Hiding length of video while playing

Is there any advanced setting i can change to hide the length of a video while i’m watching it?
I watch replay of sports games and prefer not to know how long the vid is, so i won’t know if
it’s gonna be any longer, have overtime, stuff like that. I read this
advancedsettings.xml (wiki)

but couldn’t find any attribute i can use. I would like it to hide video length, and in the progress bar show as if it’s the end all the time, or something like that.
I’m capable of changing xml file etc. so I’m willing to try any advanced tricks as well,
Thanks!
