Rendering GPU data on decklink
on Jul 22, 2012 at 9:28:04 am

I have a requirement to render GPU data which is normally rendered at GPU using Opengl on the decklink card. Currently I am using glReadPixels and then rendering on decklink.

This process is very slow as it takes time to transfer pixels from GPU to cpu and then back to decklink card. Is there any alternate solution to achieve this.
