View Full Version : NTSC & OpenGL buffer realtime mixing !

02-06-2002, 10:36 AM
Hi folks !

We need to do the following :
On a NTSC video signal (analogic) we need to overlap a layer (buffer) made by an OpenGL Hardware.

We'd like the mixing to be done on the machine where the OpenGL program runs.

Is there a grabbing card that can get the analog signal and that have a OpenGL Hardware and that could do the mixt ?

We don't want to use an external analogic mixer.

Another option would be to simply get the analog signal through an ordinary Grabber and use the video image in the OpenGL rendering process. Would it be efficiant ?

Thanks for any help !
