IVMRImageCompositor9::InitCompositionDevice method (vmr9.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The InitCompositionDevice method informs the compositor that a new composition target has been created. The compositor should perform any necessary configuration work in this method. This could include attaching a Z or stencil buffer for the new render target.
