Oh, I see.
Hi, Rostislav Pehlivanov, please tell me your idea.
(How can I address him/her in ML...?)
I think it is more useful to execute this line when "-crf 0" is set:
> codecctl_int(avctx, AV1E_SET_LOSSLESS, ctx->lossless);
It could let use

I forgot to say that if "-lossless 1" is set, "crf" will also be 0 (in
libaom, internally).
All those conditions will be forced (ot at least checked by libaom) if we
execute this line:
> codecctl_int(avctx, AV1E_S

That was my question, sorry for being unclear.

No. "crf 0" has the same meanings. It just makes the quality better than
"crf 1".
I read libaom again, and I apologize for my wrong explanation:
I found that if certain conditions are met, "crf 0" also generates
lossless vi

Unfortunately, crf=0 is not lossless.
"lossless" flag uses "quantisation matrices", which is different from the
default quantizer determined by "-crf", to achieve lossless encoding.

AV1 support lossless encoding.
In this patch, I added a command line flag to enable it.
