可以在iPhone上流式传输mms,ASX,RTSP流吗? [英] Is that possible to stream mms,ASX,RTSP stream on iPhone?
问题描述
我正在开发一个音乐流应用程序。
I am developing one music streaming application.
我可以使用描述的方法流式传输mp3 此处。有没有人知道使用Core Audio或其他框架传输其他格式(ASX,RTSP或mms)的方法。
I can stream mp3 using a method described here. Does anybody know approach to stream other formats(ASX, RTSP or mms) using Core Audio or other framework.
提前致谢。
推荐答案
mms,ASX和RTSP在历史上是一些专有协议(特别是微软和真实的),因此您可能无法找到官方的苹果实现。
mms, ASX, and RTSP are historically somewhat proprietary protocols (by microsoft and real, in particular), so you may have trouble finding an official apple implementation.
这里有一个mms协议的LGPL实现: https:// launchpad。 net / libmms
或者您可以从microsoft获取协议的文档: http://download.microsoft.com/download/9/5/E/95EF66AF-9026-4BB0-A41D-A4F81802D92C/ %5BMS-MMSP%5D.pdf
There's a LGPL implementation of the mms protocol here: https://launchpad.net/libmms Or you can get the documentation for the protocol from microsoft here: http://download.microsoft.com/download/9/5/E/95EF66AF-9026-4BB0-A41D-A4F81802D92C/%5BMS-MMSP%5D.pdf
ASX只是XML中的元数据格式;你用它来获取流式传输的mms或http URL。官方参考资料在微软网站上: http://msdn.microsoft.com /en-us/library/bb249663.aspx
ASX is just a metadata format in XML; you'd use it to get a mms or http URL to stream from. The official reference for it is on microsoft's site: http://msdn.microsoft.com/en-us/library/bb249663.aspx
RTSP在这里有一个LGPL实现: http://www.live555.com/liveMedia/
这是一个标准协议( RFC 2326 和 RFC 3550 )但是显然经常与Real的RDT传输一起使用专有扩展,所以如果你能够再使用一个库可能会更容易。
RTSP has an LGPL implementation here: http://www.live555.com/liveMedia/ It's a standard protocol (RFC 2326 and RFC 3550) but is apparently often used with proprietary extensions such as Real's RDT transport, so again it might be easier to just use a library if you're able.
