You should really read the online docs!
http://www.mplayerhq.hu/homepage/design7/dload.html has everything you
need to do a proper compilation of MPlayer from CVS. You must not copy
ffmpeg in mplayer source tree. You just need to copy libav* to mplayer
source tree:

CVS
Downloading MPlayer CVS

You can also get MPlayer via anonymous CVS. Issue the following
commands to get the latest sources:

  cvs -d:pserver:anonymous at mplayerhq.hu:/cvsroot/mplayer login
  cvs -z3 -d:pserver:anonymous at mplayerhq.hu:/cvsroot/mplayer co -P main

When asked for a password, just hit enter. A directory named main will
be created. You can later update your sources by saying

  cvs -z3 update -dPA

from within that directory.
FFmpeg libavcodec/libavutil/libavformat

CVS MPlayer is not fully functional without a copy of the libavcodec,
libavformat and libavutil libraries from FFmpeg. Get FFmpeg CVS via

  cvs -d:pserver:anonymous at mplayerhq.hu:/cvsroot/ffmpeg login
  cvs -z3 -d:pserver:anonymous at mplayerhq.hu:/cvsroot/ffmpeg co -P ffmpeg

When asked for a password, just hit enter. A directory named ffmpeg
will be created. Copy the libavcodec, libavformat and libavutil
subdirectories into the main directory just created from the MPlayer
checkout.

In order to include libavcodec and libavutil in CVS updates, add the
following lines to main/CVS/Entries:

  D/libavcodec////
  D/libavformat////
  D/libavutil////
