I have problem with creating multiple different video headers on different pages. I'm using lattest Wordpress 4.7 and using "Twenty Seventeen" template. For now i manage how to add "video header" to page different from front page, by adding in custom-header.php
video-active-callback => 'is_page'
This gave me option to set video at every page, but then i saw that i changed all headers at the same time.
So my Question is, how to create separate headers, but if it is possible with this cool feature to change video from "Customize" menu.
