Icecast dev - Jan 2007 - Icecast protocol

Hey there,

I'm writting a simple app which is gonna take FLAC file and convert them 
to ogg and mp3 format before sending them to icecast upon streaming.  I 
have search a lot over and can't find a icecast protocol definition, or 
even an overview anywhere.  Is somebody can point me on this one or I 
have to read the whole icecast source code (I know java but C/C++ is 
another thing...).

Regars.

Hi Ian,

What you're describing is typically the job of the source client, of
which there are already many to chose from. If you're still interested
in making your own I'd probably start with looking at the source for the
ezstream client that's on the icecast website. The source (C/C++) is
stright-forward enough and it makes use of libshout, an implementation
of the shoutcast protocol that icecast supports. In all likelihood it's
what you'll be using to transmit your encoded audio to your icecast
server (there are docs and examples in the libshout tarball on the
icecast website). Aside from C/C++ bindings there are also Perl, Ruby,
and others as well, so if you're comfortable with something else they
may be worth your while.

You'll notice that ezstream makes use of the host operating system's
decoders/encoders and just pipes the output from one to the other then
through libshout and finally to the server. In your case it sounds like
you want to just use the respective format's libraries and do the
decoding/encoding yourself.

If anyone else has anything to add/change, by all means... it's been a bit.

Best of Luck.

In addition to what others have said (which is good advice), I'll
answer your question more directly:

Icecast's protocol is mostly just HTTP. For a source client (what you
want to write), there's a single extension - a SOURCE method.
Semantically, it's rather like PUT.

Really, that's all there is to it!
