NV_CTRL_GVO_LOCKED

/*
 * NV_CTRL_GVO_LOCKED - indicates that GVO configurability is locked;
 * this occurs when the GLX_NV_video_out function calls
 * glXGetVideoDeviceNV().  All GVO output resources are locked until
 * either glXReleaseVideoDeviceNV() is called or the X Display used
 * when calling glXGetVideoDeviceNV() is closed.
 *
 * When GVO is locked; all GVO NV-CONTROL attributes are read only.
