5.7 Playlists - Format - Conversions - Rhythmbox - Solving the problem of moved files

Formats: 
m3u : just a list of file location, Comments allowed with #
xfpf : a standard xml

Rhythmbox uses its own xml format for playlists.
Backup the playlist file : ~/.share/rhythmbox/playlists.xml

Thanks to python scripts found here http://ubuntuforums.org/showthread.php?t=1740610  you can convert rhythmbox xml file to a lists of m3u files

### Content of file rhythmboxplaylist2exaile:

5.15 Configure pulseaudio for Debian - Iceweasel Soud problem

%%%% Curent config, that seem to work:
%%% For skype
pulse pulse pulse
%%% Pulse input device
Internal Audio Analog Stereo -> Analog Line In(set as fallback ???, don't put it to silence!!!!) 
(With headset Analog Microphone will work )

%%% /etc/pulse/daemon.conf
high-priority = yes
nice-level = -11

realtime-scheduling = yes
realtime-priority = 5

%%% Xfce application autostart
I desactivate pulseaudio
%%% Daemon started at boot (will warn because of per user settings) 
/etc/init.d/pulseaudio 
(update-rc.d pulseaudio defaults)

% The other option is not to start the daemon at boot, and use xfce autostart. 
% As it is, the sound will be such that skype goes cuts rhythmbox. It was not like this before..It's probably because now they go through /usr/lib/i386-linux-gnu/libsndfile.so

%%%# Introduction
The problem comes when several applications try to access the sound device directly.
There are two options :
- Use a mixer between the application and the hardware (pulseausio, or jack)
- Use the hardware mixer with an pplication like dmix provided alsa

Pulseaudio does this mixing job, and thus, allow playing of several applications at the same time.
Pulseaudio, starts by default, if called properlly by the application.

So let's try with pulseaudio which is now default in debian and ubuntu. Several people remove pulseaudio and don't have trouble...well, let's take the challenge.

# Firefox/Iceweasel/Flash player
vlc & rhythmbox together, no problem, they call pulseaudio.
The problem comes from iceweasel or maybe just the flashplugin which try to access the sound device directly.
If pulseaudio is called first, then iceweasel does not have access to the card  /dev/snd/*.
If iceweasel is called first and then pulseaudio, it's pulseaudio that can't access the card.

To see who is using what:
lsof -w | egrep 'snd|dsp'

Use this command extensively to debug: if you see that firefox-bin uses /dev/snd/* then, it will obviously not work. The only one that should use it is pulseaudio!

Below I give my solution, but I recently discovered this official page that could help (though it made things worse for me do to the gstreamer configuration) : http://pulseaudio.org/wiki/PerfectSetup 

%%% The solution that worked for me:
#(Step 0: As I was quite uncertain of my last install of flashplayer, I did a clean install, but this is not necessary
- Purged flashplugin-nonfree*
- Removed ~/.mozilla/plugins/flashplugin*.so  (not sure about the name anymore)
- locate flashplugin* to see if everuthing was purged correctly
- install flashplugin-nonfree and that's all
note for upgrade: sudo update-flashplugin-nonfree --install
)

#Step 1 : install all the pulseaudio stuff:
sudo aptitude install pulseaudio libao4  libpulse-mainloop-glib0 pulseaudio-module-jack pulseaudio-module-hal pulseaudio-module-x11 gstreamer0.10-pulseaudio pulseaudio-utils libasound2-plugins libpulse-browse0 pulseaudio-esound-compat libpulse0 

If you want to use bluetooth: pulseaudio-module-bluetooth 
If you want to use some visual interface stuff: pavumeter paprefs pavucontrol  
!!! PAVUCONTROL is really good. For instance, for recording audio card flux. Launch recording with audacity. then in pavucontrol /recording change internal to monitor in the audacity line.

#Step 2: Tell ALSA applications to use a "pulse" device.
Create/Edit file ~/.asoundrc (or /etc/asound.conf ) with the following content:

pcm.pulse {
    type pulse
}

ctl.pulse {
    type pulse
}

pcm.!default {
    type pulse
    # If defaults.namehint.showall is set to off in alsa.conf, then this is
    # necessary to make this pcm show up in the list returned by
    # snd_device_name_hint or aplay -L
    hint.description "Default Audio Device"
}

ctl.!default {
    type pulse
}
Note, I added the following for skype, but then I commented it, I'm not sure it was usefull: 
#pcm.dmixout {
#    type pulse
#}

This will create a pseudo-device called "pulse" that will be used by default by ALSA applications

#Step3: Make sure you have pcm(mixing) volume none zero
In terminal you can use alsamixer (I had to use the option -c 0) or aumixer, or probably the pulse audio commandline pacmd. 
or whatever volume mixer interface like xfce4-mixer, or the pulse audio one if you installed it.

