COutputQueue.ReceiveMultiple method

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 delivers a batch of media samples to the input pin.

Syntax

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

Parameters

ppSamples

Address of a pointer to an array of samples.

nSamples

Number of samples in the array.

nSamplesProcessed

Pointer to a variable that receives the number of samples delivered successfully.

Return code Description
