Hi

I downloaded the MPEG4 reference audio software from the ISO site.
http://www.iso.ch/iso/en/ittf/PubliclyAvai...rence/audio.zip

I am trying to create CELP audio elementary streams as
1. standalone CELP audio Elementary Stream form
2. CELP stream in mp4 fileformat

I am working on windowsXP.
I have been able to compile the Mp4v2enc.dsw project to obtain the Mp4v2enc.exe.

I assumed that Mp4v2enc.exe would give me the CELP stream in Mp4 file format.So i tried to encode in the following way...
[Mp4v2enc -m lpc -o .\out.mp4 .\radio_16k.wav -c "e 1 f 0 p 1" -r 14400 -b 0 -d 1]
I tried to play this out.mp4 in philips platform4 player..but it would not play.i saw the structure of out.mp4-this structure too is not in mp4 fileformat.

Can anyone please guide me..as i would like to..
(i) In which format would Mp4v2enc.exe will give me CELP stream in stream?
(ii) How do i create the CELP streams as an standalone audio Elementary stream and CELP stream in Mp4 fileformat.
(iii) I am also trying to compile the fl4_to_mp4.dsw project.but i face about 23 errors while linking.CAN ANYONE PLEASE HELP ME AS TO HOW I CAN SOLVE THESE LINK ERRORS..the link errors are as follows

[COLOR=red]CAN ANYONE PLEASE GUIDE ME AS IN SOLVING MY ABOVE ABOVE QUERIES


Thanks in Advance

If I properly understand your request, you are trying to produce MP4-compatible ACELP.net audio files. Correct?

If so, I started a related thread about Audible.com's ACELP.net implementation just over a year ago, in response to the following interaction between Menno and myself:
To date, I've received no response regarding the Audible.com query, nor any further information regarding the possibility of playing self-encoded ACELP.net streams on any portable device.
