if no one answered there will be a reason, right?
to crop you need to use -vf crop=...    read the man page for details;
in any case  you can't crop without re-encoding, so I suggest to store 
the original recording
as a lossless format, such as ffv1 or huffyuv (again,  man  mplayer ,  
man ffmpeg, ffmpeg -formats
to get the list of codecs)
