You're using pre-built MPlayer packages. That not a good idea IMHO.
I prefer to build my own, following this doc:

Yes, that means that your build is missing libavformat.

He's how to do it:
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 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/libavutil////

FFmpeg also contains libavformat, a library to decode container
formats that can optionally be used to extend MPlayer's container
format support. If you wish to use it, repeat the above steps for the
libavformat subdirectory of the FFmpeg source tree.
