EOR frames MUST be zero-length and must be set keyframe. All streams SHOULD end with EOR, where the pts of the EOR indicates the end presentation time of the final frame.

2*max_distance ?
ok
Why is it 2* ? Why not just max_distance?
the syncpoint distance is a tradeoff between resync ability after ANY error and overhead
the value here is a tradeoff between detecting rare damaged framesize and overhead so it makes sense to have this larger, and why not yet another variable, well if we cant decide what value is good how should a poor muxer?
That's a poor argument, by the same logic we could hard code in spec max_distance, max_pts_distance, and the entire frame code table... I say make it another variable, reccommend in spec it should be no more than ~2*max_distance ... (also, a per stream variable. I think it is best like this) - ods15
