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

@section Syntax
@example
@c man begin SYNOPSIS
ffplay [options] @file{input_file}
@c man end
@end example
@c man begin OPTIONS
@section Main options
@table @option
@item -h
show help
@item -x width
force displayed width
@item -y height
force displayed height
@item -s size
Set frame size (WxH or abbreviation), needed for videos which don't
contain a header with the framesize like raw YUV.
@item -an
disable audio
@item -vn
disable video
@item -ss pos
seek to a given position in seconds
@item -bytes
seek by bytes
@item -nodisp
disable graphical display
@item -f fmt
force format
@end table
@section Advanced options
@table @option
@item -pix_fmt 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 -debug
print specific debug info
@item -bug
work around bugs
@item -vismv
visualize motion vectors
@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 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 count
thread count
@end table
@section While playing
@table @key
@item q, ESC
quit
@item f
toggle full screen
@item p, SPC
pause
@item a
cycle audio channel
@item v

@item w

@item left/right
seek backward/forward 10 seconds
@item down/up
seek backward/forward 1 minute
@item mouse click
