Sorry, I should have typed '-f framemd5'.  That's generates a file containing the
audio and video checksums.

What I'd like to know is how the audio packets work.  They obviously don't
correspond to video frames in a 1-to-1 fashion, since there are more audio
packets then video packets.  And since the number of audio packets isn't
an integer multiple of the number of frames, then they can't correspond
to video packets in an n-to-1 fashion.  However, they must corresponds ]
to frames in some way.  Does that make any sense?
