CBaseOutputPin.InitAllocator 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 InitAllocator method creates a memory allocator.

Syntax

virtual HRESULT InitAllocator(
   IMemAllocator **ppAlloc
);

Parameters

ppAlloc

Address of a variable that receives a pointer to the allocator's IMemAllocator interface.

Return value

Returns S_OK if successful, or an error code from the CoCreateInstance function.

Remarks

If the input pin does not provide a memory allocator, the CBaseOutputPin::DecideAllocator method calls this method to create an allocator.
