Method Detail

glEnumerateVideoDevicesNV

public static int glEnumerateVideoDevicesNV(java.nio.LongBuffer devices)

Enumerate the available video output devices. This method is the cross-platform equivalent of glXEnumerateVideoDevicesNV and wglEnumerateVideoDevicesNV. 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 output devices

glBindVideoDeviceNV

public static boolean glBindVideoDeviceNV(int video_slot,
                                          long video_device,
                                          java.nio.IntBuffer attrib_list)

Binds the video output device specified to one of the context's available video output slots. This method is the cross-platform equivalent of glXBindVideoDeviceNV and wglBindVideoDeviceNV. To release a video device without binding another device to the same slot, call it with video_device set to 0 (will use INVALID_HANDLE_VALUE on WGL).

Parameters:

video_slot - the video slot

video_device - the video device

attrib_list - the attributes to use

Returns:

true if the binding was successful

glQueryContextNV

public static boolean glQueryContextNV(int attrib,
                                       java.nio.IntBuffer value)

Queries an attribute associated with the current context. This method is the cross-platform equivalent of glXQueryContext and wglQueryCurrentContextNV.

Parameters:

attrib - the attribute to query

value - the buffer to store the value in
