codecUtilsH264GetProfile

fnstring codecUtilsH264GetProfile(ubyte[] sps)

Converts the profile indication (profile_idc) in the stream's sequence parameter set into a string. The SPS is expected to have the following format, as defined in the H.264 specification. The SPS is viewed as a bitstream here, with bit 0 being the most significant bit of the first byte.

  • Bit 0:7 - Profile indication
  • Bit 8 - constraint_set0_flag
  • Bit 9 - constraint_set1_flag
  • Bit 10 - constraint_set2_flag
  • Bit 11 - constraint_set3_flag
  • Bit 12 - constraint_set3_flag
  • Bit 13:15 - Reserved
  • Bit 16:24 - Level indication

Parameters

spsPointer to the sequence parameter set for the stream.

Returns

The profile as a const string, or null if there is an error.
