-oac faac -faacopts object=2:br=128
along with some x264opts all muxed to avi

ffmpeg -i out.avi -vn -acodec copy out.aac # demux aac
mencoder out.avi -of out.h264 -of rawvideo -ovc copy -nosound #demux the h264
mp4creator -create=out.h264 -r 29.9 out.mp4 #create out.mp4 first track out.h264
mp4creator -hint=1 # hint first track
mp4creator -create=out.aac -interleave out.mp4 # add aac
mp4creator -hint=3 # hint audio track
