Upgraded WebRTC media engine for Video iOS & Android SDKs

Today we are releasing two major version increments of our mobile SDKs for Video, iOS 4.0 and Android 6.0. The Chromium WebRTC engine in these SDKs has been upgraded from m67 to m83. In addition to the security and performance improvements, this WebRTC engine supports Simulcast screensharing and private IP concealment via mDNS.

These iOS and Android SDKs have added support for remote participant reconnecting events. Opus DTX is now included and enabled by default. In addition, the Android capturing and rendering programming models have been updated to provide developers with more flexibility and control. The iOS SDK is now built with Xcode 12.0 and delivered as .xcframework, and the application screen sharing capability has been simplified.

With the WebRTC upgrade developers get the latest enhancements to WebRTC and ensure compatibility with recent browser releases. Opus DTX significantly reduces the bandwidth consumed by silent participants. Remote reconnecting events provide developers a way to provide visual cues to users when automatic reconnections are happening.

For a full description of all the changes, see the Android SDK 6.0 changelog and the iOS SDK 4.0 changelog. The migration guides for moving to these new SDK versions are documented here and here.
