 various FFmpeg APIs.

 @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 don't

 contain a header with the frame size like raw YUV.

 @item -an

 Disable audio.

 @item -vn

 Disable video.

 @item -ss @var{pos}

 Seek to a given position in seconds.

 @item -t @var{duration}
 play <duration> seconds of audio/video

 @item -bytes

 Seek by bytes.

 @item -nodisp

 Disable graphical display.

 @item -f @var{fmt}

 Force format.

 @item -window_title @var{title}
 Set window title (default is the input filename).

 @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{filter_graph}
 @var{filter_graph} is a description of the filter graph to apply to
 the input video.
 Use the option "-filters" to show all the available filters (including
 also sources and sinks).
 

 @item -i @var{input_file}
 Read @var{input_file}.

 @end table

 
 @section Advanced options
 @table @option

 @item -pix_fmt @var{format}

 Set pixel format.

 @item -stats

 Show the stream duration, the codec parameters, the current position in
 the stream and the audio/video synchronisation drift.

 @item -bug

 Work around bugs.

 @item -fast

 Non-spec-compliant optimizations.

 @item -genpts

 Generate pts.

 @item -rtp_tcp

 Force RTP/TCP protocol usage instead of RTP/UDP. It is only meaningful
 if you are streaming with the RTSP protocol.

 @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 -threads @var{count}

 Set the thread count.

 @item -ast @var{audio_stream_number}
 Select the desired audio stream number, counting from 0. The number
 refers to the list of all the input audio streams. If it is greater
 than the number of audio streams minus one, then the last one is
 selected, if it is negative the audio playback is disabled.
 @item -vst @var{video_stream_number}
 Select the desired video stream number, counting from 0. The number
 refers to the list of all the input video streams. If it is greater
 than the number of video streams minus one, then the last one is
 selected, if it is negative the video playback is disabled.
 @item -sst @var{subtitle_stream_number}
 Select the desired subtitle stream number, counting from 0. The number
 refers to the list of all the input subtitle streams. If it is greater
 than the number of subtitle streams minus one, then the last one is
 selected, if it is negative the subtitle rendering is disabled.

 @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.

 @end table

 @item left/right

 Seek backward/forward 10 seconds.

 
 @item down/up

 Seek backward/forward 1 minute.

 
 @item mouse click
