>>I'm using FFMPEG/sws_scale to convert PixFmt from RGB to YUV(NV12) (Without size scaling!) .
>>It is really a bottleneck of the encoding process, it is extremely slow!!
>>What I'm doing wrong? Should I use another FFMPEG convert method instead of sws_scale?
>>I've checked the OBS studio source code and found that they use a self-written RGB-NV12 converter instead of using FFMPEG/sws_scale.
