WebRTC (Web Real-Time Communication) is a technology that enables real-time communication, such as video and audio streaming, file sharing, and screen sharing, directly through a web browser. This eliminates the need for plugins or third-party applications, making it easy for users to connect and collaborate in real-time.
One of the key components of a WebRTC system is the media server, which is responsible for handling the media streams and facilitating communication between clients. There are many commercial media servers available, but for those looking for a cost-effective and customizable solution, open-source media servers are a great option.
