When to implement
If you are writing a custom media source, it is optional to implement this interface. Implement this interface if you need to support either of the following scenarios:

- Your media source can allocate DXGI buffers.
The IMFMediaSourceEx interface inherits from IMFMediaSource. IMFMediaSourceEx also has these types of members:
The IMFMediaSourceEx interface has these methods.
Gets an attribute store for the media source.
Gets an attribute store for a stream on the media source.
Sets a pointer to the DXGI Device Manager on the media source.
Implementations of this interface can return E_NOTIMPL for any methods that are not required by the media source.
