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?
