Can not get netgroup list in smil file

Wowza Streaming Engine
1

Hello,

I have setuped a default transcoder template with a group all.

The source and the 160p incoming streams are available (and tested with the test player).

When I try to acces to http://${wowza_ip}:1935/live/ngrp:${SourceStreamName}_all/jwplayer.smil, nothing is returned and I’m getting this error in the logs :

HTTPProviderMediaList.onHTTPRequest: MediaList not found: live/_definst_/ngrp:${SourceStreamName}_all

Do you know what could be wrong ?

I have a developer license of Wowza server 4.2.0 with Transcoder addon activated (no specific license for that addon), could it be a reason (eg. https://www.wowza.com/forums/showthread.php?32549-Transcoder-Addon-Problem).

Thanks in advance.

Here is the configuration file extract :

Hi,

Is your live stream published and the transcoding process started at the time you are trying to access the Stream Name Group?

Can you access each of the transcoded output streams individually? (yourStreamName_source and yourStreamName_160p)

Thanks for the update, glad to hear this is working for you now.

Hello,

The transocding process started when I tried to access the Stream Name Group.

I can access to each of the transcoded incoming stream via the integrated test player (Adobe RTMP for example). Both yourStreamName_source and yourStreamName_160p are working is the test player.

Thanks
