CREATE NEW JAVA RED5 APPLICATION

January 29, 2007 at 10:33 pm Filed under Red5 Tagged application, java, new, Red5

During this tutorial, we will be using Joachims migration guide:http://www.joachim-bauch.de/tutorials/red5/MigrationGuide.txt

In this tutorial we will be examining how to create applications in the Red5 Standalone Server. TheRed5 Standalone Server uses a Spring Framework Managed Jetty Embeddable Http Server andServlet container. The Spring Framework is a JAVA Framework that provides hooks (configurationmetadata is in the form of either XML bean definitions, JAVA properties file or by calling theconfigurable items of the Spring API from within your POJO-Plain Old JAVA Object) throughwhich you can control the behaviour of various JAVA applications, objects or frameworks (eg Jetty,Acegi, Hibernate). This allows you to leverage a broad array of JAVA technologies from within yourPOJO without having to face the challenge of coding to interface to all these JAVA objects yourselfwhile still ensuring you adhere the common JAVA Design Patterns. In addition, by making use ofthe hooks provided by Spring to influence your applications behaviour by editing the configurationmetadata (See Dependency Injection), you can easily change the behaviour of your applicationwhile leaving your core POJOs intact.Because of IoC, ones application can be developed using a set of simple JavaBeans (or plain-old Java

objectsPOJOs), with a a lightweight IoC container (Spring) wiring them together and setting thedependencies.The XML configuration metadata and is used by Springs IoC to create a fully configured system orapplication. This configuration metadata tells the Spring container how to instantiate, configure,and assemble [the objects in your application].

In addition, you will also learn about the scope of a red5 application, as well as how to create anduse server side shared objects.

Before beginning this tutorial, you may download the red5java application explained from here:red5java.tar.gzExtract the contents of this folder into your red5_server/webapps directory.

and the demo flex2 client from here:red5_flexclient.tar.gz

1. Get into the root directory of the red5 server which in my case was red5_server

#cd /opt/red5_server/webapps



This is the root folder of all your red5 application definitions, from which all red5 applications arestarted. This is the global scope. If you are running a hosting service this would be your root folder.To create a section for each hosted user you would create a WEB-INF/user-dir as shown below;

2. Create your new application as follows (The new application name for this tutorial will be calledred5java)

#mkdir -p red5java/WEB-INF

re5java is the name of your application in this example. You will access your application using theURL rtmp://your-ip/red5java or rtmpt//your-ip/red5java in the case of a proxy-tunneled RTMPTconnection). The WEB-INF folder is so that Jetty (the Embeddable HTTP Server and ServletContainer that is used by the Standalone red5 server) knows where to access your application(Servlet) from. This is because your application is actually a JAVA servlet. It is in the WEB-INF filethat you will load all the configuration files/beans that will be required to load your application.These files specify all the Spring beans that your application will require as well as bean definitionsthat will be used by Spring to Dependency Inject your application. These config files includeweb.xml, red5-web.xml, red5-web.properties and log4j.properties as will be shown below.

Under the red5java directory create a folder called src where you will create your own customapplication that will be used to communicate with the Flash clients.

#mkdir src

This would also be a good point at which to create your classes (for the classes) and lib (for the jarfile) directories. We will also be doing this in the ant build file below but so that we get the concept,lets create the directories here;

#mkdir classes && mkdir lib

We now need to create a package for our Application. Lets call it org.red5.webapps.red5java#cd src#mkdir -p org/red5/webapps/red5java

Your sources will go into the org/red5/webapps/red5java directory.

[*TODO: Verify and test the statement below*] red5java represents your application scope underthe global scope ie webapps. Sub-folders under red5java would represent your room scope ie allsubfolders under red5java are subscopes of the red5java application scope.

If you are on Windows, you can create your directory structure from within eclipse, so that it willlook something like this. After you create the src directory, under WEB-INF, right click src directorythen New>Package and create a package so that it has the structure shown below (Dont worry, sinceyou are downloading the sources, these folders are already created for you):

> |red5_server - -> |webapps - -> |red5java - -> |WEB-INF - -> |src



- -> |your - -> |package - -> |name - -> |classes - -> |lib

The build.xml file that came with the sources can prepare the classes and lib directories for you,simply type:

#ant prepare

To clean out directories after a build, type:

#ant clean

You can change the target of your build by editing the source and target tags. For 1.6, change from1.5 to 1.6.

