Are you running Linux?  Are you running X11?  then xrandr is the protocol for controlling the resolution and arrangement of each output (LCD and HDMI).  So you would typically configure the outputs side-by-side, and then the geometry of the window will position it on one side or the other.  Try running the xrandr command in a terminal, it will tell you the current configuration.

Otherwise I don’t know the details of how you control which output to use on that hardware; maybe on embedded systems there is another typical way to do it of which I’m not aware.  But I think you will need two windows, one for the application and one for the video player.
