Custom parameters readout for ngrp stream from Wowza


I am live streaming product trailers and preview videos interrupted by actual live broadcasts all via an ngrp abr stream with streamschedule smil from wowza.

I need two parameters that I can use to show the title and the price of the product that is currently being shown in the stream. One flag (could be 0 or 1) that determines whether the stream is truly live or whether it is a rebroadcast. The second is a simple max 5 digit integer that reveals the product code.

I could even combine these two into one code where I just strip the first character to know whether the current stream is really live or a rebroadcast and the rest then is the product code.

Does anyone know the easiest way to get this variable code into the client side from wowza to jwplayer? I was referred to injecting cuepoints into the stream. I can't get the grasp of how I can get that to work, but it also seems an awful lot of work and a complicated workflow for just one simple integer variable.

Many thanks in advance for any help you can give.

By the way I'm running (was probably obvious) the Wowza transcoder that transrates video files via a live application and that will be interrupted by a real live stream every now and then.

Thanks for any help

I believe this can be done by using ID3 metadata in HLS streams. I would consult with Wowza to see how this can be configure on that end. Once you have this configured, you will be able to read ID3 data that comes through the `onMeta` event handler in our player API:
