gr-streamsink

A GNURadio sink block to stream the audio to SHOUTcast or Icecast.

Thanks

Thanks to Daniel Nöthen, his code from butt (broadcast using this tool) was very helpful.

Dependencies

GNURadio and the LAME library (libmp3lame-dev) must be installed and you need a SHOUTcast or Icecast server running.

Installation

$ mkdir build
$ cd build
$ cmake ../
$ make
$ sudo make install
$ sudo ldconfig

Usage

The block is available in grc (gnuradio-companion). See the examples directory for some flow graphs and python applications.

Usage in python

Import:

import streamsink
```

Create the sink block:
```
sink = streamsink.streamsink(
        samplerate,         # The input samplerate
        bitrate,            # The mp3 bitrate
        server_type,        # "shoutcast" or "icecast"
        address,            # IP address or hostname of the server
        port,
        password,
        icecast_user,       # Only required if using Icecast
        icecast_mountpoint) # Only required if using Icecast
```

Add additional info and properties for the SHOUTcast / Icecast stream:
```sink.set_stream_public(False)
sink.set_stream_name("Your stream name")
sink.set_stream_genre("Your genre")
sink.set_stream_url("example.org")
sink.set_stream_description("Your description") # Only for Icecast
```
