Real Time Message Protocol (RTMP) messaging library in JavaScript

Real Time Message Protocol (RTMP) messaging library in JavaScript

Prototype implementation of the RTMP protocol. Based on the RTMP specification at http://www.adobe.com/devnet/rtmp.html. Currently only Firefox in special configuration is supported. The RTMP or RTMPT requires either TCP sockets or unrestricted access to XHR. The Firefox (OS) provides both of those features: TCPSocket or systemXHR.

Try running demo-rtmp.html in the browser and monitoring the traffic in the web console. Use a local web server (e.g. python -m SimpleHTTPServer) for that.

Setting up the desktop browser

The security reasons, the desktop browser disables access to the HTTP traffic from the sites that are located in different domains. Also it has no means to communicate over TCP protocol by default. The Firefox OS introduces the following APIs:

• systemXHR (see mozSystem parameter for XMLHttpRequest at https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest);
• TCPSocket API (see https://developer.mozilla.org/en-US/docs/DOM/TCPSocket)

To enable that for desktop, follow the instructions at https://github.com/mozilla-b2g/gaia/blob/master/apps/email/README.md :

• Turn on mozTCPSocket -- in about:config, create "dom.mozTCPSocket.enabled";
• Grant permission for certain URL, e.g. evaluate in the error console:

host = 'http://test.local:8000';
perm = Components.classes["@mozilla.org/permissionmanager;1"]
                 .createInstance(Components.interfaces.nsIPermissionManager);
ios = Components.classes["@mozilla.org/network/io-service;1"]
                .getService(Components.interfaces.nsIIOService);
uri = ios.newURI(host, null, null);
perm.add(uri, 'systemXHR', 1);
perm.add(uri, 'tcp-socket', 1);
'Successfully added systemXHR and tcp-socket permissions for '+host;

Setting up RTMP server

The Red5 server (http://www.red5.org/) is used for testing. Its download can be found at http://red5.org/downloads/red5/1_0/red5-1.0.0.tar.gz. Navigate to http://localhost:5080/installer/ at install the "OFLA Demo" application.
