Grabber::isDevOpen Method

Checks whether a video capture device is opened.
bool isDevOpen() const;
Return value:

true, if a device is associated with this object, false otherwise.


Checks whether a video capture device is associated with this object.

If the device was opened with Grabber::openDev and has become invalid in the meantime (e.g. the device has been unplugged), this method will still return true. The Grabber::isDevValid method can be used to determine whether the video capture device is accessible.
