Apologies for the poor wording. How do I change the thumbnail and information displaying in the below "media bar" as sites like YouTube do?
I presume the changes needed are <meta> tags on my HTML webpage but I'm not even sure what this thing is called so I don't even know where to begin searching.
Is this something you set with specific a specific <meta> tag, or with attributes on my HTML document or HTML elements such as on the audio or video elements?