Now, for the concept:If you created a new application (as we will later) eg MYAPPLICATION, your directory structurewould look more or less look like this:

> |red5_server - -> |webapps - -> |MYAPPLICATION - -> |WEB-INF - -> |src - -> |your - -> |package - -> |name - -> |classes - -> |lib

3. Let us now study the following files which are contained within the WEB-INF folder: web.xml,red5-web.xml, red5-web.properties, log4j.properties, build.xml. These files are ordinarily dropped inthe WEB-INF folder:red5_server > webapps > red5java > WEB-INF > drop them here!:

a) web.xml: This is the first file that your Jetty/Tomcat Servlet engine will read. The parameterwebAppRootKey defines the application context of your application. This file required by theservelet specification and is the standard deployment descriptor used by your Servlet engine. It willbe used to load the other 3 files below. Again consult Joachims migration guide.

b) red5-web.xml: This config file is used to configure and load your scope/context handler, yourvirtual-host configuration and your very own application. This is file is used by the SpringFramework IoC beans when Dependency Injecting your Servlet so it can be correctly instantiatedwithin the red5 server.It is also within this file that you configure your Handlers. The Handlers are the methods that arecalled when a flash client connects to your application ie rtmp://your-ip/your-application. your-application represents an application scope and so these Handler/Methods are valid within your



application scope. Thus, your Handlers will be able to react when a flash client connects or leavesyour application scope, you need to implement the interface org.red5.server.api.IScopeHandler.Joachim Bauchs tutorial explains this in good detail:HOWTO-NewApplications.txtThe Dependency Injection specified by the bean id web.handler is very important or else yourapplication might not start. Please ensure you specify the correct classpath of your application here.

c) red5-web.properties: This file is imported into the red5-web.xml file. Use this file for items thatoften change within your configuration eg the contextPath (ie name of your application scope) orvirtualHosts directives (which might change from one hosted service to another). If you open the filered5-web.xml, you will see that the Spring PropertyPlaceholderConfigurer bean is used to load thered5.properties file. The contextPath and virtualHosts properties are loaded within the red5-web.xmlfile by using the variables ${webapp.contextPath} and ${webapp.virtualHosts} respectively.

d) log4j.properties: This is used to configure the logging properties of your application by usingthe log4j libraries. This file will be used by theorg.apache.commons.logging LogFactory class.

For the settings in this file to take effect, you have to register the logger for your application in thisfile. (Alternatively though, you could add your log4j definition in the conf/log4j.properties file,together with the logging definitions for the other sample Red5 applications. However, you may justuse the log4j.properties file that is within your own application). Add the following entry (modify asappropriate for your own application):

In red5_server/webapps/red5java/WEB-INF/log4j.properties or red5_server/conf/log4j.properties:log4j.logger.org.red5.webapps.red5java=DEBUG

In your class you will retreive the log by using:protected static Log log = \LogFactory.getLog(Application.class.getName());

You can obtain a template of these files from within the red5 server folder by going todoc/templates/myapp/WEB-INF

The combination of the above 4 files is used to instantiate your red5 application. This is theapplication we will be using to communicate with flash clients for this tutorial.

e) build.xml: This is the file that we will use to compile our application before restarting red5. Youmay use this example build file to compile/build for your own custom applications. Modify thefollowing parameters as appropriate:

In our case it was red5java.jar and so we have:

4. Now going back to Eclipse, click within the Naviator Panel and then click F5 to refresh yourNavigator panel. You will now see the folder red5java under webapps. Under red5java is WEB-INFand under WEB-INF is src. The folder src contains the folders that represent your package above ieorg.red5.webapps.red5java

[Please note that all Shared Objects below are "Remote Shared Objects" ie they are stored on theServer, not the flash client]



CREATE A PLAYLIST AND STORE IT WITHIN TRANSIENT RED5 SERVER SHAREDOBJECT USING JAVA AND OTHER SHARED OBJECTS FUNCTIONALITY

In this section we will create a Shared Red5 object. This object represents a Playlist of all availablecontent. Once this playlist has been loaded into the Shared Object, all Flash clients that connect toour red5java application scope will have access to the same playlist. This is because in an idealenvironment, we would only need one playlist for all our Flash clients. This playlist could typicallybe loaded from an XML file (see loadPlayList method of Application.java). But rather than alwaysre-reading the XML file everytime a client connects, this XML could be loaded only once when thefirst client connects and then made immediately available to all other clients when they connect.This is why we put the method appStart(IScope app) hook.[****This is a very important NOTE****: When debugging your application, do not put any codeinside the appStart method unless you are absolutely sure it works. This is because an error in theapplication scope of your application will result in your application never ever even seeing the lightof day. Debug in say appConnect method (so you are able to view related debug logs) and onlytransfer to appStart once you are sure it works.]

