RTCOfferAnswerOptions

The WebRTC API's RTCOfferAnswerOptions dictionary is used to specify options that configure and control the process of creating WebRTC offers or answers. It's used as the base type for the options parameter when calling createOffer() or createAnswer() on an RTCPeerConnection.

Each of createOffer() and createAnswer() use RTCOfferAnswerOptions as the base type for their options parameter's dictionary. createOffer() uses RTCOfferOptions and createAnswer() uses RTCAnswerOptions.
