@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 test bench for the
|
|
various APIs of FFmpeg.

this option is used to force a given image format
|
|

@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 doing stream 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.
