Cannot capture two different camera stream on Visionworks


I would like to get two different camera stream in the same program(tracking sample). Even though, I create two different context and render instances, the second render always shows blank. I did try various variations such as duplicating first frame stream into the second render yet, I cannot get any image only the blank on second render.
is the render singleton?

My main goal is to get two video streams side by side.



Could you share your implementation with us so we can check it directly?
If you want to display the streams side-by-side, you can stitch the them together and use one render for it.

Maybe you can check if our stereo_matching sample for some idea:
