RTCRtpEncodingParameters minQuality defaulted (and others)

[robin-raymond]

dictionary RTCRtpEncodingParameters {
             unsigned long       ssrc;
             payloadtype         codecPayloadType;
             RTCRtpFecParameters fec;
             RTCRtpRtxParameters rtx;
             RTCPriorityType     priority;
             unsigned long       maxBitrate;
             double              minQuality = 0;
             double              resolutionScale;
             double              framerateScale;
             unsigned long       maxFramerate;
             boolean             active = true;
             DOMString           encodingId;
             sequence<DOMString> dependencyEncodingIds;
};

I'm uncertain why minQuality is defaulted rather than left unset. I think there's need to review all the defaults and make sure they are all accurate.

To me, it does not make much sense to allow the quality of a stream to deteriorate to the lowest possible level by default. IMHO it would make more sense to drop the stream before that happens.

Since we don't know what minQuality does, why not remove it?

@aboba kill this minQuality thing; no clear guidance on what an implementer is supposed to do with it; until someone comes up with use case and guidance I don't think it should exist either.
