Wowza suing not appreciated “Dont discourage choice” – speaks community

we hate choice

The open  streaming media industry, developers and webhosts together have condemned Adobe’s move to sue Wowza media server. Adobe states that this is a case of “patent infringement and unfair competition“, but what this actually looks like is a slap on the face to the open streaming community. Adobe is perhaps trying to mention that nothing beyond Flash Media Server is acceptable to be used with flash, which now seems to be a more closed product day after day.

Passing configuration parameters into Red5 application

Often your Red5 project may need some external variable to be passed into Red5 application as a part of your configuration data, such that its not hard coded into the red5 application and you can change it as and when needed. For example : A database name, a configuration file path etc etc

 

Here we will demonstrate two ways to pass configuration data into Red5 application.

 

  1. Though red5-web.xml directly
  2. Through red5.properties routed via red5.xml

 

Passing parameters through red5-web.xml

This is the first method used to pass configuration data into your red5 application. In this example we will pass variable into the main application class.

 

package org.red5.core;

import org.red5.server.Scope;
import org.red5.server.adapter.ApplicationAdapter;
import org.red5.server.api.IConnection;
import org.red5.server.api.IScope;
import org.red5.server.api.service.ServiceUtils;

public class Application extends ApplicationAdapter {

public String database = "mydb.sqlite";

/** {@inheritDoc} */
@Override
public boolean appStart(IScope scope) {
return true;
}

@Override
public boolean connect(IConnection conn, IScope scope, Object[] params) {
return true;
}

@Override
public void disconnect(IConnection conn, IScope scope) {
super.disconnect(conn, scope);
}

public void setDatabase(String dbname)
{
database = dbname;
}

}

Note the last function: setDatabase this is the public setter function which will set the value of the variable database. Now the second part of this process is sending value to this function from outside Red5. For that we will be usingt the Red5 bean configuration file – red5-web.xml

So now we will edit the red5-web.xml file at the application’s bean handler definition and add the the variable property to it.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<!--
Defines a properties file for dereferencing variables
-->
<bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="location" value="/WEB-INF/red5-web.properties" />
</bean>

<!--
Defines the web context
-->
<bean id="web.context" class="org.red5.server.Context"
    autowire="byType" />

<!--
Defines the web scopes
-->
<bean id="web.scope" class="org.red5.server.WebScope"
     init-method="register">
    <property name="server" ref="red5.server" />
    <property name="parent" ref="global.scope" />
    <property name="context" ref="web.context" />
    <property name="handler" ref="web.handler" />
    <property name="contextPath" value="${webapp.contextPath}" />
    <property name="virtualHosts" value="${webapp.virtualHosts}" />
</bean>

<!--
Defines the web handler which acts as an applications endpoint
-->
<bean id="web.handler" class="org.red5.core.Application" singleton="true">
    <property name="database" value="mydb.sqlite"/>
</bean>

</beans>

Note the application bean definition to see how the database property is passed into the application bean handler to the public setter function

<bean id="web.handler" class="org.red5.core.Application" singleton="true">
    <property name="database" value="mydb.sqlite"/>
</bean>

At this stage it is important to note of the setter function is named:
public function setDatabase, like in the following format

setVariablename. The variable name is camel-cased along with the word”set”

IPhone Alarm Fails In New Year – Big Time Glitch!!

A glitch is iPhone’s alarm system managed to slow down the new year for many iPhone users, as they overslept due to a failure in the IOS 4 alarm system. Its a pity that as devices get more and more complex, manufacturers fail to make even the simplest things perfectly. Apple has said that a fix is in work.

This is the second incident, after apple products were found to have the most number of security flaws declaring it to be the world leader in security flaws. While the mac community continues to plow at Adobe’s Flash platform, at every given opportunity, i Products are starting to prevail manufacturing defects, at a steady pace.

Deploy applications to Red5 without restart

Although Red5 is well on its way to its  official 1.0 version (currently on 0.9.1), there are some things still not perfected for rigorous use. One of those crucial things is , installing/uninstalling applications without having to restart the entire server everytime.

The Hot-Deploy feature in Red5 lets you install RTMP applications to Red5 without having to disturb the running server. (more…)
