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 fftools-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.
41 Start in fullscreen mode.
49 Seek to a given position in seconds.
50 @item -t @var{duration}
51 play <duration> seconds of audio/video
55 Disable graphical display.
58 @item -window_title @var{title}
59 Set window title (default is the input filename).
60 @item -loop @var{number}
61 Loops movie playback <number> times. 0 means forever.
62 @item -showmode @var{mode}
63 Set the show mode to use.
64 Available values for @var{mode} are:
71 show audio frequency band using RDFT ((Inverse) Real Discrete Fourier Transform)
74 Default value is "video", if video is not present or cannot be played
75 "rdft" is automatically selected.
77 You can interactively cycle through the available show modes by
78 pressing the key @key{w}.
80 @item -vf @var{filtergraph}
81 Create the filtergraph specified by @var{filtergraph} and use it to
82 filter the video stream.
84 @var{filtergraph} is a description of the filtergraph to apply to
85 the stream, and must have a single video input and a single video
86 output. In the filtergraph, the input is associated to the label
87 @code{in}, and the output to the label @code{out}. See the
88 ffmpeg-filters manual for more information about the filtergraph
91 You can specify this parameter multiple times and cycle through the specified
92 filtergraphs along with the show modes by pressing the key @key{w}.
94 @item -af @var{filtergraph}
95 @var{filtergraph} is a description of the filtergraph to apply to
97 Use the option "-filters" to show all the available filters (including
100 @item -i @var{input_file}
101 Read @var{input_file}.
104 @section Advanced options
106 @item -pix_fmt @var{format}
108 This option has been deprecated in favor of private options, try -pixel_format.
111 Print several playback statistics, in particular show the stream
112 duration, the codec parameters, the current position in the stream and
113 the audio/video synchronisation drift. It is on by default, to
114 explicitly disable it you need to specify @code{-nostats}.
117 Non-spec-compliant optimizations.
120 @item -sync @var{type}
121 Set the master clock to audio (@code{type=audio}), video
122 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
123 master clock is used to control audio-video synchronization. Most media
124 players use audio as master clock, but in some cases (streaming or high
125 quality broadcast) it is necessary to change that. This option is mainly
126 used for debugging purposes.
127 @item -ast @var{audio_stream_specifier}
128 Select the desired audio stream using the given stream specifier. The stream
129 specifiers are described in the @ref{Stream specifiers} chapter. If this option
130 is not specified, the "best" audio stream is selected in the program of the
131 already selected video stream.
132 @item -vst @var{video_stream_specifier}
133 Select the desired video stream using the given stream specifier. The stream
134 specifiers are described in the @ref{Stream specifiers} chapter. If this option
135 is not specified, the "best" video stream is selected.
136 @item -sst @var{subtitle_stream_specifier}
137 Select the desired subtitle stream using the given stream specifier. The stream
138 specifiers are described in the @ref{Stream specifiers} chapter. If this option
139 is not specified, the "best" subtitle stream is selected in the program of the
140 already selected video or audio stream.
142 Exit when video is done playing.
144 Exit if any key is pressed.
145 @item -exitonmousedown
146 Exit if any mouse button is pressed.
148 @item -codec:@var{media_specifier} @var{codec_name}
149 Force a specific decoder implementation for the stream identified by
150 @var{media_specifier}, which can assume the values @code{a} (audio),
151 @code{v} (video), and @code{s} subtitle.
153 @item -acodec @var{codec_name}
154 Force a specific audio decoder.
156 @item -vcodec @var{codec_name}
157 Force a specific video decoder.
159 @item -scodec @var{codec_name}
160 Force a specific subtitle decoder.
163 Automatically rotate the video according to presentation metadata. Enabled by
164 default, use @option{-noautorotate} to disable it.
167 Drop video frames if video is out of sync. Enabled by default if the master
168 clock is not set to video. Use this option to enable frame dropping for all
169 master clock sources, use @option{-noframedrop} to disable it.
172 Do not limit the input buffer size, read as much data as possible from the
173 input as soon as possible. Enabled by default for realtime streams, where data
174 may be dropped if not read in time. Use this option to enable infinite buffers
175 for all inputs, use @option{-noinfbuf} to disable it.
179 @section While playing
192 Cycle audio channel in the current program.
198 Cycle subtitle channel in the current program.
204 Cycle video filters or show modes.
207 Step to the next frame.
209 Pause if the stream is not already paused, step to the next video
213 Seek backward/forward 10 seconds.
216 Seek backward/forward 1 minute.
218 @item page down/page up
219 Seek to the previous/next chapter.
220 or if there are no chapters
221 Seek backward/forward 10 minutes.
224 Seek to percentage in file corresponding to fraction of width.
