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