CTransInPlaceFilter.Copy 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 Copy method copies a media sample.

Syntax

IMediaSample* Copy(
   IMediaSample *pSource
);

Parameters

pSource

Pointer to the IMediaSample interface of the sample.

Return value

Returns a pointer to the IMediaSample interface on the new sample.

Remarks

This method retrieves an empty buffer from the downstream allocator. It copies all of the sample properties from pSource into the new sample, along with the actual data in the sample. If the filter is using two allocators, it calls this method to copy data across buffers.
