IFullScreenVideoEx::IsModeEnabled method (amvideo.h)
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
The IsModeEnabled method queries whether a specified display mode is enabled.
Syntax
HRESULT IsModeEnabled(
[in] long Mode
);
Parameters
[in] Mode
Index of the display mode to query.
Return value
Returns an HRESULT value. Possible values include the following.
| Return code | Description |
|---|---|
|
Index out of range. |
|
The display mode is disabled. |
|
The display mode is enabled. |
Remarks
The Full Screen Renderer supports a static set of display modes. By default, every mode is enabled. You can enable or disable a display mode by calling the IFullScreenVideoEx::SetEnabled. The IsEnabled method retrieves the current setting for the specified mode.
The video card on the user's system might not support every mode. The Full Screen Renderer will not use a mode that the video card does not support, even if that mode is enabled. To determine whether the card supports a particular mode, call the IFullScreenVideoEx::IsModeAvailable method. If a mode is disabled, the Full Screen Renderer will not use it, even if the card supports it.
Display modes are indexed from zero. The IFullScreenVideoEx::CountModes method returns the number of modes.
