13 @c man begin DESCRIPTION
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}
37 force displayed height
39 Set frame size (WxH or abbreviation), needed for videos which don't
40 contain a header with the framesize like raw YUV.
46 seek to a given position in seconds
50 disable graphical display
55 @section Advanced options
60 Show the stream duration, the codec parameters, the current position in
61 the stream and the audio/video synchronisation drift.
63 print specific debug info
67 visualize motion vectors
69 non-spec-compliant optimizations
73 Force RTP/TCP protocol usage instead of RTP/UDP. It is only meaningful
74 if you are streaming with the RTSP protocol.
76 Set the master clock to audio (@code{type=audio}), video
77 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
78 master clock is used to control audio-video synchronization. Most media
79 players use audio as master clock, but in some cases (streaming or high
80 quality broadcast) it is necessary to change that. This option is mainly
81 used for debugging purposes.
86 @section While playing
108 seek backward/forward 10 seconds
111 seek backward/forward 1 minute
