Remarks

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 is a proxy to a hardware device.
• Your media source can allocate DXGI buffers.

Implementations of this interface can return E_NOTIMPL for any methods that are not required by the media source.
