog/Welcome-back/ Wed, 18 Jul 2018 21:21:54 +0000 https://jbkempf.com/blog/Welcome-back/ After quite a bit of time far from the blog, I am back around here. The biggest reason for this silence was that this was taking a lot of my time, but I had almost no positive feedback on those posts. Let’s see if we can do better this time :) Here is a small cone, to make you more happy: https://jbkempf.com/blog/Last-week-in-VideoLAN-53/ Wed, 24 Aug 2016 09:10:52 +0000 https://jbkempf.com/blog/Last-week-in-VideoLAN-53/ 53rd VideoLAN report During the core of the hot European summer, here is a weekly report about the last 2 weeks in the VLC and VideoLAN communities! It was a bit calm, to be honest; and I’m a bit late to publish. Summer is the cause :) Features VLC The week started by a lot of code cleanup and renaming for the Mac OS interface. We also had improvements focus on the Sierra release. https://jbkempf.com/blog/Last-week-in-VideoLAN-52/ Mon, 08 Aug 2016 15:23:05 +0000 https://jbkempf.com/blog/Last-week-in-VideoLAN-52/ 52nd VideoLAN report Another summer week passes by and here is a new weekly report about the VLC and VideoLAN communities! Features VLC The week started with numerous additions to the Direct3D video accelerations and video outputs, to continue the support for 10bits decoding and HDR. Related to those improvements, we added support for hardware decoding of HEVC decoding inside the TS format, by improving our HEVC packetizer. We fixed (actually added) the support of QuickTime Videos inside MKV, aka MP4-inside-MKV; and also the support for QuickTime Audio inside MKV. https://jbkempf.com/blog/Last-week-in-VideoLAN-51/ Wed, 03 Aug 2016 11:37:20 +0000 https://jbkempf.com/blog/Last-week-in-VideoLAN-51/ 51st VideoLAN report So, after a few crazy weeks, I’m coming back to a more regular schedule for my weekly reports about VLC and VideoLAN. Features VLC Decoder fallback The major change, during last week, was the possibility to restart the audio decoders when the audio device changes. This is very useful when you switch from normal decoders to SPDIF/HDMI pass-through for DTS, Dolby and related codecs. In the past, VLC could only restart the filters, not the decoders, so our Dolby and DTS decoders were actually filters. https://jbkempf.com/blog/This-week-in-VideoLAN-50/ Mon, 25 Jul 2016 14:25:56 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-50/ 50th VideoLAN report So, after a few crazy weeks, I was taken a bit by RealLife©®, and we’ve had 3 weeks without report. And this one is late. :) Therefore, here is a new report about the VLC and VideoLAN communities, covering the last 3 weeks! The report will be a bit more summarized that usual, and more dense in information, for obvious reasons. :) Features VLC We’ve added support for codecs with colors in 12bit-depth, in YUV 4:2:0, 4:2:2 and 4:4:4. https://jbkempf.com/blog/Announcing-VLC-for-UWP-2.0/ Tue, 28 Jun 2016 12:54:50 +0000 https://jbkempf.com/blog/Announcing-VLC-for-UWP-2.0/ VLC for Windows 10 beta If you follow this blog, after a long development period (and a lot of issues), VideoLAN is finally releasing the beta of VLC for Windows 10, numbered 2.0.0. This beta is the first version targeting Windows 10 and running on the Universal Windows Platform, aka UWP. Features The Windows 10 application has all the features available on iOS and Android and a few more. Like the classic VLC, it supports a very large number of formats, but it also has a medialibrary triaging audio and video media, a full player with subtitles, audio/video synchronisation, an audio mini-player and a network shares browser! https://jbkempf.com/blog/This-week-in-VideoLAN-49/ Mon, 27 Jun 2016 20:49:46 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-49/ 49th VideoLAN report So, after two busy weeks, you can get a new weekly report about the VLC and VideoLAN communities! Releases Android 10 days ago, we released VLC for Android 2.0. After a long period of development, we’re finally at a release that supports more features than the old 0.9.x versions and the 1.7.x versions. UWP And last week, we released the new VLC for Windows 10, numbered 2.0 too. https://jbkempf.com/blog/This-week-in-VideoLAN-48/ Mon, 20 Jun 2016 07:40:34 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-48/ 48th VideoLAN report Another week passes by and here is a new weekly report about the VLC and VideoLAN communities! Features VLC Like our previous week, most of the work was focused on stabilizing features and bug fixing. Therefore, the changelog will be quite short too. :D A new type of module was introduced, named demux filter; they are used to filter or intercept demuxer controls commands and demuxing. The first use case of this type of module is the ChromeCast demux filter, to show the correct playback time when using the ChromeCast, that we merged this week too. https://jbkempf.com/blog/This-week-in-VideoLAN-47/ Mon, 13 Jun 2016 08:58:53 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-47/ 47th VideoLAN report A new week, a new weekly report about the VLC and VideoLAN communities! Features VLC After an intense previous week, most of the work was focused on stabilizing features and bug fixing. Therefore, the changelog will be quite short. :D In the core, we pushed multiple fixes for preparsing and input slaves and we added tests for those features. We also fixed issues in the media discoverer code. https://jbkempf.com/blog/VLC-for-Android-2.0/ Thu, 09 Jun 2016 15:02:01 +0000 https://jbkempf.com/blog/VLC-for-Android-2.0/ VLC for Android 2.0 After a long development period, VideoLAN is finally releasing VLC for Android 2.0. Our last major release was 1.7.0, more than 6 months ago! VLC for Android 2.0 is a major update to VLC for Android, that adds numerous features, notably: support for new releases of Android, network shares browsing and playback, video playlists, subtitles downloader, pop-up video view and support for multiwindows, an optional history panel, favorite network shares and URLs, and a merge between the Android TV and Android packages. https://jbkempf.com/blog/This-week-in-VideoLAN-46/ Tue, 07 Jun 2016 21:41:23 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-46/ 46th VideoLAN report A new week, a new weekly report about the VLC and VideoLAN communities! Vienna Meeting This week-end was the Q2 meeting of the VideoLAN asso, hosted in Vienna, by PSPDFKit. We gathered to fix pending issues for VLC 3.0, and we worked on the mobile apps and the VideoLAN server infrastructure. It was a great week-end! Features VLC During the week-end, we released VLC 2.2.4, to fix 2 security issues, one in VLC, one in a 3rd party library! https://jbkempf.com/blog/This-week-in-VideoLAN-45/ Sun, 29 May 2016 16:41:47 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-45/ 45th VideoLAN report After a couple of very busy weeks, we’re back on a normal schedule. Therefore, here is the weekly report about the VLC and VideoLAN communities! Features VLC We started the week by adding the support for MPEG-2 and VC-1 hardware decoders on Android in the mediacodec module. We also fixed some MPEG-4 regressions on this module. Hugo fixed a few issues on the UPnP module, and mostly added the support for Windows Media Sharing servers, in this module. https://jbkempf.com/blog/This-week-in-VideoLAN-44/ Mon, 23 May 2016 07:53:36 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-44/ 44th VideoLAN weekly report Once again, unfortunately, the report skipped a week :( But this report, the 44th report, is quite important for 2 reasons: it’s been over one year I’ve started those reports, since the first one was published on May 10th, last year; and this post is the 300th blogpost on this very blog! This also mean I skipped 8 weekly reports, and did dual-reports for those weeks, which is not too bad, compared to what I hoped to achieve… https://jbkempf.com/blog/This-week-in-VideoLAN-43/ Mon, 09 May 2016 20:59:51 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-43/ 43rd VideoLAN weekly reports After my 42nd report last week, and some nice encouragements, here is another weekly report about VideoLAN and VLC development. I was far from a computer last week, so here are 2 weeks in one. Features VLC Renderers The previous week, we started to introduce the concept of renderers in VLC. Those are distant devices displaying audio and/or video, instead of playing it locally. The usual device people know are ChromeCasts, UPnP/DLNA renderers, AirPlay, WiDi or DIAL devices. https://jbkempf.com/blog/This-week-in-VideoLAN-42/ Sun, 24 Apr 2016 21:01:32 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-42/ 42nd week of VideoLAN reports After a very busy week last week, here is another weekly report about VideoLAN and VLC development. 42 I’m surprised we’re already at 42 and I haven’t stopped doing it! Sometimes, I’m not sure it’s really useful, since I don’t see many comments… But lately, some people who don’t comment on this blog told me, in real life, that I should continue, so here is a new report. https://jbkempf.com/blog/This-week-in-VideoLAN-41/ Tue, 19 Apr 2016 09:32:02 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-41/ 41st week of VideoLAN reports Another week, another weekly report about VideoLAN and VLC development. Features VLC We started the week with fixes to build libVLC for WinRT. Then, after the work from last week, the DVB scanning was improved again, notably to manage timeouts; and the DTV module was fixed accordingly. The input core was also simplified, removing muteces, reducing the number of functions to create an input, and fixing some preparsing issues (and adding the related tests). https://jbkempf.com/blog/This-week-in-VideoLAN-40/ Mon, 11 Apr 2016 22:59:13 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-40/ 40th report about VideoLAN reports It’s been a few weeks without reports. I’m sorry, I was traveling a bit across the Ocean, and life caught up with me, a bit too much… And of course, the VideoLAN community has been busy during that time, so a lot happened, and catching up is even harder. So, this report is probably more summarized than usual, please excuse me for that. Features VLC The weeks started by fixing the Windows green lines regressions for 2. https://jbkempf.com/blog/This-week-in-VideoLAN-39/ Sun, 20 Mar 2016 16:09:19 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-39/ 39th week of VideoLAN reports Another week, another weekly report about VideoLAN and VLC development. Yes, even in the winter and the cold, things are happening! Features VLC The week started with more work on the Matroska (MKV) module, after the various refactoring of the previous weeks. We fixed some regressions, improved the parsing speed, but mostly fixed and improved chapters, ordered segments and edition handling. We also had fixes for Matroska scripts commands and a lot of this work should prepare the module for seeking improvements. https://jbkempf.com/blog/This-week-in-VideoLAN-38/ Mon, 07 Mar 2016 00:14:02 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-38/ 38th week of VideoLAN reports Another double-week report about VideoLAN and VLC development. Features VLC After the major work of the previous weeks on the topic, the week started with quite a few fixes on credentials and dialogs. We then repaired the Avahi service discovery (that has been broken for years), so that it can discover SMB, FTP, SFTP and NFS shares on Linux. The Qt playlist now allows to sort by disc number, and the search field is accessible with Ctrl+K shortcut. https://jbkempf.com/blog/This-week-in-VideoLAN-37/ Sun, 28 Feb 2016 19:45:25 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-37/ 37th week of VideoLAN reports Another week, another weekly report about VideoLAN and VLC development. Yes, I’m still here, and code is still happening :) Features VLC The week started by numerous patches cleaning the codebase. This is a trend we’ve seen a lot in VLC lately, and is a great sign. Thomas removed a few weird JNI interdependencies between modules, libVLC and libVLCjni for Android. The modules do not depend anymore on code in the libVLCjni library. https://jbkempf.com/blog/This-week-in-VideoLAN-36/ Sun, 21 Feb 2016 17:15:18 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-36/ 36th VideoLAN report And back to a normal schedule, this post is a weekly report about what happened in the VLC and VideoLAN communities, this week. Features VLC This week was a calm week on VLC, for once. We now receive the UPnP server icon, in the service discovery, and it should be also available through libVLC. On the TS demuxer side, we now do full sections assembling which will allow to do CRC32 checks. https://jbkempf.com/blog/These-weeks-in-VideoLAN-35/ Sun, 14 Feb 2016 21:08:30 +0000 https://jbkempf.com/blog/These-weeks-in-VideoLAN-35/ 35th VideoLAN report After the celebration of the 15th anniversary of VLC and the release of VLC 2.2.2, here are we back to normal weeks and here is a new report, on time. Once again, this post is a double-week report about the VLC and VideoLAN communities; and they were very very busy. Features and changes VLC Core, input The first thing that happened after FOSDEM, was that the HTTP support for gzip and deflate was removed and split into a new module named inflate. https://jbkempf.com/blog/15-years-of-VLC/ Mon, 01 Feb 2016 16:25:01 +0000 https://jbkempf.com/blog/15-years-of-VLC/ 15 years! Today marks the 15th anniversary of VLC! GPL Technically, today is the 15th anniversary of the relicensing of all the VideoLAN software to the GPL license, as agreed by the École Centrale Paris, on February 1st, 2001. If you’ve been to one of my talks, (if you haven’t, you should come to one), you know that the project that became VideoLAN and VLC, is almost 5 years older than that, and was called Network 2000. https://jbkempf.com/blog/This-week-in-VideoLAN-34/ Tue, 19 Jan 2016 21:17:46 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-34/ 34th VideoLAN report I was traveling quite a bit lately, so here is a double-week report about the VLC and VideoLAN communities. FOSDEM Once again, the VideoLAN team was present at FOSDEM. Here is a the usual Delirium Cafe photo! And of course, my talk about VLC 3.0. Features VLC The first change was related to ChromeCast: a new module was added, to split the control of the chromecast from the streaming part. https://jbkempf.com/blog/This-week-in-VideoLAN-33/ Tue, 19 Jan 2016 20:46:14 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-33/ 33rd VideoLAN report This is my second report in 2016 about what happened last week in the VLC and VideoLAN communities. VLC on AppleTV Of course, the big news of the week was the release of VLC for the AppleTV. Apple TV is the latest platform to which we added VLC support, to continue the VLC everywhere route, after VLC on ChromeOS, VLC for Android TV and VLC for Windows Phone that we added last year. https://jbkempf.com/blog/This-week-in-VideoLAN-32/ Sun, 10 Jan 2016 22:31:18 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-32/ 32nd VideoLAN report Another year, and another week working on VLC and VideoLAN. Happy New Year 2016! Features and changes VLC Another week started with improvements on the new HTTP/2 stack. We mostly got support for HTTPS through HTTP proxy and HTTP tunnel (RFC7639) but also a better documentation and better cookies handling. The large work of the week was the merge of the new Keystore API for the VLC core. https://jbkempf.com/blog/This-week-in-VideoLAN-31/ Mon, 28 Dec 2015 15:18:14 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-31/ 31st VideoLAN report After the holiday season, this is the last of the weekly reports for 2015 for VideoLAN and VLC development! Technically, we’re already in 2016, but this report will cover the last 2 weeks of 2015 and only a few days of 2016. :) Features and changes VLC As one can expect if one has read my previous reports, we had quite a few improvements on the HTTP/2 pipeline (multiple cookies, test cases, …) and on the HEVC/H. https://jbkempf.com/blog/libdvdcss-1.4.0-release/ Thu, 24 Dec 2015 11:13:27 +0000 https://jbkempf.com/blog/libdvdcss-1.4.0-release/ libdvdcss 1.4.0 For once, just a very short blogpost, to announce that libdvdcss 1.4.0 is out! This release is a major release of libdvdcss, released a bit more than one year after 1.3.0. It’s focused on stability, cleaning, deprecating and small improvements. In terms of commits, this is also a very large release, with more than 150 commits (on a total of 486 since libdvdcss creation). Features The biggest feature of 1. https://jbkempf.com/blog/This-week-in-VideoLAN-30/ Mon, 21 Dec 2015 00:54:49 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-30/ 30th week of VideoLAN reports And, closing to holidays season, another week goes by, another weekly report about VideoLAN and VLC development you get! Features and changes VLC/ChromeOS release If you’ve missed it, this week, we released the first version of VLC for ChromeOS under the GPLv3 license. This is a port of the Android application to the Android Runtime on Chrome. It shares most of the code with the Android version, but includes a few ChromeOS specific modifications. https://jbkempf.com/blog/Announcing-VLC-for-Chrome-OS/ Wed, 16 Dec 2015 17:37:13 +0000 https://jbkempf.com/blog/Announcing-VLC-for-Chrome-OS/ VLC on ChromeOS ChromeOS is one of the last Operating Systems where you could not run VLC and play all your media as you wished. :) Even worse, it was the only significant Desktop Operating Systems that we did not support (so far, VLC exists for Windows, OS X, Linux, BSD, Solaris, OS/2, Haiku/BeOS, ReactOS). At the same time, VLC for Android is quite popular and is supported on most phones and tablets, and is currently being expanded to Android TVs or other forms of Android. https://jbkempf.com/blog/Last-week-in-VideoLAN-29/ Tue, 08 Dec 2015 10:12:34 +0000 https://jbkempf.com/blog/Last-week-in-VideoLAN-29/ 29th VideoLAN report This report is a bit special, since the previous week-end was the VideoLAN meeting in Barcelona, so I did not do a post last week. So, I’ll cover in this post, the work of the last 2 weeks on VideoLAN and VLC development. VideoLAN meeting The VideoLAN team met for our 4th quarter meeting, in Barcelona, Spain, in the offices of Skyscanner. We were around 20 for 2 days, and worked on quite a few things around VLC. https://jbkempf.com/blog/This-week-in-VideoLAN-28/ Mon, 30 Nov 2015 09:09:22 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-28/ 28th week of VideoLAN reports Another week, another weekly report about VideoLAN and VLC development. I’m still here. :) Features and changes VLC Following last week’s work on Freetype font fallback on OS X and iOS, after a few fixes, we removed the QuartzText and the WinGDI text renderers. The Freetype renderer should always be the best one, now. We’ve added a new libVLC event: libvlc_MediaPlayerChapterChanged to detect a change of chapters and we’ve fixed the libvlc_MediaPlayerTitleChanged event, that was not fired in all cases. https://jbkempf.com/blog/This-week-in-VideoLAN-27/ Mon, 23 Nov 2015 08:45:31 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-27/ 27th week of VideoLAN reports And we’re back to normal, so here is the (now usual) report detailing the work in the VideoLAN community, from last week. Paris Open Source Summit The VideoLAN team was at the Paris Open Source Summit, in the association village. Our stand was featuring the Android TV version decoding 4K playback on a Sony TV, a few tablets running various versions of VLC, the Nexus player with VLC playing DVDs on Android TV. https://jbkempf.com/blog/This-week-in-VideoLAN-26/ Mon, 16 Nov 2015 22:46:55 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-26/ 26th week of VideoLAN reports This week-end, I really did not feel like writing anything about last week, because… you know… fuck it. … … … But then, I realized that I shouldn’t stop living because some assholes believe the way I live is the wrong one. So after crying a bit, here is the short (and late) report about last week in the VideoLAN community. Features and changes VLC Once again, a week started with fixes about our adaptive streaming support ( :) ), notably the Smooth Streaming part, to support the Language attribute and per-stream Timescale. https://jbkempf.com/blog/This-week-in-VideoLAN-25/ Sun, 08 Nov 2015 23:43:03 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-25/ 25th week of VideoLAN reports Here is a new report detailing the work that happened during the last week in the VideoLAN community. The last weeks have been crazy busy in VLC development, so this week was finally calmer, because we’ve focused on bug fixing and testing. :) Features and changes VLC The week started with the removal of the old Smooth Streaming input, deprecated by the new demux code added last week. https://jbkempf.com/blog/This-week-in-VideoLAN-24/ Mon, 02 Nov 2015 09:35:15 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-24/ 24th week of VideoLAN reports The last few weeks were extremely busy, so here is the latest weekly report about VLC development, hoping it won’t be too disappointing. :) Features and changes VLC Qt The week started with a workaround of a very problematic Qt5.5 regression. Qt5.5 is breaking 2 important behaviors of VLC: video and hotkeys. One is a Qt regression that was introduced in Qt5.5 and one was probably an issue in VLC, but could also be an issue in the X server. https://jbkempf.com/blog/This-week-in-VideoLAN-23/ Sun, 25 Oct 2015 22:21:00 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-23/ 23rd week of VideoLAN reports Yet another week, another new weekly report about the VideoLAN community and the VLC development community. Features and changes VLC Protocol Redirections We’ve added support for inter-module redirections. In the past, the HTTP or FTP redirections were only done in the same module. That caused limitations, if we wanted for example to redirect to a different protocol, like HTTP-> FTP or HTTP -> HTTP2. Now, a redirection will spawn a new module, that can support a different protocol. https://jbkempf.com/blog/This-week-in-VideoLAN-22/ Mon, 19 Oct 2015 12:17:37 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-22/ 22nd week of VideoLAN reports A new week, a new weekly report about the VideoLAN community and where the VLC development is going. Compared to the very busy previous week, this one might look a bit calm. :D Features and changes VLC The week started with fixes in quite a few modules: the new SAPI module, HLS, videotoolbox, TTML, MMAL raspberryPi decoder, OS X interface and several encoders. As prepared during the previous week, the new SSA renderer for OS X and iOS was plugged. https://jbkempf.com/blog/This-week-in-VideoLAN-21/ Mon, 12 Oct 2015 09:14:36 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-21/ 21st week of VideoLAN reports For the 21st time, here is the weekly report of what has happened in the VideoLAN community and VLC development, during the past week. Features and changes VLC Last week started again with Felix committing, this time to port the CAOpenGLLayer to OS X. The iOS AudioUnit output gain support for a correct mute implementation, and was moved to a modern Objective-C syntax. The core gained stream_CustomNew(), to create custom streams; it also gained demux_New() and those 2 functions will be used for adaptive streaming, that need slave streams and demux. https://jbkempf.com/blog/This-week-in-VideoLAN-20/ Mon, 05 Oct 2015 22:50:40 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-20/ 20th week of VideoLAN reports For the 20th time, here is the weekly report of what has happened in the VideoLAN community and VLC development, during the past week. I’m surprised to have been keeping at it for already 5 months. It’s a bit boring to do, and also a bit lonely, but I believe it is necessary so that everyone knows what’s going on. Features and changes libVLC For once, we’ll start with libVLC, and the new libVLC backend for EFL/Emotion. https://jbkempf.com/blog/libbluray-0.9.0/ Sun, 04 Oct 2015 15:17:13 +0000 https://jbkempf.com/blog/libbluray-0.9.0/ Almost 6 months after libbluray 0.8.0, I’m delighted to announce libbluray 0.9.0! We published, in the meantime, a version 0.8.1, that was focused on fixing the biggest regressions of 0.8.0. Between 0.8.0 and 0.9.0, we had around 100 commits. libbluray 0.9.0 introduces a few cool features: new API to access files from the VFS: bd_get_meta_file() and bd_read_file(), this is useful for embedded subtitles, better support for usage in C++ projects largely improved support of the BD-J menus and features fixed Xlet font-caching (with security checking) caching of BD-J bdjo objects numerous fixes for crashes and small issues Have fun testing it! https://jbkempf.com/blog/Last-weeks-in-VideoLAN-19/ Mon, 28 Sep 2015 16:37:36 +0000 https://jbkempf.com/blog/Last-weeks-in-VideoLAN-19/ 19th week of VideoLAN reports Because of the VideoLAN Dev Days that happened last week-end, here is a dual-week report of what has happened in the VideoLAN community and VLC development, during the past 2 weeks. :D It explains also why there may not be as many commits as we usual have. This report is also shorter because I don’t have enough time to detail as much as I’d like. https://jbkempf.com/blog/Emotion-backend/ Sat, 26 Sep 2015 17:25:04 +0000 https://jbkempf.com/blog/Emotion-backend/ This is quite short a post about libVLC in EFL (Enlightenment). Emotion is the multimedia API of the Enlightenment Foundation Libraries (EFL) used in the e17 desktop environment. It is similar to KDE’s phonon. For a long time, the libVLC backend for Emotion was not a full backend, but was considered as a generic player, mainly because of the license, at the time. The 2 full backends in EFL were based on GStreamer and Xine. https://jbkempf.com/blog/The-future-of-codecs-is-at-VideoLAN-Dev-Days-15/ Wed, 16 Sep 2015 13:56:50 +0000 https://jbkempf.com/blog/The-future-of-codecs-is-at-VideoLAN-Dev-Days-15/ VideoLAN Dev Days 15 Like the last few years, we are organizing the VideoLAN Dev Days, this week-end, in Paris. The conference is nicely hosted by the French unicorn Criteo and sponsored by Google and Videolabs. Last year was in Dublin: New Codecs conferences This year, we’ll have quite a few nice talks, focused on all the new and future of open and open source codecs! In fact, we will have talks about VP10, Daala, Thor and x265. https://jbkempf.com/blog/This-week-in-VideoLAN-18/ Mon, 14 Sep 2015 15:26:23 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-18/ 18th week of VideoLAN reports Here is the weekly report of what has happened in the VideoLAN community and VLC development, during the past week. Features and changes VLC The week started with the addition of a long-asked feature in VLC: hotkeys to increase and decrease the size of the subtitles, without going to preferences or restarting VLC. We then had several fixes for the Bluray support and mostly BD-J menus, that should now work correctly in VLC. https://jbkempf.com/blog/This-week-in-VideoLAN-17/ Sun, 06 Sep 2015 15:51:57 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-17/ 17th week of VideoLAN reports As this now almost an habit, here is the weekly report of what has happened in the VideoLAN community and VLC development, during the past week. You’ll see that this week has been busy on VLC’s core and the WinRT port. Features and changes VLC The week started by adding the support for the newest versions of libavcodec/libavformat, who deprecate a few API and symbols that we were using. https://jbkempf.com/blog/This-week-in-VideoLAN-16/ Tue, 01 Sep 2015 17:05:42 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-16/ 16th week of VideoLAN reports This weekly report of what’s happening in the VideoLAN community and VLC development is a bit late, because I’m in India, a bit far from a stable Internet connection :) However, here it is. You’ll see that this week has been busy on VLC’s core and the WinRT port. Features and changes VLC On Monday, Rémi rewrote the core part dealing with temporary files, introduced vlc_memfd() and rewrote the timeshifting code related to those files. https://jbkempf.com/blog/This-week-in-VideoLAN-15/ Mon, 24 Aug 2015 12:03:07 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-15/ 15th week of VideoLAN reports Yet another week, and yet another weekly report of what’s happening in the VideoLAN community and VLC development teams! We’re going back to one report per week, as holidays are over. But, to be honest, this week has not been the busiest, I guess mostly because of holidays. Features and changes VLC Yet another week started with MediaCodec fixes, which prevented all MediaCodec decoding on most Samsung devices! https://jbkempf.com/blog/Last-weeks-in-VideoLAN-14/ Mon, 17 Aug 2015 12:52:26 +0000 https://jbkempf.com/blog/Last-weeks-in-VideoLAN-14/ 14th weekly (!) report of VideoLAN This week is a bit special, since I will report about the last 2 weeks, because of lack of connectivity last week. So here is a double weekly report of what has happened in the VideoLAN community and VLC development teams! Features and changes VLC The big change of subtitles handling of the previous week involved quite a few fixes for the Closed Caption module, the tx3g codec, the freetype, quartztext and win32 text renderers. https://jbkempf.com/blog/This-week-in-VideoLAN-13/ Mon, 03 Aug 2015 20:06:23 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-13/ 13th week of VideoLAN reports Yet another week, and yet another weekly report of what’s happening in the VideoLAN community and VLC development teams! Features and changes VLC Another week started with MediaCodec fixes, which went on for a few days and terminated with the addition of hardware accelerated Audio decoding on Android. libVLC received new events for audio corking, muting, volume changing and audio devices: libvlc_MediaPlayerCorked, libvlc_MediaPlayerUncorked, libvlc_MediaPlayerMuted, libvlc_MediaPlayerUnmuted, libvlc_MediaPlayerAudioVolume, libvlc_MediaPlayerAudioDevice. https://jbkempf.com/blog/This-week-in-VideoLAN-12/ Sun, 26 Jul 2015 20:43:37 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-12/ 12th week of VideoLAN reports The summer goes on, and here I publish another weekly report of what’s happening in the VideoLAN community and VLC development teams! This week was quite cool, and quite busy, with some of the team going to Spain for aKademy Features and changes VLC The week started by the continuation of the OS X cleaning by Felix, preparing for the next releases of OS X and Xcode, removing the old QTCapture module, switching more code to ARC, splitting the code of the interface in smaller files