I am trying to play video in iPhone, following is the code i have used.

Player is launched but it sonly shows loading and never play the video.
I have also imported  MediaPlayer/MediaPlayer.h
-(IBAction)play:(id)sender
{
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath = [bundle pathForResource:@"test_output" ofType:@"mov"];

NSURL *url = [NSURL URLWithString:
             moviePath];

_moviePlayer =  [[MPMoviePlayerController alloc]
                 initWithContentURL:url];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:_moviePlayer];
[_moviePlayer prepareToPlay];
_moviePlayer.controlStyle = MPMovieControlStyleDefault;
_moviePlayer.shouldAutoplay = YES;
[self.view addSubview:_moviePlayer.view];
[_moviePlayer setFullscreen:YES animated:YES];
     }

        - (void) moviePlayBackDidFinish:(NSNotification*)notification {
           MPMoviePlayerController *player = [notification object];
         [[NSNotificationCenter defaultCenter]
          removeObserver:self
          name:MPMoviePlayerPlaybackDidFinishNotification
          object:player];

if ([player
     respondsToSelector:@selector(setFullscreen:animated:)])
{
    [player.view removeFromSuperview];
}
 }

A:

First, check whether your movie file is added to your project or not.
Second, try creating path with fileURLWithPath. Replace your following code 
NSURL *url = [NSURL URLWithString:moviePath];

with
NSURL *url = [NSURL fileURLWithPath:moviePath];
