I built a web site for mobile and I have a .flv file which I do not know whether it works or not.

The url I tested is
(The video is a .flv format)

(Click VIDEO 1)

I tested it in : http://iphone5simulator.com/
and it seems working fine.

The I tested it in
and it does not work.

Will you pls. indicate me what is/are the format(s) I have to convert the .flv to have that video visible in most mobile devices?
I validated all my files to W3C and I have not seen any advice about this subject.Please suggest others testers on line if possible.
