Hehe, none taken. To my defense, I did that in about an hour, using Marillat's packages... :) > Thus I have started from scratch and packaged FFmpeg 2.1.3 [1] (see > attached debian.tar.xz).

Fair enough - there could be a qt-faststart binary package which could conflict with libav-tools. > The libraries are build with --enable-raise-major, which bumps the > sonames by 100 to get i.e. libavcodec155, thus avoiding conflicts. > Note that there is also --enable-incompatible-libav-abi that would allow > packages build against libav to be used with the ffmpeg library, but > upstream thinks this would not work the other way round as well.

I don't see why security would complain: as things stand there are hundreds of security issues that have been fixed in ffmpeg (see the Google audit) which have not been fixed in libav... It seems to me ffmpeg is only more secure than libav at this point... > I think this package is ready for upload, but I'm neither DD nor DM, so > I can't do this. I would be hesistant in doing so, considering the controversy, but if we reach consensus here, i'd be happy to sponsor it. > Rogério, Jackson are you willing to review my packaging and then > upload/maintain it?