1. From your red5java WEB-INF folder, right click and create a new folder called playlist. Inside thisfolder we drop the following file inside this playlist folder: playlist.xml

Now while still within your red5java WEB-INF folder, navigate to

org>red5>server>webapps>red5java>WEB-INF>src>org>red5>webapps>red5java.

The following source java files are dropped in: Application.java, DemoService.java,SOEventListener.java, SOHandler.java, ScheduledJob.java. These are the files that we will use todemonstrate creation of transient/non-persisted shared objects, handlers, listeners and a scheduledjob. Our package name is org.red5.webapps.red5java

Below I explain some aspects of this example red5 application.

2. The Application.java.> Application.java is the scope handler of you application. By extending the ApplicationAdapterclass, we can determine or code what happens whenever the application is started, whenever the anew client connects or disconnects and whenever an application is stopped.

> loadPlayList loads playlist items from an xml file. The main scope of your red5 application will bethe folder of your red5 appliction. In our case, the main scope was therefore red5java. Thus on doingthe following:Resource playlistXML =\ this.appScope.getResource(fileName);

we actually get the resource from red5java/playlist/playlist.xml

We retreive the Inputstream to the xml file by using the usual JAVA BufferedReader.

3. The DemoService.javaThere is no reason we could not have put the methods in this file in the Application.java file.However, we all know that it is good programming practise to separate application logic intodifferent classes depending on the pattern that emerges in your application. Anyway, that wont bethe case for now, I just want to show you something very interesting



Methods in DemoService.java are called from the flex2 client using the following call for example:nc.call("demoService.getPlayList", nc_responder);

Now for the interesting question, how the hell does by flash client get to know how and where to callthe demoservice.getPlayList method from. How does it do this? This is accomplished by wiring yourDemoService class in the red5-web.xml file, through defining its bean in this file. If you have moreclasses, this is exactly the same place you would place them in. Thus, whenever your flash client callsa remote red5 method, the rtmp handler will be able in turn find and call your class due to this beandefinition(**confirm/test this statement). You will also notice that the red5-web.xml file contains abean definition for the Application.java file above; it is defined as the main web handler of yourapplication as described above.Here are the bean definitions we are talking about in the red5-web.xml file:

bean id="web.handler" class="org.red5.webapps.red5java.Application"

and

bean id="demoService.service" class="org.red5.webapps.red5java.DemoService"

The new service you define in red5-web.xml should end with service, so that red5 will be able toinvoke it.

4. You may call getPlayList method that makes use of a "Transient Shared Object" from the flex2application which you can download from here:red5_flexclient.tar.gz

Open the Flash client from the following URL. Put the following URL: rtmp://ip-of-your-red5-server/red5java.

Click the "Connect" button. On connecting to the red5 application from the flash client, thefollowing happens:

>the xml playlist is loaded into a transient shared object, once only during the start of theapplication. To veiw the contents of this shared object, select getPlayList method and click on theExecute button. You will see the contents of the playListSO SharedObject we loaded in the red5server printed on the Text Area. However, this method will only work with the latest trunk of red5.

>a counter of all the persons who have connected to your application scope is printed by clicking onthe Execute button after selecting the getCounter method (This method should work with the latestrelease of red5). Follow this sequence several times to see the counter changing:Connect>select getCounter >click Execute>click Disconnect>click Connect>select getCounter>clickExecute ... etc...

>a transient shared object with a listener is created in the red5 initTSOwithListener() method. Thelistener should be triggered whenever a change occurs to the shared object. To demonstrate this,select the sendMessage(trigger Red5 TSO update) method and click execute. If you go to thered5_server console, you will see the default message "This is to modify TSO" printed, andonSharedObjectUpdate for the SOEventListener triggered. You may change the message that is



sent to red5 by entering your own text, inside the textbox labelled Message(message to send tored5). This textbox can also be used to change the message used to update the persistent sharedobject with listener below. At this point it is very important that I mention that make sure that youput your onSharedObjectUpdate functionality in the

onSharedObjectUpdate \(ISharedObjectBase so, String key, Object value)

and notonSharedObjectUpdate functionality in the

onSharedObjectUpdate \(ISharedObject so, String key, Object value)

or else the onSharedObjectUpdate Event will never be triggered. Please remember this as it is veryeasy to confuse these 2 interface methods.

