Can I use Ably for audio and video streaming or images and file sharing?

By default, Ably does not support media streaming. However, you can still implement audio and video streaming with Ably by using it as a realtime signalling platform in conjunction with other protocols such as WebRTC etc, but the media streams themselves would use a separate protocol such as RTSP.

Please see our WebRTC tutorials for details on how to use WebRTC for audio, video, screen sharing and file sharing, whilst using Ably (or any other pub/sub system) for the signalling.
