A full discussion of security for streaming media is out of scope for this article. Testing Some of the samples have an associated test. For two devices in different networks to find each other they need to use a central service called a signaling server. To join the same room, choose the same room name each time, such as 'foo'. This is excellent because it means that our connection succeeded! Once we have an offer gotDescription was called , we set the local description to it and then send it to the signaling server to be sent to the other client. Technology doesn't get much more than this. Set that as the source of the remote video element.

These handlers can do whatever's needed, but in this example, all we need to do is update the user interface: function handleLocalAddCandidateSuccess { connectButton. The we built uses running on a.

A tutorial and example which turns a WebSocket-based chat system created for a previous example and adds support for opening video calls among participants. Otherwise threads and connections are kept alive. You can still continue with the codelab! Add video elements and control buttons In index. It updates the local description of the connection. MultiStreamsMixer Pass multiple streams e. One video element will show our local camera feed, and the other video element will play the video and audio feed from the remote peer. A promised based call back which returns local stream on success navigator.

If network restrictions prevent peers from communication directly at all, the traffic is routed via a server. Thereafter the user is not asked for permission for camera or microphone access. We grab references to all the page elements we'll need to access, then set on the three buttons. Notice the use of dataConstraint. Once you've done that, let's walk through it together as well.

The expression 'finding candidates' refers to the process of finding network interfaces and ports using the framework. It is used to handle efficient streaming of data between the two peers. While that's obviously a contrived scenario, it's useful for demonstrating the flow of connecting two peers. Choosing the right signaling server This codelab uses for a signaling server. The browser will calculate the height automatically: video { max-width: 100%; width: 320px; } Next up You've got video, but how do you stream it? Install and verify web server While you're free to use your own web server, this codelab is designed to work well with the Chrome Web Server.

If you don't have that app installed yet, you can install it from the Chrome Web Store. The interface is a feature which lets you open a channel between two peers over which you may send and receive arbitrary data. When you are no longer using a track make sure to call track. Understanding the Code Now comes the fun part. You'll add functionality and layout features in subsequent steps. This is then sent to the remote peer by calling.

Represents the identity of the remote peer of the current connection. A complete version of this step is in the step-05 folder. This is done by calling remoteConnection. These commands will be indicated later, when they are required. In a real world application, one video element would display the local stream and the other the remote stream. Now the remoteConnection knows about the connection that's being built. The sendData and createConnection functions have most of the new code: function createConnection { dataChannelSend.

An array of MediaStreamTracks is returned by the getAudioTracks and getVideoTracks methods. A complete version of this step is in the step-04 folder. The exchange of information via signaling must have completed successfully before peer-to-peer streaming can begin. In a real application, this process known as signaling takes place via a messaging service — you'll learn how to do that in a later step. You can view a demo showing how to use constraints to request different resolutions , and a demo using constraints to choose camera and microphone. We'll cover the mechanics of accomplishing the connection and transmitting and receiving data, but we will save the bits about locating and linking to a remote computer for another example.
