Error creating bean with name 'streamFilenameGenerator'

[Andreas We]

Hello,

Red5 1.0

Java 1.7

my code:

package org.red5.core;

import org.red5.server.api.scope.IScope;

import org.red5.server.api.stream.IStreamFilenameGenerator;

public abstract class FNG implements IStreamFilenameGenerator {

        public String recordPath = "/";

     

        public String playbackPath = "/";

        

        public String generateFilename(IScope scope, String name,

                GenerationType type) {

            

            return generateFilename(scope, name, null, type);

        }

        public String generateFilename(IScope scope, String name,

                String extension, GenerationType type) {

            String filename;

            if (type == GenerationType.RECORD)

                filename = recordPath + name;

            else

                filename = playbackPath + name;

            

            if (extension != null)

                

                filename += extension;

            System.out.println("FILE: " + filename);

            return filename;

        }

    }

thank you!

The answer seems to be in the stack trace: your class is abstract and cannot be instantiated.

On a different note, I am not sure your class should belong to org.red5.core as that package is really for server classes.

Cheers,
Luigi

your class is marked 'abstract' hence the InstantiationException.

It can't be created!

Hi,

public  class FNG implements IStreamFilenameGenerator {

then eclipse says:

Hello,

ok, its my first time, that i work with red5 :-)

it works now, i just add

 public boolean resolvesToAbsolutePath() {

            return false;

        }

thank you!

One question more:

my code:

public  class FNG implements IStreamFilenameGenerator {

    public String generateFilename(IScope scope, String name, GenerationType type) {

            return generateFilename(scope, name, null, type);

        }

        @Override

        public String generateFilename(IScope scope, String name, String extension, GenerationType type) {

        String fn;

        if (type == GenerationType.RECORD) { 

        System.out.println("Camera Connect  " + name); 

        fn = name; 

        } else {

        System.out.println("Viewer Connect  " + name); 

        fn = "test.flv"; } 

            return fn;

        }

        @Override

        public boolean resolvesToAbsolutePath() {

            return false;

        }

    }

if connect the publisher strean name: test.flv 

log:

Camera Connect  test.flv

[INFO] [NioProcessor-2] org.red5.core.Application - W3C x-category:stream x-event:publish c-ip:0:0:0:0:0:0:0:1 x-sname:148fe662-a44a-470e-b5ae-bf091c32125c x-name:test.flv

Then i try to connect with a viewer:

how i fix that?

Thanks

I only work with that set of classes every so often so I do forget the exact routines; I would suggest saving this url while you're learning the server: http://red5.googlecode.com/svn/doc/trunk/reference/html/index.html

To jump specifically to the filename gen / stream stuff, go here:

It works fine with static files on disk,  but i want to use it with  live streams!

i have 8 TV channels from satelite receiver, i send it to the server ch1, ch2, ch3.... and sometimes i need that all users see only one channel.

in this case i want that all connections and streamnames goes to one livestream! 

If the user request StreamFooBar123 he has to get stream channel1...or so..  like the apache mod_rewrite :-)

it looks like,  generateFilename() works only with real files, not with broadcast stream

[Mondain]

For live streams you're going to want ServerStream or StreamService; I believe one of those has a look-up. Also be aware that you can supply parameters on the client side application to force "live" or "recorded". Have a look at this: http://livedocs.adobe.com/flashmediaserver/3.0/hpdocs/help.html?content=00000185.html
