.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
FFplay is a very simple and portable media player using the FFmpeg
libraries and the \s-1SDL\s0 library. It is mostly used as a testbed for the
various FFmpeg APIs.

the stream and the audio/video synchronisation drift.
.IP "\fB\-rtp_tcp\fR" 4
.IX Item "-rtp_tcp"
Force \s-1RTP/TCP\s0 protocol usage instead of \s-1RTP/UDP\s0. It is only meaningful
if you are streaming with the \s-1RTSP\s0 protocol.
.IP "\fB\-sync type\fR" 4
.IX Item "-sync type"
Set the master clock to audio (\f(CW\*(C`type=audio\*(C'\fR), video
(\f(CW\*(C`type=video\*(C'\fR) or external (\f(CW\*(C`type=ext\*(C'\fR). 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.
