VideoLAN Announces Dav1d, a New Libre and Open Source AV1 Decoder (jbkempf.com)
Jean-Baptiste Kempf, president of VideoLan and developer of VLC media player, made the following announced Monday: AV1 is a new video codec by the Alliance for Open Media, composed of most of the important Web companies (Google, Facebook, Netflix, Amazon, Microsoft,...). AV1 has the potential to be up to 20% better than the HEVC codec, but the patents license is totally free, while HEVC patents licenses are insanely high and very confusing.
The reference decoder for AV1 is great, but it's a research codebase, so it has a lot to improve. Therefore, the VideoLAN, VLC and FFmpeg communities have started to work on a new decoder, sponsored by the Alliance of Open Media. The goal of this new decoder is: be small, be as fast as possible, be very cross-platform, correctly threaded, libre and (actually) Open Source. Without further due, the code: https://code.videolan.org/videolan/dav1d Recommended: A talk during VDD 2018 conference about dav1d. -
Open-Source Blu-Ray Library Now Supports BD-J Java
An anonymous reader writes: Updates to the open-source libbluray, libaacs, and libbdplus libraries have improved the open-source Blu-ray disc support to now enable the Blu-ray Java interactivity layer (BD-J). The Blu-ray Java code is in turn executed by OpenJDK or the Oracle JDK and is working well enough to play a Blu-ray disc on the Raspberry Pi when paired with the VLC media player." -
VLC Finally Launches App For Windows 8
SmartAboutThings writes "After a long journey of more than one year, which included even a successfully ended Kickstarter campaign, the VLC app for Windows 8 is officially here. VLC for Windows 8 is currently in beta, and it lacks some important features, such as the ability to open music files or support for Windows RT devices. On the good side, VLC for Windows 8 supports the same codecs as the VLC application for desktop, from MPEG-1 to H.265, through WMV3 and VC-1; it also supports multiple-audio tracks selection, embedded subtitles, background audio playback, Live Tiles, removable storage and DLNA servers." -
VLC And Secunia Fighting Over Vulnerability Reports
benjymouse writes "Following a blog post by security company Secunia, VideoLAN (vendor of popular VLC media player) president Jean-Baptiste Kempf accuses Secunia of lying in a blog post titled 'More lies from Secunia.' It seems that Secunia and Jean-Baptiste Kempf have different views on whether a vulnerability has been patched. At one point VLC threatened legal action unless Secunia updated their SA51464 security advisory to show the issue as patched. While Secunia changed the status pending their own investigation, they later reverted to 'unpatched.' Secunia claimed that they had PoC illustrating that the root issue still existed and 3rd party confirmation (an independent security researcher found the same issue and reported it to Secunia)." There are two bugs: one is a vulnerability in ffmpeg's swf parser that vlc worked around since they don't support swf. The VLC developers think Secunia should have reported the bug to ffmpeg, which seems pretty sensible. The other bug is an uncaught exception in the Matroska demuxer with overly large chunks that merely results in std::terminate being called; the Matroska demux maintainer apologized, but, despite dire warnings from Secunia that it could be exploitable, it most certainly is not.
