how to identify H.264 profile

[Sip-implementors] H.264 in SIP - question about profile-level-id

1. hexdump -C test.mp4 | less
2. search for profile-level-id=4dE01E

You should refer to ITU-T H.264 standard

From the document
Baseline profile: profile_id 66 = 0x42
Main profile: profile_id 77 = 0x4D
Extended profile: profile_id 88 = 0x58
