• Unable to upload/convert videos using Paperclip-FFMPEG gem in Rails

  31 juillet 2012, par Graeme

  FIXED : It's due to a typo in the relevant lib file that I hadn't spotted ! See this issue for more details.

  ---

  I'm still a bit of a Ruby on Rails newbie (running Rails 3.2.6 and Ruby 1.9.3p194), but I'm finding it very difficult to convert video files using the paperclip-ffmpeg gem. No matter what I do, an error message is displayed on the page after attempting to upload the video :

  "cannot load such file : /[...My info...]/lib/paperclip_processors/ffmpeg.rb"

  I'm trying to test using .mov files for the moment.

  I'm trying to follow the instructions on the gem's github page, but without much success.

  Firstly, I'm using a Mac (Snow Leopard) and ffmpeg is installed (running which ffmpeg tells me it's in /user/local/bin/ffmpeg)

  In my application, I've added the following lines to the gemfile :

  gem 'paperclip'
  
  gem 'paperclip-ffmpeg' 

  I've also added Paperclip.options[:command_path] = "/usr/local/bin/" to config/environments/development.rb as per the instructions :

  Myapp::Application.configure do
  
  
  
  ...
  
  
  
  Paperclip.options[:command_path] = "/usr/local/bin/"
  
  end

  (The instructions also suggest "in your environment config file, let Paperclip know to look there by adding that directory to its path", but I don't know what this means - maybe this is the problem ?).

  My class is structured as follows :

  class Myvideo > ActiveRecord::Base
  
  
  
    attr_accessible :description, :title, :video
  
  
  
    has_attached_file :video, :styles => { 
  
        :medium => { :geometry => "640x480", :format => 'flv' }
  
      }, :processors => [:ffmpeg]
  
  
  
  
  
  end

  My understanding is that the above code converts the uploaded movie from .mov (or whatever) to .flv format.

  However, the error I describe above appears whenever the user clicks on the Upload button (save for a few seconds while the video appears to be uploading).

  Note that I can upload a video via the standard Paperclip gem without converting with no problems. Therefore, this code works (i.e. the video is uploaded but no conversion occurs) :

  attr_accessible :description, :title, :video
  
  
  
    has_attached_file :video

  Any ideas where I might be going wrong ? Thanks !

  ---

  EDIT - the original error message ("Cannot load such file...") appears to have arisen because I hadn't included the relevant ffmpeg.rb file from Github within the /lib directory. Thanks to @wehal3001 for pointing this out !

  However, while I now have this file in my application, I still get the following error when trying to upload a video :

  uninitialized constant Paperclip::Ffmpeg::PaperclipError
  ...
  lib/paperclip_processors/ffmpeg.rb:123:in

  rescue in make'
lib/paperclip_processors/ffmpeg.rb:120:in

  make'
  app/controllers/videos_controller.rb:43:in

  new'
app/controllers/videos_controller.rb:43:in

  create'

  Any help would be much appreciated !

• ffmpeg on Mamp wrong path

  24 août 2012, par user1595349

  I am having some problems with running ffmpeg on a MAMP environment an a Mac. I was able to install ffmpeg with homebrew and i can use it in the terminal with no problems.

  However I am not able to call ffmpeg with MAMP via php exec.

  I'm using this script :

  <?php
  
  exec('ffmpeg -i test.mp3 test.wav');
  
  ?>

  I think something might be wrong with the path ? Do I need to install ffmpeg in the MAMP folder ? At the moment it is installed in my "usr/Users/Username/local/bin" folder...?

  Thank you for your help !
