  In paperclip processors folder i have ffmpeg.rb file also.

  my model

  class product < ActiveRecord::Base
  
      has_attached_file :video, :styles => {
  
      :mp4video => { :geometry => "640x480", :format => 'mp4', :convert_options => {:output => {:ar => 44100}} },
  
      :webmvideo =>{ :geometry => "1024x576", :format => 'webm', :convert_options => {:output => {:ar => 44100}} },
  
      :oggvideo => { :geometry => "1024x576", :format => 'ogg', :convert_options => {:output => {:ar => 44100}} },
  
      :thumb => { :geometry => "100x100#", :format => 'jpg', :time => 10 }
  
    },
  
    :storage => :s3,
  
    :s3_credentials => "#{Rails.root}/config/aws.yml",
  
    :processors => [:transcoder]
  
  
  
    process_in_background :video

• mp4,m4v vidoes not play on firefox

  20 novembre 2015, par Waqas Ahad

  Using paperclip-ffmpeg for video uploading in Rails.
  It plays on Chrome but not on Firefox and throws :

  Video format or MIME type is not supported

  I have this code in my model :

  has_attached_file :videod, :styles => { 
  
                          medium => { :geometry => "640x480", :format => 'mp4' },
  
                         :thumb => { :geometry => "100x100#", :format => 'jpg', :time => 10 }
  
  }, :processors => [:ffmpeg]
  
  validates_attachment_size :videod, :less_than => 100.megabytes
  
  validates_attachment_presence :videod
  
  validates_attachment_content_type :videod, :content_type => /\Avideo\/.*\Z/

  I also installed ubuntu-restricted-extras which was required to play it on firefox.

• How to run .mp4 videos on firefox

  19 novembre 2015, par Haseeb Ahmad

  When play mp4 videos on chrome it works fine.But same videos not playing on firefox. After some search I found this

  Firefox does not support .mp4 playback. Try conveting the video to .ogg format which is fast becoming a standard format for html 5 applications.

  Now how I convert this to ogg for firefox.
  My model code is

  has_attached_file :videod, :styles => { 
  
    :medium => { :geometry => "640x480", :format => 'mp4' },
  
    :thumb => { :geometry => "100x100#", :format => 'jpg', :time => 10 }
  
  }, :processors => [:ffmpeg]
  
  validates_attachment_size :videod, :less_than => 100.megabytes
  
      validates_attachment_presence :videod
  
      validates_attachment_content_type :videod, :content_type => /\Avideo\/.*\Z/
