Removing blocker id, not the case.

Clarifying: this impacts all the desktop platforms, but on Win + Linux it's intermittent? On Mac it is consistently failing?

Comment 3

Yes, pretty much. macOS appears to be @90% of the time.

I've just tested and I see a consistent fail on Windows. I would expect this to fail on all platforms for ESR -- when it doesn't error, does playback work?

That specific link leads to a CBCS encrypted Netflix stream (though oddly it appears to only be when given the videoParams param with those args -- otherwise it works in ESR which implies it's no CBCS). We've been landing cbcs support patches since 66 but we haven't uplifted any to ESR. This would explain why this works in release, but ESR is still unhappy. We don't anticipate CBCS streams occurring in the wild outside of test media at the moment and the new ESR (68) will have better support. Marking as WONTFIX based on that. However, I'm still interested if we're seeing intermittent fails, and what happens when we don't fail, as I would expect this to be a consistent failure path.

Yes, it did work. For me it was 1 out of ~10 attempts that the playback worked.
