AV1 Codec Configuration Record

https://aomediacodec.github.io/av1-isobmff/#av1codecconfigurationbox-syntax

Fields

seq_profile: u8

This field shall be coded according to the semantics defined in AV1.

3 bits

seq_level_idx_0: u8

This field shall be coded according to the semantics defined in AV1.

5 bits

seq_tier_0: bool

This field shall be coded according to the semantics defined in AV1, when present. If they are not present, they will be coded using the value inferred by the semantics.

1 bit

high_bitdepth: bool

This field shall be coded according to the semantics defined in AV1.

1 bit

twelve_bit: bool

This field shall be coded according to the semantics defined in AV1, when present. If they are not present, they will be coded using the value inferred by the semantics.

1 bit

monochrome: bool

This field shall be coded according to the semantics defined in AV1, when present. If they are not present, they will be coded using the value inferred by the semantics.

1 bit

chroma_subsampling_x: bool

This field shall be coded according to the semantics defined in AV1, when present. If they are not present, they will be coded using the value inferred by the semantics.

1 bit

chroma_subsampling_y: bool

This field shall be coded according to the semantics defined in AV1, when present. If they are not present, they will be coded using the value inferred by the semantics.

1 bit

chroma_sample_position: u8

This field shall be coded according to the semantics defined in AV1, when present. If they are not present, they will be coded using the value inferred by the semantics.

2 bits

hdr_wcg_idc: u8

The value of this syntax element indicates the presence or absence of high dynamic range (HDR) and/or wide color gamut (WCG) video components in the associated PID according to the table below.

HDR/WCG IDC	Description
0	SDR
1	WCG only
2	HDR and WCG
3	No indication

2 bits

From a newer spec: https://aomediacodec.github.io/av1-mpeg2-ts/#av1-video-descriptor

initial_presentation_delay_minus_one: Option<u8>

Ignored for MPEG-2 TS use, included only to aid conversion to/from ISOBMFF.

4 bits

config_obu: BytesCow<'a>

Zero or more OBUs. Refer to the linked specification for details.

8 bits

Trait Implementations

impl<'a> Clone for AV1CodecConfigurationRecord<'a>

fn clone(&self) -> AV1CodecConfigurationRecord<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for AV1CodecConfigurationRecord<'a>

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

Formats the value using the given formatter.

impl<'a> Deserialize<'a> for AV1CodecConfigurationRecord<'a>

fn deserialize<R>(reader: R) -> Result<Self>

where R: ZeroCopyReader<'a>,

Deserialize a value from the given zero-copy reader.

impl IsoSized for AV1CodecConfigurationRecord<'_>

Available on crate feature isobmff only.

fn size(&self) -> usize

Returns the size of the AV1 Codec Configuration Record.

impl<'a> PartialEq for AV1CodecConfigurationRecord<'a>

fn eq(&self, other: &AV1CodecConfigurationRecord<'a>) -> 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.

impl Serialize for AV1CodecConfigurationRecord<'_>

fn serialize<W>(&self, writer: W) -> Result<()>

where W: Write,

Serialize the value into the given writer.
