You mean...?
A: I want to control videos even if the site owner has set up not to allow it.
B: I want to control videos even if the focus is not on the embedded video but on the site.
C: something else.
A: I was supposed to make this comment on "Volume Curve Designer", for some reason I did it here, but it would be taking control even if the website owner doesn't want to.
would you be able to make a script to activate the controls in embedded videos?
