[ubuntu] [SOLVED] Adding mp3 info columns (e.g. bitrate, etc.) to nautilus list view

[geb666]

Here's a solution I found to a problem some people posted about in these threads, however, I can't seem to reply to those posts so I'm creating this new thread. First, you need to install python-nautilus and python-mutagen. You might have to add the python-nautilus library path to the PYTHONPATH variable. Then create a directory called python-extensions in ~/.nautilus. Put the script below in that directory in a file called bsc.py or you can download the attachment. Remember that python uses tabs for defining scope, so if you copy and paste the script below then you'll have to replace the spaces with tabs. Finally, restart nautilus. That should do it.

P.S. I took the code from this post and modified it.

import os
import urllib
import nautilus
from mutagen.easyid3 import EasyID3
from mutagen.mp3 import MPEGInfo

class ColumnExtension(nautilus.ColumnProvider, nautilus.InfoProvider):
        def __init__(self):
                pass

        def get_columns(self):
                return (nautilus.Column("NautilusPython::title_column",
                                "title",
                                "Title",
                                "Song title"),
                nautilus.Column("NautilusPython::album_column",
                                "album",
                                "Album",
                                "Album"),
                nautilus.Column("NautilusPython::artist_column",
                                "artist",
                                "Artist",
                                "Artist"),
                nautilus.Column("NautilusPython::bitrate_column",
                                "bitrate",
                                "Bitrate",
                                "Bitrate"),)

        def update_file_info(self, file):
                if file.get_uri_scheme() != 'file':
                        return
                if file.is_mime_type('audio/mpeg'):
                        filename = urllib.unquote(file.get_uri()[7:])
                        audio = EasyID3(filename)

                if (os.path.isfile (filename)):
                        mpfile = open (filename)
                        mpinfo = MPEGInfo (mpfile)
                        br = str(mpinfo.bitrate/1000) + " Kbps"
                else:
                        br = ""

                file.add_string_attribute('title', audio["title"][0])
                file.add_string_attribute('album', audio["album"][0])
                file.add_string_attribute('artist', audio["artist"][0])
                file.add_string_attribute('bitrate', br)
                self.get_columns()

It could be that the original thread is in the archive - perhaps you could link to it so others can see.

Could you also mark the thread as solved - it appeared that the thread was an unanswered support request, thanks.

Geb - worked like a charm. This was driving me crazy. Thanks so much for posting it. The only thing I noticed is it doesn't seem to work on network shared folders.

I love this solution! Thanks guys! It was, however, missing one critical feature for me. It was missing a way to show the ID3 date tag. I've updated the script a bit, and here is my revision:

It would be great if this script were also updated with support for displaying JPEG EXIF shooting data. I, unfortunately, am not a Python wizard.

UPDATE: I have tried my best and updated this script with EXIF shooting information! It seems to work okay!

UPDATE #2: It now works better! Sometimes mp3 info was there but not getting filled in, also mp3 length support is now added.

UPDATE #3: Thanks to SabreWolfy for finding another unhandled exception!

UPDATE #4: Thanks to gueba for discovering this script wasn't properly closing file handles until it terminates

UPDATE #5: Thanks to Pitxyoki for discovering this script wasn't properly closing file handles if there's an exception

UPDATE #6 (9/17/2009): Thanks to enbeto for finding a way to read video information!

UPDATE #7 (9/23/2009): This is now in a Debian package for easy installation. I have kept the bsc-v2.py source attached in case anyone wants to review it. This is my first attempt at a Debian package, so please be nice in criticisms!

UPDATE #8 (9/27/2009): Updated nautilus-columns to support ID3 tags in FLAC, thanks l-x-l!

UPDATE #9 (10/5/2009): MKV support added. Version bump to 0.01.

UPDATE #10 (10/6/2009): postinit script automatically restarts Nautilus so options can be seen without logging in and logging out. Thanks thegutterpoet!

UPDATE #10 (10/26/2009): album/date added for FLAC/video. Thanks eldon.t!

Can someone help me please?

ID3 tag organization columns are necessary.
I have followed this tutorial and used both provided files, the original and the edited one, neither work for me. I created the directory under /.nautilus, places the file there, and restarted nautilus. nothing happens.
One thing I do not understand is the lin in the instructions stating to change a path in capital letters?

please help the noob!

One important detail, did you put it under /.nautilus or ~/.nautilus, they are two very different places on your file system.

[jmdsdf]

mrucci, ensure all the dependencies are present, ensure that the script goes into ~/.nautilus/python-extensions/ or /usr/lib/nautilus/extensions-2.0/python/. Make sure you restart Nautilus (I just run "killall nautilus" from the terminal, or run dialog, i.e. Alt-F2). Then open Nautilus, and under Edit | Preferences | List Columns, you should see the extra columns. I hope this helps!

Btw, I updated the script with some more field I hope these will help everyone with managing photos with meta data. One shortcoming I have noticed is that Nautilus, unlike Windows Explorer, does not remember which folders should have which column headers. Oh well. A small annoyance, but not a critical one.

[mrucci]

Aahh! Thank you so much! It works now! one thing I passed was that there are instructions in the py file. need to read more.

But yes, I think my directory orientation was off.

Thanks for the help everyone, working great now!

[SpetsnazC4]

Thanks for this great post! It's just what I need. Is there a way to view the mp3 track length/duration in a column?
