We need to take the first track alphabetically, basically.

It's not complete I think, but it covers the constructor and some bits of
behaviour.

It should pick and lock to the right track, regardless of if it's still in the
MediaStream.

The test fix is because we don't expose tracks until the HTMLMediaElement has
loaded loading I think.

This alignes with a couple spec changes:

and also throws when no valid track are found in the MediaStream, either because
it's all video tracks or because it has no tracks.

Bugbug thinks this bug is a task, but please change it back in case of error.

For documentation purposes, this is related to the addition of MediaStreamTrackAudioSourceNode -- its main purpose is to specify what the "first" audio track is. Among other things, see this blog post: https://blog.paul.cx/post/mediastreamtrackaudiosourcenode/

Please see above comment.

James, what is the process to sort out the problem in comment 16? I've done a fix to the test. I believe it should pass in Firefox now. Chrome does not have the feature yet, it's supposed to fail there.

Flags: needinfo?(padenot) → needinfo?(james)

Sorry, I was on PTO. Where's the test fix? You should be able to push it to the GitHub PR branch and we'll reland it in m-c once we downstream the PR. Or do you mean it was fixed in some other m-c push/bug?

Note that the Chrome problem is instability, not merely the test failing (which doesn't cause the CI to fail).

Flags: needinfo?(james) → needinfo?(padenot)

It was fixed in bug 1560251. The code is correct in Gecko, how should we proceed ?

Flags: needinfo?(padenot) → needinfo?(james)

Merge the upstream PR, which will allow that PR to apply and then end up with a fixed test upstream, I think. I'll do that.

Documentation updates:

  • Added Exceptions section to the reference page for MediaStreamAudioSourceNode; listed the InvalidStateError that occurs if the stream has no audio tracks.
  • Added Usage notes section to the same page, explaining that the MediaStreamTrackAudioSourceNode node type is generally the better choice now, and why. Also includes a subsection explaining what the order of tracks is (sorted by ID using Unicode point ordering).
  • Updated Firefox 69 for developers
