Microsoft WMA9 also has ACELP.net

It is free if you are using Windows OS wink.gif

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
sabeel

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.
