IMSVidVideoRenderer2::SetAllocator method (segment.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
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 *AllocPresent,
[in] long ID
);
Parameters
[in] AllocPresent
Pointer to the IUnknown interface of the allocator-presenter object.
[in] ID
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.
