evr.h header
[The component described on this page, Enhanced Video Renderer, is a legacy feature. It has been superseded by the Simple Video Renderer (SVR) exposed through the MediaPlayer and IMFMediaEngine components. To play video content you should send data into one of these components and allow them to instantiate the new video renderer. These components have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer or the lower level IMFMediaEngine APIs to play video media in Windows instead of the EVR, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

evr.h contains the following programming interfaces:
Interfaces
| 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). |
Callback functions
| MFCreateVideoMixer Creates the default video mixer for the enhanced video renderer (EVR). |
| MFCreateVideoMixerAndPresenter Creates the default video mixer and video presenter for the enhanced video renderer (EVR). |
| MFCreateVideoPresenter Creates the default video presenter for the enhanced video renderer (EVR). |
| MFCreateVideoRenderer Creates an instance of the enhanced video renderer (EVR) media sink. |
| MFCreateVideoSampleAllocator Creates an object that allocates video samples. |
| MFCreateVideoSampleFromSurface Creates a media sample that manages a Direct3D surface. |
Structures
| MFVideoNormalizedRect The MFVideoNormalizedRect (evr.h) structure defines a normalized rectangle, which is used to specify sub-rectangles in a video rectangle. |
Enumerations
| EVRFilterConfigPrefs Contains flags that are used to configure the Microsoft DirectShow enhanced video renderer (EVR) filter. |
| MFVideoAspectRatioMode Specifies the aspect-ratio mode. |
| MFVideoMixPrefs Contains flags that are used to configure how the enhanced video renderer (EVR) performs deinterlacing. |
| MFVideoRenderPrefs Contains flags that define how the enhanced video renderer (EVR) displays the video. |
| MFVP_MESSAGE_TYPE Defines messages for an enhanced video renderer (EVR) presenter. |
