IMSVidStreamBufferSourceEvent3 Interface

This topic applies to Update Rollup 2 for Microsoft Windows XP Media Center Edition 2005.

The IMSVidStreamBufferSourceEvent3 interface is used to receive events from the MSVidStreamBufferSource object.

This interface is an outgoing connection-point interface. To receive events from a playback device, implement this interface and then call the IConnectionPoint::Advise method to establish a connection.

In addition to the methods inherited from IMSVidStreamBufferSourceEvent2, the IMSVidStreamBufferSourceEvent3 interface exposes the following methods.

Method Description
BroadcastEvent Called when the object receives a broadcast event through the IBroadcastEvent interface.
BroadcastEventEx Called when the object receives a broadcast event through the IBroadcastEventEx interface.
ContentPrimarilyAudio Called when the Stream Buffer Engine is processing primarily audio data.
COPPBlocked Called when the content is blocked because of the Certified Output Protection Protocol (COPP) status.
COPPUnblocked Called when the content is unblocked after a COPPBlocked event.
