No camera image when using python code

[philippwulff]

I also needed to install these libraries besides the libraries in the instructions:

sudo apt-get install libjpeg-dev
sudo apt-get install libpng-dev
sudo apt install libfreetype6-dev

When attaching a camera and running python_bindings/test.py it opens a black window (no camera image). This is the terminal output:

rollbody@rollbody-desktop:~/picam360-capture/python_binding$ python3 test.py 
recv thread started : 9200

Just for others to compare, this is the output I got from building the code:
