Cannot overlay div if background color is transparent

I am having an interesting problem. I want to have a box with a border overlaid on top of a vlc web player. I can get it to work just fine if the background color is not transparent, but as soon as I set it to transparent, it gets drawn behind the player. Does 开发者_C百科anyone know how to get around this?

Here is a jsfiddle that shows what I am talking about (You need to have vlc web plugin installed in order for this to work. Additionally, you can only do overlays with firefox, for some reason).

This post is old, but if someone with the same problem find it (like me), here is the solution :

VLC plugin have the attribute "windowless" you can use in this situation. Just add windowless="true" in the embed tag.

From the documentation :

windowless: (since VLC version 2.0.6) Draw the video on a window-less (non-accelerated) surface and allow styling (CSS overlay, 3D transformations, and much more). Default: false
