I already have a gemspec file, but gem screws up bin/chardet by
plastering it with #!/usr/bin/ruby boilerplate (it's a python file).

And I don't know how to turn it off.

Argh, amateurish mistake on my part, thanks for catching that. Fixed.
If in a bit over-engineered way (creating a safely named link to the file.)
Probably impossible to safely pass a filename like "-f -i -l -e -z"
to a shell command that doesn't support "--" in any other way, though.

Right you are. Fixed. No idea what was causing it. Moved to
using id3lib for the tags (it extracts embedded album art as well!) and
mplayer for the rest of the metadata.

Here we go, 0.5:

tarball: http://dark.fhtr.org/repo.../metadata-...
git: http://dark.fhtr.org/repo...

Description
-----------

This package `Metadata' comes with a library called `metadata' and
a small program called `mdh'.

The library probes files for their metadata (e.g. jpeg dimensions
and camera make, mp3 artist, pdf word count) and returns the metadata
as a Hash.

Mdh can print out file metadata as YAML and package the metadata
with the file.

This package has many dependencies since there is no single universal
metadata header format that all files use. Blame resource forks, filename
extensions, bags of bytes and mimetypes.

Usage
-----

# print out metadata header
mdh -p myfile.jpg

# create myfile.jpg.mdh, which consists of metadata header + myfile.jpg
mdh myfile.jpg

# print out metadata header from mdh file
mdh -e -p myfile.jpg.mdh

# strip out metadata header from mdh file and save it to myfile.jpg
mdh -e myfile.jpg.mdh

# print out list of flags
mdh -h

irb> Metadata.extract('myfile.jpg')
irb> Metadata.extract_text('myfile.jpg')
irb> Pathname.new("myfile.jpg").metadata

List of supported formats
-------------------------

Audio:
Whatever you manage to make mplayer play.
Plus FLAC, m4a and wma handled specially.
Successfully tested with:
mp3, flac, ogg, wav
Should also work:
wma, m4a

Video:
Whatever you manage to make mplayer play.
Successfully tested with:
wmv, mov, divx, xvid, flv, ogm, mpg

Images:
Should handle pretty much anything (apart from XCF and ORF.)
Successfully tested with:
jpeg, png, gif, nef, dng, crw, pef, psd

Documents:
Successfully tested with:
pdf, ppt, odp, sxi, ps, ps.gz, html, txt
Should work:
- OpenOffice docs work to some degree (personally, I'm using unoconv to
convert OO docs to temp PDFs for the text & dimensions extraction, so
those bits of data are missing.)
- MS Office docs to some degree (ppt at least, doc and xls should work too,
dimensions missing due to the above temp PDF -thing.)

Others:
Whatever extract spits out on the five or six bits of metadata I'm using
from it. Archive contents at least.

Requirements
------------

* Ruby 1.8

* Tons of metadata extraction programs and libs,
list of gems:
flacinfo-rb
wmainfo-rb
MP4info
id3lib-ruby
list of debian packages:
dcraw
libimlib2-ruby
extract
libimage-exiftool-perl
poppler-utils
mplayer
html2text
imagemagick
unhtml
pstotext
antiword
catdoc
shared-mime-info

* You do want to install the latest versions of dcraw and
shared-mime-info to be able to handle camera raw images.
http://cybercom.net/~dcof...
http://freedesktop.org/wiki/Software/shared...

* Python + chardet library
http://chardet.feedp...

Install
-------

De-compress archive and enter its top directory.
Then type:

($ su)
# ruby setup.rb

These simple step installs this program under the default
location of Ruby libraries. You can also install files into
your favorite directory by supplying setup.rb some options.
Try "ruby setup.rb --help".

Another bug, here we go:

undefined method `audio_x_vorbis_ogg' for Metadata:Module
undefined method `audio_x_vorbis_ogg' for Metadata:Module
/usr/lib/ruby/site_ruby/1.8/metadata/extract.rb:365:in `video_x_theora_ogg'
/usr/lib/ruby/site_ruby/1.8/metadata/extract.rb:142:in `__send__'
/usr/lib/ruby/site_ruby/1.8/metadata/extract.rb:142:in `extract'

That code that seems to be failing is:

def video_x_theora_ogg(filename, charset)
h = video(filename, charset)
wma = audio_x_vorbis_ogg(filename, charset)
%w(
Artist Title Album Genre ReleaseDate TrackNo VariableBitrate
).each{|t|
h['Video.'+t] = wma['Audio.'+t]
}
h
end

This makes sense, as audio_x_vorbis_ogg() doesn't exist anywhere else. :D

Ooh, here's another: :)

/usr/lib/ruby/site_ruby/1.8/metadata/extract.rb:735:in `unlink': No such file
or directory - _tmp_metadata_temp_22720__604265598_1189946590.27022

Not sure what that is, and frankly atm my brain is a bit too weak to think
about it. But you should be fresh and able to solve that.

Apparently temporary hardlinks weren't such a hot idea after all. Nuts.

Ok, now escaping filename by default, only trying to "ln rescue cp" for
filenames starting with a dash. Running it against my downloads-dir
presently, been working ok thus far. YMMV of course :)

The title tag isn't being parsed out of oggs:

$ mdh -p music/korn_-_clown.ogg
Video.TrackNo: 16
Video.Artist: Korn
Video.Genre: Hard Rock
Video.Album: Greatest Hits Vol. 1

vs mplayer:

Ogg file format detected.
Clip info:
Genre: Hard Rock
Name: Clown
Artist: Korn

Ah, it uses Name instead of Title. Thanks!
Added it and made 0.8.

http://dark.fhtr.org/repos/metadata/metadata-...

Now I wonder what other synonyms mplayer uses...
I'd really appreciate it if you could run the following over
your media library and tell what field names it spews out:

find $MEDIA_LIBRARY_DIR -type f | mplayer -identify -ao null -vo null -frames 0 -playlist - | grep ID_CLIP_INFO_NAME | sed 's/^.*=//' | sort | uniq

(replace $MEDIA_LIBRARY_DIR with the directory name)

Thanks again,

I'd love to run that but mplayer dies rather early on on some of my files.
Also, seems like we have another bug (not sure what kind of file it's on,
sorry):

undefined method `empty?' for 40:Fixnum
undefined method `empty?' for 40:Fixnum
/usr/lib/ruby/site_ruby/1.8/metadata/extract.rb:765:in `enc_utf8'
/usr/lib/ruby/site_ruby/1.8/metadata/extract.rb:352:in `video'
/usr/lib/ruby/site_ruby/1.8/metadata/extract.rb:142:in `__send__'
/usr/lib/ruby/site_ruby/1.8/metadata/extract.rb:142:in `extract'

I'd guess one of the libraries you're using for parsing is giving back 40
as a genre or track number (a bit high, but might be tagged wrong) and it
needs to be converted to a string before you can use it.

Thanks!

Hmm, here's a ruby version that should work through those:

media_dir = "music"
seen_names = {}
mpc = "mplayer -identify -ao null -vo null -frames 0 -playlist - 2>/dev/null"
Dir["#{media_dir}/**/*"].each{|fn|
if File.file?(fn)
IO.popen(mpc, "r+"){|mp|
begin
mp.puts fn
mp.close_write
tags = mp.read.strip.split("\n").grep(/^ID_CLIP_INFO_NAME/)
names = tags.map{|t| t.split("=", 2)[1] }
names.each{|n|
seen_names[n] ||= (puts n; true)
}
rescue
end
}
end
}
