MF_E_VIDEO_REN_NO_PROCAMP_HW
MF_E_VIDEO_REN_NO_PROCAMP_HW is specific to video-renderer processing capabilities. The Enhanced Video Renderer mixer can perform color correction, but the exact video-processing functions exposed through IMFVideoProcessor depend on the graphics driver and DXVA processing support.
Query capability instead of assuming a slider is available
- Identify the active EVR mixer, presenter, adapter, driver, and media type.
- Obtain the video-processing interfaces through the EVR service path and query supported ProcAmp adjustments before setting brightness, contrast, hue, or saturation controls.
- Distinguish a missing hardware capability from an invalid numeric value for a supported control.
Recreating the Media Session does not add a capability that the active video processor lacks. An application should disable unsupported controls or select a different software/video-processing path when color adjustment is required independently of the hardware.
