Hi,

I have the ISO reference software of the HE-AAC v2. Its currently decoding only SBR but not the PS if I use the stream with SBR and PS.
Is there any macro to be enabled for PS decoding to work ?
Its currently generating half the data.

Thanks,

PS, and if that doesn't work, try looking at the help screen of the decoder.

The PS decoding related function ( DecParFrame() ) is in decifi.c file and are put under a Switch statement which selects according to the object type "aot". We are always getting the "aot" as AAC_LC while initialization of parametric decoding i.e. DecParInit() funciton is under the "aot" type ER_PARA.

However we are getting full output(double that of one with ISO reference code) with 3gpp fixed point implementations.

Thanks,




I forgot to tell you that using PS in preprocessor definition doesn't do.

Thanks,
I got it from your personal message and now its running fine with the mp4mcDec folder.

Hi,
Can u plz tell me from where u had taken Reference code of HE-AAC and its reference bitstreams.

We took it from the ISO website.
for the reference software for eAAC+, use the one with "mc" folder.

sorry i cant answer, i just starting to build a decoder as well.

could you tell me from where did you got the standard software? could one use it for his own needs?
