| # Enable Screen Capturing using [Firefox Extensions API](https://github.com/muaz-khan/Firefox-Extensions) | ||
|
|
||
| Enable screen capturing using Firefox (for https://www.webrtc-experiment.com demos only): | ||
|
|
||
| * [enable-screen-capturing.xpi](https://www.webrtc-experiment.com/store/firefox-extension/enable-screen-capturing.xpi) | ||
|
|
||
| To use in your own domains: | ||
|
|
||
| Modify `bootstrap.js` file, line 18: | ||
|
|
||
| ```javascript | ||
| ['yourDomain.com', 'www.yourDomain.com'].forEach(function(domain) { | ||
| if (values.indexOf(domain) === -1) { | ||
| values.push(domain); | ||
| addon_domains.push(domain); | ||
| } | ||
| }); | ||
| ``` | ||
|
|
||
| And modify `install.rdf` for you extension information (name, URL, icon etc.) | ||

| # [WebRTC Scalable Broadcast](https://github.com/muaz-khan/WebRTC-Scalable-Broadcast) | ||
|
|
||
| Scalable WebRTC peer-to-peer broadcasting demo. | ||
|
|
||
| [](https://npmjs.org/package/webrtc-scalable-broadcast) [](https://npmjs.org/package/webrtc-scalable-broadcast) | ||
|
|
||
| This module simply initializes socket.io and configures it in a way that single broadcast can be relayed over unlimited users without any bandwidth/CPU usage issues. Everything happens peer-to-peer! | ||
|
|
||
| ``` | ||
| npm install webrtc-scalable-broadcast | ||
| node .\node_modules\webrtc-scalable-broadcast\server.js | ||
| ``` | ||
|
|
||
| And now open: `http://localhost:8888`. | ||
|
|
||
| ## How it works? | ||
|
|
||
| This demo runs top over [RTCMultiConnection.js](http://www.RTCMultiConnection.org/). Though, you can use it in any other [WebRTC Experiment](https://www.webrtc-experiment.com/). | ||
|
|
||
| It following technique mentioned here: | ||
|
|
||
| * https://github.com/muaz-khan/WebRTC-Experiment/issues/2 | ||
|
|
||
|  | ||
|
|
||
| Assuming peers 1-to-10: | ||
|
|
||
| ### First Peer: | ||
|
|
||
| Peer1 is the only peer that invokes `getUserMedia`. Rest of the peers will simply [forward/relay remote stream](https://www.webrtc-experiment.com/RTCMultiConnection/remote-stream-forwarding.html). | ||
|
|
||
| ``` | ||
| peer1 captures user-media | ||
| peer1 starts the room | ||
| ``` | ||
|
|
||
| ### Second Peer: | ||
|
|
||
| ``` | ||
| peer2 joins the room | ||
| peer2 gets remote stream from peer1 | ||
| peer2 opens a "parallel" broadcasting peer named as "peer2-broadcaster" | ||
| ``` | ||
|
|
||
| ### Third Peer: | ||
|
|
||
| ``` | ||
| peer3 joins the room | ||
| peer3 gets remote stream from peer2 | ||
| peer3 opens a "parallel" broadcasting peer named as "peer3-broadcaster" | ||
| ``` | ||
|
|
||
| ### Fourth Peer: | ||
|
|
||
| ``` | ||
| peer4 joins the room | ||
| peer4 gets remote stream from peer3 | ||
| peer4 opens a "parallel" broadcasting peer named as "peer4-broadcaster" | ||
| ``` | ||
|
|
||
| ### Fifth Peer: | ||
|
|
||
| ``` | ||
| peer5 joins the room | ||
| peer5 gets remote stream from peer4 | ||
| peer5 opens a "parallel" broadcasting peer named as "peer5-broadcaster" | ||
| ``` | ||
|
|
||
| and 10th peer: | ||
|
|
||
| ``` | ||
| peer10 joins the room | ||
| peer10 gets remote stream from peer9 | ||
| peer10 opens a "parallel" broadcasting peer named as "peer10-broadcaster" | ||
| ``` | ||
|
|
||
| ## Conclusion | ||
|
|
||
| 1. Peer9 gets remote stream from peer8 | ||
| 2. Peer15 gets remote stream from peer14 | ||
| 3. Peer50 gets remote stream from peer49 | ||
|
|
||
| and so on. | ||
|
|
||
| ## Limitation | ||
|
|
||
| This demo works only with screen and video-only streams. It doesn't works with audio. | ||
|
|
||
| Because currently [remote audio processing](https://www.webrtc-experiment.com/demos/remote-stream-recording.html) or forwarding isn't supported in chrome. | ||
|
|
||
| This demo works only in Chrome; no Firefox support yet. Because Firefox isn't supporting non-APM sources for peer-streaming. | ||
