문제
I am using the following code to play the video. Actually it is playing very nicely. Sometimes i get the following error -[AVFileValidator fpItemNotificationInfo:]: unrecognized selector sent to instance 0x8114e50 . When i searched about this i reached to private section of media player. I didn't understand really what it means. Please help if any one knows the answer.
-(void)playerPrepare
{
player.view.frame = CGRectMake(0.0f, 0.0f, 480.0f, 320.0f);
[self.view addSubview:player.view];
[player setControlStyle:MPMovieControlStyleNone];
[player play];
}
-(void)breadInPlate
{
// Do any additional setup after loading the view from its nib.
NSString *url = [[NSBundle mainBundle] pathForResource:@"10_Anim_iPhone"
ofType:@"mp4"];
NSURL *movieURL = [NSURL fileURLWithPath:url];
player = [[MPMoviePlayerController alloc]
initWithContentURL:movieURL];
[[NSNotificationCenter defaultCenter]
addObserver:self
selector:@selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player prepareToPlay];
[self performSelector:@selector(playerPrepare) withObject:nil afterDelay:0.5];
breadTimer = nil;
}
-(void)viewDidLoad
{
breadTimer = [NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(breadInPlate) userInfo:nil repeats:NO];
}
- (void) movieFinishedCallback:(NSNotification*) aNotification {
player = [aNotification object];
[[NSNotificationCenter defaultCenter]
removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:player];
[player.view removeFromSuperview];
[player release];
player = nil;
}
While running the code occassionally i am getting the folllowing error.
