Raf has a released an early WIP Radio app for the PSP, heres the details:
I've been working on getting an internet radio client for the PSP.
I want it to support shoutcast servers, and for starters support MP3 format.
I'll worry about the interface later.
I got a C++ framework all set up already. This will allow people to develop applications for the PSP with sound/networking support a lot easier to do.
I got the networking to work too. (The profile is selectable via a config file, along with the mp3 file/stream(url)).
More.. I got the app in a state where it can play an mp3 file perfectly, and also an mp3 stream from a URL!!!!
More things to do (In no particular priority order)
-Nicer user interface
-Support for v1 playlists
-Support for v2 playlists
-Metadata retrieval (display song title from a online stream)
-ID3 tag parsing
-AAC support
-better shoutcast server support
-more configuration availability (buffers, etc)
Heres also the latest version news:
-I have playlist (v1) support working now.
-If anybody knows of a free hosting service with subversion support (like sf.net but with subversion instead of cvs), please let me know.
