This example demonstrates GPU accelerating screensharing mixing with camera stream. The camera video will be resized in the foreground with the screenshare as a background texture.

Configuring a background image for the video stream is possible by setting the player poster image.

.video-js {
    background-color: #000000 !important;
    background-image: url(../../images/virtualbg.jpg) !important;
    background-repeat: 'no-repeat !important';
    background-position: 'center center !important';
}

      <video class="video-js vjs-default-skin vjs-fluid virtual" crossorigin="anonymous" controls="" id="virtual-screen"></video>
