CBaseInputPin.ReceiveMultiple method

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The ReceiveMultiple method receives an array of samples. This method implements the IMemInputPin::ReceiveMultiple method.

Syntax

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

Parameters

pSamples

Address of an array of IMediaSample pointers, of size nSamples.

nSamples

Number of samples to process.

nSamplesProcessed

Pointer to a variable that receives the number of samples that were processed.

Return value

Returns an HRESULT value. Possible values include those listed in the following table.

Remarks

This method behaves like the CBaseInputPin::Receive method, but receives an array of samples. In the base class, the method loops through the array and calls Receive with each sample. Override this function if your filter can process batches of samples more efficiently than processing them one at a time.
