Chris Cox, Facebook's chief product officer, says that live video is a lot harder than simply streaming video. That's because it has to work no matter what kind of device and what kind of connection you have. "There's a real-time raw authentic moment, shared by a lot of people instantaneously," he said. On the professional side of things, he said that Facebook has already been working with several partners like BuzzFeed and Tastemade to stream live shows. As for the drone video, he says that if you own a DJI Phantom, all you need is a software update to be able to stream live -- the firmware should arrive in the next few months.
