mp4tool -extract file.mp4 4 video
extracts esid:4 from file.mp4 and puts it in files video.media (your 
.cmp), video.nhnt (the Access Units infomation) and video.info (the headers)
You can get a windows exe at
  http://www.comelec.enst.fr/~dufourd/mpeg-4/tools.html
mp4box also has something like this, in case you want to use it on 
another platform (mac, linux...). You will find the source in the GPAC 
site at http://gpac.sourceforge.net
There is also a windows exe at
  http://www.comelec.enst.fr/osmo4/gpac0.1.1/MP4Box.exe
There may be a similar function in the mpeg4ip package,
  http://mpeg4ip.sourceforge.net
