We should fully document our main source protocol - which is a slightly
modified HTTP, but haven't. Sorry about that. I'll cover it later in this
The other protocols are supported solely for backwards compatibility with
older systems - you should refer to documentation for those systems for
For icecast 2, the primary source protocol is HTTP, with one modification: a
new HTTP method, "SOURCE", is introduced. When a SOURCE request is received,
icecast2 adds the incoming stream as a mountpoint using the request-URI in
the SOURCE request. The request must be authenticated using HTTP BASIC auth.
That's all there it to it!
There's also some stuff for compatibility with other systems (icecast 1.x,
shoutcast) for mp3 metadata - this isn't documented by us either, but is
widely documented elsewhere (search for 'mp3 shoutcast metadata protocol').
