[FFmpeg-user] capture from camera (macOS) and pass video to ffplay

[Peter Gusev]

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)?

Thanks!
