Opus DTX audio (beta). This update adds platform support for Opus DTX (Discontinuous Transmission) for audio streaming. This optimization is intended to reduce the bandwidth of audio streams, which could be used for large sessions with many audio participants. This beta is enabled with client SDK updates. This was previously supported in OpenTok.js only (version 2.21.1). With this update, all client SDKs support Opus DTX.

October 22, 2021 — Platform updates (standard environment)

Selective stream API for archives and live-streaming broadcasts. Added new stream selection API that you can use to manually select which streams are added and removed for the composition of archives and live-streaming broadcasts. See Selecting streams to be included in an archive and Selecting streams to include in live streaming broadcasts.

Timestamps on HLS broadcasts. Added a new timestamp 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.

Sender-side rate control (Publisher). This update includes support for sender-side rate control (publishers only). This update is intended to improve the bandwidth estimation/bitrate control algorithm for better video quality and quicker ramp-up of published streams.

Opus DTX audio (beta). This update adds platform support for Opus DTX (Discontinuous Transmission) for audio streaming. This optimization is intended to reduce the bandwidth of audio streams, which could be used for large sessions with many audio participants. This beta is enabled with client SDK updates.

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.

April 27, 2021 — Platform Update (Standard and Enterprise environments)

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.

The Best Fit layout type will automatically increase to 4x4 grid layout for both composed archives and live streaming broadcasts to support up to 16 video streams.

Higher bitrate audio archives files and broadcasts The platform update includes support for 128kbps audio in MP4 archive files. This will increase bitrate of archives, allowing higher fidelity audio within recordings and broadcasts to benefit certain application use cases. See the Archiving developer guide.

AV Synchronization optimizations for composed archives and live streaming broadcasts This video platform update includes a number of optimizations to handle poor network conditions during real-time composing to improve resilience of audio/video synchronization in composed archives and live streaming broadcasts.

February 26, 2021 — Platform Update (Standard Environment)

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.
