i want to ask here of how to find the url of the video embedded from a site.. my question was not so specific so i'll try to give an example..
for example at youtube.com the video file that they upload from their server has an extension of .flv but upon looking at the source code of their site(or a certain page on their site) you cannot find an flv file there.. so is it still linked to another file? how will i look for it?
by the way my question was not specifically intended just for youtube's source code i want to know of how was it done even on other video sharing sites....
i know every site has their own coding but i'll wait for as many answers as i can have here... thanks...
