我正在尝试在iOS中播放视频 - 使用URL的MPMoviePlayerController。但它不允许我加载视频。我在viewDidLoad方法中使用以下代码:
NSURL *fileURL = [NSURL URLWithString:@"http://videos.testtube.com/revision3/web/discoverydinosaurs/0035/discoverydinosaurs--0035--male-dinosaurs-battle--large.h264.mp4"];
moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[moviePlayerController.view setFrame:self.view.bounds];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.movieSourceType = MPMovieSourceTypeStreaming;
moviePlayerController.fullscreen = YES;
moviePlayerController.shouldAutoplay = YES;
[moviePlayerController prepareToPlay];
[moviePlayerController play];
它给了我以下错误日志:
<Info>: logging starts...
<Debug>: setMessageLoggingBlock: called

请帮我解决此错误。
是否真的可以在MPMoviePlayerController中使用URL播放视频???
请帮忙。
谢谢和问候。

它适用于您的网址。我试过了......
-(void)Play
{
NSURL *videoPath = [NSURL URLWithString:@"http://videos.testtube.com/revision3/web/discoverydinosaurs/0035/discoverydinosaurs--0035--male-dinosaurs-battle--large.h264.mp4"];
MPMoviePlayerViewController *mpViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:videoPath];
// Remove the movie player view controller from the "playback did finish" notification observers
[[NSNotificationCenter defaultCenter] removeObserver:mpViewController
name:MPMoviePlayerPlaybackDidFinishNotification
object:mpViewController.moviePlayer];
// Register this class as an observer instead
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:mpViewController.moviePlayer];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(doneButtonClick:)
name:MPMoviePlayerWillExitFullscreenNotification
object:nil];
// Set the modal transition style of your choice
mpViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
// Present the movie player view controller
[self presentViewController:mpViewController animated:YES completion:nil];
// Start playback
[mpViewController.moviePlayer prepareToPlay];
[mpViewController.moviePlayer play];
}
- (void)movieFinishedCallback:(NSNotification*)aNotification
{
// Obtain the reason why the movie playback finished
NSNumber *finishReason = [[aNotification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
// Dismiss the view controller ONLY when the reason is not "playback ended"
if ([finishReason intValue] != MPMovieFinishReasonPlaybackEnded)
{
MPMoviePlayerController *moviePlayer = [aNotification object];
// Remove this class from the observers
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayer];
// Dismiss the view controller
[self dismissViewControllerAnimated:YES completion:nil];
}
}
