function OnSourceChanged (
    pEventSource : IUccMediaChannel, 
    pEventData : UccAudioVideoMediaChannelSourceEvent
)

Parameters

  • pEventSource
    A value of the IUccMediaChannel* (IUccMediaChannel, for a .NET application) type. This identifies the audio or video channel raising this event.

Remarks

For an audio channel the source is the dominant speaker. For a video channel this event means a video contributor changed.

Win32 COM/C++ Syntax

HRESULT OnSourceChanged
(
   IUccMediaChannel* pEventSource,
   IUccAudioVideoMediaChannelSourceEvent* pEventData
);

Note

In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Trace and Handle Errors in Unified Communications Client API.

All public static (Shared in Visual Basic) members of this type are thread-safe. Instance members are not guaranteed to be thread-safe.
