@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 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. |
