|Microsoft DirectX 9.0|
A stream-control start command has taken effect.
Pointer to the IPin interface of the pin that stopped the stream.
User-defined DWORD value.
Filters send this event in response to the IAMStreamControl::StopAt method. This method specifies a reference time for a pin to stop streaming. When streaming does halt, the filter sends this event.
The pSender parameter specifies the pin that executes the stop command. Depending on the implementation, it might not be the pin that received the StopAt call.
The dwCookie parameter is specified by the application in the StopAt method. This parameter enables the application to track multiple calls to the method.
