IAMVideoAcceleratorNotify interface (videoacc.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IAMVideoAcceleratorNotify interface is a callback interface used in conjunction with the IAMVideoAccelerator interface. It enables the video renderer filter to communicate with the video decoder when configuring
DirectX Video Acceleration (DXVA) decoding.
Inheritance
