Luma8 direct encoding without conversion in AVIF

Open MimoKar opened this issue 6 months ago • 1 comments

I would like to be able to encode the pure grayscale as 8bpp in AVIF if possible with rav1e, or in YUV400 at least.

I have a lot of grayscale images (manga scans) and they are encoded always in YUV444p. This I see as not needed in these cases as it is using a lot more space.
