How to disable full screen?

There’s no current option to disable fullscreen, but if you’re using the Video.js player you could try adding this to your custom CSS:

.vjs-fullscreen-control.vjs-control {
    visibility: hidden;
}

This method works with Video.js, thank you!

I noticed that if there are a few videos on one page, they can play at same time with Video.js enabled. Is there a way to force only one video at a time like in WordPress Default player?

If you want to use the WordPress default player, use this CSS to hide the fullscreen button.

.mejs-button.mejs-fullscreen-button {
    visibility: hidden;
}

I didn’t know that the WordPress default player stopped playback of other videos. Video.js doesn’t have this feature built in. You’d have to write some JavaScript. I might work on that for a future version of the plugin.

Works perfectly fine with WordPress Default player, thank you!!!!
