• 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
  
  end

• avformat/mxfdec : Don't pretend array to be bigger than it is

  11 septembre 2023, par Andreas Rheinhardt

  avformat/mxfdec : Don't pretend array to be bigger than it is
  mxf_match_uid() accepts two const UID and a len parameter.
  
  UID is a typedef for an array of 16 uint8_t, so the const UID
  
  parameter is actually a pointer to const uint8_t.
  The point of mxf_match_uid() is to check whether the initial
  
  part of two UIDs match ; the length of said part is given
  
  by the len parameter. Once an incomplete UID has been passed
  
  to mxf_match_uid() (albeit with the correct len, so safe),
  
  which makes GCC emit -Wstringop-overread warnings.
  Fix this by using a const uint8_t[] as type ; it is more
  
  natural for incomplete UIDs.
