I am working in IPOD App. Below points are main functionalities in this app - Audio recording or play (Using AVAudioRecorder for recording and AVAudioPlayer for play) - Always idle mode ON or guided access is ON/OFF - Play video using MPMoviePlayerController(not Streaming Video) - Pitch detection uses below link and it is active throw out the application and detects the sound frequency per second https://github.com/irtemed88/PitchDetector My difficulties/Questions is ...
if device is in a idle mode and guided access is ON without any user interaction for 48 hours then below issues occurred in IPOD - The movie player in the app plays the video but without sound or distortion in it. - while playing the recorded message which has same sound distortion.
I did refer the below StachOverFlow link which is similar to my difficulties but there is no update on it. https://stackoverflow.com/questions/4734295/avaudiorecorder-memory-leak
This might happen if there is any memory leak generated in the specified duration. You can create a background task for every 24 hours ( assuming your video and audio plays properly for 24 hours) and then reallocate your recorder and player objects and then test the app.
