Youtube HTML5 Video Player Fallback with Player API (v2)

问题

I'm trying to use the youtube javascript player api to embed youtube videos into my site and control them via clickable thumbnails / javascript. I thought that the youtube player would fall back to html5 videos, but it doesn't. Is there a way to set this up? Here's the code (just using swfobject to embed the video per youtube's instructions):

var vidString = "http://www.youtube.com/v/" + vidID + "?enablejsapi=1&playerapiid=video_player&version=3";
        swfobject.embedSWF(vidString,"video_player", "768", "432", "8", null, null, params, atts);

Ah - this was a bit hidden away, but I was using the wrong API. Apparently the HTML5 fallback feature only works with the iframe API, documented here:

Switched to this and it worked pretty well.
