hello I've noticed the extension GLX_NV_video_out shows up in my GLX extension string. (using a GF4200Ti on Linux/X) However, I haven't found any information on it anywhere on the net but the function entry points in nvidia's glxext.h. Those still don't give me a real clue as to what the extension actually does. Anyone got a clue as to what it is supposed to do? My guess is that allows direct access to the TV out on nvidia cards..

Finally got an answer from nvidia's programming support. Just for the record, here's what I got in the reply:

Quote:
GLX_NV_video_out is a NVIDIA specific extension for use with
Quadro FX 4000 SDI.

This extension permits a color/depth pbuffer to be used for rendering
that is used display on a video output device (like SDI). p-buffers can
be 8-bits per component or fp16 per component. Once a p-buffer
is available to be displayed, it can be sent directly to the SDI
device (up to 10-bits per component).

This is pretty interresting because of the 10-bit component display, if you have one that supports it. Also, I guess it could be used for video overlays in linux..
