Query server status from outside
by Thomas-128

Rate this Message:
Hi,
After presenting my website, it appeared that my application doesn't inform the users about visiconferences being currently broadcasted or not, so people just see a blank page if nobody is in the room, and it feels like my app is not working properly. Therefore I'd like my Ruby on Rails application to be able to query red5 about a stream being broadcasted or not. I would simply issue a query using http like: "is user_id broadcasting?" and red5 would simply answer "true/false". How do do that? -- VOD & visioconference - http://www.digiprof.tv _______________________________________________ Red5 mailing list Red5@... http://osflash.org/mailman/listinfo/red5_osflash.org |

create a servlet that can be called from your application. The servlet just needs to grab the applicationContext which can then be used to resolve scopes. Once you've got a listing of your scopes, you can grab the connections/clients or whatever you need.

Hi,
I tried following the example: http://red5.org/wiki/Examples/FileUploadServlet But I can manage to correctly setup my servlet. The amount of xml garbage required by tomcat is just daunting me. Does anyone have a code example for a red5 app with a simple HelloWorld servlet? I'm specially interested in the configuration file.

Cool I got it working! I had to add the application name in the url.
Now I need to be able to hook myself to red5 and fetch the list of currently published streams. -- VOD & visioconference - http://www.digiprof.tv _______________________________________________ Red5 mailing list Red5@... http://osflash.org/mailman/listinfo/red5_osflash.org |

If i have time later i'll post how to get the stream names, but for now I would like to point out that if you were using an IDE with code completion you would see that your statement is false. The ApplicationContext does have the method getBean, as shown in the spring docs
The samples are not perfect but they have helped thousands of people find their way so you may want to look a little deeper and do some testing before saying they are "unusable".

Hey Thomas...
I don't know if I'm correct..maybe Paul can give to us a hint :D But if you look into the class StreamUtils there's a method to get stream by name... inside there's an Map all streams maybe created with this class... I guess you can extended and create a method to return the Map with all streams... no t sure it works... Another option, maybe the right one ;) it apparently looks good to me...I'll try it when I have time...(just got back from weekend and trying to get up to date with all stuff..) IServerStream stream = StreamUtils.getServerStream(appScope, this.name); You can try this: IProviderService providerService = (IProviderService) appScope.getContext().getBean(IProviderService.BEAN_NAME); List streams = providerService.getBroadcastStreamNames(appScope); BR Hugo On Sun, Nov 1, 2009 at 6:02 PM, Mondain <mondain@...> wrote: > If i have time later i'll post how to get the stream names, but for now I > would like to point out that if you were using an IDE with code completion > you would see that your statement is false.

How did you want me to guess that the **** programer was missing basic java
know-how. As easy as it is to make the most complex frameworks talk for the RIA's we make, it takes a HUGE body of experience and what is missong in that body must be made up with equal amounts of patience. To make simple servlet, add this to web.xml You need two things, a name and mapping element. And of course to write the class and compile/deploy it. Once done you can hit it like a regular webpage. http://localhost:5080/jservlets/webauth <servlet> <servlet-name>javex</servlet-name> <description>Test</description> <servlet-class>com.domain.servlet.yourName</servlet-class> </servlet> <servlet-mapping> <servlet-name>javex</servlet-name> <url-pattern>/webauth</url-pattern> </servlet-mapping> then make your servlet handler and extend HttpServlet. package com.domain.servlet; public class yourName extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // System.out.println(request.getContextPath()); ApplicationContext appCtx = (ApplicationContext) WebApplicationContextUtils.getWebApplicationContext(request .getSession().getServletContext()); Application app = (Application) appCtx.getBean("web.handler"); response.getOutputStream().write("Red5".getBytes()); } } ----- Original Message ----- From: "Thomas" <iamkenzo@...> To: <red5@...> Sent: Sunday, November 01, 2009 10:16 AM Subject: Re: [Red5] Query server status from outside > On Sun, Nov 1, 2009 at 7:02 PM, Mondain <mondain@...> wrote: >> If i have time later i'll post how to get the stream names, but for now I >> would like to point out that if you were using an IDE with code >> completion >> you would see that your statement is false.

That (almost) same code put inside ApplicationAdapter#streamSubscriberStart works and displays the list of currently available stream names. But outside ApplicationAdapter, it misses something.

Should read:
> List<String> streams = app.getBroadcastStreamNames(); But now I'm having a problem, I need to provide a scope which I don't have within my servlet. So I thought of using RTMPClient to connect as a special client to query the application. But the docs at http://dl.fancycode.com/red5/api/org/red5/server/net/rtmp/RTMPClient.html are really weak. What's the server argument? A string, great. What do I put in it? It doesn't say. I think I got it more or less working, but when connecting, I'd like to specify a room name, but I didn't understand how to do that. On the red5 app side, it seems to create a null room and it doesn't like it. -- VOD & visioconference - http://www.digiprof.tv _______________________________________________ Red5 mailing list Red5@... http://osflash.org/mailman/listinfo/red5_osflash.org |

i don't know what your trying to do...
yes... with RTMPClient you have to specify connection parameters for the application... Client String host = "localhost"; String app = "oflaDemo"; int port = 1935; public MyRTMPClient() { super(); log.debug("connecting, host: " + host + ", app: " + app + ", port: " + port); connect(host, port, app, this); log.debug("connection done."); } I think that the scope is only available on the red5 application...I don't know any way for the client obtain it because scope is registered on Application start on the server part... I'm not an expert too :D I guess that your client can connect to the red5 application and make a call to a method on that application that retrieves to your client what you want...in this case the list of streams.... in a client / server fashion...

Hi hugo,
You are missing a room name (or scope, well whatever name you call it); and connection args, the ones you get back in appConnect as the "Object[] params" argument. I am following Dominick's advise, but I don't know how to resolve scopes from my application_context object.