and improve the code style of the OS X modules. https://jbkempf.com/blog/This-week-in-VideoLAN-11/ Mon, 20 Jul 2015 12:47:36 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-11/ 11th week of VideoLAN reports Yet another weekly report of what’s happening in the VideoLAN community and VLC development teams! This week was quite hot, in the real world, and we’re in the core of the summer; therefore this week was quite calm on all fronts :) Features and changes VLC A large part of the OS X interface was rewritten by Felix, to use more modern code, notably Objective 2. https://jbkempf.com/blog/This-week-in-VideoLAN-10/ Mon, 13 Jul 2015 10:50:43 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-10/ 10th week of VideoLAN reports This is my 10th weekly report of what’s happening in the VideoLAN community and VLC development teams! It’s quite cool, that I’ve been able to not drop it :) Compared to the previous week, this week was quite active, even if most changes were not very visible :) Features and changes On Monday, we removed the rest of the port of VLC on Symbian, and pushed more fixes for the OS/2 and Solaris ports. https://jbkempf.com/blog/This-week-in-VideoLAN-9/ Sun, 05 Jul 2015 21:25:55 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-9/ Yet another week in VideoLAN world Yet another week, yet another weekly report about what has happened in the VideoLAN community and VLC development teams, during the last week. As the previous week was very busy and that most Europe got a heat wave this week, this week looks almost calm. :) Features and changes VLC and libVLC The week was started by Felix updating the VDA acceleration, after the work of the previous week on VideoToolbox. https://jbkempf.com/blog/This-week-in-VideoLAN-8/ Mon, 29 Jun 2015 08:53:23 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-8/ Yet another week in VideoLAN world Another week, another weekly report about what has happened in the VideoLAN community and VLC development teams, during the last week. This week was pretty busy on most VLC related projects, as you’ll see soon. Features and changes VLC and libVLC The week started with more C11/C++11 integration, which is proving harder than expected, notably on the atomic integration side. Changes on this part went on the whole week. https://jbkempf.com/blog/This-week-in-VideoLAN-7/ Mon, 22 Jun 2015 09:26:51 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-7/ Yet another week in VideoLAN world A new week, a new weekly report about what has happened in the VideoLAN community and VLC development teams, during the last week. Features and changes VLC and libVLC Interestingly, this week was quite calmer than the previous weeks. The Direct3D11 code was modified, simplified and fixed to match the allowed WinRT APIs. The hardware decoding was also improved, to be faster to load and compile in more situations. https://jbkempf.com/blog/This-week-in-VideoLAN-6/ Sun, 14 Jun 2015 18:56:41 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-6/ Yet another week in VideoLAN world Continuing what I did for the last few weeks, and to please my friend Kostya; this post will tell you the interesting things that happened in the VideoLAN community and VLC development teams, for the last week. Features and changes VLC and libVLC The week started with a few bug fixes, notably to improve the seek over HTTP, in the mp4 demuxer, the audiotrack Android output and the iOS video output. https://jbkempf.com/blog/This-week-in-VideoLAN-5/ Tue, 09 Jun 2015 09:54:40 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-5/ Another week in VideoLAN world Continuing what I did the last few weeks, here is a new post summing up what happened, this past week, in the VideoLAN community and VLC development teams. For some technical reasons, this post was delayed a bit. I hope it won’t happen again. It still covers only what happened from Monday to Sunday, last week. Features and changes VLC and libVLC A good Monday starts with Android MediaCodec bugfixes: this time, they were mostly done in order to fix issues with the Nexus 10 tablet. https://jbkempf.com/blog/This-week-in-VideoLAN-4/ Mon, 01 Jun 2015 08:29:22 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-4/ A new week in VideoLAN world Continuing what I did the last three weeks, here is a new post summing up what happened, this past week, in the VideoLAN community and VLC development teams. VideoLAN For once, I’ll speak about the VideoLAN team before speaking about VLC. This week-end, we had the Q2 meeting of the VideoLAN non-profit organization. We met in Hamburg, hosted by Google. We spoke about VLC development, VLC new features, VLC mobile ports, libVLC, libav and the non-profit life, including the next VideoLAN Dev Days. https://jbkempf.com/blog/This-week-in-VideoLAN-3/ Sun, 24 May 2015 17:32:02 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-3/ This week in … Continuing what I did the last two weeks, here is a third post summing up what happened, this past week, in the VideoLAN community and VLC development teams. Features and changes VLC The week started with the continuation of the work on the VLC Windows threads implementation, by Rémi. In a similar way, the work on blocking SIGPIPE in libVLC went on. It went on during the whole week, notably to correctly maintain support for old BSD and OS X. https://jbkempf.com/blog/This-week-in-VideoLAN-2/ Sun, 17 May 2015 17:40:39 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-2/ This week in … Continuing what I started last week, here is a second post summing up what happened, this past week, in the VideoLAN community and VLC development teams. Features and changes VLC Monday started with fixes for UPnP on VLC, especially on Windows, due to a bug that is inside libupnp, only on Windows. It should fix most of the infamous issues, of VLC and UPnP/DLNA. The work on adaptive streaming and DASH done by François was continued. https://jbkempf.com/blog/This-week-in-VideoLAN-1/ Sun, 10 May 2015 20:51:40 +0000 https://jbkempf.com/blog/This-week-in-VideoLAN-1/ This week in … It’s can be sometimes quite difficult to follow what’s going on inside the VideoLAN community and VLC development, without reading numerous mailing lists. Therefore, I’m going to start to write a post every week doing a short summary of the interesting news. The issue, of course, lies in the fact that some weeks will be more interesting than others. :) Those kind of posts might also become a long list of unrelated things… If so, I’m sorry in advance, but I’ll do my best to just speak about the most important :) https://jbkempf.com/blog/Control-VLC-with-your-voice-and-gestures/ Sun, 03 May 2015 17:23:38 +0000 https://jbkempf.com/blog/Control-VLC-with-your-voice-and-gestures/ RealSense In VLC, we have hundreds of modules to do many crazy things, including karaoke or puzzle filter! Today, I coded 2 nice features, using Intel® RealSense™ technology: one is a voice control plugin for VLC, and the other is a gestures control plugin for VLC. With the voice control plugin, you can ask VLC to play, pause, stop, just with voice commands, like in 2001: a space Odyssey. With the gestures one, you can move your hands before the 3D camera, a la minority report. https://jbkempf.com/blog/libbluray-0.8.0/ Wed, 29 Apr 2015 14:36:54 +0000 https://jbkempf.com/blog/libbluray-0.8.0/ libbluray 0.8.0 After releasing new DVD libraries, it’s time we released new bluray libraries. :) Libbluray 0.8.0 was released a few days ago, with quite a few new features: Support for BD ISOs directly in the library, Support for streams/virtual devices, through callbacks, like we did for DVD, Support for BD-J Security Manager, to protect and isolate from security issues in the loaded Java code, Access to UDF volume identifier directly in DISC_INFO, Fixes support for Java-8 compilation. https://jbkempf.com/blog/New-DVD-releases/ Wed, 29 Apr 2015 12:17:05 +0000 https://jbkempf.com/blog/New-DVD-releases/ Past releases Following my blogpost about the history of the free DVD stack, last August, and the announces of libdvdread and libdvdnav 5.0.0, with libdvdcss 1.3.0, I kept updating the projects. libdvdnav 5.0.1/5.02 There were not many regressions in DVDnav, so I quickly released libdvdnav 5.0.1 and 5.0.2, to fix remaining crashes. libdvdread 5.0.1 However, DVDread was in a less good shape, so I released, in January, libdvdread 5.0.1 with numerous fixes and 2 minor features: DragonFly BSD bswap and a new md5 implementation. https://jbkempf.com/blog/Blu-Ray-libraries-releases/ Tue, 27 Jan 2015 13:18:58 +0000 https://jbkempf.com/blog/Blu-Ray-libraries-releases/ Blu-Ray libraries Today, we release a new version of all our Blu-Ray libraries: libbluray 0.7.0 libaacs 0.8.0 libbdplus 0.1.2 Those releases feature minor features improvements, and numerous bug fixes. The biggest changes lie on the BD-J support, Java 8 support, fonts management and the raw access to devices and filesystem. Our BD-J support should now be mostly working for most disks. The filesystem changes is preparing the development of ISO support in those libraries. https://jbkempf.com/blog/10-years-of-GSoC-and-VideoLAN/ Sun, 16 Nov 2014 10:35:01 +0000 https://jbkempf.com/blog/10-years-of-GSoC-and-VideoLAN/ Participation When GSoC started in 2005, I was not really part of the VLC community, and GSoC was a quite small program, so we did not participate at all. I joined the VLC project in 2006, but GSoC was already started and VideoLAN did not do a correct candidacy to get selected (I’m not sure it was sent at all). Starting in 2007, I took over the GSoC management, doing most of the admin, and a very large part of the mentoring of students. https://jbkempf.com/blog/Second-VLC-for-WinRT-release/ Fri, 03 Oct 2014 09:52:42 +0000 https://jbkempf.com/blog/Second-VLC-for-WinRT-release/ A new release Now, you should see a new release of VLC for WinRT on the Windows Store: 0.1.0. This is the second major release of this application. While still beta, it should be way more stable than the previous one. The major changes are: using libVLC 2.2.0 core, redesign of the interface, huge performance improvements, use of Winsock for networking instead of WinRTsock, use of Windows 8.1 widgets, move the interface code to Universal to prepare Windows Phone 8. https://jbkempf.com/blog/dvdread-dvdnav-and-dvdcss/ Sun, 27 Jul 2014 00:51:57 +0000 https://jbkempf.com/blog/dvdread-dvdnav-and-dvdcss/ History Ogle -> Xine libdvdread and libdvdnav started with the Ogle DVD player, in 1999. Ogle split libdvdread from their player and released versions 0.8.0, 0.9.0, and 0.9.1 in 2001 and early 2002. The code from Ogle was also imported and forked into the Xine project to create a xine plugin, named xine_dvdnav. The code from Xine was split into a new library: libdvdnav, in March 2002. The CVS repository was hosted in a Sourceforge project and had an actual 1. https://jbkempf.com/blog/VLC-2.1.5/ Sat, 26 Jul 2014 04:00:11 +0000 https://jbkempf.com/blog/VLC-2.1.5/ Release of 2.1.5 Today, we did a small release of the stable version of VLC media player: 2.1.5. It is just a maintenance release, before VLC 2.2.0 is ready. The highlights are: Blu-Ray subtitles (PGS) in MKV are correctly sized, Some MP3 streams could crash VLC, GPU decoding that could artefact on Windows is repaired, QTsound input does not crash anymore on OS X, Audio channels order are fixed on OS X, Improvements on the OS X UI for retina displays, We updated freetype, libass, libogg, libmodplug, live555 and libjpeg, We updated GnuTLS and libpng, to solve security issues, Various issues in interfaces and transcode chains are fixed too. https://jbkempf.com/blog/VLC-Android-and-DVDs/ Sat, 19 Jul 2014 02:39:37 +0000 https://jbkempf.com/blog/VLC-Android-and-DVDs/ Therefore, we’ve added support for DVD ISOs (encrypted or not) and DVD menus interactivity in the latest VLC for Android version (0.9.7.1). As we support full DVD ISOs, you don’t need to rip the DVD, remove the protection or do any transcoding: you just need to do an image of the DVD. This is totally legal in most countries, notably in Europe, since this is for your own usage (or your family). https://jbkempf.com/blog/Blu-Ray-libraries-update/ Sat, 12 Jul 2014 22:49:18 +0000 https://jbkempf.com/blog/Blu-Ray-libraries-update/ What’s new For libaacs and libbdplus, the updates are minor and are mostly for fixing compilation against new libgcrypt, build system issues and a speed issue in libaacs when using MMC to retrieve the MKB. For libbluray, this update is a major update. This release is the first release where the BD-J (the Java interactivity layer) is actually usable. The Java code was tested on Linux, Windows and MacOS, and it should work with J2ME and J2SE and with both the OpenJDK and Sun/Oracle’s JDK projects. https://jbkempf.com/blog/New-website-design/ Fri, 11 Jul 2014 02:44:54 +0000 https://jbkempf.com/blog/New-website-design/ My website was totally old fashioned, empty and outdated. If you’ve come here in the past, you know exactly what I mean. :D So after almost 10 years, it was time to update it. I’ve removed a lot of pages, but you can still have access to my blog, my resume, my contact information and my projects. There are still things in transitions, so it’s normal if you still see some issues. https://jbkempf.com/blog/VLC-for-Android-take-2/ Mon, 31 Mar 2014 12:01:15 +0000 https://jbkempf.com/blog/VLC-for-Android-take-2/ New interface This release has a new interface, available in dark or white colors. The UI is closer to an Android look and will evolve more in the future. Video Browser The video browser has seen a simple evolution: Audio Browser The audio browser has evolved quite a bit: We even have an equalizer: And a playlist that you can edit with gestures: Video Player We also updated the video player: Hardware acceleration The second important change is the introduction of full hardware acceleration. https://jbkempf.com/blog/Second-build-submitted-to-the-store/ Sat, 15 Mar 2014 10:47:43 +0000 https://jbkempf.com/blog/Second-build-submitted-to-the-store/ After the first beta release a couple of days ago, a second build fixing the most important crashes has been submitted to the store, for certification. It should notably fix the crash on start, on some machines, but other stability issues, on the music side too! We’d like to thank the new contributors that helped. It should appear automagically in a few hours on the store. Next release, next week! https://jbkempf.com/blog/First-achievement-unlocked/ Tue, 11 Mar 2014 02:42:45 +0000 https://jbkempf.com/blog/First-achievement-unlocked/ Features This application, version 0.2.0, is a BETA stage of the port of libVLC on WinRT. WinRT is the runtime of Windows 8/8.1 Metro/ModernUI, Windows Phone 8 and Xbox 1. As this is a beta, some features are still not perfectly stable, but we are working on that. We thought we should share it with the users, so that people could test and help us. This application: works on Windows 8. https://jbkempf.com/blog/The-state-of-the-open-Blu-Ray-playback/ Tue, 24 Dec 2013 15:50:44 +0000 https://jbkempf.com/blog/The-state-of-the-open-Blu-Ray-playback/ Releases libbluray 2013 has been a good year for libbluray. After a release in April, one in September, we just released libbluray 0.5.0! A very large part of this release is related to BD-J, the interactive menus of the Blu-Ray specification. Numerous improvements on portability, on menu support, on overlays and system integration are also part of this release. The Java part of libbluray might even work on Windows now! https://jbkempf.com/blog/Readying-VLC-on-WinRT/ Mon, 02 Dec 2013 22:46:30 +0000 https://jbkempf.com/blog/Readying-VLC-on-WinRT/ WinRT platforms So, here is an update about our port on WinRT platforms. I now say WinRT platforms, but that means: Windows 8/8.1 ModernUI Metro Windows Phone 8 XBox One? (who knows?) The WinRT platforms have mostly 2 flavors: x86 and ARM. And we’ll try to be on both of them. VLC port status We have now: support for all usual VLC formats, including MKV and FLAC, audio :D video, (with correct aspect ratios), basic subtitles support, file and network stream support, a simple, but working UI, passing the WACK certification, working on Windows 8 and 8. https://jbkempf.com/blog/VLC-2.1.1-and-2.0.9/ Thu, 14 Nov 2013 14:52:26 +0000 https://jbkempf.com/blog/VLC-2.1.1-and-2.0.9/ VLC 2.1.1 So, we’ve released today VLC 2.1.1. It’s mostly a release to fix the numerous bugs and regressions that always happen at major.0 releases. But why are there so many regressions at every major releases of VLC? The main two reasons are: we still don’t have enough people testing the prebuilt and release candidates versions… our major releases cycle is too long. While I don’t know what to do for the first, we will shorten our development cycle, starting from 2. https://jbkempf.com/blog/VLC-2.1.0-rc1/ Wed, 28 Aug 2013 12:29:31 +0000 https://jbkempf.com/blog/VLC-2.1.0-rc1/ VLC 2.1.0-rc1 I’m pleased to announce, from the VLC development team, the first release candidate of VLC media player 2.1.0, named RinceWind. This is a major version, totally more than 7000 commits, improving a lot most parts of VLC and fixing the important issues of the 2.0.x branch. Highlights Port of the VLC engine to Mobile OS, including Android, iOS (again), WinRT. This denotes new audio and video outputs, OpenGL ES improvements, including shaders; but also work on the hardware decoding for mobile. https://jbkempf.com/blog/News-about-our-WinRT-port/ Wed, 31 Jul 2013 18:07:33 +0000 https://jbkempf.com/blog/News-about-our-WinRT-port/ WinRT still advances As people who follow @videolan know, we keep working quite a bit on our port to the WinRT platforms. It is probably the port where the most effort is spent on those days, and is probably the most difficult. The good news is that we are improving quite a bit, and we are closer to having something on the store. Precision about VLC ports Some people said that we stopped working on WinRT to ship VLC on iOS… This is totally wrong, because those are not the same people working on it. https://jbkempf.com/blog/VLC-releases/ Mon, 29 Jul 2013 17:04:08 +0000 https://jbkempf.com/blog/VLC-releases/ Today, we’ve published quite a few version of VLC, for your pleasure. VLC 2.0.8 The first release is a stable release of VLC: 2.0.8. This is a necessary update to fix a few crashes and security issues that are important enough to deserve an upgrade. Moreover, as VLC 2.1.0 is slowly approaching, upgrading the stable branch is important for many GNU/Linux distributions, or for OS and architectures that won’t be supported in 2. https://jbkempf.com/blog/More-lies-from-Secunia/ Tue, 09 Jul 2013 15:41:15 +0000 https://jbkempf.com/blog/More-lies-from-Secunia/ This is a straight answer from me about the blogpost from Secunia. I will not comment much about the methods of this company or the fears they try to push onto their users. They are using the same tactics of other companies of this security business. I will therefore go straight to the point. SA51464 Intro A crashing PoC against VLC 2.0.4 was sent on the full disclosure mailing list on the December 7th. https://jbkempf.com/blog/Android-LGPL/ Wed, 19 Jun 2013 12:35:33 +0000 https://jbkempf.com/blog/Android-LGPL/ This is just a very short post (almost a bookmark-post) to share that we finished the releasing of the VLC engine on Android to LGPL. This is now live in the release that was done today, named 0.1.2. It mostly includes: the Java code in the org.videolan.libvlc namespace, the jni code gluing between libVLC and the Java code. The corresponding commits are here and there. This should allow to use the VLC engine in any other application on Android. https://jbkempf.com/blog/Follow-up-report-about-the-WinRT-port/ Mon, 29 Apr 2013 01:01:04 +0000 https://jbkempf.com/blog/Follow-up-report-about-the-WinRT-port/ News Hello, Like last post, I’ve spent too much time working on VLC than writing updates and communicating, and I’m sorry again. We are still working a lot of time, with almost a couple of persons spending most of their time on the WinRT port of VLC media player. The biggest issue is that we have not managed to pass the store validation yet, because the VLC backend is not ready yet. https://jbkempf.com/blog/New-report-about-the-WinRT-port/ Tue, 02 Apr 2013 12:47:33 +0000 https://jbkempf.com/blog/New-report-about-the-WinRT-port/ News and Excuses I must start this post by sharing some excuses of not doing enough updates lately. The main reason is that we’ve been mostly under-water with the current development, that took most of our time. News and report The good news is that we have had tremendous progress… The bad is that we have still a bit of work to do before sharing it on the store, as I will explain soon. https://jbkempf.com/blog/Over-25000/ Wed, 13 Feb 2013 16:22:22 +0000 https://jbkempf.com/blog/Over-25000/ After my 20000 mark, I have now over 25,000 posts on the Videolan Forums… You can check my profile. Of course, I am getting closer to VLC_help, who is at 25,600+ posts… And the total number of post is above 32000. The usual amount of trolls, aggressions and misunderstanding are still present, because most people still do not understand the concepts of volunteer, open source and free. But well, haters gonna hate. https://jbkempf.com/blog/Technical-update-on-the-WinRT-port/ Tue, 12 Feb 2013 00:11:19 +0000 https://jbkempf.com/blog/Technical-update-on-the-WinRT-port/ Status So, a few weeks have passed, and I have not spoken a lot about the port on WinRT/Metro/Windows RT/WP8. Of course, some of you will complain, but the main reason for that, is that I’ve been very busy on VLC :) So here is what we did :) VLC engine The biggest part of the work resides in the port of the VLC engine to a WinRT compatible runtime. https://jbkempf.com/blog/Opinion-sur-la-consultation-publique-Hadopi/ Mon, 11 Feb 2013 16:09:53 +0000 https://jbkempf.com/blog/Opinion-sur-la-consultation-publique-Hadopi/ Sur l’initiative de la consultation publique Au début de l’année 2012, VideoLAN a saisi la Hadopi, dans la cadre de sa mission de régulation des mesures techniques de protection, sur la question suivante : De quelle manière l’association VideoLAN, éditrice du logiciel libre VLC media player, peut-elle mettre à disposition des utilisateurs une version du logiciel VLC media player permettant la lecture de l’ensemble des disques couramment regroupés sous l’appellation « Blu-Ray » et comportant des mesures techniques de protection (MTP), dans le respect de ses statuts et de l’esprit du logiciel ? https://jbkempf.com/blog/Why-we-need-a-KickStarter-for-Metro/ Tue, 11 Dec 2012 16:22:19 +0000 https://jbkempf.com/blog/Why-we-need-a-KickStarter-for-Metro/ KickStarter for VLC on Metro As you might have heard, some developers of the VideoLAN team have started a kickstarter quest to crowdfound a port of VLC on WinRT. The reason for this kickstarter is that porting VLC to WinRT will be hard and long, if we don’t speed it up. And yet, quite a few people seem to think the task will be simple, like on neowin or Hacker News. https://jbkempf.com/blog/Windows-Store-and-the-GPL/ Tue, 20 Nov 2012 16:54:27 +0000 https://jbkempf.com/blog/Windows-Store-and-the-GPL/ FOSS and AppStore As more and more software distribution are going through so-called App Stores, the question about the compatibility of their terms and conditions with the open source licenses, notably the GPL, often arise. Personally I don’t like those, but I can understand why they are popular and will continue to be popular. So far, the Android store is open source friendly, and Apple one is not yet open source friendly. https://jbkempf.com/blog/How-to-properly-relicense-a-large-open-source-project-part-3/ Sat, 17 Nov 2012 00:02:51 +0000 https://jbkempf.com/blog/How-to-properly-relicense-a-large-open-source-project-part-3/ Relicensing VLC to LGPL As you might know, or might have read, I have spent a lot of my time to relicense libVLC, aka VLC engine, from GPL to LGPL. This is a continuation of the LGPL posts, please read the previous posts, if you have not done it already. Here is the last part, that should answer a few questions I’ve had. Part 3: numbers and Q/A How many lines of code were relicensed? https://jbkempf.com/blog/I-did-it/ Tue, 13 Nov 2012 23:14:47 +0000 https://jbkempf.com/blog/I-did-it/ Hello HN: you should really read part 1, part 2 and part 3 about this change. This afternoon, I finished the relicensing of most of the code of VLC to LGPL, like promised: VLC modules LGPL commit. You should read my posts on this subject. Thanks to all VLC contributors, especially the important ones! Last year, I also did the VLC core LGPL commit. https://jbkempf.com/blog/How-to-properly-relicense-a-large-open-source-project-part-2/ Thu, 08 Nov 2012 22:57:42 +0000 https://jbkempf.com/blog/How-to-properly-relicense-a-large-open-source-project-part-2/ Relicensing VLC to LGPL As you might know, or might have read, I am spending a lot of my time to relicense libVLC, aka VLC engine, from GPL to LGPL. This is a continuation of the LGPL posts, please read the previous post, if you have not done it already. So, I had a list of contributors on the parts I was considering to relicense, thanks to the previous work. https://jbkempf.com/blog/How-to-properly-relicense-a-large-open-source-project/ Wed, 07 Nov 2012 11:35:24 +0000 https://jbkempf.com/blog/How-to-properly-relicense-a-large-open-source-project/ Relicensing VLC to LGPL As you might know, or might have read, I am spending a lot of my time to relicense libVLC, aka VLC engine, from GPL to LGPL. There are quite a few good reasons to do so, some more obvious than others, but notably competition, necessity to have more professional developers around VLC and AppStores. Other reasons also exist, but this is not the place and time to discuss those. https://jbkempf.com/blog/VLC-2.0.4-and-Android-6/ Thu, 18 Oct 2012 10:08:12 +0000 https://jbkempf.com/blog/VLC-2.0.4-and-Android-6/ VLC 2.0.4 So, yet another release for VLC is around the corner. Why should you care? Well, first, it shows that the VLC project is still quite alive and that we care about our users, even if we are focusing on 2.1.0. Then, a bit of stabilization of the 2.0.x branch cannot be bad. :) For a summary of the most important features, you have: Support for Opus codec, including multi-channel and icecast streams, Support for MSS1 and MSS2 codecs through DMO on Windows and Linux (this can still be hard to use until 2. https://jbkempf.com/blog/VideoLAN-on-HTTPS/ Wed, 10 Oct 2012 21:53:58 +0000 https://jbkempf.com/blog/VideoLAN-on-HTTPS/ HTTPS, Cacert For quite a bit of time, VideoLAN had its websites available on HTTPS. This is important for forums, wiki and other places were you had to log-in to avoid passwords in clear. Unfortunately, our certificate was a Cacert certificate, which means that it was not recognized by most browsers. Then Mozilla started its fight against SSL with the most stupid UI ever (and was followed by Chrome) to force people into this SSL certificate extortion business. https://jbkempf.com/blog/News/ Tue, 02 Oct 2012 21:42:46 +0000 https://jbkempf.com/blog/News/ Phœnix (Long time no see) It has been more than 7 months that I have not blogged around VLC and VideoLAN. Why? To be honest, I have been quite busy, both professionally and personally, for the best and the worst. But the truth is that, on the little free time I had, I have been lazy, once again, and this website has not been updated :) Back! And, a contrario from the previous point, as you might have seen, I’ve been more active this year around VideoLAN and VLC. https://jbkempf.com/blog/Over-20000/ Thu, 09 Feb 2012 13:19:42 +0000 https://jbkempf.com/blog/Over-20000/ I did over 20,000 posts on the Videolan Forums to answer questions… You can check my profile. Of course, I am far under VLC_help, who is at 23,700+ posts, but still, it’s not too bad… A lot of trolls and misunderstanding are there too, because many people still do not understand the concepts of volunteer, open source and free. But well, haters gonna hate. https://jbkempf.com/blog/VLC-2.0-pour-MacOS-X/ Mon, 06 Feb 2012 11:41:42 +0000 https://jbkempf.com/blog/VLC-2.0-pour-MacOS-X/ Intro La nouvelle version de VLC, nommée TwoFlower ou 2.0, apporte de nombreuses améliorations et modifications spécifiques à MacOS X. Ce petit article permet de passer en revue ces améliorations, qui sont souvent peu décrites dans les articles plus généralistes. Ces dernières années, le développement de VLC sous OSX a été un peu chaotique et incertain, avec un vrai questionnement sur le futur du projet. Néanmoins, sur l’année passée, Félix, aidé par plusieurs autres développeurs externes, par le reste de l’équipe de VLC et par un jeune designer, a pris le taureau par les cornes. https://jbkempf.com/blog/VLC-1.2-nouveautes/ Wed, 14 Dec 2011 12:00:32 +0000 https://jbkempf.com/blog/VLC-1.2-nouveautes/ Un an et demi après la dernière version majeure (1.1.0), VLC revient avec une nouvelle version: 1.2.0, disponible en pré-version de test. L’occasion de revenir sur les nouveautés de cette version. Avec près de 8000 changements fait par 150 développeurs, 600 bugs fermés et près de 200 000 lignes de code modifiées, cette version est une des versions les plus importantes de VLC. Plus d’informations sur les contributeurs de VLC 1. https://jbkempf.com/blog/VLC-1.2.0-features-formats/ Mon, 05 Dec 2011 15:30:34 +0000 https://jbkempf.com/blog/VLC-1.2.0-features-formats/ VLC 1.2.0 I’ve spoken already about VLC 1.2.0, especially about video, video again and authoring. However, I haven’t spoken about the format supported in VLC 1.2, even if there were some hints in my last post. Discs and devices Blu-Ray One of the major cool thing of 1.2, will be a (very partial) support for Blu-Rays. Through the VideoLAN project libbluray, VLC 1.2 should be able to open unencrypted disks and backup folders. https://jbkempf.com/blog/Disc-libraries-releases/ Sat, 03 Dec 2011 12:36:00 +0000 https://jbkempf.com/blog/Disc-libraries-releases/ So, we are working quite actively on VLC 1.2. Many improvements were merged into VLC 1.2, notably for DVD and Blu-Ray playback. Therefore, there were a few releases of libraries used by VLC, lately. libbluray 0.2.1 A contrario of this weird number, this is actually the first release of libbluray that is usable. libbluray is an open-source library designed for Blu-Ray Discs playback for media players, like VLC, xine or MPlayer. https://jbkempf.com/blog/Who-wrote-VLC-1.2/ Mon, 28 Nov 2011 14:42:15 +0000 https://jbkempf.com/blog/Who-wrote-VLC-1.2/ VLC 1.2 So, VLC 1.2.x is approaching. But who wrote it? Here are some statistics computed by Rémi.

