@item -rtp_tcp

Force RTP/TCP protocol usage instead of RTP/UDP. It is only meaningful

|
@item -sync @var{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.
