- From the man page

md5sum
              Calculate MD5 sums of each frame and write them to a
file.  Sup?
              ports RGB24 and YV12 colorspaces.  Useful for debugging.
                 outfile=<value>
                      Specify the output filename (default: ./md5sums).

so it should work like this

mplayer IN.avi -vo md5sum:outfile=/path/to/filename
