bool Rtsp::Stream::GoToLive ( )

overridevirtual

Set the stream to Live and call Play.

Implements MediaController::IStream.

Definition at line 78 of file RtspStream.cpp.

78 { return true; }

void Rtsp::Stream::NewRequest ( MediaRequest & request )

overridevirtual

Set the stream to a new source.

Parameters

request The new MediaRequest to reset the stream to.

Implements MediaController::IStream.

Definition at line 90 of file RtspStream.cpp.

                                                  {

void Rtsp::Stream::Pause ( )

overridevirtual

Call Pause on the stream.

Implements MediaController::IStream.

Definition at line 62 of file RtspStream.cpp.

bool Rtsp::Stream::Play	(	float	speed = `0`,

	)

overridevirtual

Call Play on the stream.

Parameters

speed	The playback speed. Negative values can be used for reverse playback. A value of 0 will resume a paused stream.
unixTime	The start time for playback. A value of 0 will start a live stream.

Implements MediaController::IStream.
