I think the problem with doing that would be that you'd be decoding from the 
last keyframe for every frame you asked for, regardless of whether you'd 
recently passed through this frame en route to another. This would work, and 
certainly be better than nothing, especially for people like me who deal 
mainly in I-frame formats, but I can't help thinking there ought to be a 
better way.
