ios - Support for background recording of video using AVCaptureSession -

i trying record video in background code recording video in foreground when app goes background method.

-(void)captureoutput:(avcapturefileoutput *)captureoutput didfinishrecordingtooutputfileaturl:(nsurl *)outputfileurl fromconnections:(nsarray *)connections error:(nserror *)error

fires error as

error:error domain=avfoundationerrordomain code=-11818 "recording stopped" userinfo=0x176aa180 {nslocalizedrecoverysuggestion=stop other actions using recording device , seek again., nsunderlyingerror=0x1766c0e0 "the operation couldn’t completed. (osstatus error -16133.)", nslocalizeddescription=recording stopped}

i set next value in demoapp-info.plist

required background modes->app plays sound or streams audio/video using airplay application not run in background->no

below code
