(Whiteboard: [p=8]) 

The default google algorithm has issues; adjustment and/or (partial) replacement makes sense.  gcp has identified some instabilities in the result ("porpoising") in certain situations.  Exactly how much improvement is needed is something that we need to investigate in real-world tests (and some dummynet/etc tests)

There needs to be a fair bit of hysteresis in the algorithm.  

You can see also my other bug on this with a simple proposed algorithm for adapting by bitrate (see https://bugzilla.mozilla.org/attachment.cgi?id=756806).

Also look to merge in encode-time measurements of load used by Chrome.

Mass change P1->P2 to align with new Mozilla triage process
Priority: P1 → P2
Moving to p3 because no activity for at least 1 year(s).
See https://github.com/mozilla/bug-handling/blob/master/policy/triage-bugzilla.md#how-do-you-triage for more information
Priority: P2 → P3

Since all the depending bugs have been closed and I believe we do have load adaptions I think we can consider this done. If it's not working as expected we should open a new bug.
