Dear happyuser, i’m working on the same project that you in France but to carry all the video platform in a drone with the lower weight possible (250/300g max without the power unit).
I’ve a mini linux web video server with HD 720p video features to make this project with two USB key 3G modems.
I’ve just seen the Zeroshell solutions who are very good between two hards and heavy platforms but may be not easy to work for a mobile solution.
I’ve tried many others possibilities under Android with openvpn and Gstreamer without success and the wall of the private IP adress on the 3G network is very difficult to solve without use a bigger and higher weight platform..
Have you find some issues who can be a new track for me, please?
