Such claims may be enforceable in countries like the United States which have implemented software patents, but are considered unenforceable or void in countries that have not implemented software patents. Many codecs that compress information have been claimed by patent holders. The MPV media player no longer supports Libav due to missing API changes. MPlayer2, a defunct fork of MPlayer, used Libav exclusively, but could be used with GStreamer with its public API. Software using Libav instead of FFmpeg ĭebian followed Libav when it was announced, and announced it would return to FFmpeg for Debian Stretch (9.0). For example, the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project. To further complicate matters, Libav chose a name that was used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc.). Starting with Ubuntu 15.04 "Vivid", FFmpeg's ffmpeg is back in the repositories again. In June 2012, on Ubuntu 12.04, the message was re-worded, but that new "deprecated" message caused even more user confusion.
This message was removed upstream when ffmpeg was finally removed from the Libav sources. This confused some users into thinking that FFmpeg (the project) was dead. During the transition period, when a Libav user typed ffmpeg, there was a message telling the user that the ffmpeg command was deprecated and avconv has to be used instead. Libav then renamed their ffmpeg to avconv to distance themselves from the FFmpeg project. Finally, FFmpeg supported a far wider variety of codecs and containers than Libav.Īs of 2022, Libav is an abandoned software project, with Libav developers either returning to FFmpeg, moving to other multimedia projects like the AV1 video codec, or leaving the multimedia field entirely.Īt the beginning of this fork, Libav and FFmpeg separately developed their own versions of the ffmpeg command. Secondly, Mateusz "j00ru" Jurczyk, a security-oriented developer at Google, argued that all issues he found in FFmpeg were fixed in a timely manner, while Libav was still affected by various bugs. Firstly, FFmpeg had a better record of responding to vulnerabilities than Libav. On July 8, 2015, Debian announced it would return to FFmpeg for various, technical reasons. Hence, most software on these systems that depended on FFmpeg automatically switched to Libav. The maintainer of the FFmpeg packages for Debian and Ubuntu, being one of the group of developers who forked FFmpeg, switched the packages to this fork in 2011.
FFMPEG MP4 H264 CODE
The event was related to an issue in project management and different goals: FFmpeg supporters wanted to keep development velocity in favour of more features, while Libav supporters and developers wanted to improve the state of the code and take the time to design better APIs. It was announced on Maby a group of FFmpeg developers. The Libav project was a fork of the FFmpeg project. 1.3 Software using Libav instead of FFmpeg.
