[Mp4-tech] [audiodsp] MPEG4 decoder testing

[Abhishek Ballaney]

Dear Mohan,
For testing your decoder, you need to give input files in .aac extension.  You can convert your files from .mp4 to .aac using the mp4ui utility.  It can be found at:
http://mp4ui.sourceforge.net/
For fixed point version of the codec, you can use FAAD (Free Advanced Audio Decoder).
Regards,
abhishek

Hi all
    I am working on the MPEG4 AAC decoder . I have  xxx.mp4 test vectors
but the decoder I have accepts only ADIF , ADTS  formats.
 So I am unable to do the testing, can some one let me know how do I test the decoder. 
If we need to convert the xx.mp4 files to adts of adif to test  where do I find the utility for the same. 
 Were do I get an rms calculating utility for this codec and whats the maximum tollerable 
rms value for this decoder(If any on has the rms utility for the same please send it across
if its not a problem )
 If anyone has knows the links from were I can get an fixed point version og the aac codec(open source )please let me know.
Thanks
Mohan
