No Audio playing Video file via URL address, MPMoviePlayerController

[wannamobile]

I follow all the standard but the Video Audio sometimes got muted or just disappear at the end of the video file. Have no idea why. Does any know what might be an issue?

Could a "didReceiveMemory" warning cause this? I sometimes receive this message when it happens.

 

Thank you for you help. Please see the detail below.

 
The video file is being streamed via a URL address, format in MPEG-4 Movie, size less than 6.2 MB.

 

I have the following code:

 

- (IBAction) playMovie:(NSString*)theUrl
           setMovieType:(NSString *)theType
          setPlayOption:(int)theOption
setSenderUIButton:(UIButton *)  thisSender
{
    NSString *getvdoUrl = [[NSString alloc]  initWithString:theUrl];
    NSURL *thisVdoURL = [NSURL  URLWithString:getvdoUrl];
    [getvdoUrl release];
    getvdoUrl =  nil;
    MPMoviePlayerController *movieplayer =  [[MPMoviePlayerController alloc]
                        initWithContentURL:thisVdoURL];       
    thisVdoURL = nil;
     if (movieplayer)
    {
        self.vdoPlayer = movieplayer;
         [movieplayer release];
        [[NSNotificationCenter defaultCenter]  addObserver:self
                                                  selector:@selector(moviePlayBackDidFinish:)
                                                      name:MPMoviePlayerPlaybackDidFinishNotification
                                                    object:self.vdoPlayer];
        [self.vdoPlayer play];   
    }
                
}

-(void)  moviePlayBackDidFinish:(NSNotification*)theNotification
{

 

     MPMoviePlayerController *movieplayer= [theNotification object];    
      [[NSNotificationCenter defaultCenter] removeObserver:self
      name:MPMoviePlayerPlaybackDidFinishNotification
      object:movieplayer];   
    movieplayer.initialPlaybackTime =  0.0;   
    [movieplayer stop];           
}

 

Following are the warning messages  I received before the Video file start to play.
