Miscellany

On my FreeBSD machine (using manually compiled ffmpeg from svn):

$ ffmpeg -i 79.wmv -s 440x330 -b 10000 -deinterlace -qscale 6 -acodec mp3 -ar 22050 -ab 96K -f flv 79.flv

On my Gentoo machine it does work (using the latest ffmpeg version they have in portage):

$ ffmpeg -i 79.wmv -s 440x330 -b 10000 -deinterlace -qscale 6 -acodec mp3 -ar 22050 -ab 96K -f flv 79.flv
