Really, this libav is a shame. This doesn't happen with the actual libav* from ffmpeg. Now I have a lot of tools in Debian which I need to use to get some work done... and they just fail again, again and again because libav.

Can we really drop this buggy fork called 'libav' and go back to ffmpeg.. or at least allow users to switch to a working libav*? See also bug #729203
