> Can you apply your patch?
I'm not sure what you want from me. I've posted the patch. It just needs
to be reviewed/pushed.
> just check the fifth byte is 0x47 and then check that 4 previous bytes
are not 0x47
You're misunderstanding the problem. Your bug occurs when the 5th byte is
where the TS packet starts, and it's prefixed by 4 bytes of
TP_extra_header and those 4 bytes happen to include the sync byte.
Skipping the first four bytes for 192 bytes packets is the fix, no need to
backtrack or anything like that.
