Has anyone ever tested the compression ratio of nvenc? I tried to test the performance of NVEnc using rigaya/NVEnc. Below is the download address of rigaya/NVEnc.
I tested hevc and h264. But the pompression ratio of hevc was lower than that of h264. It is quite strange.
NVEncC64.exe --input-res 3840x2160 --fps 30 --raw --input-csp yuv420p -i D:\Test\asia.yuv -c hevc --cqp 26:26:26 -u performance -b 0 --gop-len 256 --mv-precision Q-pel --tier high -o D:\asia.h265
