+Q. After requesting CDDB data, I received several answers which seem to be
+ quite alike. Can I find out the difference between some of them?
+A. Yes. When asked which one you want to select, use "X,Y" where X and Y are
+ the numbers of the selections you want to find the difference between.
+
+Q. I don't like CDDB/FreeDB. How can I use Musicbrainz instead?
+A. Set CDDBMETHOD=musicbrainz and try it!
+
+
+4. abcde and Album Art
+ ===================
+
+Q. Can abcde download album art?
+A. As of abcde 2.6.1 it is possible to download a suitable cover
+ image from within abcde that can be used by applications such
+ as Audacious and vlc to illustrate playback with an album cover.
+ Many hardware playback devices such as iPODs will also use this
+ image during playback and show it on the device's display.
+
+Q. How does album art downloading work?
+A. The details are contained in abcde within a new function called
+ 'getalbumart' which can be called either from the commandline or
+ from within an ~/.abcde.conf file. The technique works in 3 possible
+ ways:
+
+ 1. If CDDBMETHOD is musicbrainz the album art is downloaded from
+ coverartarchive by MBID (MusicBrainz Identifier)
+ 2. If 1 fails, download is tried from amazon by ASIN (Amazon
+ Standard Identification Number)
+ 3. If if 1 and 2 fail or CDDBMETHOD is cddb the album art will
+ be downloaded using glyrc by artist + album title
+
+ You will need to install your distro's package of glyr, a music
+ related metadata search engine, and it is strongly advised that
+ you use 'musicbrainz' for your cddb lookups. To access the more
+ advanced features of getalbumart it is also strongly advised that
+ you install the ImageMagick package of your distro. getalbumart
+ will work without ImageMagick but functionality will be reduced.
+
+Q. What settings and options should I select?
+A. If you want to operate abcde from the commandline only you will
+ get reasonable results with something like either of the following:
+
+ abcde -o mp3:-V2 -a default,getalbumart
+ abcde -o mp3:-V2 -G
+
+ But to experience all of the options of getalbumart you should also
+ consider setting the following in your ~/.abcde.conf file:
+
+ #----------------------------------------------------------------#
+ CDDBMETHOD=musicbrainz # Use MusicBrainz for CDDB
+ ACTIONS=default,getalbumart # Select the album art action + default
+
+ # Give the path to the metadata search application glyrc. Add any
+ # glyrc options:
+ GLYRC=glyrc
+ GLYRCOPTS=
+
+ # Give the path to ImageMagick's 'identify' which is used to give a
+ # commandline summary of the album art and also assist in any conversions.
+ # Add any 'identify' options:
+ IDENTIFY=identify
+ IDENTIFYOPTS=
+
+ # Give the path to ImageMagick's 'display' which will show the album art.
+ # The options below are the abcde default, feel free to add your own:
+ DISPLAYCMD=display
+ DISPLAYCMDOPTS="-resize 512x512 -title abcde_album_art"
+
+ # Give the path to ImageMagick's 'convert' which is used to convert album
+ # art to the format specified in ALBUMARTTYPE. Add any 'convert' options:
+ CONVERT=convert
+ CONVERTOPTS=
+ # If you want to run CONVERTOPTS on all files (including those specified
+ # in ALBUMARTTYPE) set the following to "y":
+ ALBUMARTALWAYSCONVERT="n"
+
+ # By default the filename will be cover.jpg and the file format will
+ # be jpeg. 'convert' will automagically change other formats to jpeg:
+ ALBUMARTFILE="cover.jpg"
+ ALBUMARTTYPE="JPEG"
+ #----------------------------------------------------------------#
+
+ There are more hints concerning commandline options in the sample
+ abcde.conf file included with your abcde package. Good news is that
+ the existing defaults will work well without any extra adjustments :).
+
+Q. Can I manually select album art?
+A. If you have set INTERACTIVE=y (this is the default) then you will have
+ the opportunity to manually select the album art of your choice either
+ from online by typing in a URL or by typing in the path to a local file.
+
+Q. What if I want my album art embedded?
+A. The philosophy of getalbumart at the moment is to simply place the album
+ art in the same location as the encoded files. Perhaps this will change
+ one day. In the meantime you can use abcde's post_encode function in
+ your ~/.abcde.conf file to embed the album art. Here is an example for
+ mp3 embedding using eyeD3:
+
+ #----------------------------------------------------------------#
+ post_encode ()
+ {
+ ARTISTFILE="$(mungefilename "$TRACKARTIST")"
+ ALBUMFILE="$(mungefilename "$DALBUM")"
+
+ if [ "$OUTPUTTYPE" = "mp3" ] && [ "$TAGGER" = "$EYED3" ] ; then
+ vecho "Preparing to embed the album art..." >&2
+ else
+ vecho "Not embedding album art, you need mp3 output and eyeD3 tagging..." >&2
+ return 1
+ fi
+
+ if [ "$VARIOUSARTISTS" = "y" ] ; then
+ FINDPATH="$(eval echo "$VAOUTPUTFORMAT")"
+ else
+ FINDPATH="$(eval echo "$OUTPUTFORMAT")"
+ fi
+
+ TRIMPATH="$(dirname "$OUTPUTDIR/$FINDPATH")"
+ cd "$TRIMPATH"
+
+ if [ -e "cover.jpg" ] ; then
+ for i in *.mp3
+ do
+ eyeD3 --add-image cover.jpg:FRONT_COVER "$i"
+ done
+ mkdir backup && mv cover.jpg backup
+ vecho "Your files have had the album art embedded..." >&2
+ else
+ vecho "No album art found so no image embedded..." >&2
+ fi
+ }
+ #----------------------------------------------------------------#
+
+ Variations of the 'for' loop in this example should work for other encoding
+ types. For example with flac:
+
+ #--------------------
+ for i in *.flac
+ do
+ metaflac --import-picture-from=cover.jpg "$i"
+ done
+ #--------------------
+
+ With other appropriate adjustments to the $OUTPUTTYPE and $TAGGER checks of
+ course...
