Thanks! For anyone else struggling with autoplaying videos, I just started using the Code Embed plugin to manually enter <video> elements into post content. If you just enter the HTML into the editor it converts the meta attributes like muted to the WP syntax of muted="", which doesn’t do anything.
This lets you add whatever HTML meta properties you need. In addition to muted I’ve found that Safari in iOS stops autoplaying videos without the playsinline attribute (more info), so that might also be a good attribute to add to the WP shortcode.
Specifically, the header image isn’t loading until I enter my admin info into that pop-up, though that only makes the header appear in firefox (not IE or chrome or safari). This only just started happening, and I don’t think I changed anything recently, so any help would be greatly appreciated. Thanks!
Also my header won’t load in any thing but firefox. Any thoughts on that one? It’s a 72dpi RGB GIF.
