Free download of MPEG4-CELP encoder ?

Hi.

I want to know wether there are any freely available MPEG4-CELP encoders,as i want to create MPEG4-CELP streams only.
(is their any encoder that would create MPEG4-CELP streams in MP4 fileformat).

I have tried the MPEG4-CELP encoder from from mpeg4 audio reference software to create MPEG4-CELP streams in MP4 fileformat,but they dont play on any players like philips-platform4,mpegable,quicktime.


Thanks

That is because those players don't support celp at all. Changing encoder doesn't help you.

Hi

Actually i have tried playing some of the MP4 fileformat streams with Mpeg4-CELP in philips-platform4 player,and philips4-platform player does play these Mp4 fileformat stream with MPEG4-celp.
Some of the MPEG4-CELP reference streams which are in mp4 fileformat also play in the philps4-platform player.

Hence Philips-platform player and mp4player from mpeg4Ip tools does play Mpeg4-Celp streams in mp4 fileformat.

It is just that,those mp4 fileformat streams with mpeg4-celp, that i have created using the mpeg4 reference audio software are not playing in them.

i am confused if it is a player problem or Mpeg4 reference audio encoder problem.

i think we cannot say that it is a player problem as philips4 platform player and mp4player do play these MPEG4-celp streams in mp4 fileformat.


Are there any freely downloadable MPEG4-celp encoder available?

Any type of suggestions/help on the above issue is  welcomed

waiting for a positive response on the issue

Thank You

Hi,
    I ve started working on MPEG4 CELP deocder.The reference encoder doesn't put the output in a container like MP4.So it isn't decodable by any player.
                        I can't decode the ISO reference streams in the reference decoder as it doesn't ve a MP4 parser.
                                            I integrated the MP4 parser to the  reference decoder.Still I m unable to reach the correct CELP header......Can  I get a reference decoder with MP4 parser or can anyone help me with the issue.
