pub fn codec_utils_h265_get_profile(
    profile_tier_level: &[u8]
) -> Result<GString, BoolError>
Expand description

Converts the profile indication (general_profile_idc) in the stream’s profile_level_tier structure into a string. The profile_tier_level is expected to have the following format, as defined in the H.265 specification. The profile_tier_level is viewed as a bitstream here, with bit 0 being the most significant bit of the first byte.

  • Bit 0:1 - general_profile_space
  • Bit 2 - general_tier_flag
  • Bit 3:7 - general_profile_idc
  • Bit 8:39 - gernal_profile_compatibility_flags
  • Bit 40 - general_progressive_source_flag
  • Bit 41 - general_interlaced_source_flag
  • Bit 42 - general_non_packed_constraint_flag
  • Bit 43 - general_frame_only_constraint_flag
  • Bit 44:87 - See below
  • Bit 88:95 - general_level_idc

§profile_tier_level

Pointer to the profile_tier_level structure for the stream.

§Returns

The profile as a const string, or None if there is an error.
