Owl Carousel 2 with video html – set the same height all items

I want use video html in owl carousel with 1 item on screen.

I want set equal height for every item but autoHeight not working with tag video html. I found this solution but still not working if video is first slide.

My example looks like this

Owl Carousel 2 – autoHeight (multiple items)

Does anyone know how to implement this solution for video in the owl element regardless of whether the video comes first or does anyone have any solution for this?
