--- Comment #33 from Aaron Boxer <boxerab at gmail.com> ---
So, reading the beginning of the PES header in method mpegts_parse_pes_header,
I get the following bytes:

0x80 0x0a 0x1b 0xd2 0xbd 0xfe

0x80 is a flag indicating a PTS, but the next byte
should have its low bit set.  Since it doesn't, the PTS
is rejected.

This byte pattern appears for each PES packet, so it doesn't look like
corruption, as it is the same pattern.

I am not familiar enough with mpeg ts to see what is going on here.....

By the way, I also see this:

#define ST_PS_VIDEO_MPEG2_DCII          0x80

Is this a private video stream, perhaps, rather than a PTS ?
