In the coming weeks, Periscope will be launching broadcast search and drone support, which will allow you to broadcast from your DJI supported drone, (which is almost all the new ones) and GoPros.
For those of you who don't know. Periscope broadcasts live video footage as it's happening via your phone, and sharing it with basically the whole world, or just a few friends.
According to Periscope, you just "connect your iPhone to your drone’s remote," and Periscope will then begin to pull the footage and broadcast it to their network. In addition, you'll be able to narrate and use an all new sketch feature while your drone is flying around.
iPhone 5S, 6, 6+, 6S, 6S+ with iOS 8.2 or above
DJI Inspire, Phantom 4, Phantom 3 Professional or Advanced, Osmo
