More version details

This error from the previous GIT was never fixed - ExoPlayer still can't correctly detect & play 608/708 embedded captions (but every other major set top box player video player can by default) - is there an updated way in ExoPlayer 3 to get this working?

Amazon Support just verified the issue running the demo app and pointed us to the never closed ticket: https://github.com/google/ExoPlayer/issues/8130

It's impossible to say for sure without access to your media, but this is likely because the HLS multivariant playlist doesn't contain any CLOSED-CAPTIONS information, meaning ExoPlayer does not know to look for captions in the video files. The best approach is to fix your playlist to correctly declare its contents. If that's not possible, you can try disabling chunkless preparation, that may result in ExoPlayer reporting that every video file has 'unknown' captions:

I'll take a look at the playlist and see if I can post a munged version. But I have to ask, how does Video.js, VLC, Apple default player, Roku Default player, every broadcast television player we distribute to now find and show the two live 608/708 embedded captions fine and display them without issues.

Why is ExoPlayer the only one that cannot?
