Dear All

  I have the issue on the m4a (Mpeg 4 Audio), The basic thing what
  I have to do is that I have to read the m4a audio and play back,

  The First basic thing I did is that, I copied all the data into the
  new file i.e abcd.m4a as the copy_abcd.m4a and then playing the
  file into the foobar player, I observaed that the copied file
  i.e copy_abcd.m4a is playing fine,

  Now what I have to do is I have to play the file by skipping
  some amount of the data, (Forward Skipping)

  so i skipped some amount of data (Here I skipped in terms of bytes),
  and then made the file again names as the skipped_abcd.m4a, Now when
  I play this file into the foobar then i see that it says about the
  error, that it cannot play,

  Again searched for the soulution of this, I came to know that
  and read the site, and worked accoreding to it,
  http://www.dv.co.yu/mpgscript/mpeghdr.htm

  but not getting the proper solution to solve my problem.

  please let me know what I am missing and which is the concern API
  in ISO/SC29 Refrence Software Guide,

  I am new to the MP4, as most of my previous work is realted to the
  ITU G7XX series.

  Thanks In Advance
  Reagrds
  Ranjeet
