This library is my new approach of a wrapper for the Exiftool command-line application (https://exiftool.org) written by Phil Harvey. The intention is to have a performanter library than mini_exiftool with the possibility to work on multiple files at once.

After reading a directory, multi_exiftool's error contains "17214 image files read", but no actual error.
ARGV.each do |dir|
r = ''
r = '**' if @options[:recursive] == true
allfiles = Dir.glob(File.join(File.expand_path(dir), r, '*.orf'))
next if allfiles.empty?
results, errors = MultiExiftool.read(allfiles)
unless errors.empty?
p errors
raise('Reading exifs failed')
end
endIn irb, I went over each file in that directory and got no error:
allfiles = Dir.glob(File.join(File.expand_path(dir), r, '*.orf'))
allfiles.each do |f|
results, errors = MultiExiftool.read([f])
unless errors.empty?
p errors
raise("Reading #{f} failed")
end
endThis error occurs only in one directory, in the other eight I worked on multi_exiftool behaves as expected.
I get this error any time I try to call .to_json, .to_h, .to_hash on a blob... I can't tell what specificall ymight be causing it but maybe the special japanese characters. (I'm using heroku dynos)

Traceback (most recent call last):

ArgumentError (mon out of range)
Hello!
I have an .ExifTool_config file that defines some custom tags. To use it, the exiftool CLI has the -config option, which must come before all other arguments on the command line. However, when I try to do this with MultiExiftool:
writer = MultiExiftool::Writer.new
writer.options = { 'config' => '/path/to/.ExifTool_config', 'P' => true, 'E' => true }
writer.filenames = file_path
writer.overwrite_original = true
writer.values = valuesThe -config option is always preceded by some -charset options:
=> ["-charset",
"FileName=utf8",
"-charset",
"utf8",
"-config",
"/path/to/.ExifTool_config",
"-P",
"-E",
"-overwrite_original",
...
Is there some way to get the .exiftool_args to start with -config?
I believe I've found an image that freezes the tool every time it is read.
Steps to reproduce:
multi_exiftool_reader = MultiExiftool::Reader.new
multi_exiftool_reader.filenames = [Rails.root.join('a.jpg')]
multi_exiftool_reader.read
I inspected the image with exiftool and I imagine the cause is the huge field "Mask Group Based Corr Mask Masks Dabs".
I've never seen anything like this before, so any ideas how to avoid a freeze are welcomed.
I'm currently tracking an issue with subseconds which looks like it was introduced in 0.6.0.
I'm seeing that when I call
image_exif.SubSecDateTimeOriginal
0.5.0 and below produce the result:
2012:07:13 19:36:01.32
0.6.0 and above produces:
2012-07-13 19:36:01 +0100
Calling subsec on the times from 0.6.0 and above results in 0.
This seems to be the case for all the files I've tested with.
I've attached a sample image:
This is the test code to reproduce:
#!/usr/bin/ruby
gem 'multi_exiftool', '0.9.0'
require 'multi_exiftool'
multi_exiftool_reader = MultiExiftool::Reader.new
multi_exiftool_reader.filenames = Dir['*.jpg']
multi_exiftool_reader_results = multi_exiftool_reader.read
image_exif = multi_exiftool_reader_results.first
puts image_exif.SubSecDateTimeOriginali'm getting ArgumentError: argument out of range when trying to process mp3 file.
I've found out it is caused by invalid date in datetimeoriginal tag - 2022:25:01 16:25 (day and month are switched)
imho this should be escaped to skip the tag or raise some custom error, because ArgumentError is confusing for the user
Hi - Just looking at batching changes to a large number of files using this - it doesn't look like a batch of files can receive different values per file.
Would it be difficult to modify values_args to take an array of valid values in the same order as the filenames array and have the values zip together as the command is built?
Apologies for not putting in a PR - my ruby is rusty rn
Cheers

Hello!
It is designed for dealing with multiple files at once by creating commands to call exiftool with various arguments, call it and parsing the results.
Here is nothing about thread safe. The question is: can I process N files in parallel mode with this gem in the Sidekiq/Xxx with concurrency > 1?
Thanks,
Aleksei.
The use of keyword arguments in delete_values is currently preventing use with ruby 1.9. Are you open to a PR to resolve this?
If i give MultiExiftool a path with spaces, it will break them up into multiple paths:
require 'multi_exiftool'
# => true
reader = MultiExiftool::Reader.new
# => #<MultiExiftool::Reader:0x3a16b68 @exiftool_command="exiftool", @options={}, @filenames=[], @option_mapping={:numerical=>:n, :group=>:g}>
reader.tags = ['-subject']
# => ["-subject"]
reader.exiftool_command = File.join(Dir.pwd, 'exiftool')
# => "C:/tmp/exiftool"
reader.filenames = ['C:/tmp/2009-03-07 Test Path/IMG_4224.JPG']
# => ['C:/tmp/2009-03-07 Test Path/IMG_4224.JPG']
values = reader.read
# => []
reader.errors
# => ["File not found: C:/tmp/2009-03-07/", "File not found: Test/", "File not found: Path/IMG_4224.JPG"]
