       ffplay - FFplay media player

       ffplay [options] input_file

       FFplay is a very simple and portable media player using the FFmpeg
       libraries and the SDL library. It is mostly used as a testbed for the
       various FFmpeg APIs.

       Main options

       -h  Show help.

	   Show version.

       -L  Show license.

	   Show available formats, codecs, protocols, ...

       -x width
	   Force displayed width.

       -y height
	   Force displayed height.

       -s size
	   Set frame size (WxH or abbreviation), needed for videos which don't
	   contain a header with the frame size like raw YUV.

       -an Disable audio.

       -vn Disable video.

       -ss pos
	   Seek to a given position in seconds.

	   Seek by bytes.

	   Disable graphical display.

       -f fmt
	   Force format.

       Advanced options

       -pix_fmt format
	   Set pixel format.

	   Show the stream duration, the codec parameters, the current posi‐
	   tion in the stream and the audio/video synchronisation drift.

	   Print specific debug info.

	   Work around bugs.

	   Visualize motion vectors.

	   Non-spec-compliant optimizations.

	   Generate pts.

	   Force RTP/TCP protocol usage instead of RTP/UDP. It is only mean‐
	   ingful if you are streaming with the RTSP protocol.

       -sync type
	   Set the master clock to audio ("type=audio"), video ("type=video")
	   or external ("type=ext"). Default is audio. The master clock is
	   used to control audio-video synchronization. Most media players use
	   audio as master clock, but in some cases (streaming or high quality
	   broadcast) it is necessary to change that. This option is mainly
	   used for debugging purposes.

       -threads count
	   Set the thread count.
