(at least) Chromium (if not WebKit in general) based browser (94+) support it.

Did you test this? If so, how?

Why closed??

Please read the previous comment.

Ah, my bad. It didn't show the comment immediately (probably a few sec github action offset between steps).

Anyway. Better to do a PR myself or is the report just fine?

That page doesn't mention VideoTrackGenerator, and the collector tests are failing in Chrome 144 (and Firefox 147).

I see no evidence that this interface is supported in Chrome, although I cannot rule out that the collector has a bug, given this is interface is only available in Dedicated Workers.

@ThaBrad Can you please provide a minimal reproducible example using VideoTrackGenerator that works in Chrome?

(at least) Chromium (if not WebKit in general) based browser (94+) support it.

FWIW, Chromium is using Blink since v28.
