cTune is a ncurses based internet radio player written in C for Linux.

Aside from playing a radio stream you can search and browse stations as well as keep a list of favourites.

It uses the RadioBrowser API to search and get radio stream information.

• Context-based help for key bindings (F1 key).
• Plugin system for playback (demuxing/resampling) and sound output (PCM)
• UI Themes
• Mouse support

CLI

Usage: ./ctune [OPTION]...

    --debug          prints out all debug messages to the log
-f  --favourite      add station to favourites when used in conjunction with "--play"
-h  --help           display this help and exits
-p  --play "UUID"    plays the radio stream matching the RadioBrowser UUID
-r  --resume         resumes station playback of the last session
    --show-cursor    always visible cursor
-v  --version        prints version information and exits

Application files

*In case you want to find the name of a song/station that you liked and forgot to write down or favourite.

Both the application log and playback log are overwritten when ctune is launched again.

Configuration

Most configuration options are accessible via the options menu.

Dependencies

Installation

Compile from source

Requires the following to be installed on the system first:

• cmake version 3.17 and the CMake extra-modules package
• git for fetching the repos
• ffmpeg, vlc player libraries*
• lame for recording streams to mp3
• curl and openssl libraries
• sdl2 or pulsedaudio or alsa or sndio or pipewire sound library/servers*
• pandoc and gzip for the man page

(*) The relevant plugins will be compiled for whatever libraries can be found on the system.

From there:

1. Clone the repository git clone https://github.com/An7ar35/ctune.git
2. Get in the directory with cd ctune
3. run cmake . -DCMAKE_BUILD_TYPE=Release (append -DCMAKE_INSTALL_PREFIX=</path/to/directory> if you want to specify a custom directory for the installation)
4. run cmake --build .
5. run sudo cmake --install .
6. Done.

To uninstall

Just run sudo xargs rm < install_manifest.txt from within the cloned directory.

Or, alternatively:

• cmake . -DCMAKE_BUILD_TYPE=uninstall
• sudo cmake --build . --target uninstall

Finally, for both approaches, run sudo mandb after to purge the ctune entry for the man database

Install from repository

Arch AUR (x64)

The package is available in the AUR repository under ctune-git. Install using your favourite AUR package browser/installer.

Alternatively just download the PKGBUILD file into an empty staging folder and run makepkg -si from inside. The rest should take care of itself.

Ubuntu 22.10 'Kinetic' (tested with pulseaudio as the default server)

The version of ffmpeg libs packaged with ubuntu 22.04.1 LTS are too old. Since the API changed I've updated the calls in ctune which breaks compilation for older ffmpeg libs.

No PPA but here are copy/paste commands to install all the required programs and development libraries you would need before compiling ctune:

sudo apt-get install gcc libncurses5 git cmake cmake-extras make man pandoc gzip

sudo apt-get install libavcodec-dev libavformat-dev libavutil-dev libswscale-dev libswresample-dev libavdevice-dev libavfilter-dev libssl-dev libcurl4-openssl-dev libncurses5-dev libbsd-dev libpulse-dev lame

For more input/output plugins, install the required lib too. Once all these are on the system compiling from source should work without hiccups.

Docker

Docker is only there for testing purposes and only works on linux with either pulseaudio or pipewire-pulse installed and running. It uses the Arch docker image as base. The docker-compose.sh script creates the container and runs it (final size = ~1GB).

Platform

Linux x64 with a UTF-8 locale.

As a baseline v1.3.2 works on ArchLinux with:

• FFMpeg (libavformat 59.27.100, libavcodec 59.37.100, libswresample 4.7.100)
• VLC (3.0.21)
• Pipewire (1:1.2.2)
• PulseAudio (17.0)
• SDL (2.30.6)
• ALSA (1.2.12)
• sndio (1.7.0)
• OpenSSL (3.3.1)
• Curl (8.9)
• nCurses (6.5)
• libbsd
• lame (3.100)

F.A.Q.

Q. What are the key bindings?

A. Press F1 to get a contextual list of key bindings in the UI.

Q. How do I use the mouse?

A. Check out this guide.

Q. I'm getting weird symbols where the icons are supposed to be. What's going on?

A. Your terminal font does not support the unicode characters used. Either change the font or switch back to ASCII icons from the Options menu.

Q. Can I change the look?

A. Yes. There are internal preset themes available in the Options menu and, if these don't strike your fancy, a custom theme can be specified inside ctune's configuration file.

Bug reporting & Support

Disclaimer: I've writen this software primarily for myself so temper your support-level expectations accordingly.

That being said, if you find a bug you are welcome to open a ticket. I'll try to deal with it time allowing. Same for bug PRs.

For tickets, please include the following to help diagnose the source of the problem:

1. Basic information:
   1. (UI bugs) Terminal/Shell used if it's a UI bug (e.g.: Konsole 21.04 using BASH 5.1.8)
   2. Version of cTune used and what sound output/libraries it was compiled/run against (run ctune --version to get a print out of all that info)
2. Bug description
   1. What seems to break and where
   2. What triggers the bug - how did the bug manifest itself + steps to reproduce it
   3. (UI bugs) A screenshot of the issue
3. Logs and Configuration
   1. Configuration used (see inside ctune.cfg)
   2. The cTune error log (run ctune --debug to generate more granular and useful info during execution)
   3. Copy of the system log's (syslog) cTune runtime specific entries where the bug occurred (output of journalctl --utc -b -0 | grep ctune if you're using systemd)

Thank you.
