This doesn't work.
However, specifying fps does.Code:
Just replace ## with however many Frames Per Second you want.Code:
mplayer -fps ## tv://
If you're not root, then type sudo before mplayer.
I also don't think that mplayer is designed for video chat, but, correct me if I'm wrong.;)
Don't know why anyone would want to video chat in BT, but w/e, who am I to judge?
