The IDirectDrawMediaSampleAllocator interface is implemented on the allocator created by the Overlay Mixer for its upstream connection with a video decoder. This allocator allocates IDirectDrawMediaSample media samples that also support the IMediaSample interface.
Decoder filters should not have to use this interface to connect to the Overlay Mixer. Applications never use this interface.
In addition to the methods inherited from IUnknown, the IDirectDrawMediaSampleAllocator interface exposes the following method.
|GetDirectDraw||Retrieves the DirectDraw instance used to allocate surfaces.|
