Hi,
I am currently implementing a conformance MP4 AAC decoder.. I noticed that streams produced by the MP4GUI and foobar2000 MP4 utilities has a very strange byte at the iods box type, audio profile which is set of 0x0F !!! I referred to the FhG conformance streams and the same byte is set of 0x01 !!!
I have not tried out other encoder such as NERO.. but in the case of ITune, the iods box does not exists..
Is this a possible bug??
