slower than opencv

Tested on raspberry pi 4b, it's 3x slower than OpenCV's cvtColor function call. cv::cvtColor(m, fout->m_, cv::COLOR_YUV2BGR_I420, 3);

how to match output with input in mmal

Example of the frame:  I have a USB camera that outputs mjpeg frames that fail to be decoded by mmal. I have tried to use hello_mmal_jpeg, hello_mmal_video,...
