Cannot get anything from NiViewer in Ubuntu16.04

Hello

   I just begin use Astra camera on Ubuntu, Linux.

   I download the latest version of OpenNI2.3.0.55 from Orbbec homepage, and run the NiViewer .

   However, I got the error of the image.

   Could you give me some suggestion about how to solve the problem?

   Thank you very much.

By the way, If I need to install the driver of Astra on Linux ?

However, there is only the driver installer for Windows… no linux version about it.

Got it.

running NiViewer with sudo ./NiViewer
