如何在iOS中使用MPMoviePlayerController播放视频流

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。我使用了许多代码示例，但都不起作用。有了这个代码，它打开了一个没有任何视频流或控件的黑色视图。（流本身工作。）

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

与其创建MPMoviePlayerController并将其添加到视图中，不如创建MPMoviePlayerViewController并以模式显示视图控制器（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];

然后，在moviePlayBackDidFinish委托方法中，可以取消模型视图控制器。

Answer 2

需要提到电影源类型作为流

moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;

Answer 3

在链接库部分中添加AVFoundation框架

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];

Answer 4

只需将"MPMovieSourceTypeStreaming"添加到"moviesourcetype"
