Closed captioning a live stream for a private Roku channel.

Our university uses the Wowza Streaming Engine 4.(?) and an EEG HD-491 closed caption encoder for live streaming. I am not the Wowza admin, but I have been tasked with creating a private Roku channel for live streaming of our graduation ceremonies. Everything on the Roku channel appears to be working except the closed captioning. I am not sure what CEA-608 subtitle track I should choose to display the captions from the Wowza on the Roku channel. According to the Wowza CC tutorial, if the ingested CEA-608 track number to the Wowza is not specified, the track defaults to 99. Is this true of the output as well? If not, is there a way to find what the CEA-608 subtitle/captioning track for the output of the Wowza is without resorting to trial and error?

Hello,

It should default on 99 on the output as well if not specified.

It can be set within the ModuleCEA608ToOnTextData module:
