All MXF is based on UID which are keys of 16 bytes. If wish I could use
int128_t. I still can build a nice table of UID recognized and use
memcmp, do you think that would be cleaner ?

I just tried to factorize and only check of variable patterns.

Hehe. I fully undertand the point here, but how this is comparable to
the asserts in mov.c checking the time_rate ?

Also about the assert checking bytes_num at the top. I have no type
bigger than int64_t in C. Im lost. I'll just stop using asserts for now
I think :>
