18 @c man begin DESCRIPTION
20 FFplay is a very simple and portable media player using the FFmpeg
21 libraries and the SDL library. It is mostly used as a testbed for the
28 @include fftools-common-opts.texi
34 Force displayed width.
36 Force displayed height.
38 Set frame size (WxH or abbreviation), needed for videos which do
39 not contain a header with the frame size like raw YUV. This option
40 has been deprecated in favor of private options, try -video_size.
42 Start in fullscreen mode.
50 Seek to @var{pos}. Note that in most formats it is not possible to seek
51 exactly, so @command{ffplay} will seek to the nearest seek point to
54 @var{pos} must be a time duration specification,
55 see @ref{time duration syntax,,the Time duration section in the ffmpeg-utils(1) manual,ffmpeg-utils}.
56 @item -t @var{duration}
57 Play @var{duration} seconds of audio/video.
59 @var{duration} must be a time duration specification,
60 see @ref{time duration syntax,,the Time duration section in the ffmpeg-utils(1) manual,ffmpeg-utils}.
64 Set custom interval, in seconds, for seeking using left/right keys. Default is 10 seconds.
66 Disable graphical display.
70 Window always on top. Available on: X11 with SDL >= 2.0.5, Windows SDL >= 2.0.6.
72 Set the startup volume. 0 means silence, 100 means no volume reduction or
73 amplification. Negative values are treated as 0, values above 100 are treated
77 @item -window_title @var{title}
78 Set window title (default is the input filename).
79 @item -left @var{title}
80 Set the x position for the left of the window (default is a centered window).
81 @item -top @var{title}
82 Set the y position for the top of the window (default is a centered window).
83 @item -loop @var{number}
84 Loops movie playback <number> times. 0 means forever.
85 @item -showmode @var{mode}
86 Set the show mode to use.
87 Available values for @var{mode} are:
94 show audio frequency band using RDFT ((Inverse) Real Discrete Fourier Transform)
97 Default value is "video", if video is not present or cannot be played
98 "rdft" is automatically selected.
100 You can interactively cycle through the available show modes by
101 pressing the key @key{w}.
103 @item -vf @var{filtergraph}
104 Create the filtergraph specified by @var{filtergraph} and use it to
105 filter the video stream.
107 @var{filtergraph} is a description of the filtergraph to apply to
108 the stream, and must have a single video input and a single video
109 output. In the filtergraph, the input is associated to the label
110 @code{in}, and the output to the label @code{out}. See the
111 ffmpeg-filters manual for more information about the filtergraph
114 You can specify this parameter multiple times and cycle through the specified
115 filtergraphs along with the show modes by pressing the key @key{w}.
117 @item -af @var{filtergraph}
118 @var{filtergraph} is a description of the filtergraph to apply to
120 Use the option "-filters" to show all the available filters (including
123 @item -i @var{input_url}
124 Read @var{input_url}.
127 @section Advanced options
129 @item -pix_fmt @var{format}
131 This option has been deprecated in favor of private options, try -pixel_format.
134 Print several playback statistics, in particular show the stream
135 duration, the codec parameters, the current position in the stream and
136 the audio/video synchronisation drift. It is shown by default, unless the
137 log level is lower than @code{info}. Its display can be forced by manually
138 specifying this option. To disable it, you need to specify @code{-nostats}.
141 Non-spec-compliant optimizations.
144 @item -sync @var{type}
145 Set the master clock to audio (@code{type=audio}), video
146 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
147 master clock is used to control audio-video synchronization. Most media
148 players use audio as master clock, but in some cases (streaming or high
149 quality broadcast) it is necessary to change that. This option is mainly
150 used for debugging purposes.
151 @item -ast @var{audio_stream_specifier}
152 Select the desired audio stream using the given stream specifier. The stream
153 specifiers are described in the @ref{Stream specifiers} chapter. If this option
154 is not specified, the "best" audio stream is selected in the program of the
155 already selected video stream.
156 @item -vst @var{video_stream_specifier}
157 Select the desired video stream using the given stream specifier. The stream
158 specifiers are described in the @ref{Stream specifiers} chapter. If this option
159 is not specified, the "best" video stream is selected.
160 @item -sst @var{subtitle_stream_specifier}
161 Select the desired subtitle stream using the given stream specifier. The stream
162 specifiers are described in the @ref{Stream specifiers} chapter. If this option
163 is not specified, the "best" subtitle stream is selected in the program of the
164 already selected video or audio stream.
166 Exit when video is done playing.
168 Exit if any key is pressed.
169 @item -exitonmousedown
170 Exit if any mouse button is pressed.
172 @item -codec:@var{media_specifier} @var{codec_name}
173 Force a specific decoder implementation for the stream identified by
174 @var{media_specifier}, which can assume the values @code{a} (audio),
175 @code{v} (video), and @code{s} subtitle.
177 @item -acodec @var{codec_name}
178 Force a specific audio decoder.
180 @item -vcodec @var{codec_name}
181 Force a specific video decoder.
183 @item -scodec @var{codec_name}
184 Force a specific subtitle decoder.
187 Automatically rotate the video according to file metadata. Enabled by
188 default, use @option{-noautorotate} to disable it.
191 Drop video frames if video is out of sync. Enabled by default if the master
192 clock is not set to video. Use this option to enable frame dropping for all
193 master clock sources, use @option{-noframedrop} to disable it.
196 Do not limit the input buffer size, read as much data as possible from the
197 input as soon as possible. Enabled by default for realtime streams, where data
198 may be dropped if not read in time. Use this option to enable infinite buffers
199 for all inputs, use @option{-noinfbuf} to disable it.
201 @item -filter_threads @var{nb_threads}
202 Defines how many threads are used to process a filter pipeline. Each pipeline
203 will produce a thread pool with this many threads available for parallel
204 processing. The default is 0 which means that the thread count will be
205 determined by the number of available CPUs.
