x264 "presets" are strictly part of the "x264" program itself, and not in
the library at all. You can find the presets in x264.c, where all the
options are parsed. Look for "OPT_PRESET". The options should all directly
translate to mencoder options for the -x264encopts parameter. However,
depending on the version of mencoder and x264, some options may not be
supported.
