HEVC Decoder Configuration Record ISO/IEC 14496-15:2022(E) - 8.3.2.1

Fields

configuration_version: u8

The configuration_version as a u8. Matches the field as defined in ISO/IEC 23008-2.

general_profile_space: u8

The general_profile_space as a u8. Matches the field as defined in ISO/IEC 23008-2.

general_tier_flag: bool

The general_tier_flag as a bool. Matches the field as defined in ISO/IEC 23008-2.

general_profile_idc: u8

The general_profile_idc as a u8. Matches the field as defined in ISO/IEC 23008-2.

general_profile_compatibility_flags: u32

The general_profile_compatibility_flags as a u32. Matches the field as defined in ISO/IEC 23008-2.

general_constraint_indicator_flags: u64

The general_constraint_indicator_flags as a u64. Matches the field as defined in ISO/IEC 23008-2.

general_level_idc: u8

The general_level_idc as a u32. Matches the field as defined in ISO/IEC 23008-2.

min_spatial_segmentation_idc: u16

The min_spatial_segmentation_idc as a u16. Matches the field as defined in ISO/IEC 23008-2.

chroma_format_idc: u8

The chroma_format_idc as a u8. Matches the field as defined in ISO/IEC 23008-2.

bit_depth_luma_minus8: u8

The bit_depth_luma_minus8 as a u8. Matches the field as defined in ISO/IEC 23008-2.

bit_depth_chroma_minus8: u8

The bit_depth_chroma_minus8 as a u8. Matches the field as defined in ISO/IEC 23008-2.

parallelism_type: u8

The parallelism_type as a u8.

0 means the stream supports mixed types of parallel decoding or otherwise.

1 means the stream supports slice based parallel decoding.

2 means the stream supports tile based parallel decoding.

3 means the stream supports entropy coding sync based parallel decoding.

avg_frame_rate: u16

The avg_frame_rate as a u16.

constant_frame_rate: u8

The constant_frame_rate as a u8.

0 means the stream might have a constant frame rate.

1 means the stream has a constant framerate.

2 means the representation of each temporal layer in the stream has a constant framerate.

num_temporal_layers: u8

The num_temporal_layers as a u8. This is the count of tepmoral layers or sub-layers as defined in ISO/IEC 23008-2.

0 means the stream might be temporally scalable.

1 means the stream is NOT temporally scalable.

2 or more means the stream is temporally scalable, and the count of temporal layers is equal to this value.

temporal_id_nested: bool

The temporal_id_nested as a bool.

0 means means the opposite might not be true (refer to what 1 means for this flag).

1 means all the activated SPS have sps_temporal_id_nesting_flag (as defined in ISC/IEC 23008-2) set to 1 and that temporal sub-layer up-switching to a higehr temporal layer can be done at any sample.

length_size_minus_one: u8

The length_size_minus_one is the u8 length of the NALUnitLength minus one.

arrays: Vec<NaluArray>

The arrays is a vec of NaluArray. Refer to the NaluArray struct in the NaluArray docs for more info.

Implementations

impl HEVCDecoderConfigurationRecord

pub fn demux(data: &mut Cursor<Bytes>) -> Result<Self>

Demuxes an HEVCDecoderConfigurationRecord from a byte stream. Returns a demuxed HEVCDecoderConfigurationRecord.

pub fn size(&self) -> u64

Returns the total byte size of the HEVCDecoderConfigurationRecord.

pub fn mux<T: Write>(&self, writer: &mut T) -> Result<()>

Muxes the HEVCDecoderConfigurationRecord into a byte stream. Returns a muxed byte stream.

Trait Implementations

impl Clone for HEVCDecoderConfigurationRecord

fn clone(&self) -> HEVCDecoderConfigurationRecord

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HEVCDecoderConfigurationRecord

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for HEVCDecoderConfigurationRecord

fn eq(&self, other: &HEVCDecoderConfigurationRecord) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
