Interfaces for Video Rendering and Overlay
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
These interfaces support application control over video rendering. Note that some of these interfaces are now deprecated, because the Video Mixing Renderer filter provides superior rendering and overlay control.
| Interface | Description |
|---|---|
| IAMLine21Decoder | Provides access to closed-captioned information and settings. |
| IAMOverlayFX | Apply overlay effects to the video surface. (Deprecated.) |
| IAMVideoDecimationProperties | Control how DirectShow scales a video image if the video window is smaller than the native size of the video. (Deprecated.) |

| IDirectDrawVideo | Disable specified DirectDraw capabilities. (Deprecated.) |
| IDirectDrawMediaSample | Access a DirectDraw surface allocated by the Overlay Mixer filter.(Deprecated.) |
| IMixerOCX | Implemented on the Overlay Mixer. Enables windowless clients such as ActiveX® controls to get and set properties of the video rectangle and advise the filter of events. |
| IMixerOCXNotify | Implemented by windowless clients and called by the Overlay Mixer to send notifications of events affecting the video display rectangle. |
| IMixerPinConfig2 | Set video color controls on the Overlay Mixer filter when mixing multiple video streams. (Deprecated.) |
| IQualProp | Query a video renderer for performance information. |
