    • Method Detail

      • glBindVideoCaptureDeviceNV

        public static boolean glBindVideoCaptureDeviceNV​(int video_slot,
                                                 long device)
        After successfully locking a video capture device, use this method to bind it to the capture slot specified in the current context. This method is the cross- platform equivalent of glXBindVideoCaptureDeviceNV and wglBindVideoCaptureDeviceNV.
        Parameters:
        video_slot - the video slot
        device - the video capture device
        Returns:
        true if the binding was successful

      • glEnumerateVideoCaptureDevicesNV

        public static int glEnumerateVideoCaptureDevicesNV​(LongBuffer devices)
        Enumerate the available video capture devices. This method is the cross-platform equivalent of glXEnumerateVideoCaptureDevicesNV and wglEnumerateVideoCaptureDevicesNV. Since they are not really compatible, this method works like the WGL version. That is, you first call it with a null devices buffer, get the number of devices, then call it again with an appropriately sized buffer.
        Parameters:
        devices - the buffer to store devices in
        Returns:
        the number of available video capture devices

      • glLockVideoCaptureDeviceNV

        public static boolean glLockVideoCaptureDeviceNV​(long device)
        To lock a video capture device to a display connection, use this method. Before using a video capture device, it must be locked. Once a video capture device is locked by a process, no other process can lock a video capture device with the same unique ID until the lock is released or the process ends.
        Parameters:
        device - the device to lock
        Returns:
        true if the lock was successful

      • glQueryVideoCaptureDeviceNV

        public static boolean glQueryVideoCaptureDeviceNV​(long device,
                                                  int attribute,
                                                  IntBuffer value)
        Use this method to query the unique ID of the physical device backing a video capture device handle.
        Parameters:
        device - the device
        attribute - the attribute to query
        value - the buffer to store the value in
        Returns:
        true if the query was successful

      • glReleaseVideoCaptureDeviceNV

        public static boolean glReleaseVideoCaptureDeviceNV​(long device)
        Use this method when finished capturing data on a locked video capture device to unlock it.
        Parameters:
        device - the device
        Returns:
        true if the device was unlocked successfully
