Hello Zoom Developers, here are the updates for the **Web Video SDK version 1.3.0 release** 🙂

## New Requirement in version 1.3.0

- The `role_type` attribute in the Video SDK JWT token is required. See [SDK Authorization](https://marketplace.zoom.us/docs/sdk/video/auth) for details.

### Added

- Virtual background support, and APIs
  - APIs include: `isSupportVirtualBackground` , `previewVirtualBackground` , `updateVirtualBackgroundImage` , `stopPreviewVirtualBackground` , and `virtualBackground` option in `startVideo` method
  - See API reference for more details

- Audio and video statistic information.
  - Subscribe to audio and video data via `subscribeAudioStatisticData` and `subscribeVideoStatisticData`
  - Data will be sent every second via the `audio-statistic-data-change` and `video-statistic-data-change` events

- Support for sharing audio only while screen sharing a Chrome tab
- Support for sharing “Content from 2nd Camera” (e.g. a document camera, or the integrated camera on your laptop)
  - New `ScreenShareOption` option for the `startShareScreen` method
  - New secondaryCamera-related method: `switchSharingSecondaryCamera`
  - See [here](https://support.zoom.us/hc/en-us/articles/201362153-Sharing-your-screen-or-desktop-on-Zoom) for more details on functionality, and the API reference for usage

### Enhanced

- Datacenter selection algorithm for reduced latency and improved in-meeting performance
  - Improvements include geo-fencing and greater prioritization of geographically-close servers

- QoS for in-meeting video streams (e.g. participant videos)

### Fixed

- Occasional conflicts when starting 720p videos with virtual background
- Issue where the start audio with `speakerOnly` option on iOS mobile browser could lead to users not hearing audio
- Video rendering issue on Android mobile browsers

Thanks,  
Tommy

Hey @tommy , the data we get from `audio-statistic-data-change` and `video-statistic-data-change` events, Can we know of which user the received statistic data belongs to as currently, I don’t see any `userId` field in the payload.

I hope the problem when the participants turned on the sound when the host exited, if you specify the role\_type is fixed ? )

I described it here [V1.2.0: Improved role management: Original host - #2 by vic.yang](https://devforum.zoom.us/t/v1-2-0-improved-role-management-original-host/67768/2)

Hey @shoaib

The statistic data of audio/video is a reflection of the overall network, not the specific user. We are planning to provide the fps and resolution data for each video.

Thanks  
Vic
