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.