> a persistent shared object with a listener is created with the initPSOwithListener method, and justlike the transient shared object above, the listener should be triggered everytime there is a changewith the persistent shared object. Again, if you experience problems with this method, delete thered5java/persistence/SharedObjects folder.

> Calling a remote shared object method using remote_sharedobject.send("handler", "args") shouldcause your red5 shared object handler to be called. Shared object handlers can either be defined inred5-web.xml or by defining a Handler class and registering it using the sharedobjectregisterServiceHandler method. Please consult Joachim's guide for a good explanation of this.

>If on the flex client you listen for change events on shared objects, then red5 will enable thissynchronisation for you, so that whenever a sharedobject value changes, the flex client will beinformed. Please refer the red5_flexclient.tar.gz sources for examples of how to do this.

SHARED OBJECT LISTENERS NOTESThese implement the ISharedListener interface.1. You can register several listener classes (which in our case was SOEventListener), for the sameshared object.

2. Several SharedObjects can use the same listener. Simply identify the shared object attributeswhose values are changing by ensuring names (keys to the shared object attributes/values) areunique. React differently if the name returned is different.

SHARED OBJECT HANDLERS NOTES1. You may call a remote shared object from the red5 server by using SharedObject.getRemotesyntax (please see the red5_flexclient sources attached).2. You may call a red5 method (without ever having to register the class in red5-web.xml), by usingso.registerServiceHandler syntax, where you can register a method handler for a shared object (Youmay still do the same using the red5-web.xml file though - see Joachim's migration guide). You thencall this method using the remote_so.send syntax (refer to the red5_flexclient.tar.gz for how to do so)

SCHEDULE FOR THE PLAYLIST TO BE RELOADED EVERY 1 HOUR USING JAVAYou might want the playlist Transient shared object above to be reloaded every 10 minutes withupdated content from a changing playlist.xml file. The Application.java and ScheduledJob.java filesshows you how to create a regularly scheduled job.



BUILD YOUR RED5 APPLICATIONWhenever you make a change to your application, you need to rebuild it and restart red5. Using thered5java build file provided, here's an example that allows you to automate and speed up thisprocess using ant:

1. First create red5.jar by running from within the root/base of the red5 source folder. You only needto do this once (ie just after downloading red5), and not all the time.

#ant jar

2. Now go to the red5java directory within your webapps directory and do:#ant build

To adapt the build.xml file for yourself, simply change the following build.xml items depending onyour system:>target.jar (put the name of your own jar file)>source= (put 1.5 or 1.6 depending on the java jvm version you are running on your machine)>target= (put 1.5 or 1.6 depending on the java jvm version you are running on your machine)

3. If your application builds successfully, restart red5 using ant server, ./red5.sh or red5.bat and thentry to connect to your red5 application using the sample flex2 application you have modified.

CONCLUSIONThe code written here is by no means clean and is not designed using the best principles. Most of itwas written while half-asleep . It is only meant as a guide so you are able to see Red5 in action byexample based on Joachim's Migration Guide. In addition, this code has been little tested andtherefore comes with no warranty whatsoever.

February 7, 2007 @ 11:25 pmHi there, this is very impressive and I cant wait to integrate Red 5 into my site. Ive looked atmany sites and tutorials, but cant figure out one thing. I want to be able to add charactervalidation function when users log into the chatroom. Can you prescribe methods of achievingthis? Thanks

February 8, 2007 @ 11:30 pmHi Bobby, Thanks.I would probably add the character validation methods on the flash client side rather than serverside. The server side just acts as a passage way for the chat messages.

Connection:RejectedConnection:Closed

and when i check the log of the Red5 Server , then it tells me this

No Scope myapp found on localhost.

March 7, 2007 @ 6:05 pmHi Alan,

The reason the jar file isnt created is because it is not the default target of the ant build file. Youneed to run off the shell/command prompt:>ant jarFor the jar file to be created.Have you tried downloading the flexclient code that comes with this tutorial? It will connect tothe red5java application scope ok.

