Comment (by pdr0):
That issue is fixed when using -c:v libaom-av1 -aom-params lossless=1
I participated in that thread and revisited it just now
I also tested a few different samples (patterns, and real), 8bit and
10bit, all more than 8frames, and all were lossless with the -aom-params
lossless=1 switch. Confirmed "lossless" using ffmpeg psnr, and using
methods outside of ffmpeg
Do you have a test source that is "not lossless" with -aom-params
lossless=1 (1st frame or not) ?
