Though it will only be possible through the Periscope iOS app.
Twitter has just announced that you can now livestream your GoPro camera directly through the Periscope app. The new update, which should be rolling out now, will allow you to do a livestream from your camera directly to Periscope when it is connected to your smartphone.
Once connected, Periscope will give you the option to livestream straight from your GoPro. You can also switch from your iPhone camera to the GoPro camera with a flick of a switch. All GoPro Hero 4 lines except the Session are supported, though only the iOS version of Periscope supports the feature.
The update will be a welcome news to all GoPro users, which enables them to directly share livestreams online without the hassles of copying and editing footage.
