The squeeze packages come from the original ffmpeg.org version of FFmpeg
(no avconv), but the squeeze-backports package derives from the
libav.org fork of FFmpeg. Making things slightly more complicated is
the fact that the forks have different version histories even though the
two repositories have cross-pollinated. Version 0.8 from libav.org
(squeeze-backports version) isn't the same as version 0.8 from
ffmpeg.org. The new filter argument syntax appeared in the 0.9 branch
of the ffmpeg.org repository, but it's in the 0.8 branch of the
libav.org repository, and thus appears in the squeeze-backports build.
Clear as mud, n'est-ce pas?
Debian and Ubuntu switched to the libav.org fork in early 2011 after the
Great FFmpeg Schism. A cursory search suggests RPM-based distros like
Fedora and OpenSUSE are still using the ffmpeg.org version, so there
shouldn't be any problems there. I think everything should be OK for
you and other Debian/Ubuntu users - without any changes to get_iplayer -
so long as libav.org continues to provide an ffmpeg binary. Famous last
