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_number}
128 Select the desired audio stream number, counting from 0. The number
129 refers to the list of all the input audio streams. If it is greater
130 than the number of audio streams minus one, then the last one is
131 selected, if it is negative the audio playback is disabled.
132 @item -vst @var{video_stream_number}
133 Select the desired video stream number, counting from 0. The number
134 refers to the list of all the input video streams. If it is greater
135 than the number of video streams minus one, then the last one is
136 selected, if it is negative the video playback is disabled.
137 @item -sst @var{subtitle_stream_number}
138 Select the desired subtitle stream number, counting from 0. The number
139 refers to the list of all the input subtitle streams. If it is greater
140 than the number of subtitle streams minus one, then the last one is
141 selected, if it is negative the subtitle rendering is disabled.
143 Exit when video is done playing.
145 Exit if any key is pressed.
146 @item -exitonmousedown
147 Exit if any mouse button is pressed.
149 @item -codec:@var{media_specifier} @var{codec_name}
150 Force a specific decoder implementation for the stream identified by
151 @var{media_specifier}, which can assume the values @code{a} (audio),
152 @code{v} (video), and @code{s} subtitle.
154 @item -acodec @var{codec_name}
155 Force a specific audio decoder.
157 @item -vcodec @var{codec_name}
158 Force a specific video decoder.
160 @item -scodec @var{codec_name}
161 Force a specific subtitle decoder.
164 Automatically rotate the video according to presentation metadata. Enabled by
165 default, use @option{-noautorotate} to disable it.
168 Drop video frames if video is out of sync. Enabled by default if the master
169 clock is not set to video. Use this option to enable frame dropping for all
170 master clock sources, use @option{-noframedrop} to disable it.
173 Do not limit the input buffer size, read as much data as possible from the
174 input as soon as possible. Enabled by default for realtime streams, where data
175 may be dropped if not read in time. Use this option to enable infinite buffers
176 for all inputs, use @option{-noinfbuf} to disable it.
180 @section While playing
193 Cycle audio channel in the current program.
199 Cycle subtitle channel in the current program.
205 Cycle video filters or show modes.
208 Step to the next frame.
210 Pause if the stream is not already paused, step to the next video
214 Seek backward/forward 10 seconds.
217 Seek backward/forward 1 minute.
219 @item page down/page up
220 Seek to the previous/next chapter.
221 or if there are no chapters
222 Seek backward/forward 10 minutes.
225 Seek to percentage in file corresponding to fraction of width.
