I know MP3 is not open source format but proprietary and I found this website http://mp3licensing.com/help/developers.html that states that you need a license for basically everything that uses MP3. But the thing is that even hardware devices that support MP3s need license. So if a mobile phone is able to play MP3s already do I need an extra license for my application that would be launched, let's say, on Appstore on Google Play Store?
If I develop a media player for mobile or desktop do I have to pay for a license if my player is able to read MP3 files?
