The Web Real-Time Communications Working Group has proposed amendments, including both corrections and additions, to the W3C Recommendation of WebRTC: Real-Time Communication in Browsers. This document defines a set of ECMAScript APIs in WebIDL to allow media and generic application data to be sent to and received from another browser or device implementing the appropriate set of real-time protocols. This specification is being developed in conjunction with a protocol specification developed by the IETF RTCWEB group and an API specification to get access to local media devices.

Proposed corrections and additions since the January 2021 Recommendation are listed in an appendix to the document. Comments, including implementation experience, are welcome via GitHub through 8 December 2024.