The version is now 2.4.0. All went absolutely fine, as usual, except the need to edit the config.php to add a line like this: define('DC_ADMIN_MAILFROM','foo@bar.com'); And after relogging into the admin section, a new style is there, your dotclear with the same cools things and almost the same issues… https://jbkempf.com/blog/VLC-1.2.0-part1b/ Wed, 29 Jun 2011 12:07:47 +0000 https://jbkempf.com/blog/VLC-1.2.0-part1b/ Video Output modification, continued I was previously detailing VLC 1.2.x improvements on the video output, a few weeks ago. Subtitles quality In comments, on [this blogpost](I was previously detailing) and on our IRC, people made a good point that the subtitles improvements were not enough. Indeed, compared to MPC-HC or VSFilter, the lisibility wasn’t the best, and it was notably missing a few options. Point taken Since then, VLC devs have added a few things: https://jbkempf.com/blog/VLC-1.2.0-part1/ Sun, 05 Jun 2011 14:26:24 +0000 https://jbkempf.com/blog/VLC-1.2.0-part1/ Introduction As promised in my last major post, I will try to discuss about features that are getting shaped for VLC 1.2.0. This post is therefore the first of the series. Be careful, this post is a bit technical. tl;dr version: VLC 1.2.0 will be awesome, faster and have better display quality. Video Output Rework When I joined the VideoLAN project and the VLC development team, something like 5 years ago, people were already speaking about the Video Output rework. https://jbkempf.com/blog/Dotclear-2.3/ Tue, 17 May 2011 10:48:40 +0000 https://jbkempf.com/blog/Dotclear-2.3/ Blog and dotclear As you might know, I am still running a dotclear core for the blog part of this website… The rest of the website is still some custom code written by me.

