ruby-on-rails - 在后台转换视频 ROR 3

Question

我在谷歌上搜索了一下，只找到了一个网站来解释如何做到这一点:http://railsonedge.blogspot.com/2009/01/flash-video-tutorial-with-rails-ffmpeg.html?m=0我已经在使用回形针并且已经用它设置了所有东西并且喜欢使用它比这个网站的方式更好。有没有办法在使用回形针跟踪视频状态的同时在后台转换视频？我的 Video.rb 目前:

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, :styles => { 
    :video => { geometry: "800x480>", format: 'webm' },
    :thumb => { geometry: "200x200>", format: 'png', time: 3 },
  }, processors: [:ffmpeg], 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

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

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

end

首先check this answer .对于您要使用的后台作业sidekiq .您将需要处理转换的方法。您将在 sidekiq 的#perform 中调用该方法。在此方法中，您还可以更改状态(只需更改字符串字段值)。
