First, the existing configuration parameter (use_datagram_transport) is now optional. The new field trial has two flag values: 1. Whether to enable the datagram transport (enabled) 2. Whether to use the datagram transport by default (default_value) The first is a kill-switch. It disables the datagram transport, even for applications which inject a datagram transport factory and specify use_datagram_transport = true. This allows applications which hard-code a datagram transport to switch it off via field trials. This flag defaults to true, to avoid breaking downstream projects which already inject and configure a datagram transport. It may be changed to false after updating downstream to set this field trial flag to true when required. The second provides a default value to be used in case the aforementioned use_datagram_transport parameter is unset. Applications which explicitly set use_datagram_transport will use that value. Applications which do not explicitly specify whether or not to use the datagram transport will use it (or not) according to the default_value flag. One goal of this flag is to simplify rollout in applications which already set field trials based on configuration, but require code changes for new RTCConfiguration parameters. A second goal is to provide platforms with a knob to control whether datagram transport is "opt-in" or "opt-out". This flag defaults to false, to prevent downstream projects from unintentionally enabling the datagram tranpsort.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
