Any update on this PR on when this will be merged, as I am having the same issue with videoJS8?

This isn't sufficient yet for Video.js 8 compatibility. The same issue mentioned before will need to be addressed. The build needs to not transpire ES6 classes. This will likely need updates to several dependencies.

Okay @mister-ben . Let me try by updating videojs-generate-rollup-config version.
