field on HLS broadcasts, which can be used
to synchronize HLS data and know the delay while delivering HLS broadcasts. This can be used
to coordinate events, such as chats and emojis, among endpoints playing HLS broadcasts.
See the Live streaming broadcast developer guide.

This is a beta feature. Set the video
property to true
when you call the REST API method for
initiating a SIP call.
REST API method for sending DTMF tones to SIP clients You can use a REST API method to send DTMF digits to SIP clients connected to a Video API session. See Sending DTMF digits to SIP clients.

Updates to Video API client SDKs for Web, iOS, and Android (version 2.20.0) See the release notes:
Portrait orientation for composed archives and live streaming broadcasts This feature updates the video platform to support vertical compositions that are suitable for mobile devices in portrait orientation. New layout resolutions include portrait SD (480x640) and portrait HD (720x1280). Predefined layouts (such as Best Fit, Horizontal Presentation, and Vertical Presentation) have been optimized for presentation in portrait orientations. See the documentation on customizing the video layout for composed archives and live streaming broadcasts.
The following features are now available in the Standard and Enterprise environments:
More simultaneous video streams (up to 16) in composed archives and live streaming broadcasts This platform update increases the maximum number of supported video streams in composed archives and live streaming broadcasts from 9 to 16 video streams.

Longer Archive Recordings The Vonage Video Archiving API has been updated to 240 minutes, so users can archive longer meetings and video sessions (see archive duration). Automatically archived sessions will restart recording at 4-hour intervals.
New Screen share layouts for composed archives and live streaming broadcasts New screen-sharing layouts prioritize screen-sharing streams so that the user’s presentation or share always takes precedence in the archive or broadcast (see Layout types for screen sharing). Use this feature, along with the layout stream prioritization rules for composed archives and broadcasts, to make sure presentations, screen shares, and selected streams get priority in archives and broadcasts.
Increased number of audio participants composed archives and live streaming broadcasts Composed archives and live streaming broadcasts now include audio from up to 50 participants simultaneously (up from 9 streams previously). See the archiving and broadcast developer guides.
Screen share optimizations This platform update includes optimizations to prevent subscribers on poor networks from bringing down the quality of non-simulcast video streams, like screen-sharing streams, for other participants.
