* NV_CTRL_GVO_GLX_LOCKED - indicates that GVO configurability is

locked by

* GLX; 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, setting of the following GVO NV-CONTROL

attributes will

* not happen immediately and will instead be cached. The GVO resource

will

* need to be disabled/released and re-enabled/claimed for the values

to be

* flushed. These attributes are:

* NV_CTRL_GVIO_REQUESTED_VIDEO_FORMAT

* NV_CTRL_GVO_DATA_FORMAT

* NV_CTRL_GVO_FLIP_QUEUE_SIZE

* XXX This is deprecated, please see NV_CTRL_GVO_LOCK_OWNER

* NV_CTRL_GVIO_VIDEO_FORMAT_{WIDTH,HEIGHT,REFRESH_RATE} - query the

* width, height, and refresh rate for the specified

* NV_CTRL_GVIO_VIDEO_FORMAT_*. So that this can be queried with

* existing interfaces, XNVCTRLQueryAttribute() should be used, and

* the video format specified in the display_mask field; eg:

* XNVCTRLQueryAttribute (dpy,

* screen,

NV_CTRL_GVIO_VIDEO_FORMAT_487I_59_94_SMPTE259_NTSC,

* NV_CTRL_GVIO_VIDEO_FORMAT_WIDTH,

* &value);

* Note that Refresh Rate is in milliHertz values
