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.
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.
Try the free FStream iPhone app http://www.sourcemac.com/?page=fstream that can handle mms, asf, wmv, asx and ogg
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.
