Category: WebRTC
Type: New or changed feature
Status: Enabled by default (Chrome 86)

Summary

This API enables the insertion of user-defined processing steps in the encoding and decoding of a WebRTC MediaStreamTrack.

Motivation

Allow applications to insert custom data processing. A specific use case we want to support is end-to-end encryption of the encoded data transferred between RTCPeerConnections via an intermediate server.
