Support HDR playback

[Exaphis]

HDR quality levels currently do not show up when sideloaded.

This is because window.MediaSource.isTypeSupported returns false for VP9 profile 2 MIME types. Even if I override this, the video simply does not play.

This is likely an entitlement issue and is unlikely a problem you can solve.
From my understanding, Apple likes to hand out (sometimes undocumented) special entitlements to companies like Google [1], [2].

Wouldn't be surprised if there's a similar situation here.

Agreed, that was my assessment as well.

@PoomSmart's YTUHD falls back to software VP9– I wonder if that is also present in the Apple TV version?

Hey, recently installed mutube and love it. But curious if there’s any update on the progress with getting HDR working?
