Pasek nastroju

The Moodbar shows you the "mood" of a track, which you can then use to figure out when something interesting happens in the song.

In order for Amarok to display moodbars for your music, you will need the Moodbar program (see below for downloads and binary packages).

The Moodbar package requires GStreamer and various plugins depending on the filetypes you use (see Supported filetypes). You will not need the phonon-backend-gstreamer package to create .mood files.

There are two parts to the new Moodbar implementation: the Moodbar package, which contains a program that takes a music file and generates a .mood file, and support code in the Amarok source, which runs the binary and displays the Moodbar. The Moodbar package depends on the GStreamer libraries. Without the Moodbar package, Amarok cannot generate the moodbars for your music.

As an alternative, there is a new script which will create moodbar files for tracks in an Amarok playlist; this is an exception to the above. The script needs nothing but Amarok to work, but it only creates the .mood files as they are played in the Playlist.

The Moodbar is due to the work of Gavin Wood and Simon O'Keefe, who designed the algorithms; their original paper is here.

Wymagania

  • The Moodbar binary, in your PATH (it should be listed upon running
    which moodbar
    from a console) — Remember to configure the Moodbar package with proper path, e.g. build and install with commands
    ./autogen.sh --prefix=`pkg-config --variable=prefix gstreamer-1.0` && make && sudo make install
  • The GStreamer 1.0 library and plugins for the formats you want Moodbar to be able to analyse. (An earlier GStreamer 0.10 based version is also still available for some distributions)
  • The Fastest Fourier Transform In The West (fftw.org) FFTW library version 3.0 or above (at least single-precision floating point version - libfftw3f) — If your platform does not provide this for you or you need to compile your own version, remember to configure the FFTW package with
    ./configure --enable-single
  • A version of Amarok with a Use moods option in the General section of the configuration screen. This means 1.4.4 or higher in the 1.4 series or 2.2.2 or higher in the 2.x series.

Information

Systems with package managers should automatically install the GStreamer plugins and FFTW along with the Moodbar package if available; this information is provided mostly for people who want or need to compile from source or manually install packages, or where the distribution specific instructions are outdated and no updated moodbar package is yet available.


Sposób użycia

Currently .mood files must be generated manually. Amarok cannot do it for you. To do this for your entire collection, use the Moodbar File Generation Script described below.

To enable the display of moodbars in Amarok, activate it in the configuration: Settings -> Configure Amarok -> General -> Show Moodbar in Progress Slider. Moodbars should now appear in the track sliders in the player window and Playlist; there will also be a mood field that you may add to your playlist layouts.

Instalacja

Pliki źródłowe
Latest release: moodbar-0.1.4.tar.gz — this is the Moodbar source package, which contains the Moodbar program (which generates .mood files from music files), and a GStreamer plugin that does the work. The Moodbar package needs GStreamer 1.0.* installed, plus the 1.0.* version of various plugins. Be sure to install the Moodbar package into the same prefix as GStreamer — follow the instructions in  the summary of requirements chapter. The 0.1.4 is a a fork of original 0.1.2 sources, updated to use GStreamer 1.0. The old 0.1.2 sources are not reliably available online any more, but packages might be still available for some distributions.

Skrypt do generowania plików Moodbara

Poniżej znajduje się prosty skrypt basha, który doda pliki .mood do całej Twojej kolekcji. Dodaje on pliki do każdego pliku o odpowiednim rozszerzeniu w obecnym katalogu oraz wszystkich podkatalogach, zatem najlepiej jest uruchomić go w głównym katalogu z muzyką.

