MPMoviePlayerController& .m3u8播放列表 [英] MPMoviePlayerController & .m3u8 playlist

问题描述

我想在MPMoviePlayerController中使用包含远程mp4文件的.m3u8播放列表，你有没有成功？

I would like to use a .m3u8 playlist containing remote mp4 files with MPMoviePlayerController, did you success with this ?

1. .m3u8是否必须包含.ts文件？
   如果不是.ts的目的是什么？

1. Does the .m3u8 must contain .ts file ?
   If not what is the purpose of .ts ?

下一个/上一个按钮是否会启用一次要加载播放列表吗？

如果没有，这些按钮的用途是什么？

Does next / previous buttons will be enable once the playlist be loaded ?
If not, what is the purpose of these buttons ?

最后一个问题，你有吗？ m3u8样本文件与远程mp4文件进行测试？

And last question, do you have a .m3u8 sample file with remote mp4 file to test ?

非常感谢您的帮助。

推荐答案

因为你在谈论 .m3u8 和 .ts 文件，我可以假设您对iPhone OS 3.0和Snow Leopard支持的HTTP Live Streaming感兴趣吗？有关HTTP Live Streaming的更多信息，请参阅文档。

Since you're talking about .m3u8 and .ts files, can I assume you're interested in HTTP Live Streaming, as supported by iPhone OS 3.0 and Snow Leopard? There is more info about HTTP Live Streaming in the documentation.

1. 在HTTP直播中， .m3u8 文件列出要按顺序下载和播放的其他文件。如果 .m3u8 文件不包含＃EXT-X-ENDLIST 指令，则客户端假定源是一个实时流，并定期重新提取 .m3u8 以查找要下载的新媒体文件。 .ts 文件是包含多路复用音频和视频的MPEG-2 trasnsport流文件（尽管传输流是MPEG-2规范的一部分，内容应该是是H.264和AAC，音频和视频编解码器通常与MPEG-4相关联。您有时会看到其他内容，例如 .aac ，仅用于纯音频流。服务器会将视频流分段为多个 .ts 个文件， .m3u8 文件将为这些<$提供网址c $ c> .ts 文件，客户端将按顺序下载并播放 .ts 文件。作为iPhone开发人员，您所要做的就是将 .m3u8 URL提供给 MPMoviePlayerController ，它将处理休息。


2. 不知道上一个/下一个按钮...看起来他们在流上下文中没有意义，我不确定是否 MPMoviePlayerController 甚至可以显示它们。您可以使用 movieControlMode 属性来设置向用户提供的控件。


3. Apple的 docs 提供一些样本测试模式流的链接。

1. In HTTP Live Streaming, the .m3u8 file lists other files that are to be downloaded and played in order. If the .m3u8 file doesn't contain an #EXT-X-ENDLIST directive, then the client assumes the source is a live stream, and periodically re-fetches the .m3u8 to find new media files to download. The .ts files are MPEG-2 trasnsport stream files that contain muxed audio and video (despite the fact that the transport stream is part of the MPEG-2 spec, the contents should be H.264 and AAC, the audio and video codecs usually associated with MPEG-4). You sometimes see other contents, like .aac for audio-only streams. A server will segment a video stream into many .ts files, the .m3u8 file will provide URLs for these .ts files, and a client will download and play the .ts files in order. As an iPhone developer, all you have to do is provide the .m3u8 URL to the MPMoviePlayerController, which will handle the rest.
2. Don't know about the prev/next buttons... don't seem like they'd make sense in a stream context, and I'm not sure whether the the MPMoviePlayerController even shows them. You can use the movieControlMode property to set what controls are offered to the user.
3. Apple's docs provide links to some sample test pattern streams.
