Requirements

  • python 2.6+/3.2+
  • MPV, MPlayer or VLC installed and in your path.
  • socat (if you wish to use MPV)

Installation

The best way to install PyRadio is via a distribution package, if one exists (e.g. Arch Linux and derivatives can install pyradio-git from AUR).

In any other case, and since PyRadio is currently not available via pip, you will have to build it from source.

Command line options

$ pyradio -h

usage: pyradio [-h] [-s STATIONS] [-p [PLAY]] [-a] [-l] [-d] [-u USE_PLAYER]

Curses based Internet radio player

optional arguments:
  -h, --help            show this help message and exit
  -s STATIONS, --stations STATIONS
                        Use specified station CSV file.
  -p [PLAY], --play [PLAY]
                        Start and play.The value is num station or empty for
                        random.
  -a, --add             Add station to list.
  -l, --list            List of added stations.
  -d, --debug           Start pyradio in debug mode.
  -u USE_PLAYER, --use-player USE_PLAYER
                        Use specified player. A comma-separated list can be
                        used to specify detection order. Supported players:
                        mpv, mplayer, vlc.

Stations file

PyRadio reads the stations to use from a CSV file (named stations.csv), where each line contains two columns, the first being the station name and the second being the stream URL.

PyRadio will by default use the user's configuration file (e.g. ~/.config/pyradio/stations.csv) to read the stations. If this file is not found, it will be created and populated with a default set of stations.

Tip: If you already have a custom stations.csv file, but want to update it with PyRadio's default one, you just rename it, run PyRadio (so that the default one get created) and then merge the two files.

A different file can be used when the -s command line option is used.

Note: Older versions used to use ~/.pyradio as default stations file. If this file is found, it will be copied to use's config directory (e.g. ~/.config/pyradio) and renamed to stations.csv or if this file exists, to pyradio.csv. In this case, this file will be the default one.

Player detection / selection

PyRadio is basically built around the existence of a valid media player it can use. Thus, it will auto detect the existence of its supported players upon its execution.

Currently, it supports MPV, MPlayer and VLC, and it will look for them in that order. If none of them is found, the program will terminate with an error.

MPV will be used only when the socat multipurpose relay is also installed.

Users can alter this default behavior by using the -u command line option. This option will permit the user either to specify the player to use, or change the detection order.

Example:

pyradio -u vlc

will instruct PyRadio to use VLC; if it is not found, the program will terminate with an error.

pyradio -u vlc,mplayer,mpv

will instruct PyRadio to look for VLC, then MPlayer and finaly for MPV and use whichever it finds first; if none is found, the program will terminate with an error.

Player default volume level

MPV and MPlayer, when started, use their saved (or default) volume level to play any multimedia content. Fortunately, this is not the case with VLC.

This introduces a problem to PyRadio: every time a user plays a station (i.e restarts playback), even though he may have already set the volume to a desired level, the playback starts at the player's default level.

The way to come around it, is to save the desired volume level in a way that it will be used by the player whenever it is restarted.

This is done by typing "v" right after setting a desired volume level.

MPV

MPV uses profiles to customize its behavior.

PyRadio defines a profile called "[pyradio]" in MPV's configuration file (e.g. ~/.config/mpv/mpv.conf). This profile will be used every time playback is started.

Example:

volume=100

[pyradio]
volume=50

MPlayer

MPlayer uses profiles to customize its behavior as well.

PyRadio defines a profile called "[pyradio]" in MPV's configuration file (e.g. ~/.mplayer/config). This profile will be used every time playback is started.

Example:

volume=100

[pyradio]
volstep=1
volume=28

Debug mode

Adding the -d option to the command line will instruct PyRadio to enter Debug mode, which means that it will print debug messages to a file. This file will always reside in the user's home directory and will be named pyradio.log.
