问题
I have been working with the demo provided at http://code.google.com/apis/ajax/playground/?exp=youtube#chromeless_player. What I am wondering is if there is a way to make the player HTML5 or compatible with ios devices. I can't seem to figure out how I would do that? I don't think the code works out of the box as I have tried it from my iphone and it doesn't seem to work... The biggest reason I am using this is because I need to be able to adjust volume and get the video event changes...

As of today (2-28-2012) there is no way to play video in-line within a browser on iOS devices. You can only proide links that will either play the video in the iOS video player, or in the youtube app. The Youtube HTML5 player does this. On HTML5 enabled devices that do not support flash, it will serve an HTML5 tag.
March 7 is some big announcement for iOS, so maybe this will change then. But I do not expect it will as this is a long-standing way of operating on iOS devices.
EDIT - Here's how to do it.
To make this work for iOS, use the new HTML5 youtube player. Instructions and code found here in the YouTube API Blog: http://apiblog.youtube.com/2010/07/new-way-to-embed-youtube-videos.html
