Simple "Play" as film effect

[VirtualGit]

Like Google Photo (and probably others), you may prefer a "Play" button overlay on videos rather than the "film" effect.

I paste here a quick modification of add_movie_frame function that generate such play button instead of the film effect. It's not perfect as two "play" buttons appears overlayed when used with Bootsrap theme and "Photoswipe slideshow" (I didn't test other configurations).

I'm sorry, I have no time to make a PR and improve integration (choice of effect, ...), I just give you the code as is in the hope you will consider it, or maybe it will be usefull for someone.

The result looks like this :
