  11. @chapter Description
  12. @c man begin DESCRIPTION
  13. FFplay is a very simple and portable media player using the FFmpeg
  14. libraries and the SDL library. It is mostly used as a testbed for the
  15. various FFmpeg APIs.

  17. @chapter Options
  18. @c man begin OPTIONS

  38. @item -ss @var{pos}
  39. Seek to @var{pos}. Note that in most formats it is not possible to seek
  40. exactly, so @command{ffplay} will seek to the nearest seek point to
  41. @var{pos}.
  42. @var{pos} must be a time duration specification,
  43. see @ref{time duration syntax,,the Time duration section in the ffmpeg-utils(1) manual,ffmpeg-utils}.
  44. @item -t @var{duration}
  45. Play @var{duration} seconds of audio/video.

  47. see @ref{time duration syntax,,the Time duration section in the ffmpeg-utils(1) manual,ffmpeg-utils}.
  48. @item -bytes
  49. Seek by bytes.
  50. @item -nodisp
  51. Disable graphical display.
  52. @item -f @var{fmt}
  53. Force format.
  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:
  61. @table @samp
  62. @item 0, video
  63. show video
  64. @item 1, waves
  65. show audio waves
  66. @item 2, rdft
  67. show audio frequency band using RDFT ((Inverse) Real Discrete Fourier Transform)
  68. @end table
  69. Default value is "video", if video is not present or cannot be played
  70. "rdft" is automatically selected.
  71. You can interactively cycle through the available show modes by
  72. pressing the key @key{w}.
  73. @item -vf @var{filtergraph}
  74. Create the filtergraph specified by @var{filtergraph} and use it to
  75. filter the video stream.
  76. @var{filtergraph} is a description of the filtergraph to apply to
  77. the stream, and must have a single video input and a single video
  78. output. In the filtergraph, the input is associated to the label
  79. @code{in}, and the output to the label @code{out}. See the
  80. ffmpeg-filters manual for more information about the filtergraph
  81. syntax.
  82. You can specify this parameter multiple times and cycle through the specified
  83. filtergraphs along with the show modes by pressing the key @key{w}.
  84. @item -af @var{filtergraph}
  85. @var{filtergraph} is a description of the filtergraph to apply to
  86. the input audio.
  87. Use the option "-filters" to show all the available filters (including
  88. sources and sinks).
  89. @item -i @var{input_url}
  90. Read @var{input_url}.
  91. @end table
  92. @section Advanced options
  93. @table @option
  94. @item -pix_fmt @var{format}
  95. Set pixel format.
  96. This option has been deprecated in favor of private options, try -pixel_format.
  97. @item -stats
  98. Print several playback statistics, in particular show the stream
  99. duration, the codec parameters, the current position in the stream and
  100. the audio/video synchronisation drift. It is on by default, to
  101. explicitly disable it you need to specify @code{-nostats}.
  102. @item -fast
  103. Non-spec-compliant optimizations.
  104. @item -genpts
  105. Generate pts.
  106. @item -sync @var{type}
  107. Set the master clock to audio (@code{type=audio}), video
  108. (@code{type=video}) or external (@code{type=ext}). Default is audio. The
  109. master clock is used to control audio-video synchronization. Most media
  110. players use audio as master clock, but in some cases (streaming or high
  111. quality broadcast) it is necessary to change that. This option is mainly
  112. used for debugging purposes.
  113. @item -ast @var{audio_stream_specifier}
  114. Select the desired audio stream using the given stream specifier. The stream
  115. specifiers are described in the @ref{Stream specifiers} chapter. If this option
  116. is not specified, the "best" audio stream is selected in the program of the
  117. already selected video stream.
  118. @item -vst @var{video_stream_specifier}
  119. Select the desired video stream using the given stream specifier. The stream
  120. specifiers are described in the @ref{Stream specifiers} chapter. If this option
  121. is not specified, the "best" video stream is selected.
  122. @item -sst @var{subtitle_stream_specifier}
  123. Select the desired subtitle stream using the given stream specifier. The stream
  124. specifiers are described in the @ref{Stream specifiers} chapter. If this option
  125. is not specified, the "best" subtitle stream is selected in the program of the
  126. already selected video or audio stream.
  127. @item -autoexit
  128. Exit when video is done playing.
  129. @item -exitonkeydown
  130. Exit if any key is pressed.
  131. @item -exitonmousedown
  132. Exit if any mouse button is pressed.
  133. @item -codec:@var{media_specifier} @var{codec_name}
  134. Force a specific decoder implementation for the stream identified by
  135. @var{media_specifier}, which can assume the values @code{a} (audio),
  136. @code{v} (video), and @code{s} subtitle.
  137. @item -acodec @var{codec_name}
  138. Force a specific audio decoder.
  139. @item -vcodec @var{codec_name}
  140. Force a specific video decoder.
  141. @item -scodec @var{codec_name}
  142. Force a specific subtitle decoder.
  143. @item -autorotate
  144. Automatically rotate the video according to file metadata. Enabled by
  145. default, use @option{-noautorotate} to disable it.
  146. @item -framedrop
  147. Drop video frames if video is out of sync. Enabled by default if the master
  148. clock is not set to video. Use this option to enable frame dropping for all
  149. master clock sources, use @option{-noframedrop} to disable it.
  150. @item -infbuf
  151. Do not limit the input buffer size, read as much data as possible from the
  152. input as soon as possible. Enabled by default for realtime streams, where data
  153. may be dropped if not read in time. Use this option to enable infinite buffers
  154. for all inputs, use @option{-noinfbuf} to disable it.
