Comment (by Balling):

 Replying to [comment:18 cehoyos]:
 > To make a lossless AV1 encode with libaom using the ffmpeg binary,
 neither a new encoder option nor a private library option are needed.

 Well, -crf 0 or even -b:v 0 -crf 0 do not work.

 >private library option

 That one does it exist?

 >Encoding with libaom via FFmpeg is not lossless by default

 Oh, do you think I did not know that? Seriously? Do you also think I do
 not know that by default hevc is not lossless? Or VP9? Or AVC? Wow, just
 wow.