VLC VLC is doing quite well actually, but some things could be better… 1.1.0 VLC 1.1.0 was out last year, in June. This release was a tremendous success, and probably the one where we’ve had the best success for launch. The focus on GPU decoding and some HD codecs was very well welcomed by users, as was the improved Qt interface. Of course, 1.1.0 had a lot of bugs, since people still refuse to test our betas and RC versions, and as usual, 1. https://jbkempf.com/blog/HTC-Touch-Diamond-on-Windows-7/ Sat, 04 Sep 2010 08:51:32 +0000 https://jbkempf.com/blog/HTC-Touch-Diamond-on-Windows-7/ HTC Touch Diamond Thanks to a friend (Céline, you are amazing), I have now a Windows Mobile 6.1 phone: the HTC Touch Diamond. I know it is a bit old-fashioned with WM7 getting out soon, but I am not a .Net/Silverlight guy… Hands on the device The HTC device is quite classy on the outside as you can see. Reset and Start-up wizard First things first, I had reset all the data and reformat the drive, which was simple to find. https://jbkempf.com/blog/Let-s-talk-about-numbers/ Thu, 12 Aug 2010 17:25:38 +0000 https://jbkempf.com/blog/Let-s-talk-about-numbers/ VLC numbers One of the most asked question is about the VLC download numbers. Don’t ask me why, this comes all the time back on the subject. We decided for the 1.1.x releases to use the new sourceforge download service. There were 2 main reasons to do so: it provides quite interesting statistics and numbers per file, per OS, per date… it makes a 3rd party count our numbers, so we can’t be accused of cheating, as we were accused in the past. https://jbkempf.com/blog/So-I-bought-a-blu-ray-drive...2/ Sun, 08 Aug 2010 17:40:58 +0000 https://jbkempf.com/blog/So-I-bought-a-blu-ray-drive...2/ This is the follow-up to the part 1. Update to the part 1 In the first part, I was wrong when I said that there were 4 programs scheduled to start with Windows… There are 5 of them… Oh, and one of them (the LG fwupdate.exe) requires UAC to launch, and asks for permission at each start… Oh, why?!? Initial success over HDCP Whatever, I’ve spent some time to fight the HDCP problem… I will not detail all the steps I went through here, but the solution. https://jbkempf.com/blog/So-I-bought-a-blu-ray-drive.../ Thu, 05 Aug 2010 22:24:59 +0000 https://jbkempf.com/blog/So-I-bought-a-blu-ray-drive.../ Going to buy a drive Today, after getting out of work, I went to buy a Blu-Ray drive, so I can watch HD movies on my computer. My computer is a big tower, with eSata and a few drives and enough horsepower to decode those Hi-Def movies. I even have a Windows 7 on it! So, it should be working. I went to my local computer store and bought a LG drive, pretty standard one. https://jbkempf.com/blog/On-the-road-to-VLC-1.1.0-part-2-better/ Sat, 20 Mar 2010 07:52:10 +0000 https://jbkempf.com/blog/On-the-road-to-VLC-1.1.0-part-2-better/ Improvements Being faster is cool, but let’s not forget that multimedia moves fast. So here are a few improvements that you can expect in VLC 1.1.0. Codecs, demuxers and protocols In addition to than GPU/DSP decoding (see my previous post), VLC 1.1.0 will bring: DVB HD subtitles PGS Subtitles from Blu-Ray dumps sftp protocol Atrac1 audio codec Indeo5 video codec AMR (Narrow Band) audio codec Windows Media Voice/Speech audio codec Improved Flac support (7. https://jbkempf.com/blog/On-the-road-to-VLC-1.1.0-faster/ Mon, 15 Mar 2010 06:29:56 +0000 https://jbkempf.com/blog/On-the-road-to-VLC-1.1.0-faster/ Let’s go on with the first part of my articles to introduce you to VLC 1.1.0. Decoding HD In these days of HD video, speeding of decoding is more and more critical, and VLC has not shine on these aspects lately, especially on H.264. VLC 1.1 should partly fix those issues, with: faster CPU decoding, especially on Windows, GPU decoding on Windows Vista/7 and on Linux, DSP decoding with OpenMax IL on embedded Linux, like Maemo. https://jbkempf.com/blog/On-the-road-to-VLC-1.1.0-introduction/ Sat, 13 Mar 2010 13:21:18 +0000 https://jbkempf.com/blog/On-the-road-to-VLC-1.1.0-introduction/ VLC 1.0.0 The 1.0.0 version of VLC has been very popular, partly due to its stability (compared to 0.9.x) and due to its constant improvements ( revisions were 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.0.5 and soon 1.0.6). VLC 1.0.0 was out in last July, 8 month ago. We need to move on. Articles VLC 1.1.0 is on its way, and I’ll start a few articles to introduce VLC 1.1.0 features and highlights. https://jbkempf.com/blog/VLC-and-GPU-decoding-on-linux-aka-Re-Welcome-to-the-Thicket/ Sat, 30 Jan 2010 17:26:24 +0000 https://jbkempf.com/blog/VLC-and-GPU-decoding-on-linux-aka-Re-Welcome-to-the-Thicket/ Mike Melanson from FFmpeg and Adobe made a great post on hardware decoding APIs, named Welcome to the Thicket. Once again, it is quite well written, and features an awesome graph: Path chosen in VLC. As you might know, VLC 1.1 is quite closer and we have worked quite a bit on the various GPU accelerations. Windows On Windows, everything is simple, we use DxVA2. Linux On Linux, as you can see the mess on the graph. https://jbkempf.com/blog/VLC-1.0.5-et-1.1/ Sat, 30 Jan 2010 01:50:41 +0000 https://jbkempf.com/blog/VLC-1.0.5-et-1.1/ Disclaimer: Vous retrouverez cet article co-écrit par moi, sur le site de PCinpact. VLC 1.0.5 Estampillée 1.0.5, la nouvelle version de VLC est presque prête, puisque les sources sont déjà publiées. Les binaires vont suivre. Cette nouvelle version est principalement intéressante pour les utilisateurs de Windows, puisqu’elle change de compilateur et met à jour les codecs embarqués. En effet, toutes les versions depuis la 0.9.0, et notamment l’actuelle 1.0.3 (50 millions de téléchargements), ont été compilées avec la version 4. https://jbkempf.com/blog/videolan.org-stats-for-2009-90-million-visitors/ Sun, 03 Jan 2010 23:58:56 +0000 https://jbkempf.com/blog/videolan.org-stats-for-2009-90-million-visitors/ 2009, a transition year for VideoLAN As I was saying in my presentation at the VideoLAN Dev Days 2009, 2009 was an important year for VideoLAN: VideoLAN has become an non-profit organization VideoLAN Dev Days (end of ‘08) helped to structure and take decisions VLC 1.0.0 was tagged and released DVBlast and VLMC were started Acceleration of development, and communication around VLC and VideoLAN Lots of ideas for the future were discussed. https://jbkempf.com/blog/VideoLAN-is-on-Twitter/ Wed, 02 Dec 2009 14:20:54 +0000 https://jbkempf.com/blog/VideoLAN-is-on-Twitter/ You should follow us on Twitter: http://twitter.com/videolan :D https://jbkempf.com/blog/VLC-1.0.3-is-out/ Sun, 01 Nov 2009 14:40:37 +0000 https://jbkempf.com/blog/VLC-1.0.3-is-out/ Again? A release? Why ? Instead of enumerating the features that VLC 1.0.3 brings you, let’s talk about why we had to do yet another release. Speeding the development With the 1.0.x branch, we decided that we would speed up the release cycle for minor versions, for a few reasons: we didn’t want major bugs to stay around for too long, we find it easier to track regressions, we can fix crashes and potential security issues in a better timely fashion. https://jbkempf.com/blog/VLC-CDDB-on-Windows/ Tue, 27 Oct 2009 08:28:47 +0000 https://jbkempf.com/blog/VLC-CDDB-on-Windows/ CD-Audio Audio-CD have usually two main ways to get the meta-data associated with the tracks: embedded CD-Text information online, with CDDB protocol, using FreedDB VLC and Audio-CD VLC has had 2 main Audio-CD modules, named CDDA and CDDAX, one using libcdio, the other not. On windows, because of the difficulty to get libcdio, we use CDDA. But CDDA didn’t have CD-Text support. And libcddb didn’t work for us, at all. https://jbkempf.com/blog/VideoLAN-and-April/ Sat, 24 Oct 2009 01:25:56 +0000 https://jbkempf.com/blog/VideoLAN-and-April/ This is a short post topic about the VideoLAN association.

