it works with svn for flv video; theora video, however; still doesn't
care about the quantizer:


for x in 1 5 25; do /home/nido/bin/programs/ffmpeg/bin/ffmpeg -y -vframes 250 -i in.flv -qscale $x -s vga   out$x.flv; done
for x in 1 5 25; do /home/nido/bin/programs/ffmpeg/bin/ffmpeg -y -vframes 250 -i in.flv -qscale $x -s vga   out$x.flv; done
ls -lh
