Accessing Gazebo Camera Using Application Outside ROS

I have succesfully running Gazebo 8 + Ardupilot SITL on Ubuntu 16.04, I also succesfully using Mavproxy to interact SITL with a simple python script (Using Dronekit not ROS application). My question is there any method/tutorial to interact with the Gazebo camera to application outside ROS ? Maybe using UDP/TCP stream ? Or virtual webcam ? Thank you.

Did you find a way to do this?
I’m looking for the same thing. Actually I can’t even get the Gazebo camera to work with ROS, the documentation website says this is done through the “ros_gazebo_camera” package, however I can’t find this package anywhere.
