Answer 1

// Choose video from library     
         UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; 
         imagePicker.delegate = self; 
         imagePicker.mediaTypes = 
         [UIImagePickerController availableMediaTypesForSourceType: 
         imagePicker.sourceType]; 
         imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
         [self presentModalViewController:imagePicker animated:YES]; 
         [imagePicker release]; 

// Video Get

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
    [picker dismissModalViewControllerAnimated:YES]; 

    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; 
    if ([mediaType isEqualToString:@"public.image"]){ 
     NSLog(@"found an image"); 
    } 
    else if ([mediaType isEqualToString:@"public.movie"]){ 
     NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL]; 
     NSLog(@"found a video"); 
     NSData *webData = [NSData dataWithContentsOfURL:videoURL]; 
     } 

} 

// Video abspielen

MPMoviePlayerViewController *movie = [[MPMoviePlayerViewController alloc] initWithContentURL:url]; 
[self.view addSubview:movie.view]; 
[self presentMoviePlayerViewControllerAnimated:movie]; 
[movie release];
