14 FFplay is a very simple and portable media player using the FFmpeg
15 libraries and the SDL library. It is mostly used as a testbed for the
24 ffplay [options] @file{input_file}
39 force displayed height
41 Set frame size (WxH or abbreviation), needed for videos which don't
42 contain a header with the framesize like raw YUV.
48 seek to a given position in seconds
52 disable graphical display
57 @section Advanced options
59 @item -pix_fmt @var{format}
62 Show the stream duration, the codec parameters, the current position in
63 the stream and the audio/video synchronisation drift.
65 print specific debug info
69 visualize motion vectors
71 non-spec-compliant optimizations
75 Force RTP/TCP protocol usage instead of RTP/UDP. It is only meaningful
76 if you are streaming with the RTSP protocol.
77 @item -sync @var{type}
78 Set the master clock to audio (@code{type=audio}), video
79 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
80 master clock is used to control audio-video synchronization. Most media
81 players use audio as master clock, but in some cases (streaming or high
82 quality broadcast) it is necessary to change that. This option is mainly
83 used for debugging purposes.
