When saving AVIF with ICC profile, RGB_to_YcbCr conversion is done according r\*0.299f + g\*0.587f + b\*0.114f coefficients. This represents matrix coefficients 6 (BT.601).
Unfortunately other AVIF…

Right now, both the encoder and the decoder contain both the encoder and decoder.
If I build the encoder with `CONFIG_AV1_DECODER` and `CONFIG_AV1_HIGHBITDEPTH=0` in the AOM build, it knocks around…

Currently rav1e refuses to encode inputs smaller than 16px in width or height. This is problematic for AVIF support, because tiny images like that are sometimes used.
If it's not too hard, could yo…
