}

The AVC (H.264) Decoder Configuration Record. ISO/IEC 14496-15:2022(E) - 5.3.2.1.2

Fields

configuration_version: u8

The configuration_version is set to 1 (as a u8) defined by the h264 spec until further notice.

ISO/IEC 14496-15:2022(E) - 5.3.2.1.2

profile_indication: u8

The profile_indication (aka AVCProfileIndication) contains the profile_idc u8 from SPS.

ISO/IEC 14496-15:2022(E) - 5.3.2.1.2

profile_compatibility: u8

The profile_compatibility is a u8, similar to the profile_idc and level_idc bytes from SPS.

ISO/IEC 14496-15:2022(E) - 5.3.2.1.2

level_indication: u8

The level_indication (aka AVCLevelIndication) contains the level_idc u8 from SPS.

ISO/IEC 14496-15:2022(E) - 5.3.2.1.2

length_size_minus_one: u8

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

ISO/IEC 14496-15:2022(E) - 5.3.2.1.2

sps: Vec<Bytes>

The sps is a vec of SPS Bytes.

Note that these should be ordered by ascending SPS ID.

Refer to the crate::Sps struct in the SPS docs for more info.

pps: Vec<Bytes>

The pps is a vec of PPS Bytes.

These contain syntax elements that can apply layer repesentation(s).

Note that these should be ordered by ascending PPS ID.

ISO/IEC 14496-15:2022(E) - 5.3.2.1.2

extended_config: Option<AvccExtendedConfig>

An optional AvccExtendedConfig.

Refer to the AvccExtendedConfig for more info.

Implementations

impl AVCDecoderConfigurationRecord

pub fn parse(reader: &mut Cursor<Bytes>) -> Result<Self>

Parses an AVCDecoderConfigurationRecord from a byte stream. Returns a parsed AVCDecoderConfigurationRecord.

pub fn size(&self) -> u64

Returns the total byte size of the AVCDecoderConfigurationRecord.

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

Builds the AVCDecoderConfigurationRecord into a byte stream. Returns a built byte stream.

Trait Implementations

impl Clone for AVCDecoderConfigurationRecord

fn clone(&self) -> AVCDecoderConfigurationRecord

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AVCDecoderConfigurationRecord

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

Formats the value using the given formatter.

impl PartialEq for AVCDecoderConfigurationRecord

fn eq(&self, other: &AVCDecoderConfigurationRecord) -> 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.
