Ruby mediainfo 找到独特的属性

Question

我正在尝试扫描一个大硬盘驱动器（想想 17TB），以查找特定文件夹中视频文件的存储估计值。此外，我正在尝试查找视频文件的特定独特属性。这样做的目的是为数字资产管理系统提供一个案例，该系统可以支持我们追溯到 2009 年的视频文件。我正在使用 mediainfo 来检查每个视频。

我的文件大小/存储计数正常工作，但我无法将视频属性的哈希值添加到循环中的数组中。我的目标是让媒体信息查看每个视频的特定属性，将它们放入散列并将该散列添加到数组中。然后，一旦我收集了视频属性的所有哈希值，我就会调用 uniq！在阵列上，以便它向我展示独特的视频属性。

我的代码的输出当前一遍又一遍地返回最后一个视频的视频属性。我看不出我做错了什么。有什么建议吗？

require 'yaml'

video_info = []

files_list.each do |filepath|
filename = File.basename(filepath.to_s)
  filepath.chomp!

我想通了。我在循环之外创建了新的哈希值。每次迭代都需要创建一个新的散列，然后可以将其添加到 video_info 数组中。然后，当我在脚本末尾的 video_info 上调用 uniq 时，我需要删除 bang 运算符。这是我的最终代码：

require 'json'

#!/usr/bin/ruby

library_path = ARGV[0]

files_list = Dir.glob("#{library_path}/**/*")
total_capture_scatch_and_exports_size = 0
counter = 0

video_info = []

files_list.each do |filepath|
filename = File.basename(filepath.to_s)
  codecs = {}
  filepath.chomp!
  folders_to_scan = ["/capture scratch/", "/capturescratch/", "/capture-scratch/", "/capture_scratch/", "exports", "export"]

  file_size = File.size(filepath)
  file_extension = File.extname(filepath)
  if 
      folders_to_scan.any? { |folder| filepath.downcase.include? folder }

      if 
          File.file?(filepath) && filename[0] != "." && file_extension != ".TIFF" && file_extension != ".TIF" && file_extension != ".tif" && file_extension != ".tiff" && file_extension != ".jpg" && file_extension != ".jpeg" && file_extension != ".JPG" && file_extension != ".JPEG"
              duration = %x[mediainfo --Inform="General;%Duration/String3%" '#{filepath}'].chomp!
              format = %x[mediainfo --Inform="General;%Format%" '#{filepath}'].chomp!
              commercial_name = %x[mediainfo --Inform="General;%Format_Commercial_IfAny%" '#{filepath}'].chomp!
              format_profile = %x[mediainfo --Inform="General;%Format_Profile%" '#{filepath}'].chomp!
              writing_library = %x[mediainfo --Inform="General;%Encoded_Library%" '#{filepath}'].chomp!

              codecs[:format] = format
              codecs[:commercial_name] = commercial_name
              codecs[:format_profile] = format_profile
              codecs[:writing_library] = writing_library
            codecs[:file_extension] = file_extension    
            total_capture_scatch_and_exports_size += file_size

            counter += 1
            video_info << codecs
      end    

  end

end
puts "THE UNIQUE CODECS ARE: #{JSON.pretty_generate(video_info.uniq)}"
puts "THE TOTAL FILESIZE IS : #{total_capture_scatch_and_exports_size/(1000**3).to_f} GB"