This was very funny and I met a lot of nice people. https://jbkempf.com/blog/Reflexions-about-the-first-part-of-this-SoC/ Wed, 09 Apr 2008 06:16:56 +0000 https://jbkempf.com/blog/Reflexions-about-the-first-part-of-this-SoC/ Maybe no one cares, but still here are some random thoughts about what happened so far for us. I write them now, because I might forget those when all will be over. Introduction This is the second year for VideoLAN as a mentoring organisation for the GSoC. In our first year we didn’t outperform for many reasons (see here for details VideoLAN is not a very stuctured organisation. Candidacies But this year, we received 85 candidacies (+8 ineligible) against something between 40 and 50 last year… (I fear that I don’t have the exact number ;-) ) https://jbkempf.com/blog/Nouveautes-chez-les-fabricants-de-microprocesseurs/ Wed, 09 Apr 2008 02:28:10 +0000 https://jbkempf.com/blog/Nouveautes-chez-les-fabricants-de-microprocesseurs/ L’actualité chez les fabricants américains de microprocesseurs grand public et professionnels s’est développée ces derniers jours entre nouveautés technologiques et annonces de suppression de postes. IBM Power6 IBM a présenté, mardi 8 avril, son nouveau serveur, à base de processeurs Power6, qui diminue fortement la consommation électrique grâce à plusieurs innovations. Toutefois, les performances restent au rendez-vous, puisque dans ces serveurs, le processeur peut être cadencé jusqu’à 5,0 GHz, ce qui est la fréquence la plus élevée sur le marché. https://jbkempf.com/blog/PGE-investit-dans-des-centrales-solaires/ Wed, 09 Apr 2008 02:25:29 +0000 https://jbkempf.com/blog/PGE-investit-dans-des-centrales-solaires/ PG&E, la compagnie de gaz et d’électricité du Nord de la Californie, basée à San Francisco, a annoncé des investissements importants pour la construction de centrales solaires, dans le désert du Mojave. Le fabricant des équipements sera la compagnie BrightSource, basée à Oakland (Est de la baie de San Francisco). PG&E a annoncé un investissement qui devrait aboutir à la construction de 3 centrales, dans le désert du Mojave, dans le sud de la Californie, près de la frontière avec le Nevada. https://jbkempf.com/blog/Micro-resonateurs-en-Silicium/ Mon, 31 Mar 2008 23:35:39 +0000 https://jbkempf.com/blog/Micro-resonateurs-en-Silicium/ Horloges à Quartz La plupart des appareils électroniques utilisent pour leurs horloges internes des résonateurs basés sur des cristaux à quartz. Le problème de ces cristaux à quartz réside dans la difficulté de les miniaturiser. Une équipe de chercheurs à l’université de Cornell (État de New York) a mis au point un résonateur en silicium ayant une fréquence de 4.51Ghz, ce qui pourrait améliorer la miniaturisation de ces circuits d’horloge. https://jbkempf.com/blog/25/ Sun, 30 Mar 2008 09:12:24 +0000 https://jbkempf.com/blog/25/ If you are not a geek: I am 25 If you are a geek jb.age++; https://jbkempf.com/blog/Build-VLC-media-player-under-Ubuntu-Hardy-804/ Fri, 28 Mar 2008 19:49:41 +0000 https://jbkempf.com/blog/Build-VLC-media-player-under-Ubuntu-Hardy-804/ This post is an update of the popular howto for Build VLC with feisty. Introduction So we are going to build the latest VLC possible. Everything will be done in a console/terminal and should be straight-forward. Every question should be asked on the forum, or in the comments here. Conventions Every line beginning with a # should be done as root, or using the sudo command. Every line beginning witha % is a normal line. https://jbkempf.com/blog/Mobilite-electrique-du-Graphene/ Thu, 27 Mar 2008 02:53:46 +0000 https://jbkempf.com/blog/Mobilite-electrique-du-Graphene/ Introduction sur les recherches Des chercheurs de l’université du Maryland viennent de montrer que la mobilité des électrons dans le graphène était supérieure à celle dans les autres matériaux dans des conditions de températures ordinaires. Cette découverte confirme l’intérêt porté sur ce matériau par les chercheurs et les industriels pour l’évolution des semi-conducteurs. L’équipe de recherche du Professeur Fuhrer de l’université du Maryland a publié ses résultats dans Nature Nanotechnology, en utilisant une couche fine de graphène déposée sur un substrat de Silicium. https://jbkempf.com/blog/Creation-de-centres-de-recherche-universitaire-avec-Microsoft-et-Intel/ Thu, 27 Mar 2008 01:09:19 +0000 https://jbkempf.com/blog/Creation-de-centres-de-recherche-universitaire-avec-Microsoft-et-Intel/ Multi-core et programmation Le ralentissement de l’augmentation des performances pures des processeurs et de leur montée en fréquence a poussé les fabricants de microprocesseurs à utiliser des techniques pour multiplier le parallélisme des machines. Ainsi, la multiplication du nombre de coeurs dans les microprocesseurs et l’utilisation de technologies comme l’HyperThreading (plusieurs tâches simultanées sur un seul coeur), ont augmenté le nombre de tâches que les processeurs pouvaient exécuter en parallèle et concurrentiellement. https://jbkempf.com/blog/Encheres-et-tractations-a-propos-des-frequences-sans-fils-aux-USA/ Wed, 26 Mar 2008 18:11:33 +0000 https://jbkempf.com/blog/Encheres-et-tractations-a-propos-des-frequences-sans-fils-aux-USA/ 700Mhz Les enchères pour la bande de fréquence de 700Mhz se sont closes le 18 mars dernier, après 2 mois d’enchères menés par la FCC (Federal Communications Commision). La présence de 200 entreprises, le montant total de ces enchères (le double des prévisions : 19,6 milliards de dollars), et la présence de Google en ont fait un évènement exceptionnel. Auparavant, ces fréquences étaient utilisées par la télévision analogique, pour les canaux 52 à 69. https://jbkempf.com/blog/Ventilateurs-statiques-silencieux-pour-ordinateurs/ Mon, 24 Mar 2008 16:58:21 +0000 https://jbkempf.com/blog/Ventilateurs-statiques-silencieux-pour-ordinateurs/ Semi-Therm Durant la 24ème conférence Semi-Therm, des ingénieurs et des chercheurs ont démontré un système de micro-ventilateurs, silencieux, sans parties mécaniques et mobiles, consommant peu, en utilisant l’effet corona et l’ionisation de l’air.

