HEVC Decoder Configuration Record.

ISO/IEC 14496-15 - 8.3.2.1

Fields

general_profile_space: u8

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

general_tier_flag: bool

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

general_profile_idc: u8

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

general_profile_compatibility_flags: ProfileCompatibilityFlags

Matches the general_profile_compatibility_flag field as defined in ISO/IEC 23008-2.

general_constraint_indicator_flags: u64

This is stored as a 48-bit (6 bytes) unsigned integer. Therefore only the first 48 bits of this value are used.

general_level_idc: u8

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

min_spatial_segmentation_idc: u16

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

parallelism_type: ParallelismType

See ParallelismType for more info.

chroma_format_idc: u8

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

bit_depth_luma_minus8: u8

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

bit_depth_chroma_minus8: u8

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

avg_frame_rate: u16

Gives the average frame rate in units of frames/(256 seconds), for the stream to which this configuration record applies.

Value 0 indicates an unspecified average frame rate.

constant_frame_rate: ConstantFrameRate

See ConstantFrameRate for more info.

num_temporal_layers: NumTemporalLayers

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

temporal_id_nested: bool

Equal to true indicates that all SPSs that are activated when the stream to which this configuration record applies is decoded have sps_temporal_id_nesting_flag as defined in ISO/IEC 23008-2 equal to true and temporal sub-layer up-switching to any higher temporal layer can be performed at any sample.

Value false indicates that the conditions above are not or may not be met.

length_size_minus_one: u8

This value plus 1 indicates the length in bytes of the NALUnitLength field in an HEVC video sample in the stream to which this configuration record applies.

For example, a size of one byte is indicated with a value of 0. The value of this field is one of 0, 1, or 3 corresponding to a length encoded with 1, 2, or 4 bytes, respectively.

arrays: Vec<NaluArray>

NaluArrays in that are part of this configuration record.

Implementations

impl HEVCDecoderConfigurationRecord

pub fn demux(data: impl Read) -> 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.
