AV1 encode & decode build issue

[waiwaiwai]

iirc adding '--psnr' will output the PSNR after encoding.

Cu Selur

I do added the --psnr into my command line, it will only output the average PSNR at the end of encoding without per frame PSNR.
Is there a command for per frame PSNR? and I tried adding the >PSNR.log at the end of command but nothing is logged to the file.
