Shaka player bustage doesn't sound good. We've got our final 65 Beta build tomorrow before next week's RC. Nils, can you help make sure we get an owner assigned ASAP?

Flags: needinfo?(drno)

I'll start to take a look today, sorry for the delay.

Assignee: nobody → alwu
'NS_ERROR_DOM_MEDIA_WAITING_FOR_DATA' and 'NS_ERROR_DOM_MEDIA_CANCELED' are not the decoding error, so we should
also treat them specially like what we did for 'NS_ERROR_DOM_MEDIA_END_OF_STREAM'.

NI jya for the question pending in Phabricator. This feels like a regression we don't want to ship in Fx65, but we're building the RC on Monday... :\

Bug 1519317 - handle non decoding errors when we seek back to the start position.

[Beta/Release Uplift Approval Request]

Feature/Bug causing the regression: Bug 1498440

User impact if declined: Shaka player won't be able to replay

Is this code covered by automated tests?: No

Has the fix been verified in Nightly?: No

Needs manual test from QE?: Yes

If yes, steps to reproduce: Reproduce steps is mentioned in comment0.

List of other uplifts needed: None

Risk to taking this patch: Low

Why is the change risky/not risky? (and alternatives if risky): It doesn't introduce any new feature and logic, what we do here is not to return error and handle it properly so that the video can be replay again.

String changes made/needed: no
