Please don't top-post. We prefer inline responses on this mailing list. I mean parsing of the internals of SLSSpecificConfig() is not implemented. However, the fields you pointed out as being erroneous from AudioSpecificConfig() are indeed parsed before the main switch to parse other *SpecificConfig()s so we should be observing valid values for this. Can you please provide the sample in which you are observing these erroneous values as I asked in the first response? > What are you actually trying to achieve?" > > What I am interested in is to read the SLS specific data (e.g > core_present, pcm_wordlength etc) from the file so that I can provide > those information to my decoder which can then decode SLS-AAC codec. I see. From what I have read, this is certainly possible in theory but we need a sample to debug. Have you implemented your own SLS-AAC decoder?
