What you're doing wrong is misunderstanding the meaning of the
'--enable' flags as they exist in MPlayer's configure. It is not the
same as the meaning of those flags in many other open-source projects
you might have seen.

By using those flags, you are disabling all autodetection of those
features; when configure sees them, it assumes that you are going to
provide all of the necessary compiler flags yourself (using the
'--extra-libs', '--with-extraincdir' and '--with-extralibdir' options).
MPlayer's '--enable' options are intended only for use by developers,
and are almost completely useless for end users.

If you remove those two '--enable' flags from your command line, you
will almost certainly see configure pick up your x264 and FAAC installs
automatically, and the compile should run without problems.

If configure does *not* pick up your installs automatically, then either
you have installed the libraries in unexpected and/or unusual locations
(and s oneed to use the '--with-extra*dir' options anyway) or
autodetection is broken. In the latter case, a bug report with a full
explanation of the relevant parts of your system configuration will most
likely get developer attention.
