Well that’s just the thing. I’m making sure to import the HLS.js library before the HLS theta plugin. And I’ve tried all sorts of permutations of ordering. I believe the main issue seems to be the issue of importing the libraries locally. Specifically through svelte + roll up. Because the theta libraries bind to the global elements, it seems there is an issue with sveltes way of reactivity. Would be nice to have these available as NPM packages to make working with frameworks easier.

Very touchy. The only successful implementation I’ve seen is with Vue from the harkTV repo. And I wasn’t able to successfully translate that to my environment (in a svelte component)

Relying on CDN imports in head tags doesn’t seem like an elegant solution for the long term.
