Description Edward Hervey 2011-04-29 11:38:50 UTC 
mpegvideoparse is scanning for all start codes twice. Once when buffers are
added to the packetizer and once again when parsing for picture data.

When handling picture data, we only need to find the MPEG_PACKET_PICTURE data
to scan the header (and not all the remaining picture start codes that we
will be discarding).

Makes mpegvideoparse two times faster on HD content