Au vu des dernières modifications opérées par Comcast sur son réseau et le nombre de plaintes qui s’en sont suivies, le directeur de la FCC, M. Kevin Martin, pense qu’il est nécessaire de renforcer le principe de “neutralité du Net”, voire de légiférer pour réguler les différents acteurs. Comcast La commission a reçu, dernièrement, de nombreuses plaintes contre les nouvelles politiques de Comcast. https://jbkempf.com/blog/Recuperation-des-cles-de-chiffrement-dans-les-memoires-RAM/ Thu, 28 Feb 2008 04:20:03 +0000 https://jbkempf.com/blog/Recuperation-des-cles-de-chiffrement-dans-les-memoires-RAM/ Introduction La mémoire vive des ordinateurs, contrairement à ce que l’on croit en général, ne s’efface pas instantanément après la coupure du courant. Les états mémoires restent lisibles pendant une période assez courte, mais suffisante pour une nouvelle forme d’attaque de sécurité, découverte par des chercheurs de l’université de Princeton et de l’Electronic Frontier Foundation. La mémoire reste après extinction. Lors de l’extinction d’un ordinateur, la mémoire vive (RAM) de type DRAM n’est plus rafraîchie et les données sont perdues progressivement. https://jbkempf.com/blog/MacBook-install-triple-boot-linux-windows-Mac-OS/ Wed, 27 Feb 2008 11:17:19 +0000 https://jbkempf.com/blog/MacBook-install-triple-boot-linux-windows-Mac-OS/ This details the installation of a MacBook white, shipped in the beginning of 2008. Set up Mac OS X Updates First before anything, update to the latest MacOS X.5.2, and all the necessary downloads… Reboot as many times as needed Software Then, install VLC, Firefox 3 béta, Adium and Xcode if you need it. Done. Quite easy, so far, no ?

