Wondering how can I start a constant quality encoding using aomenc.exe

[ceshiwenfq]

Hey guys ,I'm just going to give it a shot ,see how aomenc performs in 2020.

However after downloaded aomenc.exe & carefully studied "aomenc.exe --help" , I couldn't find any settings about qp mode , I've just found tow params probably related to output quality ,which are "--end-usage=" & "--target-bitrate="

I'm wondering how can I achieve a same result as when I'm using e.g. "x265 --crf 20" ,without manually specify a output bitrate (Since it's usually hard to findout what bitrate those group of picutres should be.)

Need help ,thanks.
