Thanks, I will probably 'use' mpeg4 in my application (Divx4/5, lavc, or xvid)
and will have to live with that this is complicated because I want to use
mplayer for this and not waste time and resources on using one tool for encoding
and one for getting those images (e.g I could perhaps use transcode or another
tool for getting the image I want from each movie).
