This looks extremely over-complicated.  mencoder can directly encode
(from practically any source) to aac audio and h.264 video.  Why
do you output to raw, encode audio seperately, etc.?

You told x264 to use 3 b-frames, while lavf can't handle b-frames in
the output (hence the long lavf option) so your file is surely broken.
