EZStream

easy media streaming client over icecast servers

http://www.icecast.org/ezstream.php
Ezstream is an audio and video streaming client which feeds any icecast server with audio data and metadata from a standard input without reencoding. It thus requires very little CPU resources. Some playlists can be looped and composed with MP3, Ogg Vorbis or Ogg Theora media files. Shoutcast metadata are also supported.

Vamos criar/editar o Arquivo: ezstream_mp3.xml
