=== Pasek nastroju ===


''Pasek nastroju'' oficjalnie powraca w '''Amaroku''' 2.2.2. Jest to narzędzie do wykrywania "nastroju" utworu, które pozwala zobaczyć w którym miejscu piosenki dzieje się coś ciekawego.
The ''Moodbar'' shows you the "mood" of a track, which you can then use to figure out when something interesting happens in the song.


Aby '''Amarok''' analizował twoje pliki muzyczne pod kątem nastroju, potrzebny będzie program '''Moodbar''' (poniżej informacje o pobieraniu [[#Source Downloads|plików źródłowych]] oraz pakietów binarnych).   
In order for '''Amarok''' to display moodbars for your music, you will need the '''Moodbar''' program (see below for [[Special:myLanguage/Amarok/Manual/Various/Moodbar#Source Downloads|downloads]] and binary packages).   


Pakiet '''Moodbar''' wymaga ''GStreamera'' oraz różnych pluginów, zależnie od tego, jakich typów plików używasz (zobacz: [[#Supported Filetypes|Obsługiwane pliki]]). Pakiet phonon-backend-gstreamer '''nie''' będzie potrzebny do tworzenia plików .mood.
The '''Moodbar''' package requires '''GStreamer''' and various plugins depending on the filetypes you use (see [[Special:myLanguage/Amarok/Manual/Various/Moodbar#Supported Filetypes|Supported filetypes]]). You will ''not'' need the phonon-backend-gstreamer package to create .mood files.


Nowa implementacja '''Moodbara''' składa się z dwóch części: pakietu '''Moodbar''', który zawiera program generujący pliki .mood dla utworów oraz dodatkowego kodu w źródle '''Amaroka''', który włącza i wyświetla pasek nastroju. Pakiet '''Moodbar''' wymaga biblioteki ''GStreamer''. Bez pakietu '''Moodbar''' Amarok nie będzie analizował nastroju Twojej muzyki.  
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.  


Alternatywą jest nowy skrypt, który może tworzyć pliki Moodbara dla utworów na liście odtwarzania '''Amaroka'''. Stanowi on wyjątek od powyższych wymagań - do działania nie wymaga niczego poza Amarokiem, jednak tworzy pliki .mood tylko dla plików z ''listy odtwarzania''.
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'''.
 
''Moodbar'' istnieje dzięki Gavinowi Woodowi oraz Simonowi O'Kneefe, którzy stworzyli potrzebne algorytmy. Ich oryginalną pracę można znaleźć [http://cratoo.de/amarok/ismir-crc.pdf tutaj].  


The '''Moodbar''' is due to the work of Gavin Wood and Simon O'Keefe, who designed the algorithms; their original paper is [http://cratoo.de/amarok/ismir-crc.pdf here].

==== Wymagania ====
==== Wymagania ====


* Wykonywalny plik '''Moodbar''' w PATH (powinien wyświetlić się po wpisaniu {{Input|1=which moodbar}}w konsoli) -- pamiętaj o konfigurowaniu '''Moodbara''' z {{Input|1=./configure --prefix=`pkg-config --variable=prefix gstreamer-0.10`}}
* The '''Moodbar''' binary, in your PATH (it should be listed upon running {{Input|1=which moodbar}}from a console) &mdash; Remember to configure the '''Moodbar''' package with proper path, e.g. build and install with commands {{Input|1=./autogen.sh --prefix=`pkg-config --variable=prefix gstreamer-1.0` && make && sudo make install}}


* Biblioteka ''GStreamer'' 0.10 i [[#Supported Filetypes|pluginy]] dla formatów, z którymi będziesz używał '''Moodbara'''.
* The GStreamer 1.0 library and [[Special:myLanguage/Amarok/Manual/Various/Moodbar#Supported Filetypes|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)


* Biblioteka ''Fastest Fourier Transform In The West'' (http://www.fftw.org) ''FFTW'' w wersji 3.0 lub wyższej (numer wersji z co najmniej jednym miejscem po przecinku - libfftw3f) -- Jeśli Twój system nie zapewnia tej biblioteki, lub potrzebujesz skompilować własną wersję, pamiętaj by konfigurować z {{Input|1=./configure --enable-single}}
* The ''Fastest Fourier Transform In The West'' ([http://www.fftw.org fftw.org]) FFTW library version 3.0 or above (at least single-precision floating point version - libfftw3f) &mdash; If your platform does not provide this for you or you need to compile your own version, remember to configure the  FFTW package with {{Input|1=./configure --enable-single}}


* Wersja '''Amaroka''' z opcją <menuchoice>Pokaż pasek nastroju</menuchoice> w sekcji Ogólne w menu konfiguracji. To znaczy wersja 1.4.4 lub wyższa dla serii 1.4 lub 2.2.2 lub wyższa dla serii 2.x.
* A version of '''Amarok''' with a <menuchoice>Use moods</menuchoice> option in the <menuchoice>General</menuchoice> 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.


