You might want to try xvid, this codec is faster and has slightly higher 
quality than libavcodec. Quality should be very close to x264.

Example:
for PASS in 1 2
do
    mencoder bla.avi -oac mp3lame -lameopts abr:br=96 -ovc xvid \
    -xvidencopts  \
 vhq=3:bvhq=1:chroma_opt:quant_type=mpeg:bitrate=1000:turbo:pass=${PASS} \
    -o xvid.avi
done
