Getting black screen on running ./sampleLite on Ubuntu 14.04

Postby yugansh.mohan » Fri Nov 10, 2017 3:38 am

Hi there,

I'm trying to use an external webcam with Artoolkit 5 on Ubuntu 14.04.
I followed the README.txt file step by step, unpacked the .tar.gz and set the environment through artoolkit5-setenv successfully.
Then, I set the environment variable ARTOOLKIT5_CONF with the command ' export ARTOOLKIT5_VCONF="-device=LinuxV4L2" '.
But when I run ./simpleLite, all I get is a black screen.

The same steps work for my Ubuntu 14.04 laptop with an internal camera. The problem occurs on my desktop which doesn't have an internal camera, hence I'm using an external camera.

The camera is working fine with VLC, Cheese etc.

This is what I get on the terminal when I run ./simpleLite

Code: Select all

Using default video config.
