The QueueSample method queues a sample.
void QueueSample( IMediaSample *pSample );
Pointer to the sample's IMediaSample interface.
This method adds a sample to the tail of the queue. Hold the critical section before calling this method, and call it only when the object is using a thread to deliver samples. To determine if the object is using a thread, call the COutputQueue::IsQueued method.
This method can also be used to put control messages onto the queue. A control message is a defined constant (cast to a LONG_PTR type) that instructs the thread to perform some action. The COutputQueue class defines the control messages shown in the following table.
|EOS_PACKET||Deliver an end-of-stream notification.|
|NEW_SEGMENT||Deliver a new segment.|
|RESET_PACKET||Reset the state of the queue.|
|SEND_PACKET||Send a partial batch of samples.|
This is a protected method, which the COutputQueue class uses internally.
