I found that you can turn off annotations of embedded YouTube videos by adding the &iv_load_policy=3 parameter to the url in the embed code.
Example:
<object width="425" height="344"> <param name="movie" value="http://www.youtube.com/v/PMnEvKCtHBw&hl=en&fs=1&iv_load_policy=3"></param> <param name="allowFullScreen" value="true"></param> <param name="allowscriptaccess" value="always"></param> <embed src="http://www.youtube.com/v/PMnEvKCtHBw&hl=en&fs=1&iv_load_policy=3" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed> </object>
Is there a way to force this setting on all YouTube URLs in a webpage using javascript / jQuery?
(An example like this example where you force wmode to be transparent to all flash objects)
