OK - I have managed to run the script after using your .sh installation script, but... When I run node index.js -o I get like 100x512 Bytes of data and thats it.... It's not a continous stream. It's like it just sends a bunch of data and stops. Not sure what's wrong.

Got the same problem. I didn't managed to have any kind of output.
