• Transcodeit Add metadata to audio files

  22 avril 2016, par Gismmo

  I have found how to encode audio tracks to multiple formats, I am just struggling to try and find a way to attach specific metadata to the tracks when they are encoded. I would like to add, album artwork, artists name, track name, and genre etc.

  I can see in the audio encoding parameters there are additional FFmpeg parameters you can set, however i am unsure what to use in order to set the metadata ?

• Load processed video instead of original video - Rails, Dragonfly

  1er février 2016, par Michael B

  In my Rails 4-Project, I am using Dragonfly to upload images and videos.
  For image-processing I use imagemagick, for videoprocessing I use ffmpeg.

  Videos are uploaded and stored in the folder uploads/videos. After processing, they are stored in public/ffmpeg_videos/

  My question is : How can I use the processed-video instead of the uploaded video ?

  e.g. I use this code in the view, to display a video :

  <video src="&lt;%=@video.video.url%>"></video>

  This successfully loads the original video from the upload-path. But what do I have to change, to load the video from the ffmpeg-path ?

  initializers/dragonfly.rb

  require 'dragonfly'
  
  
  
  # Configure
  
  Dragonfly.app(:images).configure do
  
    plugin :imagemagick
  
    protect_from_dos_attacks false
  
    secret 'd045734b043b4383a246c5c8daf2d3e31217dc8b030f21861e4fd16c4b72d382'
  
    url_format '/media/:job/:name'
  
  
  
    datastore :file,
  
              root_path: Rails.root.join('uploads/images/'),
  
              server_root: Rails.root.join('uploads')
  
  end
  
  
  
  Dragonfly.app(:videos).configure do
  
    secret 'd045734b043b4383a246c5c8daf2d3e31217dc8b030f21861e4fd16c4b72d382'
  
    url_format "/video/:job/:name"
  
  
  
    datastore :file,
  
              root_path: Rails.root.join('uploads/videos/'),
  
              server_root: Rails.root.join('uploads')
  
  end
  
  
  
  # Logger
  
  Dragonfly.logger = Rails.logger
  
  
  
  # Mount as middleware
  
  Rails.application.middleware.use Dragonfly::Middleware, :images
  
  Rails.application.middleware.use Dragonfly::Middleware, :videos
  
  
  
  # Add model functionality
  
  if defined?(ActiveRecord::Base)
  
    ActiveRecord::Base.extend Dragonfly::Model
  
    ActiveRecord::Base.extend Dragonfly::Model::Validations
