[BA] Constraints are applied to the track before it is input to the encoder. The encoder guidance is provided in RTCRtpEncodingParameters. This includes parameters.degradationPreference, parameters.encodings[j].resolutionScaleDownBy, maxFramerate, etc.

So I think you are asking about default values of the encoding parameters.