{{Info/pl|Systemy zawierające menedżer pakietów powinny automatycznie instalować pluginy ''GStreamer'' oraz ''FFTW'' razem z '''Moodbarem'''. Powyższa informacja jest zamieszczona głównie dla osób, które chcą lub muszą skompilować program ze źródła lub ręcznie zainstalować pakiety.}}
{{Info|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 ====
==== Sposób użycia ====


Obecnie pliki .mood są generowane ręcznie. Aby dokonać tego dla całej swojej kolekcji użyj [[#Moodbar File Generation Script|skryptu do generowania plików Moodbara]] opisanego poniżej.
Currently .mood files ''must'' be generated manually. '''Amarok''' cannot do it for you. To do this for your entire collection, use the [[Special:myLanguage/Amarok/Manual/Various/Moodbar#Moodbar File Generation Script|Moodbar File Generation Script]] described below.


Aby włączyć wyświetlanie pasków nastroju w '''Amaroku''', zaznacz odpowiednią opcję w menu konfiguracyjnym: <menuchoice>Ustawienia -> Konfiguruj -> Ogólne -> Pokaż pasek nastroju w suwaku postępu</menuchoice>. Pasek nastroju powinien się teraz pojawić w suwaku postępu w oknie odtwarzacza i w oknie playlisty. Pojawi się także pole "nastrój", które będziesz mógł dodać do swoich szablonów list odtwarzania.
To enable the display of moodbars in '''Amarok''', activate it in the configuration: <menuchoice>Settings -> Configure Amarok -> General -> Show Moodbar in Progress Slider</menuchoice>. 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.

==== Skrypt do generowania plików Moodbara ====


Here is a simple bash script that will add .mood files to your entire collection. It adds mood files for all files matching the extensions in the current directory and all subdirectories, so it's best run from the base of your music directory.  
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.  


{{Input|1=
{{Input|1=
Line 150: Line 148:
  exit $C_RET</syntaxhighlight>}}
  exit $C_RET</syntaxhighlight>}}


Copy and paste the above into a text file named moodbar.sh in your music directory and run the following commands:
Skopiuj i wklej cały skrypt do pliku tekstowego o nazwie moodbar.sh w Twoim katalogu z muzyką i uruchom następujące komendy:
<!--}}-->{{Input|1=
<!--}}-->{{Input|1=
  cd /path/to/music
  cd /path/to/music
Line 156: Line 154:
}}<!--{{-->
}}<!--{{-->


Alternatively if the above does not work, you may try:
Gdyby powyższy sposób nie zadziałał, możesz spróbować:
<!--}}-->{{Input|1=
<!--}}-->{{Input|1=
  chmod +x moodbar.sh
  chmod +x moodbar.sh

}}<!--{{-->
}}<!--{{-->


This may take a very long time for large collections! Note that the moodbars will not appear in '''Amarok''' until '''Amarok''' rescans the collection. The generated <tt>mood</tt> files will be dotfiles (i.e., prefixed with a full stop), or hidden files - so keep this in mind if you can't find any generated mood files.
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 <tt>mood</tt> będą poprzedzone kropkami, lub będą plikami ukrytymi - pamiętaj o tym jeśli nie będziesz mógł znaleźć żadnego z nich.

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.

    ./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.

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.

Obsługiwane typy plików

You will need various Gstreamer plugins to enable Moodbar to analyze your files. Here is a list of the plugins you will need; make sure to install the 1.0.* version of each plugin:

Filetype Required Plugin Note
All gstreamer-1.0.*, gst-plugins-base, gst-plugins-good
mp3 gst-plugins-mad (in gst-plugins-ugly) ffmpeg plugin has problems; do not use for mp3
ogg gst-plugins-vorbis, gst-plugins-ogg
flac gst-plugins-flac
mp4 gst-plugins-faad, gst-plugins-bad
musepack gst-plugins-musepack
wma gst-plugins-ffmpeg
