Expand description

The av1C AV1 codec configuration.

This is the bridge between the two specifications AVIF is made of: it declares the AV1 profile and sample format, and carries the sequence header OBU that the bitstream decoder needs before it can read a frame.

Fields§

§seq_profile: u8

AV1 sequence profile, 0–2.

§seq_level_idx0: u8

AV1 level index.

§seq_tier0: u8

AV1 tier.

§bit_depth: u8

Bits per sample: 8, 10 or 12.

§subsampling: Subsampling

How chroma is sampled.

§chroma_sample_position: u8

Chroma sample position, 0–3.

§config_obus: Vec<u8>

The OBUs carried in the configuration record itself.

Normally the sequence header, so a decoder can be configured before it reaches the frame data in mdat.
