Inline youtube video doesn't work in cordova application on iOS

I develop a mobile application with cordova, and I really need to be able to play inline youtube video.

I tried to resolve it for a while:

• I set the attribute playsinline to 1 in the youtube iframe API

• I put <preference name="AllowInlineMediaPlayback" value="true"/> in my config.xml

• Then I set AllowsInlineMediaPlayback to true in the plist in Xcode

• I even try to put webkit-playsinline directly on the iframe

The results are weird. When I play my video the first time, it goes fullscreen. So I inspect my HTML via the remote developer tools to check if the attribute is well set. It is! I do as I would edit it, I leave it without modification, and the magic happen: my video plays inline!

Obviously, I can't ask my users to do this trick.

Someone have an idea to solve this out?

It's kind of an emergency issue...
