Paperclip::Av::Qtfaststart

Fix FFmpeg MP4 video files.

Installation

Add this line to your application's Gemfile:

gem 'paperclip-av-qtfaststart'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paperclip-av-qtfaststart

Usage

When FFmpeg produces mp4 files, it places the moov atom at the end which makes it unstreamable.

To fix this, use this processor to run qtfaststart after transcoding the video file using ruby-av/paperclip-av-transcoder

In your model:

class Lesson < ActiveRecord::Base
  has_attached_file :video, :styles => {
    :mobile => {:geometry => "400x300", :format => 'mp4', :streaming => true}
  }, :processors => [:transcoder, :qtfaststart]
end

See danielgtaylor/qtfaststart for instructions on how to setup qtfaststart.
