Hi streamer of Locustream!!
you will probably find this useful, specially for the mix of streams!
a new free software is born: IceStream - https://sourceforge.net/projects/icestream/
it's a beta version, we are writing the known bugs & todo, some parts are in french but it is already possible to use it to mix audio streaming, to start an icecast from gui and the to send an audio stream to it or elsewhere. Thanks to mplayer, ices, icecast, vorbis and jack.
It works with jackd server and use only ogg for the moment (we don't use mp3 anyway here).
Of course, we are looking for beta-tester and more people are also welcome to help, support, develop and more if you want!!
mailing list on its way and forum already in place : https://sourceforge.net/apps/phpbb/icestream/
bug tracker to come ;-)
cheers
Julien
