VLC wont play it either, and iTunes does (as of some recent version) play aac+ streams... works fine when I send the data encoded with the aacplusenc program, it just won't play it when I use the CoreAudio encoder and with my ADTS packet headers.
Unless I am incorrect that what is commonly called "aacplus" is actually AAC-HEv1 and "aacplusv2" is AAC-HEv2. If I am wrong, then what is aacplusenc actually doing? Either the CoreAudio AAC-HE coder is doing something different that aacplusenc or my ADTS header is wrong for AAC-HE packets, but correct for AAC-LC. And I'd bet on it being my error someplace.
