m3u8流媒体只是在播放iOS 7时获得音频

Question

您好我正在尝试在xcode5 iOS 7.1中播放流式直播视频HLS我正在使用以下代码

NSURL *movieFile = [NSURL URLWithString:@"http://streaming.tlsur.net:1935/blive/ngrp:balta.stream_all/playlist.m3u8"];
player = [[MPMoviePlayerViewController alloc] initWithContentURL:movieFile];
[self presentMoviePlayerViewControllerAnimated:player];
[player.moviePlayer play];

当我将其运行到模拟器中时，它会抛出此错误

kind = 1;
new = 2;
old = 0;

如果我在我的设备中运行它不会抛出_itemFailedToPlayToEnd但我只能获得音频

任何人都知道发生了什么事？
