Codec Parameters represent the codec major capabilities needed to decode like codec/codec subtype and profiles/levels.
For example string "avc1.640028" represents H264:- – stream-format avc1 – profile 4.0 which is derived from 2 bytes bytes(base16) in the sequence "640028" – profile_idc identified by "64" which indicates "High Profile". – level_idc which is "28" and 40 in decimal which means 4.0.
