streamTranscoder

About

streamTranscoder Transcodes, and streams audio to a SHOUTcast / Icecast / Peercast server.

Description

This command line application was designed to provide opportunities for broadcasters to support multiple types of formats/bitrates/samplerates for their streams. It will act as both a listener client (for many different types of streams) AND as a source client (for many different types of streaming servers.

Well, maybe a picture will help:

Compatability

Currently the following servers are supported on input (i.e. listens to):

  • Shoutcast - MP3 (with metadata and without)
  • Icecast 1.x - MP3 (with icy metadata and without)
  • Icecast 2 - MP3 (with metadata)
  • Icecast 2 - Vorbis (with metadata)
  • Peercast - MP3 and Vorbis
  • KasterBlaster - MP3 (no metadata)

The following servers are supported on output (i.e. streams to):

  • Shoutcast - MP3
  • Icecast 1.x - MP3 (with icy metadata and without)
  • Icecast 2 - MP3 (no metadata - Icecast2 does not support it at this time)
  • Icecast 2 - Vorbis (with metadata)
  • Peercast - MP3 and Vorbis
  • WMA - win32 ONLY

Supported platforms

streamTranscoder was written with many platforms in mind, and is supported on both win32, and Linux, as well as FreeBSD, and UNIX like systems.

Another note about platform specific stuff. Currently LAME (lame_enc.dll) on win32 and LAME (libmp3lame.so) on UNIX provide a different interface. Most notably is the absense of high/lowpass filters on win32. For this reason you cannot set high/lowpass filters on win32 and you can talk to the LAME maintainers if this displeases you. :) Also, WMA is supported only under win32. This is due to the not-so-obvious fact that no WMA encoder libraries exist for UNIX.

Also, if you are running the win32 version of streamTranscoder, you will also need the WMA format distribution...you can get it here -> http://www.un4seen.com/files/WMFAdist.exe

Library dependencies:

Note that in order to build streamtranscoder, you may need to get the devel versions of the libraries as well. This usually only applies if you are installing the RPM versions of the above libraries.

Installation:

FreeBSD:

Using the ports system:

cd /usr/ports/audio/streamtranscoder make install clean
Using the pkg system:
pkg install audio/streamtranscoder
