AVPlayer FLAC support on devices

I have an app that plays audio using AVPlayer infrastructure. I recently added support for FLAC encoded files and they play correctly on all my devices. An user with an iPod (an iPod7,1 running iOS 10.3.3) reported failure. The logs says:

Error Domain=AVFoundationErrorDomain Code=-11828 "Cannot Open" UserInfo={NSLocalizedFailureReason=This media format is not supported., NSLocalizedDescription=Cannot Open, NSURL=[...].flac, NSUnderlyingError=0x170858750 {Error Domain=NSOSStatusErrorDomain Code=-12847 "(null)"}}

Is there any reference on which encoding in supported on which devices? it's difficult to test on any combination...

Thank you in advance!

Any update to this? Did you have to build your own decoder? or was support built in?
