Hi there, I'm Matt Sergei (do call me Matt, please) and can create your javascript code quickly -
you just need VideoJS player (best open source player, the only one that supported one iPad feature in my past project) and custom scripting it.
You do know that web browser security policies for several years now disallow playing a video (unless it's muted) without user interaction e.g. he/she has to press a play button or spawns other interactive action. Mouse hover action will do.
A video poster image can be any you specify in the (video player) options.
Otherwise I'm a webmaster and developer for 26 years, scripting web multimedia more extensively in last 7+ years.
Regards and hope you're safe,
Matt
