GNOME Bugzilla – Bug 454147
album art as thumbnail previews from embedded mp3/ID3
Last modified: 2010-07-03 05:58:48 UTC
MP3's (and other formats that use ID3) can contain album art embedded in the ID3 tags, this could be used to generate thumbnails for the files. Also it could check for cover.jpg, folder.jpg, _folder.jpg and Banshee's downloaded covers.
Thanks for the report. Your suggestions are also explained in the older bug 84297. Closing as a duplicate. Thanks for the bug report. This particular bug has already been reported into our bug tracking system, but please feel free to report any further bugs you find. *** This bug has been marked as a duplicate of 84927 ***
The duplicate seems different to me, this one is specifically about using the art inside the mp3 files themselfs (from the ID3 tag which has the ability to store .jpgs inside of .mp3s) for the icons of mp3 files themselfs like how images files get thumbnails of their content. The duplicate is about folders not files, specifically using folder.jpg files for folders or other files or getting the image file from somewhere else. Even if the folder one is done, it would be nice to have this one for the files inside of the folder.
In that case, it's far beyond Nautilus' ability. We only thumbnail files which we have a set thumbnailer for, or image files which Nautilus thumbnails internally. You would need to write a thumbnailer capable of reading said embedded images, extracting them, and storing them according to the Thumbnailing specification. Then assign the thumbnailer to the audio file's content-type. The latter part of this can be read about here: http://library.gnome.org/devel/integration-guide/stable/thumbnailer.html.en The rest of the bug is covered by the duplicate bug (being able to use e.g. folder.jpg to represent the folder automatically).
Noticing this one didn't get closed.
