@Video SDK latest Web

**Description**  
We want show a preview of caller to the user who has to pick up the call. Kind of like snapchat, when you call someone, it shows your video preview to the other user before picking up the call. Can we do the same thing with zoom but before starting a call?

**Error?**  
Cannot stream a preview before joining a call.

**How To Reproduce**  
user-a initiates a call to user-b. user-b opens the preview of user-a → if it’s all good, user-b accepts the request. user-a gets notified that they are ready to join then has 20 seconds to answer. when the user-a answers they both join the call.

Hey @TheBrokenXD

Thanks for your feedback.

Do you need to preview your self video before accepting the call?

The Video SDK provides corresponding APIs for that. If you’re familiar with React, you can refer to the sample app we provide.

no I’m looking for more like - my preview to the user who has to pickup the call. I’ll be visible to them before they pickup the call. kinda like snapchat!
