IceS v2 is not a graphical application, it's purpose is to stream whatever it is given into a stream for feeding to the Icecast streaming server. It does however require the following:
Please note that in many cases, pre-built packages are split into two, a run-time package, typically consisting of the actual run-time library and a development package, consisting of the support files needed to compile and link the application.
The following are optional
IceS reads audio data from an input and sends the audio data to one or more files or icecast servers. Before it's actually sent out, some processing maybe performed, typically resampling and/or downmixing to produce streams suited to various bandwidth requirements.
The streams produced are Ogg Vorbis streams so while icecast 2 is capable of streaming these streams, other streaming servers may not be.
Several inputs currently exist, but some maybe dependant on certain platforms or if certain drivers or libraries are available.
The configuration of IceS is done via an XML based config file. Which you supply as an argument to the program at invocation time. For example