#!/bin/bash
 DIR=${1:-.}
 LAST=~/.moodbar-lastreadsong
 C_RET=0
 
 control_c()        # run if user hits control-c
 {
   echo "" > "$LAST"
   echo "Exiting..."
   exit
 }
 
 if [ -e "$LAST" ]; then
   read filetodelete < "$LAST"
   rm "$filetodelete" "$LAST"
 fi
 exec 9< <(find "$DIR" -type f -regextype posix-awk -iregex '.*\.(mp3|ogg|flac|wma)') # you may need to add m4a and mp4
 while read i
 do
   TEMP="${i%.*}.mood"
   OUTF=`echo "$TEMP" | sed 's#\(.*\)/\([^,]*\)#\1/.\2#'`
   trap 'control_c "$OUTF"' INT
   if [ ! -e "$OUTF" ] || [ "$i" -nt "$OUTF" ]; then
     moodbar -o "$OUTF" "$i" || { C_RET=1; echo "An error occurred!" >&2; }
   fi
 done <&9
 exec 9<&-
 
 exit $C_RET

Skopiuj i wklej cały skrypt do pliku tekstowego o nazwie moodbar.sh w Twoim katalogu z muzyką i uruchom następujące komendy:

cd /path/to/music
 bash moodbar.sh

Gdyby powyższy sposób nie zadziałał, możesz spróbować:

chmod +x moodbar.sh
 ./moodbar.sh

Dla dużych kolekcji może to wymagać niezwykle długiego czasu! Pamiętaj, że paski nastroju nie pojawią się w Amaroku dopóki Amarok nie przeskanuje ponownie kolekcji. Utworzone pliki mood będą poprzedzone kropkami, lub będą plikami ukrytymi - pamiętaj o tym jeśli nie będziesz mógł znaleźć żadnego z nich.

Poniżej znajduje się oparta na powyższym skrypcie alternatywa dla procesorów wielordzeniowych:

#!/bin/bash
 NUMCPU="$(grep ^processor /proc/cpuinfo | wc -l)"
 
 find . -type f -regextype posix-awk -iregex '.*\.(mp3|ogg|flac|wma)' | while read i ; do
 
        while [ `jobs -p | wc -l` -ge $NUMCPU ] ; do
                sleep 0.1
        done
 
        TEMP="${i%.*}.mood"
        OUTF=`echo "$TEMP" | sed 's#\(.*\)/\([^,]*\)#\1/.\2#'`
        if [ ! -e "$OUTF" ] ; then
                moodbar -o "$OUTF" "$i" &
        fi
 done


Rozwiązywanie problemów

  • If the Moodbar executable gives you a bus error, that almost always means it can't decode (or can't find) your file. Take a look at the supported file types below for ideas on which GStreamer plugins to install. You can also try the command below to test whether GStreamer can decode your file:
    gst-launch-1.0 filesrc location=[file] ! decodebin ! fakesink
  • If you are using the ffmpeg plugin to decode mp3s, you may also receive mysterious bus errors. The solution is to stop using the ffmpeg plugin, as it is extremely buggy — use mad instead.
  • If the Moodbar executable tells you that it can't find an element — i.e., it gives an error message like
    Could not create element of type fftwspectrum, please install it.
    — that usually means that you either don't have the required plugins installed (see the plugin list here), or that you didn't install the Moodbar package in the same prefix as GStreamer. If libmoodbar.so and libgstdecodebin.so are not in the same directory, then Moodbar is not installed in the same prefix as GStreamer. Please read the INSTALL file for instructions on how to configure the moodbar package correctly. Alternatively, if you know what you're doing, it may be easier for you to take a look at the GST_PLUGIN_PATH environment variable.
  • If you're wondering why the Moodbar isn't working, either not working at all or not working for a particular file, run the command below, where [file] is a music file:
    moodbar -o test.mood [file]
    To generate a test image preview, one can use the commandː
    gst-launch-1.0 filesrc location=[file] ! decodebin ! audioconvert ! fftwspectrum ! moodbar height=50 max-width=300 ! pngenc ! filesink location=mood.png
  • If you have multiple versions of GStreamer installed, make sure all of the required plugins are installed for version 1.0.* -- different versions cannot use each other's plugins.
