Ezstream is a command line source client for media streams, primarily for streaming to Icecast servers.
It allows the creation of media streams based on input from files or standard input that is piped through an optional external de- and encoder. As every part of this chain is highly configurable, ezstream can be useful in a large number of streaming setups.
It uses libshout to communicate with streaming servers and currently supports Ogg, MP3, WebM, and Matroska streams using the HTTP, ICY, and RoarAudio protocols. It uses TagLib to read and manage metadata in numerous media files.
Ezstream is free software and licensed under the GNU General Public License.
COPYING file for details.
Ezstream depends on:
- libshout version 2.2.x or newer
- libxml version 2.x
- TagLib for C version 1.x (1.4 or newer recommended)
Ezstream optionally uses:
- libiconv on systems where
iconv()is not available in libc, for basic non-ASCII charset support in metadata and filenames
Building ezstream depends on:
- check unit testing framework for C
- pkg-config or compatible replacements
- GNU make in case the system make(1) does not work
Developers of ezstream also need:
The ezstream software uses the GNU auto-tools to configure, build, and install on a variety of systems. Several (additional) configuration options are available.
./configure --help to get an overview.
The compilation and installation process then boils down to the usual
$ ./configure --help | less # Skim over the available options $ ./configure [options] && make && [sudo] make install # Configure, build and install # [as root] the software
If this procedure is unfamiliar to you, please consult the
INSTALL file for
more detailed instructions.
On systems where the libshout installation does not include the required
shout.pc file for
pkg-config(1), the non-standard
is available. However, the ezstream build system does not support the latter.
If this is an issue, configure ezstream with
$ ./configure \ LIBSHOUT_CPPFLAGS="$(shout-config --cppflags)" \ LIBSHOUT_CFLAGS="$(shout-config --cflags-only)" \ LIBSHOUT_LIBS="$(shout-config --libs)"

Once ezstream is installed successfully, type
man ezstream on the command

example configuration files that can be used as a guide to configure
As ezstream is a source client, a media streaming server like Icecast must be available to distribute the stream to listening clients. See (https://www.icecast.org/) for more information and resources.
Ezstream should be able to work with any media decoder and encoder that fulfills the following requirements:
- Must be an executable that can be run from the command line without the need for a graphical display or terminal
- Decoding software must be able to either
- write raw audio data to standard output, or
- write a properly encoded stream ready for distribution to standard output
- Encoding software must be able to read raw audio data from standard input
The following incomplete list of programs shows a few that are known to work. These are also used in the example configuration files:
Ogg Vorbis (https://xiph.org/vorbis/):
- Decoder: oggdec
- Encoder: oggenc
- Decoder: flac
- Encoder: flac (requires Ogg FLAC output)
- Decoder/Encoder: ffmpeg2theora (http://v2v.cc/~j/ffmpeg2theora/)