#Step4: Test
Kill all applications using sound, including pulseaudio. The command lsof -w | egrep 'snd|dsp' should return nothing.
Do some testing. Hopefully you should be able to have youtube/vlc/rhythmbox working all together at the same time for a good cachophony.

%%% Wait, now I'm having a trouble, rhythmbox does not launch pulseaudio by itself
On some website they advise to configure gstreamer to set it to use pulsesink and pulsersrc. But this actually made things crash for me, rhythmbox or totem won't start pulse automatically. 
 
%What they suggests and that make things didn't work (maybe I'm missing a package or something): 
gconftool-2 -t string --set /system/gstreamer/0.10/default/audiosink pulsesink
gconftool-2 -t string --set /system/gstreamer/0.10/default/audiosrc pulsesrc
gconftool-2 -t string --set /system/gstreamer/0.10/default/musicaudiosink pulsesink
%What worked for me is to set everything as auto
gconftool-2 -t string --set /system/gstreamer/0.10/default/audiosink autoaudiosink
fconftool-2 -t string --set /system/gstreamer/0.10/default/audiosrc autoaudiosrc
gconftool-2 -t string --set /system/gstreamer/0.10/default/musicaudiosink autoaudiosink

%%%
In the file /etc/iceweasel/iceweaselrc, replace the line ICEWEASEL_DSP="none" by ICEWEASEL_DSP="aoss"
aoss is a simple wrapper script which facilitates the use of the ALSA OSS compatibility library.
To install it :
root@localhost:~#apt-get install alsa-oss

Does it work??

5.16 Custom filetypes in geany

# to make it really custon, you need to comnpile one...
Otherwise use an existing parser(perl C, LaTeX) and customize it

# First step
launch Geany,Tool>>Configuration files>>filetype_extensions.conf
Add the line
Bib=*.bib;

and saved in ~/.config/geany/filetype_extensions.conf 

cp /usr/share/geany/filetypes.latex /home/manu/.config/geany/filetypes.bib.conf

5.17 Indexation - Search in pdf

#
swish++ appear as a good solution, it is configurable via a .conf file

instead of using a conf file, one can use do it manually
convert all pdf to txt via pdftotext
then index them with index++
then search with search++

#
Use tracker... it's easier and more complete
tracker-control -s    : To launch the indexing:
tracker-preferences   : for options
tracker-search-tool   : for graphical interface
tracker search bla    : command line search
tracker search -t bla : search in documents

5.18 OCR Text recognition and searchable PDF

Idea:
- splitting pdf
- converting to good image format (1bpp )
- use an OCR tool to create hOCR data (html OCR)
- use hocr2pdf to put the text data into the pdf
- combine the pdf (using pdfjoin from pdfjam)

%%% Step by step tools

# pdftk

# pdf2ppm 

# Creating hocr files from images
- tesseract (you need version 3 not 2.04 as in Debian see below)

- cuneiform
cuneiform -l language -f hocr -o output.hocr infile.ppm

# hocr2pdf : puts hOCR data into the pdf (behind images)
hocr2pdf comes with exactimage
-i inputfile
-o output pdf
-n : no image, allows to skip the image normally shadowing the text to either save storage space or take a look how exactly the glyphs are positioned.
-s : sloppy text can improve copy paste text

example:
hocr2pdf -i scan.tiff -s -o test.pdf < cuneiform-out.hocr

#chmod +x jre-6u1-linux-i586.bin

J'ai exécuté le fichier à l'aide de la commande suivante :
#./jre-6u1-linux-i586.bin

Un répertoire nommé jre1.6.0 vient d'être créé. J'ai déplacé ce répertoire dans le répertoire /opt qui va contenir toutes les applications utilisateurs propriétaires.
#mv -f jre1.6.0_01/ /opt/

J'ai ajouté les liens vers les binaires nécessaires à l'aide des commandes suivantes :
#ln -s /opt/jre1.6.0_01/bin/java /usr/local/bin/java
#ln -s /opt/jre1.6.0_01/bin/policytool /usr/local/bin/policytool

