[M4IF Technotes] How can I convert a m4v to mp4 stream?

[giuseppe.spampinato st.com]

     Hi everybody,
     I have elementary bitstreams .m4v
     (compliancy with ISO standard MPEG-4)
     and I want to obtain an mp4 complete stream.
     Could someone please say to me exactly which 
     information I have to add before (and maybe
     at the end) of the mp4 stream?
     Is there an automatic program to do this?
     Thank you very much!!!
