Interfaces

Title Description
IEVRFilterConfig Sets the number of input pins on the DirectShow Enhanced Video Renderer (EVR) filter.
IEVRFilterConfigEx Configures the DirectShow Enhanced Video Renderer (EVR) filter.
IEVRTrustedVideoPlugin Enables a plug-in component for the enhanced video renderer (EVR) to work with protected media.
IMFDesiredSample Enables the presenter for the enhanced video renderer (EVR) to request a specific frame from the video mixer.
IMFTopologyServiceLookup Enables a custom video mixer or video presenter to get interface pointers from the Enhanced Video Renderer (EVR).
IMFTopologyServiceLookupClient Initializes a video mixer or presenter.
IMFVideoDeviceID Returns the device identifier supported by a video renderer component.
IMFVideoDisplayControl Controls how the Enhanced Video Renderer (EVR) displays video.
IMFVideoMixerControl Controls how the Enhanced Video Renderer (EVR) mixes video substreams.
IMFVideoMixerControl2 Controls preferences for video deinterlacing.
IMFVideoPositionMapper Maps a position on an input video stream to the corresponding position on an output video stream.
IMFVideoPresenter Represents a video presenter. A video presenter is an object that receives video frames, typically from a video mixer, and presents them in some way, typically by rendering them to the display.
IMFVideoRenderer Sets a new mixer or presenter for the Enhanced Video Renderer (EVR).