Malgré la production de contrôleurs de carte mère (chipsets), Nvidia n’est jamais vraiment entré dans le marché des processeurs (CPU), où Intel et les constructeurs de DSP restent les leaders. Nvidia a cependant annoncé un nouveau processeur pour appareils mobiles et téléphones portables : l’APX 2500. Cette annonce suit le rachat, l’année dernière, de PortalPlayer, producteur de SoC (« System-On-Chip ») basé sur des technologies ARM. https://jbkempf.com/blog/Surveillance-de-trafic-grace-a-des-telephones-GPS/ Wed, 13 Feb 2008 19:39:20 +0000 https://jbkempf.com/blog/Surveillance-de-trafic-grace-a-des-telephones-GPS/ Expérience marrante à laquelle j’ai assisté. Le CCIT (California Center for Innovative Transportation), le département d’ingénierie civile et environnementale de Berkeley, le département des transports de Californie (Caltrans) et Nokia se sont associés, le 8 février dernier, pour réaliser une expérience grandeur nature de surveillance en temps réel du trafic autoroutier grâce à des téléphones GPS.

En utilisant la théorie des Réseaux de Markov (Markov Network ou Markov Random Field) dans chaque sous-partie de l’image pour trouver sa localisation et son orientation par rapport à ses voisins, ce modèle atteint de bien meilleures performances que ce qui avait été fait précédemment, par la même équipe et par d’autres équipes concurrentes. https://jbkempf.com/blog/Caracterisation-et-geometrie-de-lisotope-8-de-lhelium/ Wed, 30 Jan 2008 19:14:27 +0000 https://jbkempf.com/blog/Caracterisation-et-geometrie-de-lisotope-8-de-lhelium/ Le laboratoire « Argonne National Laboratory » dépendant du Department of Energy (DoE) américain, a caractérisé des atomes d’Hélium 8, l’atome le plus dense en protons. Cette réalisation et les découvertes qui en découlent devraient permettre de confirmer ou d’infirmer des théories nucléaires, et de comprendre des mécanismes des étoiles à neutrons. L’expérience, en partenariat avec le cyclotron du GANIL (Calvados), a permis de produire suffisamment d’atomes d’Hélium 8 (H8). L’originalité de la manipulation réside dans la façon de séparer les isotopes 8, qui sont les plus rares, des isotopes classiques et des isotopes 6. https://jbkempf.com/blog/Linux-2624-Intel-4965/ Fri, 25 Jan 2008 02:49:02 +0000 https://jbkempf.com/blog/Linux-2624-Intel-4965/ New Kernel : 2.6.24 If you are the happy user of a Intel 4965 AGN, rejoice, the new kernel, 2.6.24 is out and has the iwlwifi drivers inside.

Et contrairement aux autres articles, celui-ci est en français. CES 2008 Le CES de Las Vegas est le plus grand salon international portant sur l’électronique grand public. C’est un salon riche en annonces marketing mais qui présente des nouvelles technologies et dégage les grandes tendances du marché que nous allons essayer de présenter ici. Ce CES nous a montré l’omniprésence de la haute définition, la simplification des interfaces utilisateurs, la convergence des appareils et les communications inter-appareils, l’importance de la consommation d’énergie et de l’importance du design des appareils. https://jbkempf.com/blog/Innovations-technologiques-au-MacWord-2008/ Thu, 17 Jan 2008 00:37:37 +0000 https://jbkempf.com/blog/Innovations-technologiques-au-MacWord-2008/ MacWorld 2008 Le salon MacWorld, tenu à San Francisco tous les ans, est un lieu de prédilection pour Apple pour faire de grandes annonces. Le service scientifique de San Francisco a participé à la déclinaison 2008, qui n’a pas dérogé à la règle et qui présente quelques innovations technologiques notables. Les principales innovations faites par Apple concernent un ordinateur original, une technique de géo-localisation pour les possesseurs d’iPhone, des services de location de Vidéo à la demande (VOD) et un disque dur Wi-Fi. https://jbkempf.com/blog/CES-Inside-Conclusion/ Tue, 15 Jan 2008 07:21:29 +0000 https://jbkempf.com/blog/CES-Inside-Conclusion/ Personnal thought on the CES This was my first CES and my first time in Las Vegas. Las Vegas is a crazy city, to see at least once in a man’s life. I am not sure I would spend long holidays there or go there with my girlfriend/wife. But some casinos are not buildings but monuments. CES 2008 was a good show, but had some big failures: CES is too much on marketing and not enough technological for me. https://jbkempf.com/blog/CES-Inside-Day-3-Sands-south-hall/ Tue, 15 Jan 2008 07:09:01 +0000 https://jbkempf.com/blog/CES-Inside-Day-3-Sands-south-hall/ Last day in Vegas For my last day in vegas, I woke up a bit earlier than usually, checked out and went straight to the Venetian. Main Sands convention center Those stands were more numerous and smaller, and a lot from small OEM companies from south-east asia, so I was less interested by those. However, there were some cool robots, some nice iPod extensions, and a lot of gadgets everywhere. I had time to talk wiht some musicIP people. https://jbkempf.com/blog/CES-Inside-Day-2-Main-Hall-North-hall/ Tue, 15 Jan 2008 05:33:44 +0000 https://jbkempf.com/blog/CES-Inside-Day-2-Main-Hall-North-hall/ No keynotes Today, I decided to not go to the keynotes, because I was bored by the previous ones. North Hall The north hall is just about Vehicles and technologies inside those vehicles.

Download I just went to Microsoft.com and downloaded the file, which is about 340MB. Running it on my French Windows XP didn’t work because of language conflicts. Cheating French and english In order to modify the system installed locale language, run regedit, and then go to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Nls\Language registry key, and then change the value date for “Default” and “InstallLanguage” registry value to “0409“, which represent US English. https://jbkempf.com/blog/Day-of-the-cone/ Thu, 03 Jan 2008 23:15:51 +0000 https://jbkempf.com/blog/Day-of-the-cone/ Not mine.

Outre les habituels ajouts de pilotes, type de matériel et des nouvelles technologies, les fonctionnalités de gestion des multiprocesseurs et de virtualisation sont de plus en plus appréciées et regardées de près, comme les dernières sorties nous le montre. En effet, puisque les puces augmentent moins en fréquence qu’en nombre de cœurs (comme les processeurs Core 2 Duo, Core 2 Quadro, Niagara, Power6, et Phenom), les système doivent apprendre à gérer, pour des applications personnelles ( et non seulement professionnelles), plusieurs processeurs (SMP). https://jbkempf.com/blog/Cellules-solaires-organiques-en-V/ Thu, 20 Dec 2007 00:25:46 +0000 https://jbkempf.com/blog/Cellules-solaires-organiques-en-V/ Une des propriétés les plus critiques des capteurs solaires est l’efficacité des capteurs à capter l’énergie reçue et à la convertir en énergie électrique exploitable. L’équipe du professeur Peumans, de l’université de Stanford, Californie vient de démontrer comment améliorer cette efficacité pour des cellules solaires en couche mince (« thin film »). Cette étude est parue dans la dernière édition d’Applied Physics Letters. Les cellules solaires utilisées, de type organiques, souples, peu onéreuses mais peu efficaces, sont constituées de molécules, souvent des pigments ou des polymères et sont déposées sous forme de film sur un substrat, en général flexible et plat. https://jbkempf.com/blog/Configure-step-in-VLC-building/ Sat, 15 Dec 2007 05:09:40 +0000 https://jbkempf.com/blog/Configure-step-in-VLC-building/ Idea VLC can be built with a classical process: ./bootstrap; ./configure --options; make However, since VLC is very modular, not everyone wants the same modules built so the configure line can be very long. Therefore, I’ll try to explain a bit the main configure options and give a few examples.

Mac OS isn’t concerned about that change. Cocoa and CoreAnimation will remain native. Qt4 is GPL for all platforms and VLC will stay GPL for all platforms. It wasn’t like that before, but it is now true. On linux and Unix, both GUI, wx and Qt can still be compiled, so if you want a GTK only desktop, you can still use wxGTK. https://jbkempf.com/blog/SuperComputing-Open-Grid-Forum-et-Microsoft/ Wed, 21 Nov 2007 20:21:32 +0000 https://jbkempf.com/blog/SuperComputing-Open-Grid-Forum-et-Microsoft/ L’« Open Grid Forum » est un regroupement international de chercheurs, de développeurs et d’utilisateurs, basé à Chicago.

En effet, à cause de la reprise du marché des semi-conducteurs et de la pénurie de Silicium qui s’en est suivie, les prix sont passés de $25/kg en 2004 à plus de $200/kg en 2006. Ainsi, cette industrie, qui connaissait une croissance de plus de 30%, estime sa croissance pour l’année 2007 entre 10% et 20%, et semble développer les cellules à base de film, moins performantes, mais nécessitant moins de silicium. https://jbkempf.com/blog/Google-Summer-of-Code-Mentor-Summit-fr/ Wed, 07 Nov 2007 23:59:03 +0000 https://jbkempf.com/blog/Google-Summer-of-Code-Mentor-Summit-fr/ Bon, j’ai pas mal posté sur le Summer of Code en anglais, voilà un petit résumé pour les gens intéressés, mais qui sont allergiques à la langue de Shakespeare.

Just use the 0.8.6c release. However, the remote controller doesn’t work anymore and there are corruptions in the OpenGL output when you go out of fullscreen. The remote controller part should be fixed soon in VLC (development versions are fine) and the OpenGL bug, might be a problem from Leopard himself. https://jbkempf.com/blog/Mac-OS-X-Leopard/ Thu, 25 Oct 2007 22:48:44 +0000 https://jbkempf.com/blog/Mac-OS-X-Leopard/ Leopard La nouvelle version du système d’exploitation Mac OS d’Apple , sort vendredi 26 octobre 2007, demain.

Release process I was not happy with the release process. https://jbkempf.com/blog/Lutece-dOr-2007/ Thu, 14 Jun 2007 08:24:16 +0000 https://jbkempf.com/blog/Lutece-dOr-2007/ Registering for the contest As stated on IRC and mailing-lists, I registered VideoLAN to take part in the Lutece d’Or contest, that rewards Open Source developments. This contest is part of the Paris, Capitale du Libre event. I registered VLC media player as the project to compete. Nomination and award After our registration, we were nominated for Meilleur projet de développement Libre or The best Free Software development, with two other contestants. https://jbkempf.com/blog/Best-Media-Player-Software/ Wed, 06 Jun 2007 10:53:40 +0000 https://jbkempf.com/blog/Best-Media-Player-Software/ I tried a lot of different media players around the market in order to know which one is the best. Results Under Windows, WMP > BSPlayer > VLC media player Under Linux, Xine > MPlayer > VLC media player Explanations Well, this is easy, as WMP is in its 11th version, as BSPlayer is around 2.2, and VLC has not even reached version 1, the math should be easy, higher number, higher quality… No? https://jbkempf.com/blog/How-to-use-VLC-media-player-under-Vista/ Tue, 05 Jun 2007 22:11:28 +0000 https://jbkempf.com/blog/How-to-use-VLC-media-player-under-Vista/ As some of you know, there are a lot of problems to make VLC run under Vista if you have Aero enabled. UPDATE: Use VLC 0.8.6c to solve the problems and disregard the old fix. However, there might be an easy fix: Clear your preferences and cache (remove %appdata%/vlc folder) Open VLC media player, go to preferences. Tick advanced in the bottom right, Go to Advanced > CPU on the left, Untick MMX accelerations. https://jbkempf.com/blog/Bored-with-Debian-x264-patents/ Fri, 25 May 2007 13:42:25 +0000 https://jbkempf.com/blog/Bored-with-Debian-x264-patents/ I am usually a strong supporter of debian, but I may change very quickly my mind… x264 x264 was removed from debian unstable according to : http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=423250 With the very best explanation ever: Now - it contains mpeg4 stuff, try googling for “mpeg4 patent” once and you know why it needs to go out. And with the very usefull link of http://petition.eurolinux.org/pr/pr18.html. That states: the patents that will constitute the MPEG-4 Visual Patent Portfolio License support the charging of royalties on the use of MPEG-4 Visual streams in Europe" and that a license should be available within several months. https://jbkempf.com/blog/Migration-time-Ubuntu-debian/ Sun, 13 May 2007 15:43:33 +0000 https://jbkempf.com/blog/Migration-time-Ubuntu-debian/ Debian and Ubuntu migrations Spring has begun a few weeks ago and the big migration time started during april. GNU/Linux Debian etch 4.0 was out early April and Ubuntu (GNU/Linux too, even if they don’t admit it :D) too with feisty 7.04 version. I had to migrate a few machines. I am not what you can call a n00b about linux ( and debian ) administration… Ubuntu I had four machines to migrate (mostly my family’s computers). https://jbkempf.com/blog/Build-VLC-media-player-under-Ubuntu-Feisty-704/ Sun, 06 May 2007 18:14:39 +0000 https://jbkempf.com/blog/Build-VLC-media-player-under-Ubuntu-Feisty-704/ Introduction So we are going to build the latest VLC possible. Everything will be done in a console/terminal and should be straight-forward. Every question should be asked on the forum, or in the comments here. Conventions Every line beginning with a # should be done as root, or using the sudo command. Every line beginning witha % is a normal line.

