       EXAMPLE MPLAYER CONFIGURATION FILE:

       # Use Matrox driver by default.
       vo=xmga
       # I love practicing handstands while watching videos.
       flip=yes
       # Decode/encode multiple files from PNG,
       # start with mf://filemask
       mf=type=png:fps=25
       # Eerie negative images are cool.
       vf=eq2=1.0:-0.8

I only searched for the word, 'flip'. If you do that you'll probably
come across the flag.
