Old description:
> Summary of the bug:
>
> PES in this sample starts with 5th packet (counting from 1) with
> prepended 4 bytes of TP_extra_header 0x2647B960. If you edit in hex
> editor 5th packet to 0x2648B960 (so 0x47 is gone) the files decoded in
> full, the same as in TsMuxer. If you edit it after PES it is wrong, if
> you edit any packet before PES (even the first 4 bytes of file itself) it
> is fixed. You can use DVB Inspector 1.19.1 (you need last version, since
> before it was printing TP_extra_header wrong).
>
> How to reproduce (the actual file produced should be bigger, 9 059 073
> bytes):

New description:
Summary of the bug:
PES in this sample starts with 5th packet (counting from 1) with prepended
4 bytes of TP_extra_header 0x2647B960. If you edit in hex editor 5th
packet to 0x2648B960 (so 0x47 is gone) the file's decoded in full, the
same as in TsMuxer. If you edit it after PES it is wrong, if you edit any
packet before PES (even the first 4 bytes of file itself) it is fixed. You
can use DVB Inspector 1.19.1 (you need last version, since before it was
printing TP_extra_header wrong).
How to reproduce (the actual file produced should be bigger, 9 059 073
bytes):

Patch is here, but it is clearly suboptimal. You only have to check
packets behind PES and including PES (so you check whether it is M2TS
extension and default to 192 or instead check that 5th byte of the file is
0x47 and if one of first 4 bytes are also 0x47 you need to write a
separate codepath that will carefully examine and remove TP_extra_header,
if any of TP_extra_headers no longer have 0x47 bytes you do not have to
worry no more).
What is even easier is to not take into account first (for start of
parsing, whether it is stream or file) 4 bytes at all assuming 5th is
0x47, as that also fixed the issue.
