It is mostly used as a testbed for the various FFmpeg APIs. @c man end @chapter Options @c man begin OPTIONS @include fftools-common-opts.texi @section Main options @table @option @item -x @var{width} Force displayed width. @item -y @var{height} Force displayed height. @item -s @var{size} Set frame size (WxH or abbreviation), needed for videos which do not contain a header with the frame size like raw YUV. This option has been deprecated in favor of private options, try -video_size. @item -fs Start in fullscreen mode. @item -an Disable audio. @item -vn Disable video. @item -sn Disable subtitles. @item -ss @var{pos} Seek to @var{pos}. Note that in most formats it is not possible to seek exactly, so @command{ffplay} will seek to the nearest seek point to @var{pos}. @var{pos} must be a time duration specification, see @ref{time duration syntax,,the Time duration section in the ffmpeg-utils(1) manual,ffmpeg-utils}. @item -t @var{duration} Play @var{duration} seconds of audio/video. @var{duration} must be a time duration specification, see @ref{time duration syntax,,the Time duration section in the ffmpeg-utils(1) manual,ffmpeg-utils}. @item -bytes Seek by bytes. @item -seek_interval Set custom interval, in seconds, for seeking using left/right keys. Default is 10 seconds. @item -nodisp Disable graphical display. @item -noborder Borderless window. @item -alwaysontop Window always on top. Available on: X11 with SDL >= 2.0.5, Windows SDL >= 2.0.6. @item -volume Set the startup volume. 0 means silence, 100 means no volume reduction or amplification. Negative values are treated as 0, values above 100 are treated as 100. @item -f @var{fmt} Force format. @item -window_title @var{title} Set window title (default is the input filename). @item -left @var{title} Set the x position for the left of the window (default is a centered window). @item -top @var{title} Set the y position for the top of the window (default is a centered window). @item -loop @var{number} Loops movie playback <number> times. 0 means forever. @item -showmode @var{mode} Set the show mode to use. Available values for @var{mode} are: @table @samp @item 0, video show video @item 1, waves show audio waves @item 2, rdft show audio frequency band using RDFT ((Inverse) Real Discrete Fourier Transform) @end table Default value is "video", if video is not present or cannot be played "rdft" is automatically selected. You can interactively cycle through the available show modes by pressing the key @key{w}. @item -vf @var{filtergraph} Create the filtergraph specified by @var{filtergraph} and use it to filter the video stream. @var{filtergraph} is a description of the filtergraph to apply to the stream, and must have a single video input and a single video output. In the filtergraph, the input is associated to the label @code{in}, and the output to the label @code{out}. See the ffmpeg-filters manual for more information about the filtergraph syntax. You can specify this parameter multiple times and cycle through the specified filtergraphs along with the show modes by pressing the key @key{w}. @item -af @var{filtergraph} @var{filtergraph} is a description of the filtergraph to apply to the input audio. Use the option "-filters" to show all the available filters (including sources and sinks). @item -i @var{input_url} Read @var{input_url}. @end table @section Advanced options @table @option @item -pix_fmt @var{format} Set pixel format. This option has been deprecated in favor of private options, try -pixel_format. @item -stats Print several playback statistics, in particular show the stream duration, the codec parameters, the current position in the stream and the audio/video synchronisation drift. It is shown by default, unless the log level is lower than @code{info}. Its display can be forced by manually specifying this option. To disable it, you need to specify @code{-nostats}. @item -fast Non-spec-compliant optimizations. @item -genpts Generate pts. @item -sync @var{type} Set the master clock to audio (@code{type=audio}), video (@code{type=video}) or external (@code{type=ext}). Default is audio. The master clock is used to control audio-video synchronization. Most media players use audio as master clock, but in some cases (streaming or high quality broadcast) it is necessary to change that. This option is mainly used for debugging purposes. @item -ast @var{audio_stream_specifier} Select the desired audio stream using the given stream specifier. The stream specifiers are described in the @ref{Stream specifiers} chapter. If this option is not specified, the "best" audio stream is selected in the program of the