  • bash script to install / update ffmpeg static builds

    1er mars 2017, par Joakim

    Hi I’m trying to make my first "real" bash script to do some real work than can be executed both manually and through cron jobs.

    The script should download and install the ffmpeg-static-build from https://johnvansickle.com/ffmpeg

    Here is what I’ve got so far :

    #!/bin/bash
    
# Still to come, see if the script runs with root privileges else exit
    
#Download FFMPEG static daily build and it's md5
    
cd ~
    
wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz | tar -xf
    
#wget https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5
    
curl -L https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5 | tar -xf | tee -a https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz | cut -d\  -f1 | md5sum > md5sum.txt
    

    

    
#Chech the md5 is currect
    
#md5sum -c MD5SUMS
    
file1="md5sum.txt"
    
file2="ffmpeg-git-64bit-static.tar.xz.md5"
    

    
if ! cmp --silent "$file1" "$file2"; then
    
    echo "md5sum doesn't match...\n exit" >&2
    
    exit 1
    
fi
    

    

    
#tar -xf ffmpeg-*.tar.xz
    
cp ffmpeg-*-static/ff* /usr/bin/
    
cp ffmpeg-*-static/ff* /usr/local/bin/
    
cp ffmpeg-*-static/qt-faststart /usr/bin/
    
cp ffmpeg-*-static/qt-faststart /usr/local/bin/
    
# Consider change second location to use ln -s
    
# Remove downloads and do some clean up
    

    
rm -fr ffmpeg-*
    

    
#EOF

    As you can see in the script i would like to add the md5sum check but it fails (got the md5sum check part from Compare md5 sums in bash script)

    If i remove the md5sum part the script is working, but right now the script fails at the | tar -xf | part with this code

md5sum doesn't match...

    As this is my first, I would appreciate any "I’m 4 years old" advices and why

    update

    Have made some changes to the script based on the suggestions in this thread, but my problem is I have no output what so ever at this state :( So I think it’s time to ask for the next clue

    But still having some issues :(

    1. Running this script returns : a blanc shell, but I’ve expected one of the printf statements
    2. When I’m trying to narrow down the problem and going back to basic and trying to run the script with only the "if" part it fails with 44 : Syntax error : "(" unexpected

    3. running the very same "if" part typed directly into the shell/terminal itself it’s all happy !!
      if diff <(md5sum ffmpeg-git-64bit-static.tar.xz) <(curl -s "https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5"); then printf "%s\n" "No new version availeble" >&2; elif ! diff <(md5sum ffmpeg-git-64bit-static.tar.xz) <(curl -s "https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz.md5"); then rm -f ffmpeg-git-64bit-static.tar.xz; curl https://johnvansickle.com/ffmpeg/builds/ffmpeg-git-64bit-static.tar.xz > ffmpeg-git-64bit-static.tar.xz; printf "%s\n" "Going to install new version" >&2; fi

    4. I’m confused

  • OpenCV compile process fails

    12 septembre 2017, par bork

    So I’m following this post on how to install openCV for Python 3. And I’m running into some issues at the compile process. Running the make -j4 command goes fine up until it’s 28% through when I get this error message : error: use of undeclared identifier 'avcodec_free_frame'; did you mean 'avcodec_get_name'?

    I don’t even know where to start to solve this issue. I’ve got ffmpeg installed through brew.

  • Evolution #3926 : Remplacement de safehtml par le plug htmlpurifier ou autre

    14 janvier 2019, par Guillaume Fahrner

    Sorry je n’avais pas vu ce message :

    cedric - a écrit :

    Depuis https://core.spip.net/projects/spip/repository/revisions/24131 le plugin HTMLPurifier est fonctionel sans nécessiter de patch dans le core ?

    Malheureusement si : il reste une surcharge de la fonction propre() via inc/texte.php. Elle est utilisée pour réaliser la protection HTML via echappe_html() AVANT le 1er filtrage de sécurité via echapper_html_suspect(). Un deuxième est réalisé via echappe_retour_modeles($t, $interdire_script) ou $interdire_script est vrai en espacé privé ou si le mode parano actif et faux sinon. (Je n’ai pas su faire autrement, mais il y a peut être une astuce a trouver.)

    Je ne sais pas si tu considères que c’est le core mais une surchage des règles YAML de textwheel est également réalisé afin que l’on envoi bien tout qui doit l’être dans les filtres de sécurité.

    Donc non pas de modification du core nécessaire pour que le plugin fonctionne. A voir si ces surcharges mériterais une "intégration directe" future.

    on est bon et on peut release tel quel en indiquant que le plugin htmlpurifier est disponible pour tests et se laisser le temps ?

    A mon avis oui. Pour rappel : le mode parano est actuellement inutilisable avec l’actuel safehtml(). Du coup ça peut être une approche pour l’intégrer/le tester au fil de l’eau : commencé par les gens qui utilisent le mode parano en leur recommandant chaudement/forcant ce plugin.

    Ci dessous la liste des plugins que j’utilise sans problème hors textwheel/todo (cf https://core.spip.net/issues/4254) avec htmlPurifier :

    Todo 2.2.1 - stable
    Traduction entre rubriques 3.1.3 - stable
    YAML 1.5.4 - stable

    Je pense que si on doit intégrer le plugin ça sera sur la version dev 3.3, pas sur la version stable, et ça va demander de prendre le temps de voir toutes les modifs et les impacts éventuels que tu n’aurais pas vu ou auxquelles tu n’aurais pas pensé.

    Clairement je pense me faire insulter :-) Je suis prêt ^^ Plus sérieusement il faut absolument tester/restester/reretester. J’ai tenté de faire au mieux mais je ne peux pas revoir tout le code HTML généré par les plugins... Au moindre écart de conformité HTML ca ne passera pas. Le bug https://core.spip.net/issues/4254 en est un bon exemple : avec htmlpurifier l’élément

    est supprimé ; avec "safehtml() standard" le code invalide est conservé et c’est le navigateur qui va corriger.

    Il faut voir les bons cotés : cela force les bonnes pratiques, met SPIP au plus haut niveau du standard (Drupal fait moins bien), aide a identifier des bugs et ce qui passe dans propre() sera obligatoirement valide. C’est aussi a terme moins de problèmes d’injection XSS a traiter pour la team.

    Sur la fonction de survol des logos le sujet reste ouvert ? On est en effet d’accord que cette écriture est obsolète et devrait être revue de toute façon, mais c’est donc un point à traiter dans le core le cas échéant

    Euh je comprend pas, faut-il intégrer le patch des puces de statut dans ce plugin ? Je pensais plus coder le truc """proprement""" avec un JS dans le directement dans /prive/. A décolérer complètement à mon sens.

    Encore merci pour le temps que tu y passes :)
