The PictureInPictureWindow interface doesn't inherit any methods.

The PictureInPictureWindow interface doesn't inherit any events.

resize

Sent to a PictureInPictureWindow when the floating video window is resized.

Given a <button> and a <video>, clicking the button will make the video enter the picture-in-picture mode; we then attach an event to print the floating video window dimensions to the console.

const button = document.querySelector("button");
const video = document.querySelector("video");

function printPipWindowDimensions(evt) {
  const pipWindow = evt.target;
  console.log(
    `The floating window dimensions are: ${pipWindow.width}x${pipWindow.height}px`,
  );
  // will print:
  // The floating window dimensions are: 640x360px
}

button.onclick = () => {
  video.requestPictureInPicture().then((pictureInPictureWindow) => {
    pictureInPictureWindow.onresize = printPipWindowDimensions;
  });
};
