But what you don't say is that many of these are either definitely dead (mplayer2 comes to mind), or are ancient releases of software which fixed their API usage later (like my own project, and probably most other reasonable active projects). Why do we have to suffer because Debian tries to compile ancient releases against newer ffmpeg/libav releases? (How does that even make sense?) And then there's the category of projects that are "alive", but barely care about anything unless being severely prodded. I'm not sure why we should suffer forever just to accommodate these projects. They had more than enough time. I feel like I'm repeating myself and others, but I don't remember whether you acknowledged these arguments. > Better documentation would surely be helpful. Many of these are non-trivial. Project authors either update their code, or the project dies. It's simple. If you don't want this, keep an old ffmpeg/libav package around for them. But you distro peoples want a single libavcodec package, no matter how much this fucking tortures everyone. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
