I’m trying to make a module for manifest manipulation, specifically - to simulate live streaming. I made module, following tutorial, made separate class:

public class DvrStartDurationPlaylistRequestDelegate extends DvrBasePlaylistRequestDelegate

Question is: do I need to add my class name into Application.xml?

dvrPlaylistRequestDelegate com.prometheantv.wowza.DvrStartDurationPlaylistRequestDelegate

I also have my module referenced in Application.xml

vod2live

vod to live simulation com.prometheantv.wowza.vod2live

Thank you in advance.

Igor

Looks like Wowza is not taking parameters in Application XML for DVR section
