@fippo That is a very impressive list of bugs!

@orphis @alvestrand Are we looking to modify the negotiation process (e.g. filter codecs emitted by `createOffer()`)?   Or we talking about a parameter setting?  

In a scenario where the preferred codec is only supported in hardware, `setParameters("prefer-software")` would imply attempting to modify the envelope of what is negotiated in Offer/Answer, which is not permitted in WebRTC 1.0.  So the parameters approach seems problematic to me. 

Instead, could we have an extension to `setCodecPreferences()` which affects how `createOffer()` and `createAnswer()` behave.  If that's the case, then the change will only take effect when negotiation completes.
