If I use the audio decoding libraries included in iPhoneOS (ex. AVAudioPlayer). Do I still have to pay for a license from Thomson, or VIA Licensing to legally decode AAC or MP3 files in my app?
Edit:
I was unable to find an exact answer from ADC(they did not know), and I am also curious about audio library’s on other platforms (Windows, Mac, Android…) So I am adding a bounty to this question.
I’m afraid the only definitive answer would come from a court of law. The patent-holders will cheerfully answer “yes” to almost any question that begins with “should I be paying royalties,” and asking anyone else is more or less a request for legal advice.
I also suspect very strongly that Apple has not obtained a blanket AAC/MP3 patent license on behalf of all iOS developers – I think we’d have heard about that.
