[Libav-user] AVCHD m2ts magic number?

[cyril apan]

There isn't any real magic number for m2ts files. Those files are raw MP4 Part 12 streams without headers. As such streams usually start with a sync byte (value of a sync byte is always 0x47),  you can consider this to be the magic number you were after.
Cheers,
Cyril APAN.
