Hello Yung, welcome to the Wowza support forum.

This looks like you may have a malformed .xml file. Please double check for any typos or misspellings.

Also you can check against an XML validator:

Kind regards,

Dear Salvadore,

Thank you for your suggestion!

I am facing the problem on redirect client from origin to edges, I followed the manual to add an redirect application from the manager and edit Application.xml file to add Module. But seems it is not working, I have an application “live” and “redirect” in origin server, “edge” in edges server.

Encoder FMS URL is: rtmp:///live

StreamName: teststream

Flash player is: rtmp:///redirect/live

StreamName: teststream

No problem on pushing streaming from encder to wowza, but flash player cannot play the rtmp I set.

If:

Flash player is: rtmp:///redirect

StreamName: teststream

Error from Origin:

ERROR server comment 2014-10-30 16:25:38 - - - - - 5051.2 - - MediaStream.onUnPublish[redirect/hennessyOrigin/teststream] : java.lang.NullPointerException|at com.wowza.wms.plugin.loadbalancer.redirect.ClientConnections$StreamListener.onUnPublish(ClientConnections.java:329)|at com.wowza.wms.stream.MediaStream.notifyActionUnPublish(MediaStream.java:2386)|at com.wowza.wms.client.Client.closeOpenStream(Client.java:1718)|at com.wowza.wms.module.ModuleCore.closeStream(ModuleCore.java:785)|at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)|

Am I correct on the setting?

Dear Zoran,

I am using rtmp://:1935/live/teststream and it can play. But not for rtmp://:1935/redirect/live/teststream

I am using flowplayer, seems it is not able to redirect. Now I am trying to use RTMP XML, however, I got the smil file but no idea how to work further. Would you please suggest me how can I loadbalance the connection from the smil file? Thank you very much!

BR,

Yung

Wai_Cheung_Yung · October 31, 2014, 4:46pm

Dear All,

Problem has been fixed by using flowplayer and smil to perform the live streaming with loadbalancing. Thx for the effort!

BR,

Yung

Wai_Cheung_Yung · November 4, 2014, 11:08am

Dear Zoran,

Sure!

Actually, I use rtmp://// in Encoder,

http://:1935/redirect// is the SMIL file contains LB server information,

then use http://flash.flowplayer.org/plugins/streaming/smil.html as the player.

However, I found the developer key will have problem on getting LB server information as it will show “No Load Balanced servers available” after awhile. Change it to daily keep will able to keep the server connection between origin and edges. Not sure if the problem only happened to me… Anyway, it works fine now.

BR,

Yung

Zoran · October 30, 2014, 1:05pm

Hi,

Just to make sure that your loadbalancing is setup correctly, are you able to play back the following RTSP stream using VLC player?

rtsp://<Origin IP>:1935/redirect/live/teststream

What Flash player are you using for playback. Does it support the redirect NetConnection call?

Zoran

Zoran · November 2, 2014, 10:10am

Great. Thank you for the update.

Can you also post a description on how yo managed to fix you issue so other forum users could benefit from your experience?

Zoran
