Question

我正试图通过按下按钮在iPhone上播放来自互联网的视频流。我使用了很多代码示例但没有任何效果。使用此代码，它会打开一个黑色视图，其中没有任何视频流或控件。（流本身有效。）

NSURL *url = [NSURL URLWithString:@"http://MyStreamURL.com"];
MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayer];

moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.shouldAutoplay = YES;
[self.view addSubview:moviePlayer.view];
[moviePlayer setFullscreen:YES animated:YES];

Answer 1

而不是创建MPMoviePlayerController并将其添加到您的视图中，创建MPMoviePlayerViewController并以模态方式呈现该视图控制器可能更简单（因为您无论如何都要尝试全屏显示视频）。然后MPMoviePlayerViewController可以为您管理视频的演示。

MPMoviePlayerViewController *mpvc = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

[[NSNotificationCenter defaultCenter] addObserver:self
                                     selector:@selector(moviePlaybackDidFinish:)
                                         name:MPMoviePlayerPlaybackDidFinishNotification
                                       object:nil];    

mpvc.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;

[self presentMoviePlayerViewControllerAnimated:mpvc];
[mpvc release];

在moviePlayBackDidFinish委托方法中，您可以关闭模型视图控制器。

Answer 2

需要提及电影源类型为流媒体

moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;

Answer 3

在链接库部分

中添加AVFoundation框架工作

在.h文件中添加

#import <MediaPlayer/MediaPlayer.h>
@interface video_liveViewController : UIViewController<MPMediaPickerControllerDelegate,MPMediaPlayback>

在你的.m文件中

NSURL *movieURL = [NSURL URLWithString:@"http://172.31.17.252:1935/live/myStream/playlist.m3u8"];
movieController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
[self presentMoviePlayerViewControllerAnimated:movieController];
[movieController.moviePlayer play];
