Does anyone have an M2TS raw parser? Lacking that, does anyone have a map of M2TS so I can parse

Try searching for "m2ts parser". One of the first hits I got was this:
https://github.com/daniep01/MPEG-2-Transport-Stream-Packet-Analyser
No idea if it does what you want, you'll just have to look.
Thanks, Hans,
It parses only PES headers, not GOPs. It shows the 188 bytes and some of the info in those bytes,
but it doesn't match the info to the byte -- no map -- so, it's useless to me. Even if showed the
GOP header, I wouldn't know which bytes were which tag.
You can't search for a hex string like 00 00 01 B8 (which is the GOP header
start code).
And it's very, very slow -- it's written in visual basic.
So, it's not a parser. It's more like a TS-packet browser.