already selected video stream. @item -vst @var{video_stream_specifier} Select the desired video stream using the given stream specifier. The stream specifiers are described in the @ref{Stream specifiers} chapter. If this option is not specified, the "best" video stream is selected. @item -sst @var{subtitle_stream_specifier} Select the desired subtitle stream using the given stream specifier. The stream specifiers are described in the @ref{Stream specifiers} chapter. If this option is not specified, the "best" subtitle stream is selected in the program of the already selected video or audio stream. @item -autoexit Exit when video is done playing. @item -exitonkeydown Exit if any key is pressed. @item -exitonmousedown Exit if any mouse button is pressed. @item -codec:@var{media_specifier} @var{codec_name} Force a specific decoder implementation for the stream identified by @var{media_specifier}, which can assume the values @code{a} (audio), @code{v} (video), and @code{s} subtitle. @item -acodec @var{codec_name} Force a specific audio decoder. @item -vcodec @var{codec_name} Force a specific video decoder. @item -scodec @var{codec_name} Force a specific subtitle decoder. @item -autorotate Automatically rotate the video according to file metadata. Enabled by default, use @option{-noautorotate} to disable it. @item -framedrop Drop video frames if video is out of sync. Enabled by default if the master clock is not set to video. Use this option to enable frame dropping for all master clock sources, use @option{-noframedrop} to disable it. @item -infbuf Do not limit the input buffer size, read as much data as possible from the input as soon as possible. Enabled by default for realtime streams, where data may be dropped if not read in time. Use this option to enable infinite buffers for all inputs, use @option{-noinfbuf} to disable it. @item -filter_threads @var{nb_threads} Defines how many threads are used to process a filter pipeline. Each pipeline will produce a thread pool with this many threads available for parallel processing. The default is 0 which means that the thread count will be determined by the number of available CPUs. @end table @section While playing @table @key @item q, ESC Quit. @item f Toggle full screen. @item p, SPC Pause. @item m Toggle mute. @item 9, 0 Decrease and increase volume respectively. @item /, * Decrease and increase volume respectively. @item a Cycle audio channel in the current program. @item v Cycle video channel. @item t Cycle subtitle channel in the current program. @item c Cycle program. @item w Cycle video filters or show modes. @item s Step to the next frame. Pause if the stream is not already paused, step to the next video frame, and pause. @item left/right Seek backward/forward 10 seconds. @item down/up Seek backward/forward 1 minute. @item page down/page up Seek to the previous/next chapter. or if there are no chapters Seek backward/forward 10 minutes. @item right mouse click Seek to percentage in file corresponding to fraction of width. @item left mouse double-click Toggle full screen. @end table @c man end @include config.texi @ifset config-all @set config-readonly @ifset config-avutil @include utils.texi @end ifset @ifset config-avcodec @include codecs.texi @include bitstream_filters.texi @end ifset @ifset config-avformat @include formats.texi @include protocols.texi @end ifset @ifset config-avdevice @include devices.texi @end ifset @ifset config-swresample @include resampler.texi @end ifset @ifset config-swscale @include scaler.texi @end ifset @ifset config-avfilter @include filters.texi @end ifset @end ifset @chapter See Also @ifhtml @ifset config-all @url{ffplay.html,ffplay}, @end ifset @ifset config-not-all @url{ffplay-all.html,ffmpeg-all}, @end ifset @url{ffmpeg.html,ffmpeg}, @url{ffprobe.html,ffprobe}, @url{ffmpeg-utils.html,ffmpeg-utils}, @url{ffmpeg-scaler.html,ffmpeg-scaler}, @url{ffmpeg-resampler.html,ffmpeg-resampler}, @url{ffmpeg-codecs.html,ffmpeg-codecs}, @url{ffmpeg-bitstream-filters.html,ffmpeg-bitstream-filters}, @url{ffmpeg-formats.html,ffmpeg-formats}, @url{ffmpeg-devices.html,ffmpeg-devices}, @url{ffmpeg-protocols.html,ffmpeg-protocols}, @url{ffmpeg-filters.html,ffmpeg-filters} @end ifhtml @ifnothtml @ifset config-all ffplay(1), @end ifset @ifset config-not-all ffplay-all(1), @end ifset ffmpeg(1), ffprobe(1), ffmpeg-utils(1), ffmpeg-scaler(1), ffmpeg-resampler(1), ffmpeg-codecs(1), ffmpeg-bitstream-filters(1), ffmpeg-formats(1), ffmpeg-devices(1), ffmpeg-protocols(1), ffmpeg-filters(1) @end ifnothtml @include authors.texi @ignore @setfilename ffplay @settitle FFplay media player @end ignore @bye
