MF_E_VIDEO_REN_NO_DEINTERLACE_HW
MF_E_VIDEO_REN_NO_DEINTERLACE_HW means the renderer cannot obtain hardware deinterlacing for the requested video path. The EVR mixer uses DXVA video-processing services for deinterlacing and mixing, so available modes depend on the device, driver, and negotiated format.
Preserve interlace and device capability information
- Log the input media type's interlace attributes, frame size, frame rate, and the selected graphics adapter.
- Record the deinterlace preference and capabilities exposed by the EVR mixer/video processor.
- Check whether a device change or fallback selected a video-processing path with fewer capabilities than the original device.
Marking interlaced content as progressive merely to suppress the error can produce combing artifacts and incorrect timing. When hardware deinterlacing is unavailable, choose a supported processing mode or explicitly insert a software-capable video processor rather than lying about the source format.
