Thanks, I've already checked https://github.com/lemenkov/libyuv it is faster then FFMPEG, but slower then GPU conversion. Do the developers plan to implement fast software RGB=YUVconversion in FFMPEG in future? Is sws_scalse obsolete? Anywhere, when I am encoding video with FFMPEG h264_nvenc on GPU, I want to do conversion RGB to NV12 with GPU too. Is it possible with FFMPEG now?
