Daily provides an API that allows developers to add real-time video calls to any app or website and make them easily accessible on platforms such as Amazon IVS, YouTube Live, Facebook Live, and Mux. To do this, users need to create a room and a meeting token, which identifies them as the owner of that room, and set up a stream with a streaming provider like YouTube. Daily handles the encoding and transcoding of the RTMP stream, allowing for low-latency communication and live streaming capabilities. With just a few lines of code, developers can create a fully functional live streaming room that can be broadcast to multiple viewers, with recommended participant limits to ensure smooth audio and video quality.
