#939863

Tiens c’est nouveau ça. Quelle version d’ubuntu tu as ? (moi il ne me dit plus rien depuis que la date de fin de support est passée, d’ailleurs).

This message is rather misleading and understandably is a source of confusion. Ubuntu now uses libav which is a fork of the FFmpeg project. The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. (It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to libav on his own accord probably due to being involved with the libav fork.)

For a while both libav and FFmpeg separately developed their own versions of ffmpeg. libav then renamed their ffmpeg to avconv to distance themselves from the FFmpeg project. During the transition period the message you see was displayed to tell users to start using avconv instead their version of ffmpeg. This confuses some users into thinking that FFmpeg (the project) is dead, which is not true. Unfortunate wording, but I can’t imagine libav not expecting such a response by general users.

This message was removed upstream when ffmpeg was finally removed from the libav source, but it still shows up in Ubuntu because the libav source Ubuntu uses is from the ffmpeg-to-avconv transition period. After some back-and-forth it was decided to change the wording, but as of 2012-05-15 the fix is still currently “in progress” for Ubuntu Precise (see Ubuntu bug #939863).
