What’s New and How You Can Use It
The Vonage Video API team recently released a new version of the Vonage Video Client SDK - v2.20 (formerly TokBox OpenTok). Below, you will find details about the new features and examples of how they might be used.
Screenshare Improvement: Content Hints
contentHint (available for Web and coming soon to Native SDKs) provides an additional level of improvement to video and screen sharing quality by helping the encoder prioritize either high frame rate for motion-rich content or high image quality to emphasize details. Content hints also help stabilize screen sharing bandwidth utilization and bandwidth estimation.
You can direct the browser to use one of the following encoding methods to better tailor rendering for the type of content:
- Motion — Best used when capturing motion is important, such as cars passing by or sports. Smooth motion will be prioritized over image clarity.
- Detail — Best used when trying to capture video details. A crisp picture will be prioritized over video smoothness.
- Text — Use only for text or where pixel-perfect recreations are necessary. This creates full-resolution frames for all simulcast layers but may significantly impact framerate in poor networks.
- " " — no hint is provided
To learn more about how to take advantage of content hints in your application, see the setVideoContentHint Developer Reference.
Force Mute Participants (Beta)
For everyone who’s been wanting to give their meeting hosts the power to mute any participant at will - wait no more!
- forceMuteAll - mute all publishers currently in a session.
- forceMuteStream - mute a specific stream in the session

Vonage Video API Support for Plan B and Unified Plan Session Discovery Protocols
Google is now in the final stages of Unified Plan transition — which brings Chrome browser in line with the webRTC draft spec for browser interop. Previously, Chrome browsers relied on Plan B as a temporary bridge to full browser interop.
Since rolling out the much-awaited Unified Plan earlier this year, Google has announced that they will remove support for Plan-B from Chrome in August 2021.
In response to this change, our platform has been transitioning Vonage Video clients in browsers to strictly use Unified Plan. This transition is happening via a patch release to versions 2.18, 2.19, and 2.20 of the web SDK.
Getting Started With the New Features
The 2.20.0 is already available to Vonage Video API customers running on the Standard Environment, and we plan on releasing it to the Enterprise Environment in the coming weeks.
