PROJECT

Drone Live Video Streaming Solution using Raspberry PI
Team Project | HIFLY
We implemented a streaming system which can forward live video stream to multiple users from a Phantom4, a drone made by DJI. Also, we constructed the streaming server on Raspberry Pi 3 board for high mobility. The video stream can be played on any devices if the HTML5 standard web browser is utilized. [Video] [Github page]
