[FFmpeg-user] Audio Packets, Video Packets, md5 output

With ffmpeg, I generate an md5 file with the following command:
ffmpeg -i IN.avi -mdf OUT.md5
The OUT.md5 file contains checksums for both the video and audio packets. The
video checksums makes sense (to me): there is one for each frame in the input (the
AVI file stores each frame in full, so there's no inter-frame compression).
However, there's about twice as many audio packets as video packets. Why is
that? How can I tell which audio packet corresponds to a video frame? How
are the audio packets created?
