Red5 Remoting

Remoting a facility by which a client can call a server method in a  request response fashion. Unlike RTMP remoting services are performed using AMF over HTTP/HTTPS. Red5 can act as both a RTMP server as well as a HTTP/HTTPS remoting server. Remoting enables non rtmp clients to access Red5 methods.  A very practical approach would be to request chat room user count for example. Using remoting you can request such data without consuming too much server resources as in a RTMP connection. You can also create chat programs with simple amf-polling as well. Remoting also lets you sync data types over both ends (client-server) (more…)

Red5 – Online Application Generator


The Red5 Online Application Generator is a very simple but effective utility to generate Red5 application online. Do not worry if you don’t know Red5 or even Java. Generate streamer applications, with live broadcasting, streaming, recording and sharedObject capabilities in a single click. No compiling/editing needed. The generator creates red5 applications for you on the fly by injecting necessary information into pre-compiled red5 application templates and prepares them for hassle free use. (more…)

Ready to use – Red5 streamer application

Following Red5 Developer series from Dominick Accattato, and a neat explaination from Red5.org on CustomFilenameGenerator, Here is a ready to use, fully capable pre-compiled Red5 application for anyone who wishes to set up Flash streaming with Red5 , but does not know where to start.

The application is tested on Red5 0.8. to use it in 0.9 you may have to remove the bandwidth-setting code in main Application class and recompile it.

How to configure Stream/Record paths:


1. Edit the file file red5-web.xml in the WEB-INF directory

2. Move down to the “streamFilenameGenerator” bean definition and adjust values of recordPath and playbackPath as you wish.

3. To use absolute paths, set “absolutePath” property as true.

Connecting Red5 and Amf-php

Its been a long goal for me to connect Red5 to amfphp. You will see frequent needs of interacting with MySQL database from red5. Many people suggest using JDBC. Although thats  valid suggestion, its more of a headache for a non Java developer and the server administrator. Many people also suggest using flash to amfphp direct., but mind it thats the most incorrect way of doing things, when you want it secure.

Here is how you actually get Java to talk to php, the modern style :).  First anf foremost grab a copy of amfphp 1.2 from Sourceforge. Note: download amfphp 1.2,  as amfphp 1.9 is not compatible with red5’s amf decoding.

Step 1.  Setup the amfphp gateway at your server root. Like so:

http://localhost/amfphp

See video on setting up amfphp

Step 2. Download and install red5, then setup a new application using red5plugin in eclipse. (i wont discuss how to setup red5 application here. you can refer to external links for that. Mainly: Red5 developer series videos)

Step 3.  Create a new amfphp service class like this and save as Red5Service.php in services folder of amfphp.

<?php
class Red5Service
{

function  Red5Service()
{
$this->methodTable = array(
"login" => array(
"description" => "login user -> returns true/false",
"access" => "remote",
"arguments" => array ("username","password")
),
"logout" => array(
"description" => "logout user -> returns nothing",
"access" => "remote",
"arguments" => array ("username")
)  
);
}  

function login($username,$password)
{
return true;
}

function logout($username)
{
return;
}
}
?>

Step 4. In your red5 application, connect method  place a call to your amfphp service,  as shown below:

/** {@inheritDoc} */
@Override
public boolean connect(IConnection conn, IScope scope, Object[] params)
{
try
{
RemotingClient client = new RemotingClient("http://localhost/amfphp/gateway.php");
Object[] args = new Object[]{'rajdeep','xyz123'};
Object result = client.invokeMethod("Red5Service.login", args);

if(!result.equals(true)) return false; 
}
catch (IOException e)
{
return false;
}
return true;   
}

As you will see when a user connects to red5 application, the connect handler makes a connection to amfphp gateway and sends the parameters ‘rajdeep’ and ‘xyz123’ as arguments. the amf service can then do its own computations as you want it to and return a boolean expression – true/false at the end. If the java RemotingClient receives a true it lets the connect method accepts the connection else reject it. Also note the try catch block.  also since we dont know what network situations may prevail, so need to be sure that if red5 cannot connect to amfphp it will reject the client connection anyways.

Thats all  for the basics to make things hotter try experimenting with params sent to red5 from flash and the database stuff 🙂
