Visionworks 1.6 render problem

Hi,

I am using Jetson TX2 board and I am trying to run VisionWorks-1.6-Samples. I am making all the binaries successfully, however, I get the following error:

VisionWorks library info:
VisionWorks version : 1.6.0
OpenVX Standard version : 1.1.0

Error: Can’t create a renderer

Could you please let me know where is the problem?

Hi,

Do you have a display connected to TX2?
Thanks.

I am accessing it remotely using SSH. We have another jetson, with the same Jetpack 3.2 installed, and Visionworks 1.6, we receive the following error!

VisionWorks library info:
VisionWorks version : 1.6.0
OpenVX Standard version : 1.1.0

Error: Can’t open source URI /home/hmd88/VisionWorks-1.6-Samples/bin/…/data/cars.mp4

I have seen that people had this error also. The file is correct so that I can access it using the above address. and this happens for all the binaries of the Visionworks.

Hi,

Do you login in with nvidia account?
If not, please give it a try.

Thanks.

I found the problem. The problem was remote access to the Jetson!

So is it not possible to run OpenGL apps through X forwarding?
