在iOS中实现HTTP Live Streaming [英] Implementation of HTTP Live Streaming in iOS
问题描述
我想写一个小小的iOS视频客户端，并且必须使用HTTP Live Streaming。视频来自支持HTTP直播流的Wowza媒体服务器，因此服务器端实现不是我的问题。
我已经观看了WWDC视频并阅读了关于HTTP Live Streaming的Apple文档。
I want to write a little iOS video client and have to use HTTP Live Streaming. The videos come from a Wowza Media Server which supports HTTP Live Streaming, so the server-side implementation is not my problem. I have already watch the WWDC videos and read the Apple documentation about HTTP Live Streaming.
但无处可解释如何在iOS设备上播放视频。在WWDC-talk中提到有3个拥有来显示视频：
But there is nowhere explained how to play back the videos on an iOS device. In a WWDC-talk was mentioned that there are 3 possebilties to display the videos:
- UIWebView
- MPMoviePlayerController
- AVPlayerItem
哪一个最好？
我怎样才能从HTML-Page这样的HTML页面中读出视频URL，由服务器提供？
And how can I read out the video-URL's from a HTML-Page like these, which become provided by the server?

我真的不知道从哪里开始编码...也许有人知道比恼人的缝合流播放器更好的示例代码，或者可以编写一个小教程... p>
I really don't know where to start with coding...Maybe somebody know better example code than the annoying "Stitched Stream Player" or can write a little tutorial...
推荐答案
一个简短的点对点实现。包含的网址指向一个有效的流（截至2015年12月15日），但您可以将自己的网址替换为.m3u8文件。
A short and to the point implementation. The included URL points to a valid stream (as of 12/15/2015), but you can just replace with your own URL to a .m3u8 file.
Objective-C：
Objective-C:
#import <MediaPlayer/MediaPlayer.h>
@interface ViewController ()
@property (strong, nonatomic) MPMoviePlayerController *streamPlayer;
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *streamURL = [NSURL URLWithString:@"http://qthttp.apple.com.edgesuite.net/1010qwoeiuryfg/sl.m3u8"];
_streamPlayer = [[MPMoviePlayerController alloc] initWithContentURL:streamURL];
// depending on your implementation your view may not have it's bounds set here
// in that case consider calling the following 4 msgs later
[self.streamPlayer.view setFrame: self.view.bounds];
self.streamPlayer.controlStyle = MPMovieControlStyleEmbedded;
[self.view addSubview: self.streamPlayer.view];
[self.streamPlayer play];
}
- (void)dealloc
{
// if non-ARC
// [_streamPlayer release];
// [super dealloc];
}
@end
Swift：
import UIKit
import MediaPlayer
class ViewController: UIViewController {
var streamPlayer : MPMoviePlayerController = MPMoviePlayerController(contentURL: NSURL(string:"http://qthttp.apple.com.edgesuite.net/1010qwoeiuryfg/sl.m3u8"))
//Let's play
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
streamPlayer.view.frame = self.view.bounds
self.view.addSubview(streamPlayer.view)
streamPlayer.fullscreen = true
// Play the movie!
streamPlayer.play()
}
}
更新了两种语言的答案。另外，在iOS 9中不推荐使用 MPMoviePlayerController ，但可以使用 AVPlayerViewController 。快乐编码。!!!
Updated answer for both the languages. Also MPMoviePlayerController is deprecated in iOS 9, but you can use AVPlayerViewController instead. Happy Coding.!!!
