是否有可能在iPhone上传输mms，ASX，RTSP流？

Question

I am developing one music streaming application.

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.

Thanks in advance.

Answer 1

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.

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 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 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.

FStream is good for audio. You can also use Streamer for video streaming. It is a good app except that it is not friendly at all. Type the URI mms://server/ in your favorites. Then click on it. You will find a button that says: "Pause". Click that again to read: "Unpause". Then wait for 10-15 seconds, the video will start streaming after that. Make sure that you choose a URI that you know works for sure.
