Dynamic Video for Divi Posts dynamically embeds a video into your blog posts by using a custom field. When editing a post, a new meta box labeled “Video URL” appears. Enter a video URL (e.g., a YouTube link) into this box, and then use the [dynamic_video] shortcode in your Divi Builder template. The video is automatically embedded using WordPress’s oEmbed functionality. New in version 1.0.2: Optional setting to display the post’s featured image when no video URL is provided.

Dynamic Video for Divi Posts

Short Description: Embeds videos into posts via a custom field and [dynamic_video] shortcode for Divi, with optional featured image fallback.

This plugin lets you specify a header image for each post, page, custom post type or archive page individually, from your default headers and custom headers.
It adds a meta box in the post edit screens with the header selection and a settings field in the edit profile and each taxonomy edit screen. 
If no specific header is specified for a post it will fall back to the default selection. 
There is no change of template files necessary as this plugin hooks in the existing WordPress API to unfold its magic.
Thanks to Erik T. for the idea to this plugin!
