Coming back to this months later.
My previous hacked trivantis-media.js file does not work in Lectora 19. Oddly, Joe’s CSS does work. Except it doesn’t.
I have a file with two video files on two different pages. The CSS works on the first video but does not affect the second, at least in ReviewLink. Figure that one out. I dare you.
Note that “Controller: none” works in L19 … except that the triangle-in-circle “Play” icon is displayed on top of the video, even though it has no effect.
