  You don't have to go too deep.  If you create a Composite with the
style bit SWT.EMBEDDED, it will create a GtkSocket.  This will set the
variable composite.embeddedHandle on that composite to be the window ID
which you can pass to clients which support XEMBED.

  IIRC, ffplay uses SDL to display video.  If so, you could probably
fork off an ffplay process after setting the SDL_WINDOWID environment
variable to be the embeddedHandle of the composite.  I think this might
"just work".
