17 @c man begin DESCRIPTION
19 FFplay is a very simple and portable media player using the FFmpeg
20 libraries and the SDL library. It is mostly used as a testbed for the
27 @include avtools-common-opts.texi
33 Force displayed width.
35 Force displayed height.
37 Set frame size (WxH or abbreviation), needed for videos which do
38 not contain a header with the frame size like raw YUV. This option
39 has been deprecated in favor of private options, try -video_size.
45 Seek to a given position in seconds.
46 @item -t @var{duration}
47 play <duration> seconds of audio/video
51 Disable graphical display.
54 @item -window_title @var{title}
55 Set window title (default is the input filename).
56 @item -loop @var{number}
57 Loops movie playback <number> times. 0 means forever.
58 @item -showmode @var{mode}
59 Set the show mode to use.
60 Available values for @var{mode} are:
67 show audio frequency band using RDFT ((Inverse) Real Discrete Fourier Transform)
70 Default value is "video", if video is not present or cannot be played
71 "rdft" is automatically selected.
73 You can interactively cycle through the available show modes by
74 pressing the key @key{w}.
76 @item -vf @var{filter_graph}
77 Create the filter graph specified by @var{filter_graph} and use it to
78 filter the video stream.
80 @var{filter_graph} is a description of the filter graph to apply to
81 the stream, and must have a single video input and a single video
82 output. In the filter graph, the input is associated to the label
83 @code{in}, and the output to the label @code{out}. See the
84 ffmpeg-filters manual for more information about the filtergraph
87 @item -i @var{input_file}
88 Read @var{input_file}.
91 @section Advanced options
93 @item -pix_fmt @var{format}
95 This option has been deprecated in favor of private options, try -pixel_format.
97 Show the stream duration, the codec parameters, the current position in
98 the stream and the audio/video synchronisation drift.
102 Non-spec-compliant optimizations.
106 Force RTP/TCP protocol usage instead of RTP/UDP. It is only meaningful
107 if you are streaming with the RTSP protocol.
108 @item -sync @var{type}
109 Set the master clock to audio (@code{type=audio}), video
110 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
111 master clock is used to control audio-video synchronization. Most media
112 players use audio as master clock, but in some cases (streaming or high
113 quality broadcast) it is necessary to change that. This option is mainly
114 used for debugging purposes.
115 @item -threads @var{count}
116 Set the thread count.
117 @item -ast @var{audio_stream_number}
118 Select the desired audio stream number, counting from 0. The number
119 refers to the list of all the input audio streams. If it is greater
120 than the number of audio streams minus one, then the last one is
121 selected, if it is negative the audio playback is disabled.
122 @item -vst @var{video_stream_number}
123 Select the desired video stream number, counting from 0. The number
124 refers to the list of all the input video streams. If it is greater
125 than the number of video streams minus one, then the last one is
126 selected, if it is negative the video playback is disabled.
127 @item -sst @var{subtitle_stream_number}
128 Select the desired subtitle stream number, counting from 0. The number
129 refers to the list of all the input subtitle streams. If it is greater
130 than the number of subtitle streams minus one, then the last one is
131 selected, if it is negative the subtitle rendering is disabled.
133 Exit when video is done playing.
135 Exit if any key is pressed.
136 @item -exitonmousedown
137 Exit if any mouse button is pressed.
139 @item -codec:@var{media_specifier} @var{codec_name}
140 Force a specific decoder implementation for the stream identified by
141 @var{media_specifier}, which can assume the values @code{a} (audio),
142 @code{v} (video), and @code{s} subtitle.
144 @item -acodec @var{codec_name}
145 Force a specific audio decoder.
147 @item -vcodec @var{codec_name}
148 Force a specific video decoder.
150 @item -scodec @var{codec_name}
151 Force a specific subtitle decoder.
154 @section While playing
173 Cycle subtitle channel.
179 Seek backward/forward 10 seconds.
182 Seek backward/forward 1 minute.
184 @item page down/page up
185 Seek backward/forward 10 minutes.
188 Seek to percentage in file corresponding to fraction of width.
