Call Preview and Thumbnail

Depending on your call type settings, our system can occasionally generate a preview image (thumbnail) for your call. You can use this image to show a preview of the call in your app, typically in a lobby, waiting room, etc.

Get the preview thumbnail

import { useCallStateHooks } from "@stream-io/video-react-sdk";  const { useCallThumbnail } = useCallStateHooks(); const thumbnail = useCallThumbnail();  console.log(thumbnail.image_url);

Show the preview thumbnail

Our React Video SDK provides a built-in component to show the preview image. You can use it like this:

import { CallPreview } from "@stream-io/video-react-sdk";  export const MyComponent = () => {  return (  <div className="my-container">  <CallPreview  className="my-call-preview-class"  style={{ width: "240px", height: "135px" }}  />  </div>  ); };

Optionally, it accepts className and style props, so you can style it as you wish.
