IMFVideoDisplayControl::SetFullscreen Method
[This API is not supported and may be altered or unavailable in the future. ]
Sets or unsets full-screen rendering mode.
To implement full-screen playback, an application should simply resize the video window to cover the entire area of the monitor. Also set the window to be a topmost window, so that the application receives all mouse-click messages. For more information about topmost windows, see the documentation for the SetWindowPos function.
Syntax
HRESULT SetFullscreen(
[in] BOOL fFullscreen
);
Parameter
- fFullscreen [in]
If TRUE, the enhanced video renderer (EVR) uses full-screen mode. If FALSE, the EVR draws the video in the application-provided clipping window.
Rückgabewert
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Rückgabecode | Beschreibung |
|---|---|
| S_OK | The method succeeded. |
| MF_E_SHUTDOWN | The video renderer has been shut down. |
Hinweise
The default EVR presenter implements full-screen mode using Direct3D exclusive mode.
If you use this method to switch to full-screen mode, set the application window to be a topmost window and resize the window to cover the entire monitor. This ensures that the application window receives all mouse-click messages. Also set the keyboard focus to the application window. When you switch out of full-screen mode, restore the window's original size and position.
By default, the cursor is still visible in full-screen mode. To hide the cursor, call ShowCursor.
The transition to and from full-screen mode occurs asynchronously. To get the current mode, call IMFVideoDisplayControl::GetFullscreen.
