I have a audio streaming app that streams music from a network resource with audio files as mp4's encoded as AAC using Azure's Media Encoder. I'm using open source library's https://github.com/muhku/FreeStreamer https://github.com/douban/DOUAudioStreamer, which both use Apple's Stream Parser from the AudioToolBox framework to stream audio, but on iOS9 the framework throws a kAudioFileStreamError_InvalidFile error. Interestingly apps compiled with the iOS9 SDK continue to stream the same file perfectly on iOS7/8 devices, but not iOS9.
Now i can't figure out if Apple broke something in iOS9, or we have the files encoded wrong on our end, but they play just fine on both iOS 7/8 but not 9. Here is a sample file from our server which plays just fine on iOS 7/8 but not 9 http://patarims.streaming.mediaservices.windows.net/858959cc-a7c2-4053-9f41-9ad32b406a8b/eyhqG1mC_AAC_und_ch2_128kbps.mp4
If anyone could point me in the right direction, how do i go about debugging the issue? Do we need to re-encode our files in some specific way?
