Grabber::getProperty Method

Grabber::getProperty Method

Returns the actual value of a property of the current video capture device.
Syntax:
long getProperty( tCameraPropertyEnum CameraPropType ) const;
long getProperty( tVideoPropertyEnum VideoPropType ) const;
Parameter Description
CameraPropType

Specifies the camera property to be queried. The possible properties are specified in Grabber::tCameraPropertyEnum.

VideoPropType

Specifies the video property to be queried. The possible properties are specified by Grabber::tVideoPropertyEnum.

Return value:

The current value of the given property.

Remarks:

This method returns the value of the specified property. The range of possible values can be determined by calling Grabber::getPropertyRange. Grabber::getPropertyDefault returns the default value for the specified property.

If an error occurred, 0 is returned, which may also be a valid property value. You should use Grabber::getLastError to determine whether an error occurred or not.

Note that the value for a property may only be queried, if "automatic mode" is disabled.
