How can i display WebVTT Closed Captions on my custom roVideoPlayer? I Have m3u8 HLS Live stream with included webvtt subtitles in manifest.

I read it:

1. https://sdkdocs.roku.com/display/sdkdoc/Closed+Caption+Support


2. https://blog.roku.com/developer/2014/01/16/new-closed-caption-features-for-brightscript-developers/

But it doesn't work. subtitles still didn't shown. roCaptionRendererEvent never occurs.

Please send stream URL with webVTT we can test to developer (at) roku.com

Thanks,

Joel

While it's unlikely you're still hung up on this problem, I want to leave this working example here for anyone else who may run into the same issue.

All examples with webVTT subtitles requires stream track number. It's variable information in our streams (sometimes 1, sometimes 9, etc.), can i ignore it in my code?

For example from doc:

subtitle_config = {
TrackName: 
"webvtt/9"
}

For example from andyy's code:

TrackIDSubtitle: "webvtt/1" ' TrackIDSubtitle property should be set to webvtt/track, where track specifies the index of the caption track to render

etc...

Just wondering is there a way of setting a webvtt url as subtitle instead of embed it in the HLS stream?
