Where to add the property mpegdashEnableHbbtvLiveProfile?

Wowza Streaming Engine

Hi,

the release of Wowza Streaming Engine 4.1.0 added support for enabling the HbbTV-specific live MPEG-DASH manifest profile definition using the mpegdashEnableHbbtvLiveProfile property.

Where should I add the property mpegdashEnableHbbtvLiveProfile for Application e.g. with name “foo”?

  1. WowzaStreamingEngine-4.8.5/conf/Server.xml
  2. WowzaStreamingEngine-4.8.5/conf/foo/Application.xml

My findings so far:

The entry has to be inside the Element of

WowzaStreamingEngine-4.8.5/conf/foo/Application.xml:

You can do the same in the web-GUI:

Applications > foo: Properties > Custom > Path: /Root/Application/LiveStreamPacketizer

This changes the profile in the manifest.mpd

profiles="urn:hbbtv:dash:profile:isoff-live:2011"

Although E.2.1 of the Technical Specification for Hybrid Broadcast Broadband TV with the HbbTV 1.5 Addons (ETSI TS 102 796 V1.2.1) defines a different profile:

 urn:hbbtv:dash:profile:isoff-live:2012

2011 is also supported since V1.4.1.

But one issue is that of E.2.3 (of V1.2.1) .

In the the attribute scanType is missing. This causes an error when you run the .mpd through the DASH Industry Forum Conformance Tool.

Hi,

I’m trying to set the profile 2012, but it’s not clear to me how to do it.
I

path is ok, but on name attribute what do I have to set?
I tried “profiles” and on value “urn:hbbtv:dash:profile:isoff-live:2012” but it doesn’t work (I still get 2011 profile, I restored the application).

Could you help me?
Kind regards,
Dave
