我的应用在文档文件夹 /playlists/ 中有视频内容 - 它是我使用 m3u 格式的播放列表文件夹。/videoContent/ - 这是视频文件夹。

第一的。当我使用代码运行播放器以从服务器加载播放列表和内容时

player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:@"http://mbp.local/rat/playlists/Playlist.a60df6084e7d38b12f84afc602bb39ef.m3u"]];

m3u

#EXTM3U

#EXTINF:3000,abc
http://mbp.local/rat/videoContent/1.82aa02198c0255eddc1e538c184c176b.mov

#EXTINF:3111,cab
http://mbp.local/rat/videoContent/9.4e574f9485a9031c536425b7f79ef545.mp4

这不适用于日志中的消息：

2014-01-11 04:06:04.573 RAT[736:70b] Internal Log: Video playing
2014-01-11 04:06:04.606 RAT[736:70b] Internal Log: Video paused

    new = 2;
    old = 0;
}

第二

当我尝试从文档文件夹播放播放列表时。

player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:[NSString stringWithFormat: @"%@/playlists/Playlist.a60df6084e7d38b12f84afc602bb39ef.m3u",documentsFolderPath]]];

m3u 具有规范中描述的相对路径。

#EXTM3U

#EXTINF:3000,abc
../videoContent/1.82aa02198c0255eddc1e538c184c176b.mov

#EXTINF:3111,cab
../videoContent/9.4e574f9485a9031c536425b7f79ef545.mp4

然后我看到一些日志消息，就像第一次尝试一样。

来自文档文件夹的第三个播放列表，播放列表包含完整路径。

 player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:[NSString stringWithFormat: @"%@/playlists/Playlist.a60df6084e7d38b12f84afc602bb39ef.m3u",documentsFolderPath]]];

m3u

但是，如果我直接从没有播放列表的文件夹或服务器播放视频 - 一切都很好。

player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:[NSString stringWithFormat: @"%@/videoContent/1.82aa02198c0255eddc1e538c184c176b.mov",documentsFolderPath]]];

如果我使用 m3u-all 播放来自外部视频流服务器的播放列表也很好。

player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL URLWithString:@"http://devimages.apple.com/iphone/samples/bipbop/gear3/prog_index.m3u8"]];

发生了什么？我不知道。

// You've already got the full path to the documents directory here.
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"/one.mp4"];
// Now you're appending the full path to the documents directory to your bundle path
NSString *mediaPath = [[[NSBundle mainBundle]resourcePath] stringByAppendingPathComponent:filePath];

然后将您的播放器实例更改为：

_moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:filePath]];
[[_moviePlayer view] setFrame:[[self view] bounds]];

[[self view] addSubview: [_moviePlayer view]];

 _moviePlayer.scalingMode = MPMovieScalingModeAspectFit;

[_moviePlayer play];

有同样的问题，在设置 SourceType 后尝试设置 ContentURL，如下所示，

moviePlayerController_ = [[MPMoviePlayerViewController alloc] init];
moviePlayerController_.movieSourceType = MPMovieSourceTypeStreaming;
[moviePlayerController_.moviePlayer setContentURL:url];
