  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Exit Status with ffmpeg Command in Rails

    25 novembre 2012, par DragonFire353

    I am trying to get uploaded videos to be converted in the background, running windows. I am using :

    gem 'paperclip'
    
gem 'aasm'
    
gem 'delayed_job_active_record'
    
gem 'ffmpeg'

    I was using purely paperclip before and making the user wait and it worked great, now I am having problems with the return of the error status for the command, I have tried editing to possible fix the command wondering if it was failing in the first place but I keep getting :

    undefined method `exitstatus' for nil:NilClass

    no matter what. I've tried looking this up and it's supposedly valid syntax that should work... Also I've commented out the actual spawn do part because I get another error if I leave that in :

    wrong number of arguments

    Does anyone know how to properly get this working ? I've went through a few tutorials that have bits and pieces of what I need but I can't get them working together. Here's what I have so far, lemme know if you need more :

  • ffmpeg error when using non root user

    29 août 2014, par mkern

    I have installed ffmpeg and it works perfect if you are root or using sudo but it errors out when trying to use it as a non-root user. I have performed the same install on a test VPS and it installs without issue so it appears to be isolated to this cPanel server. I haven’t been able to identify why.

    Non-Root :

    I am trying to get uploaded videos to be converted in the background, running windows. Some of what I am using :

    gem 'paperclip'
    
gem 'delayed_job_active_record'
    
gem 'ffmpeg'

    I have edited the registry to allow the ffmpeg command to be ran from anywhere, I get a popup that I assume is ffmpeg because it goes away too quickly, guess the command is wrong so if anyone knows what's wrong with it please let me know. But the real problem is that it just hangs there, it says :

    [2012-12-09 22:47:03] ERROR invalid body size.
    
[2012-12-09 22:47:03] ERROR Errno::ECONNABORTED: An established connection was a

    Does anyone know how to properly get this working ? I've went through a few tutorials that have bits and pieces of what I need but I can't get them working together. Here's what I have so far, lemme know if you need more :

    Model :

    class Video < ActiveRecord::Base
    

    
  belongs_to :user
    
  has_many :comments, dependent: :destroy
    
  attr_accessible :video, :user_id, :video_file_name, :title, :public, :description, :views
    

    
  has_attached_file :video, url: "/users/:user_id/videos/:id/:basename_:style.:extension"
    

    
  #process_in_background :video #causes death
    

    
  validates :video, presence: true
    
  validates :description, presence: true, length: { minimum: 5, maximum: 100}
    
  validates :title, presence: true, length: { minimum: 1, maximum: 15 }
    

    
  validates_attachment_size :video, less_than: 1.gigabytes
    
  validates_attachment :video, presence: true
    

    
  default_scope order: 'created_at DESC'
    

    
  Paperclip.interpolates :user_id do |attachment, style|attachment.instance.user_id
    
  end
    

    
  #before_post_process do |video|
    
   # false if video.status == "converting"
    
  #end
    

    
  def perform
    
    command = <<-end_command
    
      start ffmpeg -i #{ '/public/users/:user_id/videos/:id/:basename_:style.:extension' }  -ar 22050 -ab 32 -s 1280x720 -vcodec webm -r 25 -qscale 8 -f webm -y #{ '/public/users/:user_id/videos/:id/:basename_.webm' }
    

    
    end_command
    
    success = system(command)
    
    logger.debug 'Converting File: ' + success.to_s
    
    if success && $?.exitstatus.to_i == 0
    
      #self.converted!
    
      self.status = "converted"
    
    else
    
      #self.failure!
    
      self.status = "failed"
    
    end
    
  end
    

    
  handle_asynchronously :perform

    if search
    
      find(:all, conditions: ["public = 't' AND title LIKE ?", "%#{search}%"], order: "created_at DESC")
    
    else

    end

    if search
    
      find(:all, conditions: ['title LIKE ?', "%#{search}%"], order: "created_at DESC")
    
    else
    
      find(:all, order: "created_at DESC")
    
    end
    
  end
    

    
  private
