I got a video element on a page that's working fine both in safari mobile and desktop. I have a seme-transparent pull-down menu that's working fine. The problem is, when the menu is over the video element, on the desktop safari i can see the video under the menu (as desired), while on the mobile version the video element stay on the foreground (ugly) no matter what i tell the css. Is there any workaround?
Unfortunately not.
Based on my experience and understanding of how iOS currently works, this isn't possible.
Mobile Safari on the iPad cuts a hole for a Quicktime window , which plays back the video using the built in hardware acceleration to improve battery life. (The iPhone and iPod Touch just open it up in a separate window to achieve the same effect.)
This window doesn't play nicely with the other HTML on the page. In fact, I haven't found a way to get mobile Safari to display anything on top of a tag. My guess is that this is because the hardware acceleration only allows for video scaling and positioning, and that it's only able to handle one video at a time.
I have managed to place a menu div over a html5 video tag in mobile-safari on the ipad. To be honest I didn't have any problems and it just worked. It could be though because I was using CSS3 animations and therefore the GPU? You could try using a hack to add an element to the GPU. If you put -webkit-transform: translateZ(0); on the element it should force it to use the GPU...
