@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 Main options 
 
@table @option 
@item -h 
show help 
@item -x width

@item -y height 
force displayed height

when playing image sequences. Example:

@end example 
@end table 
 
@section Advanced options 
@table @option 
@item -stats 
Show the stream duration, the codec parameters, the current position in 
the stream and the audio/video synchronisation drift. 
@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.
