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}
41 force displayed height
43 Set frame size (WxH or abbreviation), needed for videos which don't
44 contain a header with the framesize like raw YUV.
50 seek to a given position in seconds
54 disable graphical display
59 @section Advanced options
61 @item -pix_fmt @var{format}
64 Show the stream duration, the codec parameters, the current position in
65 the stream and the audio/video synchronisation drift.
67 print specific debug info
71 visualize motion vectors
73 non-spec-compliant optimizations
77 Force RTP/TCP protocol usage instead of RTP/UDP. It is only meaningful
78 if you are streaming with the RTSP protocol.
79 @item -sync @var{type}
80 Set the master clock to audio (@code{type=audio}), video
81 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
82 master clock is used to control audio-video synchronization. Most media
83 players use audio as master clock, but in some cases (streaming or high
84 quality broadcast) it is necessary to change that. This option is mainly
85 used for debugging purposes.
