I don't know how to do it, but it sounds like the original poster wants a variation on "ffmpeg -i video.mpg -f image2 -qscale1 outfile-%05d.jpeg" such that the output contains the unadulterated I, P, or B frames (not jpeg files) with the filenames indicate whether they are I, P, or B frames. Abeer, is that correct?
