Although copying is used, I've combined JavaFX and VLC in this fashion 
for over a year already, and video is smooth and stable -- stable enough 
to watch full length HD movies, at 20% increased speed (the speed I 
normally watch them).

Of course, if the target machine is barely able to play these, then the 
extra copying overhead (which is smaller than people think) may be too much.
