[MPlayer-users] Precise seeking / video cutting

[Saurabh Singhvi]

Hi,

IIRC, there is an option (you'll have to do man mplayer) which
allows for exact frame usage. I think if you search for exact in
the man page, you should probably find it.

sorry that I don't remember the exact option.

cheers
Saurabh
