Comment (by domingo):

 Original MP4 video track contains 3 pairs of [SPS][PPS] NAL units causing
 H264 reinit.
 Pair 1 is duplicate, but pairs 2 and 3 are different from what is put into
 MP4 META information (avcC box).
 In general, MP4 track should not contain SPS nor PPS units.
 Is there any way to ignore them while decoding MP4 video tracks?
