Comment:
We wait for a keyframe before we start writing to the file. However for
H.264 (at least) we do not discover that the current AU (frame) is a
keyframe until several packets into the AU. We are supposed to buffer all
the packets of the AU, but that is not working, so the file ends up
missing the first part of the AU, rendering that keyframe as undecodable.
