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 Set the startup volume. 0 means silence, 100 means no volume reduction or
71 amplification. Negative values are treated as 0, values above 100 are treated
75 @item -window_title @var{title}
76 Set window title (default is the input filename).
77 @item -left @var{title}
78 Set the x position for the left of the window (default is a centered window).
79 @item -top @var{title}
80 Set the y position for the top of the window (default is a centered window).
81 @item -loop @var{number}
82 Loops movie playback <number> times. 0 means forever.
83 @item -showmode @var{mode}
84 Set the show mode to use.
85 Available values for @var{mode} are:
92 show audio frequency band using RDFT ((Inverse) Real Discrete Fourier Transform)
95 Default value is "video", if video is not present or cannot be played
96 "rdft" is automatically selected.
98 You can interactively cycle through the available show modes by
99 pressing the key @key{w}.
101 @item -vf @var{filtergraph}
102 Create the filtergraph specified by @var{filtergraph} and use it to
103 filter the video stream.
105 @var{filtergraph} is a description of the filtergraph to apply to
106 the stream, and must have a single video input and a single video
107 output. In the filtergraph, the input is associated to the label
108 @code{in}, and the output to the label @code{out}. See the
109 ffmpeg-filters manual for more information about the filtergraph
112 You can specify this parameter multiple times and cycle through the specified
113 filtergraphs along with the show modes by pressing the key @key{w}.
115 @item -af @var{filtergraph}
116 @var{filtergraph} is a description of the filtergraph to apply to
118 Use the option "-filters" to show all the available filters (including
121 @item -i @var{input_url}
122 Read @var{input_url}.
125 @section Advanced options
127 @item -pix_fmt @var{format}
129 This option has been deprecated in favor of private options, try -pixel_format.
132 Print several playback statistics, in particular show the stream
133 duration, the codec parameters, the current position in the stream and
134 the audio/video synchronisation drift. It is on by default, to
135 explicitly disable it you need to specify @code{-nostats}.
138 Non-spec-compliant optimizations.
141 @item -sync @var{type}
142 Set the master clock to audio (@code{type=audio}), video
143 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
144 master clock is used to control audio-video synchronization. Most media
145 players use audio as master clock, but in some cases (streaming or high
146 quality broadcast) it is necessary to change that. This option is mainly
147 used for debugging purposes.
148 @item -ast @var{audio_stream_specifier}
149 Select the desired audio stream using the given stream specifier. The stream
150 specifiers are described in the @ref{Stream specifiers} chapter. If this option
151 is not specified, the "best" audio stream is selected in the program of the
152 already selected video stream.
153 @item -vst @var{video_stream_specifier}
154 Select the desired video stream using the given stream specifier. The stream
155 specifiers are described in the @ref{Stream specifiers} chapter. If this option
156 is not specified, the "best" video stream is selected.
157 @item -sst @var{subtitle_stream_specifier}
158 Select the desired subtitle stream using the given stream specifier. The stream
159 specifiers are described in the @ref{Stream specifiers} chapter. If this option
160 is not specified, the "best" subtitle stream is selected in the program of the
161 already selected video or audio stream.
163 Exit when video is done playing.
165 Exit if any key is pressed.
166 @item -exitonmousedown
167 Exit if any mouse button is pressed.
169 @item -codec:@var{media_specifier} @var{codec_name}
170 Force a specific decoder implementation for the stream identified by
171 @var{media_specifier}, which can assume the values @code{a} (audio),
172 @code{v} (video), and @code{s} subtitle.
174 @item -acodec @var{codec_name}
175 Force a specific audio decoder.
177 @item -vcodec @var{codec_name}
178 Force a specific video decoder.
180 @item -scodec @var{codec_name}
181 Force a specific subtitle decoder.
184 Automatically rotate the video according to file metadata. Enabled by
185 default, use @option{-noautorotate} to disable it.
188 Drop video frames if video is out of sync. Enabled by default if the master
189 clock is not set to video. Use this option to enable frame dropping for all
190 master clock sources, use @option{-noframedrop} to disable it.
193 Do not limit the input buffer size, read as much data as possible from the
194 input as soon as possible. Enabled by default for realtime streams, where data
195 may be dropped if not read in time. Use this option to enable infinite buffers
196 for all inputs, use @option{-noinfbuf} to disable it.
198 @item -filter_threads @var{nb_threads}
199 Defines how many threads are used to process a filter pipeline. Each pipeline
200 will produce a thread pool with this many threads available for parallel
201 processing. The default is 0 which means that the thread count will be
202 determined by the number of available CPUs.

222 Decrease and increase volume respectively.
225 Decrease and increase volume respectively.
228 Cycle audio channel in the current program.
234 Cycle subtitle channel in the current program.
240 Cycle video filters or show modes.
243 Step to the next frame.
245 Pause if the stream is not already paused, step to the next video
249 Seek backward/forward 10 seconds.
252 Seek backward/forward 1 minute.
