Hello all,

I'm trying to record a tutorial video. I have Blender 2.76 open but NDI doesn't show the screen. In the NDI window, it shows a preview of the vMix screen. In the local desktop capture settings, it only shows software icons. Please see images below.

NDI
Local desktop capture
vMix

I can hit record, minimize vMix, work in Blender, return to vMix and play video. It does record what I do in Blender but it's aggravating to not be able to record it within vMix.

I am running a Windows 10 laptop with nvidia geforce.

Any help is appreciated. Thanks in advance.

Quite often apps that leverage hardware acceleration cannot be captured using a pure software approach. In essence, the screen capture capability in software occurs before the hardware layer that's actually handling the video stream.

You option are:

(1) Try to disable hardware acceleration in Blender or your GPU driver.

(2) Capture the video card output via hardware to a different system. (My preferred approach)

Try using NDI Scan Converter (part of NDI Tools 3.6) to capture the screen. The code mostly runs in the GPU, so it should work with applications using hardware acceleration (NDI Scan Converter is designed to capture video games).

You do have to be running Windows 8 or 10 for this tool to operate.

Thank you both for the info and the NDI tools download. I'll try the download and see if that helps. Thanks.
