As an open question, does the issue with the Web Client SDK and `SharedArrayBuffer` have any impact on the Web Video SDK if we are running versions 1.0.3 or 1.1.0? My assumption is that it does not, but wanted to explicitly confirm.

Hey @brianWD

Thanks for your feedback.

Web Video SDK also needs to follow the Web Isolation. The following is the guide:

- Apply `SharedArrayBuffers` [origintrials](https://developer.chrome.com/origintrials/#/trials/active) for your domain. This temporary extension works until the Chrome 94 release.
- Or [Enable cross-origin isolation](https://web.dev/cross-origin-isolation-guide/) for the Web SDK.

Thanks  
Vic

@vic.yang do we need to add headers to nginx for the web video sdk, or is it adequate to have registered our domain in origintrials? How do I know if we’ve done this adequately for Zoom?

@victor.aprea You can choose one, and I suggest you can apply the origin trials first, because the Chrome team may change the policy.

@vic.yang OK, I did that. How can I verify if it had the desired effect?

Hey @victor.aprea

Try `typeof SharedArrayBuffer ==='function'` on your console. If the value is `true`, it’s correct.

Thanks  
Vic
