Splitting this out of bug 1157797 for further granularity.
If we've got our state graph set up properly, the watch target should be notified automatically whenever anything relevant changes.

I am worried this will regress bug 1093399. Can you have a test?

Works fine it seems - I'm not sure why we'd need this, given that the MDSM will automatically trigger UpdateReadyState when mNextFrameStatus gets to a good state. I'll push when inbound reopens.

That's why we used to update readyState again when getting some bytes downloaded to re-compute CanPlayThrough() again.

Hm that's a good point - I've backed out that one part. https://hg.mozilla.org/integration/mozilla-inbound/rev/ccd154afb3c1
