YouTube has made a major revision to its iOS app, and has added the ability for game players or app demonstrators to stream the entire contents of an iPhone or iPad directly to the video service.
The latest YouTube app implements Apple's ReplayKit API to allow for streaming screen contents from any compatible app. Streamers can use the device's microphone and front-facing camera to add video and audio commentary to the stream.
Other improvements include a reduction in latency to "a couple of seconds" to allow for real-time interaction with viewers, and new chat moderation abilities including the ability to assign a moderator to take care of the chat during the stream.
Users interested in live streaming must be verified, and have no live stream restrictions in the previous 90 days. All of the new features are online now, and available to accounts that are able to stream.
The YouTube app itself requires iOS 9 or greater, and occupies 150MB of storage space.