Sarkozy and Royal are fighting against each other for the second round. Political PoV? Why are you speaking of politics on a VideoLAN categorie, and therefore on planet.v.o? Well, the answer is easy. I will not comment anything about their politics, because this is my opinion and it is personnal. However, the software patent is an issue that every VLC media player user should care about. https://jbkempf.com/blog/VideoLAN-What-I-have-been-doing-lately/ Mon, 23 Apr 2007 12:06:10 +0000 https://jbkempf.com/blog/VideoLAN-What-I-have-been-doing-lately/ Hello to everyone, This blog has been silent for a couple of weeks. I am so sorry. Let me explain you why. Google Summer of Code I had to finish all the stuff about the new students, a lot of discussion, reviews and choices for GSoC. All the team trusted me on the choice, so, that was difficult. But I am very happy with everything we have come up with. https://jbkempf.com/blog/Yet-another-time-copyrights-GPL-infringements-and-phishing-2/ Sat, 07 Apr 2007 03:54:36 +0000 https://jbkempf.com/blog/Yet-another-time-copyrights-GPL-infringements-and-phishing-2/ Intro After the previous post on some selling-VLC bundled with crapware using Google AdWords, here is an update. Google Contact. I contacted google through the AdWords sites but they did not really seem to understand the request and ignored it. New language. But the sites has expanded and has been translated to Portuguese and to English. Same technique, same crap. They also bought “vlc” word on Google.co.uk and Google.pt. I re-contacted google. https://jbkempf.com/blog/Yet-another-time-copyrights-GPL-infringements-and-phishing/ Wed, 28 Mar 2007 22:27:00 +0000 https://jbkempf.com/blog/Yet-another-time-copyrights-GPL-infringements-and-phishing/ Introduction iVivo If you read that blog, you might have seen the iVivo story. I did not finish that story because it was too boring, but finally they provide the code source for only $99… And their site is the same stupid things. eBay I did not blogged on eBay sellers selling VLC media player exe for $1, because this was not really a copyright infringement. And boring. other sites And we had a few GPL infringer, but a mail turned them down. https://jbkempf.com/blog/GUI-ergonomics-and-gestures/ Mon, 26 Mar 2007 09:14:43 +0000 https://jbkempf.com/blog/GUI-ergonomics-and-gestures/ Ergonomics Working on VLC media player interface, I found that clicking on menus and buttons was really un-natural. Lots of people have already said that, of course. That is why I gave a look at VLC media player Mouse Gestures. Mouse Gestures Most of the important code was already written by Dnumgis, but not the functional part. There was four gestures and I re-mapped them to have new actions. Number of actions: To ease the use of those gestures, I had decided to use only one-movements and two-movements actions, since three-movements are difficult for some people. https://jbkempf.com/blog/Help-me-with-Qt4-and-ergonomics/ Sat, 17 Mar 2007 12:20:48 +0000 https://jbkempf.com/blog/Help-me-with-Qt4-and-ergonomics/ Help me This is not a usual message for that blog, but I need some help on qt4 interface for VLC. In fact, I have most of the things done, but complex things stay, and improvement also. Moreover, I am not going fast enough. So, I am looking for people having knowledge in Qt development and willing to help me on a Free Software project… I also need ergonomics specialists, to advice me on simple problems. https://jbkempf.com/blog/Google_SoC_and_VideoLAN/ Thu, 15 Mar 2007 10:23:31 +0000 https://jbkempf.com/blog/Google_SoC_and_VideoLAN/ Google summer of code This year, Google proposes one more time the summer of code program, and I thought that VideoLAN should participate on it. Preparing it So, this year, I wrote the wiki ideas page, bother the other devs (sorry guys :D) to get, select the best ideas (with the team) and discuss with everyone. We found mentors and backup mentors and build a few very interesting projects. Then, last week, a night, when I was in Paris for the Journées FedeRez , I applied and answered to the questions on the application form. https://jbkempf.com/blog/Eric-Raymond-leaves-Fedora-and-multimedia-codecs/ Thu, 01 Mar 2007 13:02:54 +0000 https://jbkempf.com/blog/Eric-Raymond-leaves-Fedora-and-multimedia-codecs/ History Do you remember, Eric Raymond (ESR), “the cathedral and the bazaar” writer, mailed all of us on his departure of Fedora? I will not comment on the man and the hello-look-I-am-here-and-everyone-should-do-the-same and I-post-my-life-on-all-mailing-list-attitudes, because it is boring. This was last week, initial announcement and there were a lot of answers, but I liked the Alan Cox answer the most. Alan Cox answer: On Wed, Feb 21, 2007 at 03:03:50AM -0500, Eric S. https://jbkempf.com/blog/Comment-retrouver-ses-donnees-en-plus-de-30-secondes/ Thu, 01 Mar 2007 12:51:29 +0000 https://jbkempf.com/blog/Comment-retrouver-ses-donnees-en-plus-de-30-secondes/ Bon, la dernière fois , j’avais perdu toutes mes données sur un crash de PC. J’avais donc perdu Mon disque principal (Mail, Documents, Systèmes, Projets en cours…) Mon disque de backup Mon disque de photo avait des erreurs… Bref, en gros, plus de mail, plus de contacts, plus de documents, et presque plus de photos. Et mon disque principal ne s’alimentait plus, il était grillé ! Un nouveau disque dur. Grâce à eBay, j’ai retrouvé, grâce à mon ami Prof, un disque dur dont les caractéristiques techniques étaient identiques, et les numéros de séries, les PCB et le WDM très proches! https://jbkempf.com/blog/How-to-install-VLC-086a-under-ubuntu-dapper-606-LTS/ Wed, 28 Feb 2007 14:23:23 +0000 https://jbkempf.com/blog/How-to-install-VLC-086a-under-ubuntu-dapper-606-LTS/ Howto install VLC 0.8.6 under dapper I hope that you are able to deal with a computer, synaptic or sources.list Add a new repository Add deb ftp://ftp.videolan.org/pub/videolan/ubuntu dapper universe to you/etc/apt/sources.lists or synaptic.

It has been annonced on vlc-devel mailing list. Wiki A lot of work has been done by H2g2bob and myself in order to: Provide correctly thought access pages (Main Page and Developers mainly) for the content and the design. Provide a lot of new pages : we have over 250 pages! Provide a lot of new categories, links to wikipedia and Multimedia’s Wiki, new templates. https://jbkempf.com/blog/Qt4-Interface/ Mon, 12 Feb 2007 15:38:24 +0000 https://jbkempf.com/blog/Qt4-Interface/ Qt4 Interface I am going to speak a bit of the new Qt-based interface and the FUD I have seen around this future interface. A new UI should be shipped with VLC media player version 0.9.0. First, it will be shipped in parallel to the wxWidgets Interface Then, it will replace totally the wx Interface. Why ? This is the most asked question… There are a few answers: We had a lot of problems with right-to-left languages, We had a lot of problems with Unicode and Wide-Characters support, We lacked a few features, We needed to enhance this UI, and the main coder left, To test something new. https://jbkempf.com/blog/2007-0.8.6a-release/ Thu, 08 Feb 2007 13:40:23 +0000 https://jbkempf.com/blog/2007-0.8.6a-release/ A Bugfix Release Intro Everything was going great under the best world. VLC 0.8.6 was out during December without a lot of troubles, with a lot of fixes… A mature release, but… Initial report Month of Apple Bugs has started on the first of January. And the second day was a VLC security problem. First, we did not think that we could be targeted, because we are not an Apple company… On the same day, there was a patch on the mailing-list. https://jbkempf.com/blog/Bonne-annee-Happy-New-Year/ Thu, 01 Feb 2007 00:13:38 +0000 https://jbkempf.com/blog/Bonne-annee-Happy-New-Year/ Bonne année Happy new year Bon, cette année, plein de changements en perspectives, des bons et des moins bons. Au niveau du travail, il est indéniable que des changements auront lieu. Je pars bientôt à Grenoble et je prépare mon départ. Tous mes voeux ! So this year, I’ll change town, I’ll finish my studies and I’ll travel a lot.

You will also see that Developers’ site is at work. I’ll do a lot of Categories, rewrite, change modifications in the next week in order to give this wiki a good look. I am planning to do cross links and move developers.videolan.org from where it is now. Results in a few weeks.

The new release (0.8.6) has been released less than one week ago, and is already over 1 million downloads. And a lot of them haven’t been counted because of the website being down. Long life to this release. Next version Next version of VLC wil be 0.9.0 - Grishenko. I can already told you that it will have: A new GUI using Qt4 libraries instead of WxWidgets, I hope a new default skin, if we agree in the Team, A new documentation Fullscreen controls ? https://jbkempf.com/blog/VLC-release/ Tue, 12 Dec 2006 12:26:02 +0000 https://jbkempf.com/blog/VLC-release/ VLC 0.8.6 was released yesterday. For me, it is a very special release, because it is the first release I really feel from the inside. However, this release is a bit a bastard release, since the main upgrades are from FFMPEG updates or only for Mac Users. And there are a lot of bugfixes, that will help the forum to be a bit less overloaded. I am waiting so much to see next release (0. https://jbkempf.com/blog/De-retour-de-Vacances/ Tue, 12 Dec 2006 12:01:05 +0000 https://jbkempf.com/blog/De-retour-de-Vacances/ Je rentre tout juste d’un petit trip dans le grand Nord. J’ai été retrouvé Baptiste et des copains à lui pour me balader en Scandinavie. Au programme, j’ai fait : Oslo, quelques jours pour visister et rencontrer les amis de Baptiste; Evenes, dans le nord de la norvège, où a atteri notre avion; Puis bus et train pour aller à Narvick, puis Abisko en Suède, où nous sommes arrêtés plus longuement; Nous avons continué sur Kiruna, et l’hôtel de glace et le froid; Après un long voyage en train, arrivée à Stockholm, visite de la ville; Retour à Paris pour le WED. https://jbkempf.com/blog/VLC-Name/ Thu, 30 Nov 2006 01:50:50 +0000 https://jbkempf.com/blog/VLC-Name/ VLC’s official name is “VLC media player”. That may seem weird, but that is true. In fact, for many people VLC means VideoLAN Client, like in the old days… But the name has changed. So they don’t understand that VLC is not just a player, but also a streaming server, and a transcoding software… Those people still compare VLC to mplayer when they should compare it to mplayer + mencoder or to WMP + WME. https://jbkempf.com/blog/VLC-QA-team/ Wed, 15 Nov 2006 18:01:46 +0000 https://jbkempf.com/blog/VLC-QA-team/ I am going to try to set a Quality Assurance team for VLC. I will start on the wiki. I am therefore looking for volunteers to improve VLC’s releases.

A lot of features that are asked are already in VLC (like flv, wmv, extra audio…) Full-screen buttons and control Full-screen buttons and control :D This is marked twice since this feature is a lot more asked than the others. Browser plugin buttons and control If this plugin could detect and replace flash player or embedded windows media player, it would great. https://jbkempf.com/blog/GPL-iVivo/ Wed, 15 Nov 2006 01:48:11 +0000 https://jbkempf.com/blog/GPL-iVivo/ Disclaimer IANAL Long post. Introduction As you know, VLC media player and VideoLAN’s documentation are licenced under the GNU/GPL. But one person has, on Videolan’s Forum, told us that iVivo was re-distributing VLC. We answered that we would investigate… iVivo iVivo is an Israëli company that has registered http://ivivo.net, http://ivivo.org, and http://ivivo.tv, and has its website located on yahoo servers. It is supposed to be based in Tel-Aviv.

This does not mean 26 million people use VLC, since a few things are corrupting the statistics: this only count direct or mirror downloads, which means that unofficial mirrors, big download sites that use a replica of the files are not counted ! as usual, VLC in linux distributions are not countable since most of the greatest distribution use some repository for their files; 1 download ! https://jbkempf.com/blog/Un-nouveau-blog/ Thu, 09 Nov 2006 01:33:29 +0000 https://jbkempf.com/blog/Un-nouveau-blog/ Voilà, le nouveau look du site est en place!
