• Rails : Encoder error when converting video using FFMPEG on Heroku

  2 janvier 2013, par andmcgregor

  I'm trying to upload a video and convert the file to mp4 and reduce the file size using the paperclip-ffmpeg and paperclip gems. Everything works fine running a local server and I'm only getting this problem on heroku. I have ffmpeg installed in vendor/ffmpeg/ (I followed these steps : https://gist.github.com/3963576). Here is the code I've got and the error I'm getting :

  models/video.rb :

  class Video < ActiveRecord::Base
  
    attr_accessible :content, :user_id, :video
  
    has_attached_file :video , :styles => { 
  
      :medium => { :geometry => "500x500", :format => 'mp4',
  
          :convert_options => { :output => { :vcodec => 'libx264',
  
          :b => '1000k', :bt => '200k',
  
          :acodec => 'libfaac', :ab => '56k', :ac => 2 } } }
  
    }, :processors => [:ffmpeg]
  
  
  
    belongs_to :user
  
  end

  when I run heroku logs :

  Everything works fine until the message Unknown encoder 'libx264' so I'm thinking it's something to do with ffmpeg perhaps ?

• Background Video Processing with Rails

  23 octobre 2013, par Matthew Snyder

  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.

  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 :
