osx - Cannot record movie using AVCaptureMovieFileoutput -

i trying record video , i'm getting error

cannot record url <#file url> because not file url.

i define destination url follows:

nsstring *path = [[nsstring alloc] init]; path = @"/users/me/documents/my fols/recording_try/newmovie.mov"; nsurl *dest = [[nsurl alloc] initwithstring:[path stringbyaddingpercentescapesusingencoding:nsutf8stringencoding]]; 

then after creating session, input , output objects. tried recording this.

mmoviefileoutput = [[avcapturemoviefileoutput alloc] init] ; [msession addoutput:mmoviefileoutput]; [mmoviefileoutput startrecordingtooutputfileurl:dest recordingdelegate:self]; 

i have started running session, tried using begin , comitconfiguration, etc. every time run error like:

[avcapturemoviefileoutput startrecordingtooutputfileurl:recordingdelegate:] - cannot record url /users/me/documents/my%20fols/recording_try/newmovie.mov because not file url. 

i don't know i'm going wrong... please help???

thanks in advance...
