   GLX_NV_video_out
  helloI'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..   
  Interesting, I never noticed this extension. Strange that Google only returns one single result, being the said glxext.h. Maybe try posting this in the opengl.org developer forums ? There are a few guys from the nVidia driver development team on there.;  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 withQuadro 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 canbe 8-bits per component or fp16 per component.  Once a p-bufferis available to be displayed, it can be sent directly to the SDIdevice (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..
