Target platforms in order of importance - Ubuntu, Raspbian, OSXīasically, my shortcoming at this point is not understanding the relationship of FourCC code (as a parameter to OpenCV VideoWriter) to the FFMPEG backend and its requirements. I am trying to get OpenCV VideoWriter work across platform consistently for MP4 container with H246 encoding. ![]()
