Hi, according to the table [here](https://www.wowza.com/docs/how-to-configure-closed-captioning-for-live-streaming#transtable) you can take CEA 608 input and have WebVTT output, but nothing in the guide seems to specify how to do that. I’m assuming I need to enable the properties for ingesting cea 608, but then the property for creating webvtt captions, cupertinoLiveCaptionsUseWebVTT, specifically says in the tooltip that it is for converting from onTextData captions. Will that also work in converting from CEA 608 captions, or is there another way to accomplish this?

Can anybody answer this? Because the only option I see is to convert OnText data to WebVTT and not CEA-608?

I’ve tried this module and then to enable WebVTT but not sure it does anything.

Hi Matthew,

Thanks for using our forums.

The following article describes how to take onTextData and send the captions as WebVTT for iOS devices:

[https://www.wowza.com/docs/how-to-stream-webvtt-subtitles-to-ios-for-closed-captioning#live](https://www.wowza.com/docs/how-to-stream-webvtt-subtitles-to-ios-for-closed-captioning#live)

To take the CEA-608 captions in your live stream and ingest and convert them to onTextData please follow the instructions in the following article:  
[https://www.wowza.com/docs/how-to-configure-closed-captioning-for-live-streaming#cea608](https://www.wowza.com/docs/how-to-configure-closed-captioning-for-live-streaming#cea608)

Hope this helps,

Alex
