Struct Av1MetadataObu 

pub struct Av1MetadataObu {
    pub metadata_type: u8,
    pub extension_flag: bool,
    pub payload: Vec<u8>,
}

A minimal AV1 METADATA_OBU wrapper.

AV1 metadata OBUs (type 5) carry a metadata_type varint followed by the payload. This struct uses a simple fixed-length encoding for the metadata type (1 byte) to keep the implementation patent-free and simple.

Fields

metadata_type: u8

AV1 metadata type. Commonly 4 (ITUT T35) or 5 (custom).

extension_flag: bool

OBU extension byte present flag.

payload: Vec<u8>

Serialised SEI payload.

Implementations

impl Av1MetadataObu

pub fn new(metadata_type: u8, payload: Vec<u8>) -> Self

Wrap a pre-serialised SEI payload into a METADATA_OBU.

pub fn to_bytes(&self) -> Vec<u8>

Serialise to a byte slice ready for muxing.

Wire format:

[obu_header: 1 byte][extension? 1 byte if extension_flag][metadata_type: 1 byte][payload...]

pub fn from_bytes(raw: &[u8]) -> CodecResult<Self>

Parse an AV1 METADATA_OBU from raw bytes.

Trait Implementations

impl Clone for Av1MetadataObu

fn clone(&self) -> Av1MetadataObu

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Av1MetadataObu

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

Formats the value using the given formatter.

impl PartialEq for Av1MetadataObu

fn eq(&self, other: &Av1MetadataObu) -> 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.
