We are having an issue with closed captions, its a little bit odd to explain. We can’t seem to enable them until they have started in the video play-back. And then sometimes, they flicker on and off, nothing do with the timing in the CC file? We are using the native HTML5 video play object from the browser. Anyone have any thoughts? Thanks in advance.
I would verify the m3u8 URL signals captions in the stream.
You could also compare with another player’s behavior. Native HTML5 browser playback is often not as robust as a video player. Wowza Flowplayer or hls.js are good candidates. Also check out philcluff dot co dot uk which hosts a variety of players you can use to compare behavior.

Thanks Scott! How do I verify the m3u8 URL signals captions are in the stream?
Also, we have a unique environment, where we are closed to the outside world, and our content is user provided/collected. Hosting a Wowza Flowplayer in a “closed to the Internet environment” is not possible to my knowledge? We will definitely look at few of these open source options to check if they are viable. In regards to close caption configurations, we simply have them enabled, and make sure the extension provided matches our list of supported formats. Pretty simple, unless we are missing something?
If you curl the m3u8, besides audio and video, you will see a SUBTITLES track in the response
No idea if flowplayer allows you to self-host the player. If it was me, I would look at hls.js as an alternative
