most of you might already know you can hack youtube and watch high quality videos in its site by simply adding "
&fmt=18" at the end of the video..
example:
"http:/ww.youtube.com/wtch?vHWVk-uzU" <- original URL..
"http:/ww.youtube.com/wtch?vHWVk-uzU
&fmt=18" <- hackd!
............................
but!to embed high quality youtube videos in websites/blogs/forums, u'll need a different approach....instead of "&fmt=18", u need to insert "
&ap=%2526fmt%3D18" to the end of video clip’s URL specified in “param value” and “embed src”. For example:
(original code:)<object width=”425″ height=”344″><param name=”movie” value=”http://www.youtube.com/v/_w0AwGCjqnw&hl=en&rel=0″></param><embed src=”http://www.youtube.com/v/_w0AwGCjqnw&hl=en&rel=0″ type=”application/x-shockwave-flash” width=”425″ height=”344″></embed></object>Apend the
&ap=%2526fmt%3D18 to the end of two instances of
http://www.youtube.com/v/xxxxxxxxxxx&hl=en&rel=0 within the original quotation mark, where xxxxxxxxxxx represents the unique video ID.
The high quality YouTube embed looks like below:
(hackd!
<object width=”425″ height=”344″><param name=”movie” value=”http://www.youtube.com/v/_w0AwGCjqnw&hl=en&rel=0&ap=%2526fmt%3D18″></param><embed src=”http://www.youtube.com/v/_w0AwGCjqnw&hl=en&rel=0&ap=%2526fmt%3D18″ type=”application/x-shockwave-flash” width=”425″ height=”344″></embed></object>......... try it.. if it doesnt work u can sue me..
