21 @c man begin DESCRIPTION
23 FFplay is a very simple and portable media player using the FFmpeg
24 libraries and the SDL library. It is mostly used as a testbed for the
31 @include fftools-common-opts.texi
37 Force displayed width.
39 Force displayed height.
41 Set frame size (WxH or abbreviation), needed for videos which don't
42 contain a header with the frame size like raw YUV.
48 Seek to a given position in seconds.
49 @item -t @var{duration}
50 play <duration> seconds of audio/video
54 Disable graphical display.
57 @item -window_title @var{title}
58 Set window title (default is the input filename).
59 @item -loop @var{number}
60 Loops movie playback <number> times. 0 means forever.
61 @item -vf @var{filter_graph}
62 @var{filter_graph} is a description of the filter graph to apply to
64 Use the option "-filters" to show all the available filters (including
65 also sources and sinks).
69 @section Advanced options
71 @item -pix_fmt @var{format}
74 Show the stream duration, the codec parameters, the current position in
75 the stream and the audio/video synchronisation drift.
77 Print specific debug info.
81 Visualize motion vectors.
83 Non-spec-compliant optimizations.
87 Force RTP/TCP protocol usage instead of RTP/UDP. It is only meaningful
88 if you are streaming with the RTSP protocol.
89 @item -sync @var{type}
90 Set the master clock to audio (@code{type=audio}), video
91 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
92 master clock is used to control audio-video synchronization. Most media
93 players use audio as master clock, but in some cases (streaming or high
94 quality broadcast) it is necessary to change that. This option is mainly
95 used for debugging purposes.
96 @item -threads @var{count}
98 @item -ast @var{audio_stream_number}
99 Select the desired audio stream number, counting from 0. The number
100 refers to the list of all the input audio streams. If it is greater
101 than the number of audio streams minus one, then the last one is
102 selected, if it is negative the audio playback is disabled.
103 @item -vst @var{video_stream_number}
104 Select the desired video stream number, counting from 0. The number
105 refers to the list of all the input video streams. If it is greater
106 than the number of video streams minus one, then the last one is
107 selected, if it is negative the video playback is disabled.
108 @item -sst @var{subtitle_stream_number}
109 Select the desired subtitle stream number, counting from 0. The number
110 refers to the list of all the input subtitle streams. If it is greater
111 than the number of subtitle streams minus one, then the last one is
112 selected, if it is negative the subtitle rendering is disabled.
114 Exit when video is done playing.
116 Exit if any key is pressed.
117 @item -exitonmousedown
118 Exit if any mouse button is pressed.
121 @section While playing
140 Cycle subtitle channel.
146 Seek backward/forward 10 seconds.
149 Seek backward/forward 1 minute.
152 Seek to percentage in file corresponding to fraction of width.
