Hi there! I need to capture video from a camera (macOS) and then pass it through a file pipe to ffplay for displaying it. Can't figure out how to specify ffmpeg's output pixel format. When passing -pix_fmt argb ffmpeg says that the format is incompatible with the input device (?). I expect ffmpeg to transcode whatever incoming pixel format is to the one I specified so that I can have ffplay read from file pipe like this "ffplay -f rawvideo -vcodec rawvideo -s 320x180 -i file_pipe". Also, can ffmpeg write to a file pipe (not the pipe: <http://ffmpeg.org/ffmpeg-protocols.html#pipe> functionality)?
