[MPlayer-users] Slave mode bugs (?) and Java Swing embedding

[Alex Sherwin]

I do this in a  Java now.  You can use Swing or SWT (SWT is actually
easier, they expose the window handle  on frames, in Swing you have to
use a hack that is not "supported" in the JDK, but exists and works
from 1.4.2 to the latest 1.6)

Unfortunately, if you read the man page for the -wid option, you will
see that it only works on Windows.  I've spent awhile trying to find a
way to make a x-platform java Swing or SWT app that will embed MPlayer
on Windows Linux and OS X through Java Web Start.  The closest I've
been able to come is to deliver an app that embeds MPlayer on Windows,
and provides a slimmed down interface on Linux and OS X to control
mplayer, which will open its own video display window.

I spent a bit of time on this mailing list and the IRC channel trying
to figure out a way, and had someone point me to the code where the
MPlayer GUI manages to embed the player, but this is able to do it
using shared memory segments to paint the display (which you would not
be able to accomplish with Java)

Good luck on Linux, but I'm going to say its not possible...
