I'm trying embed a file link. but problem is that the link is variable. for example if link is

Http://anyweb.ext/media/filename=keyXXXX.mp4

on every execution the keyXXXX changed. for example

keyXYZ, key)(%0, keyXYZX, key0987

I tried http://anyweb.ext/media/filename.mp4?keyXXXX but not working. How can I get an updated URL? If I get the updated URL, I can set it on my player using setAttribut (js). if we can run url in background and it will be updated then we can copy it and set as player source. can we do it with javascript?
