Getting warning while recording " MP AVAudioSessionDelegateMediaPlayerOnly end interruption"

Question

I have been recording video successfully in my app using AVAssetWriter for long time but today I start to see some strange warning comes when I stop recording,

Scenario:

• I record the video & can record again the video multiple times [NO WARNINGS]
• I play the video in MPMoviePlayerController [NO WARNINGS]
• I record the video after playing the video and once I click stop recording I get the warning

Warning:

MP AVAudioSessionDelegateMediaPlayerOnly end interruption. Interruptor <RecorderServer> category <(null)> resumable <0>,  _state = 0

Does anyone know what might be the issue or had similar issue like I have?

Answer 1

It feels like I have solved my problem, although it was not a big issue just a minor mistake which I did,when I play video in MPMoviePlayerController , after I finish playing video using the notification, i was not releasing the player object, I thought it would be enough to unregister from the notification but it helped when i set the self.player=nil;

Seems that your audio session category is set to kAudioSessionCategory_MediaPlayback when you play which is ok. Change it to a suitable category for recording. Look the different available categories here http://developer.apple.com/library/ios/documentation/Audio/Conceptual/AudioSessionProgrammingGuide/AudioSessionCategories/AudioSessionCategories.html#//apple_ref/doc/uid/TP40007875-CH4-SW1
