CBaseInputPin.GetAllocatorRequirements 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 GetAllocatorRequirements
method retrieves the allocator properties requested by the input pin.
Syntax
HRESULT GetAllocatorRequirements(
ALLOCATOR_PROPERTIES *pProps
);
Parameters
-
pProps
-
Pointer to an ALLOCATOR_PROPERTIES structure, which is filled in with the requirements.
Return value
Returns E_NOTIMPL.
Remarks
When an output pin initializes a memory allocator, it can call this method to determine whether the input pin has any buffer requirements. For more information, see CBaseOutputPin::DecideAllocator.
Implementing this method is optional. If the filter has specific alignment or prefix requirements, override this method.
