This problem is common to all recent releases of ffmpeg (even the lastest 0.7) - they dropped the 'medium' preset. There are two fixes: (i.) The arch way - create ~/.ffmpeg/medium.ffpreset containing only a comment line (with '#' as the first character). Ffmpeg still puts some presets in /usr/share/ffmpeg so it is _possible_ that you could do the same thing there. (ii.) Patch transcode. The patch from debian (attached here) appears to solve the problem [ gentoo have a different patch, which for me prevented a segfault but did not help ]. You might also need to build libmpeg2 [ 0.5.1 is in the book ] and then rebuild transcode adding --enable-libmpeg2 --enable-libmpeg2convert to the configure options. For me, using libmpeg2 didn't seem to help in any of my tests, but YMMV. ĸen -- das eine Mal als Tragödie, das andere Mal als Farce
