  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • Anomalie #3272 : Double # dans l’attribut action du formulaire

    4 octobre 2014, par cedric -

    Oui le fix est bien utile, au moins tant qu’il restera des IE7 dans la nature. De mémoire il était aussi touché par le bug que IE6, il faudrait vérifier si IE8 l’est aussi.
    Ici le vrai bugfix c’est de modifier le formulaire concerné et d’utiliser |ancre_url pour mettre l’ancre car on ne sait jamais ce que action peut contenir en effet.

  • Paperclip-ffmpeg not working on Rails

    28 juillet 2013, par Lee7355512727

    I installed Paperclip-ffmpeg and tried to upload a flv file, but it seems there are some problems converting the file.

    I added Paperclip.options[:command_path] = "/usr/bin/" (I got the path by using which ffmpeg) to my config/environments/development.rb file, following the instructions on the paperclip-ffmpeg github page.

    Here is my model subquestion.rb, which contains a paperclip field called qflv :

    class Subquestion < ActiveRecord::Base
    
    belongs_to :question
    
    has_many :qimages , :dependent =>  :destroy
    

    
    has_attached_file :qflv, styles: {
    
        medium: {geometry: "640*480", format: 'flv'},
    
        thumb: {geometry: "100*100#", format: 'jpg', time: 10}
    
    }, processors: [:ffmpeg]

    And here is my _subquestion_fields.html.erb file, where users upload videos :

    <%= f.file_field :qflv %>

    _subquestion_fields.html.erb is rendered by question.html.erb file :

    <%= nested_form_for @question, :url => {:action => 'create_question'} do |f| %>
    
       <%= f.fields_for :subquestions do |builder| %>
    
       <%= render 'subquestion_fields', :f => builder %>

    And here is part of the error message :

    There might be some problems with pkcs11 so I found this article :

    But I could not find /etc/xdg/autostart/gnome-keyring-*.desktop.
