Tells the remote side to select the desired video source using the mode specified. Does nothing if either video source or mode aren't available

void OpalH281Client::SendExtraCapabilities ( ) const

virtual

Causes the H.281 handler to send its capabilities. Capabilities include the number of available cameras, (default one) the camera abilities (default none) and the number of presets that can be stored (default zero)

Reimplemented from OpalH224Client.

void OpalH281Client::SendStopAction ( )

protected

void OpalH281Client::SetCapabilityChangedNotifier ( const PNotifier & notifier )
