COutputQueue::ReceiveMultiple (Compact 2013)

3/26/2014

Passes a set of samples to send to the input pin.

Syntax

HRESULT ReceiveMultiple(
  IMediaSample** ppSamples,
  long nSamples,
  long* nSamplesProcessed 
);

Parameters

• ppSamples
  Pointer to the set of samples to be passed to the connected input pin.

• nSamples
  Number of samples pointed to by ppSamples.

• nSamplesProcessed
  Updated to be the number of samples processed.

Return Value

Returns an HRESULT value, which can include the following values, or others.

Value	Description
Other	An error occurred before or while processing sample; any further samples will be discarded and this value returned.
S_FALSE	End of stream detected before or while processing sample; any further samples will be discarded and this value returned.
S_OK	Queued successfully or passed to the connected input pin if there is no queue.

Remarks

If the sticky return code is not S_OK, the sample is not sent and the sticky return code is returned. (A sticky return code is one that persists even after operations that would normally change its value.)

The samples are all released (by means of Release) after processing, regardless of whether the processing was successful.

Requirements

Header	dshow.h, Streams.h
Library	ole32.lib, Ole32auth.lib, Strmbase.lib, Strmiids.lib, uuid.lib
