@RGJ @kinetiksoft Feel free to try this component: GitHub - Arkshine/discourse-video-preloading-metdata · GitHub
It puts back the old HTML. I did not test it extensively, but it seems to work fine. 
I believe the developers have a valid reason to remove this by default as it could affect the user experience. However, providing an option would be reasonable too.(well, a theme component is an option 
).