J'ai renseigné le reste du système que la Java Runtime Environment est installée en ajoutant la ligne suivante au fichier /etc/environment
#echo JAVA_HOME=/opt/jre1.6.0_01 >> /etc/environment

Création de lien vers libjavaplugin_oji.so

5.32 PDF Croping - suppression d'espace de marges

% Now, I'm using bliss a java application

#Utiliser pdfcrop (script perl d'Eric Doviak et Mark Sherry) disponible sur source forge

#Sinon, pour avoir la taille (old stuff)
identify x.pdf
Puis
convert -crop 10+10+0+0 x.pdf y.pdf

# Recently : I found it to work by first converting to png with a density chosen (between 100 and 300 depending) 
for i in *.pdf ; do convert -density 150 $i tmp/${i%.*}.png;  done
identify *    (gives W0xH0)
concert -crop W2xH2+L2+T2 +repage x.png y.png
Option +repage is important, it remove the canvas information, set it to the new image size.

#convert -crop 950x1160+280+160 +repage x.png y,png

-Virer la ponctuation : tr -d '[:punct:]'
-Virer les lignes avec des caracteres qui ne sont pas des lettres(tab, nombres...) : grep -v '[^a-z]'
-Virer les mots de moins de 2 lettres et les lignes vides:  grep -E '[a-z]{3,}' 
-Mettre tout en lower case :  tr '[:upper:]' '[:lower:]'
-Virer les mot communs :
   grep -v -E -w 'the|and|for|from|with|used'
-Trier avec sort
-Compter les occurences avec uniq et l'option -c : uniq -c
-Trier par nombre reverse: sort -rn

5.35 Aspirer un site avec wget

http://forum.ubuntu-fr.org/viewtopic.php?id=78954

wget -r -l1 -k -E -A *svg http://www.openclipart.org/user-cliparts/johnny_automatic?page=$i

wget -r -l5 -k -E -np www.unsite.com

       `--no-parent' Do not ever ascend to the parent directory when
       retrieving recursively.  This is a useful option, since it guarantees
       that only the files _below_ a certain hierarchy will be downloaded.
       see "Directory-Based Limits", for more details.

Explication :

-r : récursif sur le site
-l5 : cinq niveaux de récursion au maximum
-k : convertir les destinations des liens pour une lecture locale
-E : convertir les types de fichier au format HTML (pour éviter que la lecture de sites en PHP ne foire en lecture sous Firefox).
-np: --no-parent' Do not ever ascend to the parent directory
-A : +list of file types patterns
-c : continue previously stopped download

---------

Pour aller plus loin.

Si vous voulez plus d'options, la page de manuel de wget est pleine d'infos utiles, voici des options très intéressantes :
-t : spécifier combien de fois que wget devrait essayer de télécharger chaque fichier.
-w : spécifier combien de temps attendre entre les essais
-c : demander à wget de continuer un téléchargement interrompu.
-T : spécifier au bout de combien de secondes sans réponse wget abandonne une connexion
--limit-rate : mettre une vitesse de connexion maximale pour ne pas monopoliser votre bande passante
-Q : limiter la place que prendront tous les fichiers téléchargés, pour ne pas trop remplir votre disque dur. Dès qu'à la fin d'un téléchargement le quota sera dépassé, wget s'arrêtera
--load-cookies : importer des cookies (pratique pour les sites où vous devriez être authentifié)
-X : exclure un répertoire

mogrify -resize 800x600 *.JPG
mogrify -resize 50% *.JPG
mogrify -negate test.jpg
mogrify -monochrome test.jpg
mogrify -format jpg *.png
mogrify -scale 110x2 *.png  # wouldn't work with 110x1

#Animation Gif
convert -delay 20 -loop 0 sphere*.png animation.gif
animate *.gif

convert fig13.png -crop 1530x1210+75+95 test.png

5.43 Installer un nouveau pager : most

better than more or less
     Le pager est un programme qui sert à afficher du texte. Vous avez le choix entre plu-
sieurs programmes, grâce à un mécanisme d'alternatives. Je vous propose d'installer
et d'utiliser most, un pager qui permet entre autres de colorer les pages de manuel.
# aptitude install most
# update-alternatives --config pager
     La seconde commande vous demnde de choisir le pager à utiliser. Répondez en
donnant le numéro qui correspond à most. Maintenant, c'est ce programme qui sera
utilisé pour afficher les manuels.
