goicy - AAC/AACplus/AACplusV2 & MP1/MP2/MP3 Icecast/Shoutcast source client
What's the point?
goicy is a small, portable and fast MPEG1/2/2.5 Layer1/2/3 and AAC/AACplus/AACplusV2 Icecast/Shoutcast source client written in Go. It is written to be extremely light-weight, cross-platform and easy to use. It is a complete rewrite in Go of my old source client called hz and written in Free Pascal: https://github.com/stunndard/hz
How it works?
goicy can work in two modes: ffmpeg and file.
In ffmpeg mode goicy feeds audio files to ffmpeg which recodes them in realtime
to AAC or MP3 format and sends the output to an Icecast or Shoutcast server.
In file mode goicy reads and parses AAC or MPEG (MP1, MP2, MP3) files and sends them to
the server without any further processing.
What files are supported?
In ffmpeg mode: any format of file recognizable by ffmpeg is supported.
In file mode: AAC/AACplus/AACplusV2 and MPEG1/MPEG2/MPEG2.5 LayerI/II/III files
can be streamed to a Icecast or Shoutcast server. All possible bitrates are
fully supported, including CBR and VBR.
Tell me more.
- Any audio files readable by ffmpeg are supported. All possible bitrates and their variations, including VBR.
- Pretty precise timing.
- Icecast and Shoutcast servers are fully supported.
- Metadata updating supported. The metadata is read from ID3v1 and ID3v2 tags. It can also be read from cuesheets (.cue file with the same name as audio file).
What platforms are supported?
Linux and Windows at the moment.
What is required?
ffmpeg configured with --enable-libfdk-aac. Compile your own, or get the static compiled binaries,
for example here: https://sourceforge.net/projects/ffmpeg-hi/
How do I install goicy?
The go get command will automatically fetch all dependencies required, compile the binary and place it in your $GOPATH/bin directory.
go get github.com/stunndard/goicy
How do I configure it?
Read goicy.ini. Tune it for your needs.
[stream]
; stream type
; must be 'file' or 'ffmpeg'
streamtype = ffmpeg
...
[ffmpeg]
; path to the ffmpeg executable
; can be just ffmpeg or ffmpeg.exe if ffmpeg is in PATH
; your ffmpeg should be compiled with libmp3lame and fdk_aac support enabled!
ffmpeg = ffmpeg-hi10-heaac
; sample rate in Hz
; ffmpeg will use its internal resampler
samplerate = 44100
; number of channels
; 1 = mono, 2 stereo
channels = 2
; AAC stream bitrate
bitrate = 192000
; AAC profile
; must be 'lc' for AAC Low Complexity (LC)
; 'he' for AAC SBR (High Efficiency AAC, HEAAC, AAC+, AACplus)
; 'hev2' for AAC SBR + PS (AACplusV2)
aacprofile = lcPrepare your static playlist file, like:
/home/goicy/tracks/track1.mp3
/home/goicy/tracks/track2.flac
/home/goicy/tracks/track3.m4a
/home/goicy/tracks/track4.aac
/home/goicy/tracks/track5.ogg
Mixing different formats in one playlist is perfectly valid in ffmpeg mode!
How about a remote file, or a radio station?
http://your.server/your/music.mp3
https://your.box/your/music.mp4
http://your.icecast.radio/
Any input recognizable by ffmpeg is perfectly valid in ffmpeg mode
So you can easily reencode and relay internet radios too.
In file mode, though, you can only use AAC or MP1/MP2/MP3 files:
/home/goicy/tracks/track1.aac
/home/goicy/tracks/track2.aac
/home/goicy/tracks/track3.aac
/home/goicy/tracks/track4.aac
/home/goicy/tracks/track5.aac
or
/home/goicy/tracks/track1.mp3
/home/goicy/tracks/track2.mp3
/home/goicy/tracks/track3.mp3
/home/goicy/tracks/track4.mp3
/home/goicy/tracks/track5.mp3
All files should be the same format, bitrate, samplerate and number of channels.
Don't mix different format (MPx/AACx) or different samplerate in one playlist if goicy is set to file
mode.
How do I run it?
goicy inifile, i.e.:
./goicy /etc/goicy/rock.ini
