Enhanced Video Renderer Filter

This topic applies to Windows Vista and later.

The Enhanced Video Renderer (EVR) filter is a 16-channel video mixer and renderer. It has the same core functionality and plug-in model as the Media Foundation EVR media sink.

The DirectShow EVR filter is documented in the Media Foundation SDK documentation; for more information, see Enhanced Video Renderer.

Filter Interfaces (QueryInterface) DirectShow interfaces:

Media Foundation interfaces:

  • IEVRFilterConfig
  • IMFGetService
  • IMFVideoPositionMapper
  • IMFVideoRenderer

Remarks

In addition to the interfaces exposed through QueryInterface, the EVR exposes other interfaces through the IMFGetService::GetService method. Some of these interfaces are implemented by the EVR presenter or the EVR mixer, rather than the EVR itself. If the application sets a custom presenter or mixer on the EVR, the custom versions might expose a different set of interfaces.
