IMSVidVideoRenderer2::SetAllocator Method

This topic applies to Windows XP Service Pack 1 or later.
The SetAllocator method specifies an allocator-presenter for the VMR. Applications can use this method to provide their own custom allocator-presenter objects.

Syntax

HRESULT SetAllocator(
  [in]  IUnknown *pAllocPresent,
  [in]  long ID = -1
);

Parameters

• pAllocPresent [in]
  Pointer to the IUnknown interface of the allocator-presenter object.

• ID [in]
  Optionally, specifies an identifier (ID) for the allocator-presenter object. The default value of -1 indicates that the MSVidVideoRenderer object will create an ID when it builds the filter graph. In that case, the MSVidVideoRenderer object uses the lower 32 bits of the allocator-presenter's IUnknown interface pointer as the ID. Note that the ID is for application use; the VMR does not use it.

Return Value

Returns an HRESULT value. Possible values include the following.
