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

37 Force displayed width.
39 Force displayed height.
41 This option has been removed. Use private format options for specifying the
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 -showmode @var{mode}
62 Set the show mode to use.
63 Available values for @var{mode} are:
70 show audio frequency band using RDFT ((Inverse) Real Discrete Fourier Transform)
73 Default value is "video", if video is not present or cannot be played
74 "rdft" is automatically selected.
76 You can interactively cycle through the available show modes by
77 pressing the key @key{w}.
79 @item -vf @var{filter_graph}
80 @var{filter_graph} is a description of the filter graph to apply to
82 Use the option "-filters" to show all the available filters (including
83 also sources and sinks).
85 @item -i @var{input_file}
86 Read @var{input_file}.

95 Show the stream duration, the codec parameters, the current position in
96 the stream and the audio/video synchronisation drift.
100 Non-spec-compliant optimizations.
104 Force RTP/TCP protocol usage instead of RTP/UDP. It is only meaningful
105 if you are streaming with the RTSP protocol.
106 @item -sync @var{type}
107 Set the master clock to audio (@code{type=audio}), video
108 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
109 master clock is used to control audio-video synchronization. Most media
110 players use audio as master clock, but in some cases (streaming or high
111 quality broadcast) it is necessary to change that. This option is mainly
112 used for debugging purposes.
113 @item -threads @var{count}
114 Set the thread count.
115 @item -ast @var{audio_stream_number}
116 Select the desired audio stream number, counting from 0. The number
117 refers to the list of all the input audio streams. If it is greater
118 than the number of audio streams minus one, then the last one is
119 selected, if it is negative the audio playback is disabled.
120 @item -vst @var{video_stream_number}
121 Select the desired video stream number, counting from 0. The number
122 refers to the list of all the input video streams. If it is greater
123 than the number of video streams minus one, then the last one is
124 selected, if it is negative the video playback is disabled.
125 @item -sst @var{subtitle_stream_number}
126 Select the desired subtitle stream number, counting from 0. The number
127 refers to the list of all the input subtitle streams. If it is greater
128 than the number of subtitle streams minus one, then the last one is
129 selected, if it is negative the subtitle rendering is disabled.
131 Exit when video is done playing.
133 Exit if any key is pressed.
134 @item -exitonmousedown
135 Exit if any mouse button is pressed.
138 @section While playing
157 Cycle subtitle channel.
163 Seek backward/forward 10 seconds.
166 Seek backward/forward 1 minute.
169 Seek to percentage in file corresponding to fraction of width.
