A very minimalistic Tkinter GUI for playing web radio streams. Meant to be used on a Raspberry Pi with a touchscreen TFT display (like the watterott RPi display [that's what we use] or the adafruit PiTFT display, both 320x240), running Raspbian and an X server (no SDL/Pygame). Tkinter and LXDE on the Raspberry Pi model B+ don't use much resources, so that's OK.
See screenshots/ for some images.
There is no connection to icecast servers, so no search by genre etc. Also, we use mplayer for playing streams instead of mpd and mpc.
Start the radio with:
./player.pyThe default playlist is
~/.raspi-radio/streams.jsonwhich looks like this:
[
{"name": "soma 80s",
"url": "http://ice.somafm.com/u80s"},
{"name": "soma groove",
"url": "http://ice.somafm.com/groovesalad"},
...
] We store the last played stream in last_stream.json and automatically start that the next time.
Copy all files to the raspi:
[me@mybox ~/.../git/raspi-radio]$ scp -r * raspi:raspi-radio/
[me@mybox ~/.../git/raspi-radio]$ scp ~/.raspi-radio/streams* raspi:.raspi-radio/(... or clone the repo).
On the raspi, make sure that the radio starts up when X comes up, but not when we log in via ssh. We use an Xsession startup script:
pi@raspi ~/raspi-radio $ sudo cp 200raspi-radio /etc/X11/Xsession.d/
pi@raspi ~/raspi-radio $ sudo chmod ugo+r /etc/X11/Xsession.d/200raspi-radioInstall desktop icon if you wish:
pi@raspi ~/raspi-radio $ cp desktop/icon-raspi-radio-white.png ~/.icons/
pi@raspi ~/raspi-radio $ cp desktop/raspi-radio.desktop ~/Desktop/./player.pySee also player.py -h, start.sh and 200raspi-radio for how to actually use it, including automatic start after boot.
Icons are an adapted version of http://www.flaticon.com/free-icon/volume-bars-player-music_477 (creative commons license http://creativecommons.org/licenses/by/3.0/legalcode). We added a white background (the original was transparent).
Download the Raspbian image from https://github.com/watterott/RPi-Display, then flash onto the sd card which you will put into the raspi later:
sudo dd if=2014-06-20-wheezy-raspbian-2014-07-25-fbtft-rpi-display-rev2.img of=/dev/mmcblk0Connect to ethernet, boot and ssh into the raspi:
ssh pi@192.168.1.104(IP from dhcp, static IP based on MAC address). Run:
sudo raspi-configChoose "Enable Boot to Desktop/Scratch" -> "Desktop Log in as user 'pi' at the graphical desktop". Choose "Expand Filesystem".
