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.
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{filtergraph}
77 Create the filtergraph specified by @var{filtergraph} and use it to
78 filter the video stream.
80 @var{filtergraph} is a description of the filtergraph to apply to
81 the stream, and must have a single video input and a single video
82 output. In the filtergraph, 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 -af @var{filtergraph}
88 @var{filtergraph} is a description of the filtergraph to apply to
90 Use the option "-filters" to show all the available filters (including
93 @item -i @var{input_file}
94 Read @var{input_file}.
97 @section Advanced options
99 @item -pix_fmt @var{format}
101 This option has been deprecated in favor of private options, try -pixel_format.
104 Print several playback statistics, in particular show the stream
105 duration, the codec parameters, the current position in the stream and
106 the audio/video synchronisation drift. It is on by default, to
107 explicitly disable it you need to specify @code{-nostats}.
112 Non-spec-compliant optimizations.
116 Force RTP/TCP protocol usage instead of RTP/UDP. It is only meaningful
117 if you are streaming with the RTSP protocol.
118 @item -sync @var{type}
119 Set the master clock to audio (@code{type=audio}), video
120 (@code{type=video}) or external (@code{type=ext}). Default is audio. The
121 master clock is used to control audio-video synchronization. Most media
122 players use audio as master clock, but in some cases (streaming or high
123 quality broadcast) it is necessary to change that. This option is mainly
124 used for debugging purposes.
125 @item -threads @var{count}
126 Set the thread count.
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 @section While playing
177 Cycle audio channel in the curret program.
183 Cycle subtitle channel in the current program.
192 Seek backward/forward 10 seconds.
195 Seek backward/forward 1 minute.
197 @item page down/page up
198 Seek backward/forward 10 minutes.
201 Seek to percentage in file corresponding to fraction of width.
