Some codecs have two modes: one with global extradata used in formats optimized for storage, one without used in formats optimized for streaming. You are probably getting the later and trying to use where the former is needed. You probably need to insert one of the mp4toannexb bitstream filters. (I wonder why it is not done automatically as it is done for AAC.) Regards, -- Nicolas George
