CTransInPlaceInputPin::GetAllocatorRequirements

  • Article

Passes requests for allocator requirements downstream.

HRESULT GetAllocatorRequirements(
  ALLOCATOR_PROPERTIES* pProps 
);

Parameters

  • pProps
    ALLOCATOR_PROPERTIES structure containing the required size, count, and alignment of the allocator.

Return Values

Returns E_NOTIMPL if the filter's output pin is not connected. Otherwise, returns an HRESULT that indicates whether the allocator properties were successfully received. HRESULT can be one of the following standard constants, or other values not listed.

Value Description
E_FAIL Failure.
E_POINTER Null pointer argument.
E_INVALIDARG Invalid argument.
E_NOTIMPL Method is not supported.
S_OK or NOERROR Success.

Remarks

This member function overrides the CBaseInputPin::GetAllocatorRequirements member function and implements the IMemInputPin::GetAllocatorRequirements method. If the downstream input pin can supply allocator requirements, it does so.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
