Ruby mediainfo find unique properites - ruby

Question

I'm trying to scan a large hard drive (think 17TBs) to find a storage estimate for video files within specific folders. In addition, I am trying to find specific unique properties of the video files. The purpose of this is to make a case for a digital asset management system that can support the video files that we have going back to 2009. I'm using mediainfo to inspect each video.
I have the file size/storage count working, but i'm having trouble adding the hashes of video properties to an array in my loop. My goal is for media info to look at the specific properties of each video, put them into a hash and add that hash to an array. Then, once I have collected all the hashes of video properties, I would call uniq! on the array so that it would show me the unique video properties.
The output of my code currently returns the video properties for the last video over and over again. I can't see what I'm doing wrong. Any advice?

Answer 1

I figured it out. I was creating new hashes outside of the loop. A new hash needed to be created for each iteration so that it could then be added to the video_info array. Then I needed to remove the bang operator when I called uniq on video_info at the end of the script. Here's my final code:
require 'json'
#developed by Maile Thiesen
#!/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"
