Description

Currently there is no option to specify chroma subsampling when encoding using libaom-av1, and 4:2:0 is used by default. Settings for 4:0:0 (monochrome), 4:2:2 and 4:4:4 should be added.

The color config semantics for AV1 are here specified (large document): https://aomediacodec.github.io/av1-spec/#color-config-semantics

Chroma subsampling is set by choosing output AVPixelFormat.
