Sadly this doesn't appear to be maintained any longer. hls.js is only version 0.8.2 instead of the current 1.4.12
None of Apples example streams worked, so I guess this add-on is broken (I only tested Nightly 120)
https://developer.apple.com/streaming/examples/

doesn't work

recent update broke functionality. hls-js got downgraded for 0.8.5 to 0.8.2 ??? Fix please, thanks

Any timeline for a fix?
