139.IX Header "DESCRIPTION"
140FFplay is a very simple and portable media player using the FFmpeg
141libraries and the \s-1SDL\s0 library. It is mostly used as a testbed for the
142various FFmpeg APIs.

184Force \s-1RTP/TCP\s0 protocol usage instead of \s-1RTP/UDP\s0. It is only meaningful

189(\f(CW\*(C`type=video\*(C'\fR) or external (\f(CW\*(C`type=ext\*(C'\fR). Default is audio. The
190master clock is used to control audio-video synchronization. Most media
191players use audio as master clock, but in some cases (streaming or high
192quality broadcast) it is necessary to change that. This option is mainly
193used for debugging purposes.
