WebRTC Tutorial
You'll add functionality and layout features in subsequent steps. Plus you get your personal call address to serve as your web phone number Web Site: Serialized, an SDP object looks like this:. It is free to use. In a real world application, the sender and receiver RTCPeerConnections run in web pages on different devices, and you need a way for them to communicate metadata. That's not very useful, but does demonstrate how WebRTC can be used to share data as well as streaming video. Chat service provides users with an opportunity to exchange messages by establishing a direct connection between their browsers and uses Pear to Pear method of online communication.

What is signaling?

This also allows support for other constraints such as aspect ratio, facing mode front or back camera , frame rate, height and width, along with an applyConstraints method. There's an example at webrtc. For example if a camera was opened in x mode by one tab, another tab will not be able to use constraints to open it in a higher-resolution mode since it can only be opened in one mode. Note that this is an implementation detail: Setting a disallowed constraint value gives a DOMException, or an OverconstrainedError if for example a resolution requested is not available.

To see this in action, try the demo at webrtc. Chrome apps also make it possible to share a live 'video' of a single browser tab or the entire desktop via chrome. A few years old, but still interesting. It's also possible to use screen capture as a MediaStream source in Chrome using the experimental chromeMediaSource constraint, as in this demo.

Note that screen capture requires HTTPS and should only be used for development due to it being enabled via a command line flag as explaind in this discuss-webrtc post. WebRTC uses RTCPeerConnection to communicate streaming data between browsers aka peers , but also needs a mechanism to coordinate communication and to send control messages, a process known as signaling.

Signaling methods and protocols are not specified by WebRTC: The codelab we built uses Socket. The exchange of information via signaling must have completed successfully before peer-to-peer streaming can begin. For example, imagine Alice wants to communicate with Bob.

The code assumes the existence of some signaling mechanism, created in the createSignalingChannel method. First up, Alice and Bob exchange network information. The expression 'finding candidates' refers to the process of finding network interfaces and ports using the ICE framework. WebRTC clients known as peers , aka Alice and Bob also need to ascertain and exchange local and remote audio and video media information, such as resolution and codec capabilities.

Signaling to exchange media configuration information proceeds by exchanging an offer and an answer using the Session Description Protocol SDP:. Make sure to allow the RTCPeerConnection to be garbage collected by calling close when it's no longer needed. Otherwise threads and connections are kept alive. It's possible to leak heavy resources in WebRTC! Serialized, an SDP object looks like this:. The acquisition and exchange of network and media information can be done simultaneously, but both processes must have completed before audio and video streaming between peers can begin.

There's an excellent animation explaining the process of signaling and streaming in Ericsson's demo video for its first WebRTC implementation. Once the signaling process has completed successfully, data can be streamed directly peer to peer, between the caller and callee—or if that fails, via an intermediary relay server more about that below.

As you will notice, the green parts are complex! From a JavaScript perspective, the main thing to understand from this diagram is that RTCPeerConnection shields web developers from the myriad complexities that lurk beneath.

Leveraging the power of WebRTC and HTML5, the RingRTC webclient creates a direct, secure connection between the phone and the web browser, allowing business users to use the big screen and keyboard to manage their phone.
