It's typical for these game-oriented formats to not specify keyframes 
(other than the first frame). The keyframe flag is advisory to FFmpeg, 
but it will do fine without it. Also, keyframes only apply to video 
frames, not audio.

I wish I could answer more of your questions but I have been out of the 
internals for awhile. Thanks for your work on this format.
