Full Screen Renderer Filter

The Full Screen Renderer filter provides full-screen video rendering on older hardware. Newer video cards can stretch the video efficiently enough that the Full Screen Renderer is not required. Therefore, the use of this filter is now deprecated.

Do not manually add this filter to the filter graph. If an application calls IVideoWindow::put_FullScreenMode, the Filter Graph Manager automatically selects the appropriate video renderer for full-screen mode. The selection is transparent to the application. With current video cards, the Filter Graph Manager is unlikely to select the Full Screen Renderer.

Remarks

The Full Screen Renderer supports a static set of display modes. The video card on the user's system might not support every mode, however. To determine whether the card supports a particular mode, call the IFullScreenVideoEx::IsModeAvailable method. You can also disable a particular display mode programmatically, by calling the IFullScreenVideoEx::SetEnabled. The Full Screen Renderer currently supports the display modes shown in the following table:

Mode Width Height Bit Depth
032020016
13202008
232024016
33202408
464040016
56404008
664048016
76404808
880060016
98006008
10102476816
1110247688
12115286416
1311528648
141280102416
15128010248

 

(All modes are RGB.) This list is subject to change, however. Use the IFullScreenVideoEx::GetModeInfo method to get information about the modes. The Full Screen Renderer always chooses the lowest-resolution mode available, limited by a property called the clip factor, which determines how much of the video the Full Screen Renderer is allowed to clip. For more information, see IFullScreenVideoEx::GetClipFactor.

When the application runs or pauses the filter graph, the Full Screen Renderer switches to the display mode that was chosen. When the graph stops, the Full Screen Renderer restores the original display mode.

The Full Screen Renderer can function only as the foreground active window. If the user switches to another application, the Full Screen Renderer hides the video by minimizing or hiding the video window.
