Abstract


This document defines a set of ECMAScript APIs in WebIDL to allow media 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 developed by the Media Capture Task Force.

Status of the Document


This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index at https://www.w3.org/TR/.

The API is based on preliminary work done in the WHATWG.

While the specification is feature complete and is expected to be stable, there are also a number of known substantive issues on the specification that will be addressed during the Candidate Recommendation period based on implementation experience feedback.

It might also evolve based on feedback gathered as its associated test suite evolves. This test suite will be used to build an implementation report of the API.

Since the previous publication as Candidate Recommendation, the specification was updated with a number of bug fixes and clarifications in its algorithms. The following new APIs were added as part of these improvements: RTCRtpSender.setStreams(), RTCRtpTransceiver.currentDirection, RTCSctpTransport.maxChannels, RTCPeerConnection.onstatsended, and the RTCStatsEvent interface.

To go into Proposed Recommendation status, the group expects to demonstrate implementation of each feature in at least two deployed browsers, and at least one implementation of each optional feature. Mandatory feature with only one implementation may be marked as optional in a revised Candidate Recommendation where applicable.

The following features are marked as at risk: The value negotiate of RTCRtcpMuxPolicy The encodings attribute of RTCRtpReceiveParameters

This document was published by the Web Real-Time Communications Working Group as a Candidate Recommendation. This document is intended to become a W3C Recommendation. Comments regarding this document are welcome. Please send them to public-webrtc@w3.org (subscribe, archives). W3C publishes a Candidate Recommendation to indicate that the document is believed to be stable and to encourage implementation by the developer community. This Candidate Recommendation is expected to advance to Proposed Recommendation no earlier than 31 December 2018.

Publication as a Candidate Recommendation does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
