我首先阅读了 Scott Hanselman 撰写的一篇有关如何使用 IIS 7 平滑流式处理和转换管理器将视频流式传输到 iPhone 的文章。很棒的文章，一切都 100% 如广告所言。

我能够在 iPad 上使用浏览器并访问我公司的网站，并在浏览器中观看嵌入到 HTML 页面中的视频播放使用以下 HTML。

<html>
    <head>
        <title>iPhone page</title>
    </head>
    <body>
        <h1>Encoded stream</h1>
        <video width="640"
               height="480"
               src="http://name-of-video-here.ism/manifest(format=m3u8-aapl).m3u8"
               autoplay="true"
               controls="true" >Live</video>
     </body>
</html>

我遇到的问题是当我尝试获取完全相同的 URL“http://name-of-video-here.ism/manifest(format=m3u8-aapl).m3u8”并尝试使用“CustomMPMovie”播放它时”或“MPMoviePlayerController”来自在同一 iPad 上运行的自定义应用程序，它不起作用。

播放视频的 Objective-C

    NSURL *theURL = [NSURL URLWithString:[item url]];

    if ([[[UIDevice currentDevice] systemVersion] doubleValue] >= 3.2) 
    {
        NSLog(@"> 3.2");
        CustomMPMovie *mp = [[CustomMPMovie alloc] initWithContentURL:theURL];

        if (mp)
        {
            mp.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
            [self.navigationController presentMoviePlayerViewControllerAnimated:mp];
            [mp shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationLandscapeRight];
            [mp.moviePlayer play];
            [mp release];
        }
    }
    else if ([[[UIDevice currentDevice] systemVersion] doubleValue] < 3.2) 
    {
        NSLog(@"< 3.2");

        MPMoviePlayerController* theMovie = [[MPMoviePlayerController alloc] initWithContentURL: theURL];

        theMovie.scalingMode = MPMovieScalingModeAspectFill;

        // Register for the playback finished notification
        [[NSNotificationCenter defaultCenter]
         addObserver: self
         selector: @selector(myMovieFinishedCallback:)
         name: MPMoviePlayerPlaybackDidFinishNotification
         object: theMovie];

        // Movie playback is asynchronous, so this method returns immediately.
        [theMovie play];
    }

任何人都可以提供解释或可能的解决方案吗？

原文

I started with an article from Scott Hanselman about how to stream video to an iPhone using the IIS 7 Smooth Streaming and the Transform Manager. Fantastic article and everything works 100% as advertised.

I am able to use the browser on an iPad and go to my companies website and see a video play in the browser, embedded into an HTML page using the following HTML.

<html>
    <head>
        <title>iPhone page</title>
    </head>
    <body>
        <h1>Encoded stream</h1>
        <video width="640"
               height="480"
               src="http://name-of-video-here.ism/manifest(format=m3u8-aapl).m3u8"
               autoplay="true"
               controls="true" >Live</video>
     </body>
</html>

The problem I am having is when I try to take the exact same URL "http://name-of-video-here.ism/manifest(format=m3u8-aapl).m3u8" and try to play it using the "CustomMPMovie" or "MPMoviePlayerController" from within a custom application running on the same iPad it doesn't work.

Objective-C that plays the video

    NSURL *theURL = [NSURL URLWithString:[item url]];

    if ([[[UIDevice currentDevice] systemVersion] doubleValue] >= 3.2) 
    {
        NSLog(@"> 3.2");
        CustomMPMovie *mp = [[CustomMPMovie alloc] initWithContentURL:theURL];

        if (mp)
        {
            mp.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
            [self.navigationController presentMoviePlayerViewControllerAnimated:mp];
            [mp shouldAutorotateToInterfaceOrientation:UIInterfaceOrientationLandscapeRight];
            [mp.moviePlayer play];
            [mp release];
        }
    }
    else if ([[[UIDevice currentDevice] systemVersion] doubleValue] < 3.2) 
    {
        NSLog(@"< 3.2");

        MPMoviePlayerController* theMovie = [[MPMoviePlayerController alloc] initWithContentURL: theURL];

        theMovie.scalingMode = MPMovieScalingModeAspectFill;

        // Register for the playback finished notification
        [[NSNotificationCenter defaultCenter]
         addObserver: self
         selector: @selector(myMovieFinishedCallback:)
         name: MPMoviePlayerPlaybackDidFinishNotification
         object: theMovie];

        // Movie playback is asynchronous, so this method returns immediately.
        [theMovie play];
    }

Can anyone offer an explanation or a possible solution?
