This DDI is not callable by applications, and applications cannot replace the VMR's deinterlacing functionality. The mixer uses the DirectX Video Acceleration (DXVA) deinterlacing device driver interface (DDI) to perform the deinterlacing. In this case, although the VMR is reporting 30fps the video is actually being rendered at 60 flips per second.Įxcept in the case of the VMR-7 using hardware overlay, deinterlacing is performed by the VMR's mixer. On systems where the graphics hardware doesn't support advanced deinterlacing, the VMR-7 can fall back to the hardware overlay and instruct it to use a BOB style deinterlace. There is one important difference in interlacing behavior between the VMR-7 and the VMR-9. Deinterlacing is performed on a per-stream basis. The application can query for the hardware deinterlacing capabilities and set deinterlacing preferences through the IVMRDeinterlaceControl interface (VMR-7) or IVMRDeinterlaceControl9 interface (VMR-9). The exact features that are available depend on the underlying hardware. ![]() ![]() The Video Mixing Renderer (VMR) supports hardware-accelerated deinterlacing, which improves rendering quality for interlaced video.
