Albumart.py - displays mpd album art

Question

I love ncmpcpp but, sadly, it does not display all the beautiful album art I've collected. So I wrote this little Python script  (75 lines) that does just that.
Here's a demo: http://a.pomf.se/wlozbq.mp4
It monitors mpd and searches for an image in the directory of the currently playing file, but you have to tell it mpd's music directory (MUSICDIR). You set PATTERN as how your album art is named, in globbing format. In my case that's Folder.* for Folder.jpg or Folder.png
It also needs a default image (DEFAULTIMG) in case it doesn't find any album art.
It then displays that image and scales it to the window size. The image proportions are kept, so it might fill some space with a background color that you can set (BGCOLOR).
Close the window to quit.
It requires python-mpd2 from the AUR, python-pillow and tk. I'm not an enterprise programmer so forgive me if the code is shitty. In any case, it's simple and light.
#!/usr/bin/env python
# Requires python-mpd2, python-pillow, tk
from tkinter import Tk, Frame, Label
from PIL import ImageTk, Image
from threading import Thread
import mpd, sys
import glob, re
# Required variables
MUSICDIR = "/home/rolf/Music/"
PATTERN = "Folder.*"
DEFAULTIMG = "/home/rolf/.icons/defaultimg.png"
BGCOLOR = "#1c1c1c"
# Frame class that draws an image and zooms it to the window size
class ImageFrame(Frame):
def __init__(self, master, imgPath, *pargs):
Frame.__init__(self, master, *pargs)
self.img = Image.open(imgPath)
self.origImg = self.img.copy()
self.bgImg = ImageTk.PhotoImage(self.img)
self.bg = Label(self, image=self.bgImg, background=BGCOLOR)
self.bg.pack(fill="both", expand="yes")
self.bg.bind('<Configure>', self._resize_image)
def _resize_image(self, event):
s = min(event.width, event.height)
self.img = self.origImg.resize((s, s), Image.ANTIALIAS)
self.bgImg = ImageTk.PhotoImage(self.img)
self.bg.configure(image=self.bgImg)
def change_image(self, imgPath):
self.img = Image.open(imgPath)
self.origImg = self.img.copy()
self.bg.event_generate('<Configure>', width=self.winfo_width(), height=self.winfo_height())
# Connect with mpd server
try:
client = mpd.MPDClient()
client.connect("localhost", 6600)
except(mpd.ConnectionError):
print("Could not connect to MPD. Exiting.")
sys.exit(1)
# Function to look for albumart according to PATTERN in MUSICDIR/<song's directory>/
def get_albumart(song):
albumArt = DEFAULTIMG
if(song != "STOPPED"):
aaDir = re.sub(r"[^/]*$", "", song["file"])
for albumArt in glob.glob(MUSICDIR + aaDir + PATTERN):
break
return(albumArt)
# The window
root = Tk()
root.title("album art")
imgFrame = ImageFrame(root, get_albumart(client.currentsong()))
imgFrame.pack(fill="both", expand="yes")
# Function that monitors mpd for changes and if so, makes the ImageFrame redraw
def poll():
currentSong = client.currentsong()
while True:
client.idle("player")
previousSong = currentSong
currentSong = client.currentsong()
if(client.status()["state"] == "stop"):
currentSong = "STOPPED"
if(previousSong != currentSong):
imgFrame.change_image(get_albumart(currentSong))
# Start shit up
Thread(target=poll, daemon=True).start()
root.mainloop()

Answer 1

Since that simple script of r6 was so helpful for me, I thought it only fair for me to provide my tweak to it.
Mods:
* Fetched from albumart.org
* Uses directory path for search information
* downloads larger image instead of thumbnail
* works with find -exec {} to auto populate all directories
Here is a link to my simple write up
I just run the following in the root of my music directory
find . -type d -exec ./get_coverart {} \;
And a copy of the script
#!/bin/bash -e
# get_coverart.sh
# This simple script will fetch the cover art for the album information provided on the command line.
# It will then download that cover image, and place it into the child directory.
# The term "album information" is really the relative path of the final directory.
# get_coverart <relative-path>
# get_coverart Tonic/Lemon Parade
# get_coverart Tonic/Lemon\ Parade
# get_coverart Tonic/Lemon_Parade
# To auto-populate all directories in the current directory, run the following command
# find . -type d -exec ./get_coverart "{}" \;
dpath="$1"
encoded="$(perl -MURI::Escape -e 'print uri_escape($ARGV[0]);' "$dpath")"
# Skip already processed ones
if [ -f "$dpath/cover.jpg" ]
then
echo "$dpath/cover.jpg already exists"
exit
fi
echo ""
echo "Searching for: [$1]"
url="http://www.albumart.org/index.php?srchkey=$encoded&itempage=1&newsearch=1&searchindex=Music"
echo "Searching ... [$url]"
coverurl=`wget -qO - $url | xmllint --html --xpath 'string(//a[@title="View larger image" and starts-with(@href, "http://ecx.images-amazon")]/@href)' - 2>/dev/null`
echo "Cover URL: [$coverurl]"
wget "$coverurl" -O "$dpath/cover.jpg"
