在iOS7上播放视频流 [英] Playing a video stream on iOS7

问题描述

我正在尝试在iOS上播放简单的直播链接。有一个视图控制器带有一个按钮，其播放动作定义如下。

I'm trying to play a simple live stream link on iOS. There's one view controller with a button with a play action defined as below.

- (IBAction)play:(id)sender {

    NSString *path = @"http://asish.flashmediacast.com:2135/live/International/playlist.m3u8";

    MPMoviePlayerController *mp = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:path]];
    [mp.view setFrame:[self.view bounds]];
    [mp prepareToPlay];
    [mp play];
}

当按下按钮时没有任何反应。我检查了链接，它工作正常。我哪里错了？

Well nothing happens when the button's pressed. I've checked the link, it works fine. Where'm I going wrong?

我找到了一个解决方案，告诉你创建一个MPMovieViewCOntroller

I found a solution that tells you to create a MPMovieViewCOntroller

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];

问题是如何调用此ViewCOntroller？

Question is how do I call this ViewCOntroller?

推荐答案

看看这个链接。问题不在于URL，它完美地与 MPMoviePlayerViewController 一起玩。

Look at this Link. The Problem is not with URL, its perfectly playing with MPMoviePlayerViewController.

-(IBAction)btnVideoClicked:(id)sender
{
    @try 
    {
        NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];
        GetVideos *obj_video = [arrVideos objectAtIndex:[sender tag]];
        MPMoviePlayerViewController *moviePlayerViewController = [[MPMoviePlayerViewController alloc]initWithContentURL:[NSURL URLWithString:obj_video.VideoPath]];
        [moviePlayerViewController.moviePlayer setControlStyle:MPMovieControlStyleFullscreen];
        [moviePlayerViewController.moviePlayer setShouldAutoplay:YES];
        [moviePlayerViewController.moviePlayer setFullscreen:NO animated:YES];
        [moviePlayerViewController setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
        [moviePlayerViewController.moviePlayer setScalingMode:MPMovieScalingModeNone];
        [moviePlayerViewController.moviePlayer setUseApplicationAudioSession:NO];
        // Register to receive a notification when the movie has finished playing.  
        [[NSNotificationCenter defaultCenter] addObserver:self    selector:@selector(moviePlaybackStateDidChange:)      name:MPMoviePlayerPlaybackStateDidChangeNotification    object:moviePlayerViewController];
        // Register to receive a notification when the movie has finished playing.  
        [[NSNotificationCenter defaultCenter] addObserver:self     selector:@selector(moviePlayBackDidFinish:)    name:MPMoviePlayerPlaybackDidFinishNotification     object:moviePlayerViewController];
        [self presentMoviePlayerViewControllerAnimated:moviePlayerViewController];
        moviePlayerViewController.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
        [moviePlayerViewController release];
        [pool release];
    }
    @catch (NSException *exception) {
        // throws exception
    }
}