March 27, 2007 @ 11:20 pmHi Omar,You need to use something like:

import org.red5.server.api.service.IServiceCapableConnection;

IServiceCapableConnection service = (IServiceCapableConnection) conn;service.invoke(setId, new Object[] { conn.getClient().getId() }, this);

Where setID would be a public function on your flash client. Object[] array will contain all theparameters of your flash function. If I remember well,a good example is in fitcDemosApplication.java

April 21, 2007 @ 11:42 amSo I decided to take matters into my own hands. I downloaded the Flex2 SDK, lobbed the Flexclient into the Flex2 samples directory and after checking the names of all directories werecorrect I ran ant to build the Flex client.

I got the build error:BUILD FAILEDE:\Flex2\samples\red5_flexclient\build.xml:29: Execute failed: java.io.IOException:



CreateProcess: E:\Flex2\bin\mxmlc -default-frame-rate=30 -incremental=true -default-background-color=0x869CA7 -default-size 900 650E:\Flex2\samples\red5_flexclient/src/main.mxml -o=E:\Flex2\samples\red5_flexclient/bin/main.swf error=193

So undaunted I ran the mxmlc compiler command directly from the command line and itworked the client was successfully rebuilt! Would just like to know why that ant build isfailing.

July 20, 2007 @ 11:08 amHello Sreenivas,

Sorry for taking so long to get back to you. I havent tried this yet but probably go to your red5server directory and do an#ant warGrub the created war and drop it inside the tomcat webapps directory. Will try this out thisweekend and report on the exact steps.

#ant webwar

Thank you for this great tutorial, pretty valuable for a flex / red5 beginner.



Thank you for this great tutorial, pretty valuable for a flex / red5 beginner.Everything works as expected, but im having troubles calling the remote shared object handlermethod from Flex,

- When first connected, calling TSOHandler.sendMessage(..) from Flex gets registered in red5log, but tsoOnSync event handler never gets called in Flex.

- If I disconnect from the server and reconnect, subsequent calls dont even get logged in Red5.

Everything goes fine by using NetConnection.call instead. Any clue about this?

Is there any performance penalty for using the NetConnection call method instead of theSharedObject method?

Thanks in advance

September 16, 2007 @ 8:07 pmHi,

Seems the second issue has been solved in Red5 trunk. The room scope was not being stoppedwhen the last client exited the room although my shared object was being properly freed. Since iwas creating this shared object at roomStart handler which was never fired again -since fromservers point of view the room actually was running-, i was getting a null reference to the SO.Now its (apparently) fixed.

First issues still driving me mad.

Thank you.

December 5, 2007 @ 8:03 pmHey jwamicha, I think you accidentally left something out that you meant to include (and itsthe very thing that I am looking for).

In this part:

e) build.xml: This is the file that we will use to compile our application before restarting red5.You may use this example build file to compile/build for your own custom applications. Modifythe following parameters as appropriate:

In our case it was red5java.jar and so we have:

There is nothing after the two colons. (And then it just goes on to the next topic). I even checkedthe underlying html and there are just empty code tags (as if you were going to paste it in there).That code is what I need. Can you please fill in these two empty spaces? Thanks so much.

August 20, 2008 @ 5:36 amI have two problems

1) For this tutorial, I cant get the client to connect to the server.> Connection to rtmp://localhost/red5java closed.

2) However, I have been able to connect with the simple demo example (which adds twonumbers). The problem is that it never returns the sum.

Im using red5 0.7, Ubuntu 8.04. Java 1.6.0.Note: I can get the SOSample to work. Also I am restarting red5 whenever I make modificationsto red5java.

October 17, 2008 @ 1:36 pmHi,

I ran into the same problem Varley described. I can not connect to the red5 server. In the flexGUI I get the message:

Connection to rtmp://localhost/red5java closed.

and in my red5 error log I find:

2008-10-17 12:29:58,648 [DefaultQuartzScheduler_Worker-1] WARNo.r.server.net.rtmp.RTMPConnection Closing RTMPMinaConnection from 127.0.0.1 : 33247 tolocalhost (in: 3467 out 3215 ), with id 3784466 due to long handshake

I use Red5 0.7 on Slackware 10.1 with JDK 1.6.

I saw these kind of problem before with the demos from red5 installation. Here I needed to installthe single demos using the link on the start page of red5. After that installation the demosworked (see current red5 FAQ).

Any idea?

November 3, 2008 @ 4:25 pmOn my second try or view I must say a great tutorial,that shows many of the great features of red5.

I tried several versions from red5, but I only had success with red5-0.6.3.So I recommend to use this version with this tutorial.

