Is that possible to stream mms,ASX,RTSP stream on iPhone?

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.
