Thanks for these references.
Therefore I don't consider this problem currently as release-critical. That would be different, if libavcodec-extra was the default.I strongly believe that you are mistaken. Please do try to elaborate if you still, based on above, think Debian need not care.
I never thought that Debian wouldn't have to care about this issue, but I thought it's not important enough to prolong Debian's freeze.
As I understand it, the fix would be to add a Provides to libavcodec-extra-56 and add Conflicts to affected GPL v2 programs.
If that can be done for jessie as well, all the better.
If you are interested in fixing license issues, feel free to take care of removing the non-distributable image tests/lena.pnm [1] from the libav source package.1: https://en.wikipedia.org/wiki/File:Lenna.png#LicensingThanks for bringing that to my attention. I am very surprised you do not want to report that bug yourself.
When I became aware of this problem (and convinced FFmpeg upstream to accept a patch [2] fixing it), I feared that it wouldn't be appreciated if I filed such a bug against the libav package.
I will now do that.
Thanks. Best regards, Andreas2: https://git.videolan.org/?p=ffmpeg.git;a=commit;h=c4abee734dcbdb589925dd6da98041dcf663ce49