My final successful environment:



My final successful environment:Client (Windows XP SP3)- Flex Builder 3 (60 Trial from Adobe)Server (Slackware Linux 2.4.29)- Red5 V0.6.3 (build with ant)

November 14, 2008 @ 6:20 pmCurrent situation:I know action script 2 and other animation technique of Flash.Red5 has been installed on the server. I can access to this server using IP Addressxxx.xxx.xxx.xxx. The person who installed the red5, said that it is installed on /user/local/red. Ialso have hosted other domains on the server.Now I need to know the following things:Set A:1. What is the root folder of my red5 server (e.g. public_html or httpdocs etc)?2. How can I access to my root folders files (flv) from any internet browser?3. Can I access on the server from my other domains? If yes, How? (e.g. rtmp://mydomain.com).

Set B:What are the alternatives of $_POST and $_GET of PHP in action script? I mean, I want to passthe data from php to swf.I may use $_GET type data (mysite.com/index.php?myvariable=123), or post data of a form.By the same way, I want to post the data from swf file to php by using any method. How can I?

You have to provide me answers of these questions in a simple way so that I can understandand with example codes.

April 20, 2009 @ 4:04 pmHi Joseph,

Thanks for the tutorial. One question, quite easy to stream from file directory(/streams) but is itpossible to stream a flv not from custom/directory(streams) but from db directly lets say MySQLBlob object.Also is it possible to stream a video straight into VideoDisplay object usingBlazeDS+Tomcat+Java+Flex rather than using HttpService call?

Thanks again for this great article.

If you can help me fix this up, I would be grateful. I havent looked at red5 in very long.Thanks Poon.

Ive also been putting this off for too long; Ill take a thorough look at the current red5 release(the red5 team have been tireless and have done an excellent dev job on red5 with many newfeatures since this tutorial was made) and update this tutorial with anything new I may find,in the coming weeks.

July 12, 2009 @ 7:46 amHere is an updated version of red4java code that compiles and runs on latest Red5 0.8.0trunk code (rev 3700). Not all client functionalities are working jet. I also notice somestrange behavior.

You can download the updated code here:http://public-misc.s3.amazonaws.com/red5java-20090711.zip

The changes are as follow:

Since Red5 0.7.0, Red5 switched from log4j to slf4j. I decide to stay with Red5 nativelogger instead of using a separate logger.

As a result, all loggers instantiation code in *.java has to be changed. In addition, alllogger config in *.xml are also updated.

Ant build file is updated to use the new logger jar file. In addition, the scripts.propertiesand lib.properties in Red5 6.x are no longer there.

February 4, 2010 @ 2:21 pmHi!

Thanks for your post. Its been helpful BUT with every application that I try to create oreven already created sample applications (including yours), I get the same error when startingthe server. EVERYTIME!!!!This is the error I get:Exception in thread Launcher:/videoDemo java.lang.RuntimeException: Failed to loadwebapplication context class.at org.red5.server.tomcat.TomcatLoader$1.run(TomcatLoader.java:531)Caused by: java.lang.ClassNotFoundException:org/springframework/web/context/support/XmlWebApplicationContextat java.lang.Class.forName0(Native Method)at java.lang.Class.forName(Class.java:247)at org.red5.server.tomcat.TomcatLoader$1.run(TomcatLoader.java:528)

Since I get the same error for every application, Im guessing the problem is more with myconfiguration of the server or something, as opposed to a xml files problems.

CAN YOU PLEASE PLEASE HELP ME?!?!? Im desperate!!!!

Thank you!

and

solved the problem and allowed me to run my application. I hope this helps.

June 16, 2010 @ 9:51 pmHello,

I found this guild while trying to get the red5recorder (simple red5 flash application that canrecord from a video camera to the server) working. I dont see anything called WEB-INF in hisdownload zip. I see he also charges 400 pounds for an install which is probably a 5 minute deal ifthere were any kind of install instructions or documentation.

Is this guy trying to lead everyone off the path to get everything working? Ive never addedanything flash into my site a couple days ago.

Im looking to go though your setup process on his source package, which seems to be missingthe server configuration files.

I was wondering if you had installed red5recorder before, and if you and any tips for someonejust starting out, or even if you could point me in the right direction.

Thanks!-Chris

Hi Chris,

Its been about 2 years since I last used red5. You would need to compile thered5recorder.mxml (and maybe BlinkApp.mxml?) into an .swf file for the website. You couldtry using ant and the build.xml file in red5_flexclient for a build example. Good luck!
