How to place a spinner or something while video loads?

Hi,
I would suggest to set a background image (the first frame of the video) to the BODY element with the following parameter:

body {
   background-image: url( [path/to/your/image] );
   background-position: center center;
   background-size: cover;
  background-repeat: no-repeat;
}

Bye,
Matteo

It worked beautifully! Thank you for all you do guys!

I found this article with the solution: https://www.kmbytes.com/how-to-load-a-picture-as-background-until-the-video-starts-in-mb-ytplayer/
