View Full Version : Media not found

I have been ripping my CDs and building up my library for a while now. However, a substantial number of CDs (media files) are not being found and added to the Media Library on scanning or rescanning. From what I've read so far, I know special characters in the file name can cause problems, but I don't think I have any media files with special characters in them.

Secondly, artists are sometimes duplicated. I've been told the file name structure contains tags which can cause this to happen.

Examples of unexpected duplicate artists found in my library.

Cult With No Name
Cult with No Name

Jamaica Jazz
Jamaica Jazz all Stars

Joni Mitchell
joni mitchell

etc,...

All my files are stored using on disk using the following file naming convention.

<genre>/<artist>/<album>/<nn trackname>

I don't know how to fix this and there's a lot of duplications.

Hi,

lms (its database) is case sensitive.


Cult With No Name
Cult with No Name
Cult with no Name

are 3 separate Artists or Albums.
You have to use a mp3/flac/whatever tagger that is supported by your unknown Operating System.


Files - that not found from the scan processs are mostly listed in the scanner/Server logfile. Or these logfiles cant give you a hint.

First things first: check your scanner.log file. Did the scanner crash
at some point? You can upload it here for further analysis.

> Cult With No Name
> Cult with No Name
>
> Jamaica Jazz
> Jamaica Jazz all Stars
>
> Joni Mitchell
> joni mitchell

These are not duplicates. It's different spellings of what you think was
the same thing. But different spelling will result in different results.
Fix the metadata in those tracks, and you'll get rid of the
"duplicates". Use something like mp3tag for mass-tagging if there are a
lots of changes to do.

Thanks for the replies. My LMS is running on Linux.

Ye.s I was aware that letter case makes a difference. However, what I wasn't aware of is that LMS catalogues my collection by file tags and not bythe file naming structure I'm using or perhaps it using a mixture of both?, I'm still not sure.

The mp3tag tool is great. I've already sorted out "Cult With No Name". I still don't understand is how the media files are being tagged inconsistently. I assume it must be the ripping software that is tagging the media files. Does the ripper tag with what it finds online or what it reads from the CD? Using the Cult With No Name example, I have two albums, firstly 'Another Landing' and secondly 'Paper Wraps Rocks'. Am I getting my duplicate because one album has "Cult With No Name" as the artist and the other has "Cult with No Name"?

I'll look at the scanning log again and post details if I don't see what the problem is.

Your example of the 2 albums is exactly what will give you multiple artists because one has with and the other With in the artist field.

Another example might be Hall And Oates vs Hall & Oates.

When adding new music by artists I already have I go back to check how I tagged earlier recordings to avoid this issue.

The point I'm trying to make is I AM NOT TAGGING THE MEDIA FILES. I can only conclude that the ripping software is doing it. However, it's clear that it's not doing it consistently. I'm trying to find out why this is so.

Hi,

Here is some "user" that wrote a line like:

Sampler sucks..
This "User" is also "our" Main Distributor ;)

Whenever i add a new Sampler to my collection i always hear my brain listen to that sentence :mad::rolleyes::D - cause i know what Michael is meaning with it.

If you already familar with mp3 tag - use it.
If your Files are already sorted in "artist/albums" Folders - just grap one artistfolder after another and mass change the Artistname.
Beware of old (id3v1) and newer (id3v.2.x) tags - they are separate tags even when Artist on v2 says "Whatever" idv1 could also say "whatEver"!

So my behaviour is get rid of the id3v1 Tags.


If you familar with linux - try eyeD3 a commandline Tagger or puddletag (a mp3tag clone written by a guy who is also a lms User).

Since lms didnt drop renamed Artists - you have to clear & rescan instead of just rescan (the old Artist would be there - but without Tracks)

BIG Mistake!
There are "good" reasons eg.
De la Soul (https://www.discogs.com/de/artist/4091-De-La-Soul)
and bad reasons (misspelling from someone who exports his typofailure to CDDB) that a Artist has different Names.

CDs don't contain tagging data. (metadata)
Your ripping software gets it's metadata from an online database.
The database is probably populated from tags typed by your average Joe or Joes, Joe & Joe have different interpretations of the metadata they use.
After ripping, all my CD's are subsequently opened in mp3tag, and tagged how I want them, not how Joe or Joe has specified.

Tag your music files using mp3tag as you wish to see them, then clear your library and rescan everything.

In case of no tagging at all LMS tries its best to "guess" album and artist from the file structure , but its a algorithm . Tags are much better you eventually get what you want .
And all the album and artist and genre menus and more starts to work properly , for example search works much better .

Otherwise you are forced to use the "music folder " browse option to find your music , it is just that it browses the folders ,but this is slow .

It also uses cue files and eventually m3u files aka playlists .


In LMS settings/advanced/formatting you have "Guess Tags Formats" here you can influence the guesswork a bit

Thanks again, I now understand what's been causing the problems. My catalogue is already much improved.

I'm now also confident that the scanning process had been missing CDs due to bad tagging, such as Unknown Artist, Unknown Album, etc.

I tend to use XLD to rip my CDs. Is there a ripper that can adds tags that I want during the rip with minimal typing? Perhaps XLD is capable of doing this, but I'm just not using it properly? I know there's a ripper for Windows (I can't remember the name) that a lot of folks like, but I found it rather complicated. Perhaps it's worth making the effort to learn how to use all of its functionality or use another ripper?

Two of the more high-sophisticated rippers are dBpoweramp and EAC (exact audio copy). They verify what they rip against other users' rips.

BTW, you don't need to avoid special characters in file names or in the tags, LMS can handle them properly (if your OS and/or tagger does).

I would still be careful using them, as eg. when naming tracks on
Windows, then transferring to your Linux box of whatever kind where you
run LMS could still cause problems. And this is a quite popular use case.

In the tags i would use unrestricted amounts of odd characters , but not in the file names .

Passning the files over different OS and different disc format system over the years can do stuff . And different locale settings in the machines ?

Another less than obvious quirk , different OS have different forbidden characters that's well known ,control chars like slashes and back slashes etc .different disc formats like NTSF ext3 FAT etc also has forbidden chars . What's less known is that they may not match the OS they are used with . For example NTFS as a disc format allows things that Windows can't do .
So a Linux or Mac computer can write a perfectly valid file to a NTFS disc that Windows can't read .

I once had files that looked okay in Natilius Ubuntus (Linux) "explorer" but not when viewed in a shell ?

Tags an file names do not need to match, in classical music the title can be rather long on both album and tracks . If you have an OS that restricts you to 256 character long file paths that's also a problem .

Some are in the habbit of having both artist and album name included in the the track name . if you move to a deeper file structure you may hit this limit .

And use a file format that have good tag support FLAC or ALAC for example but flac is more widely supported and has good hardware support in squeezeboxes

Yes, it was EAD I was referring too, thanks. I'll give it another try.

I agree that mixed environments could cause problems, so you have to check. But I'm ripping on Linux and copying the files over to Windows where I modify them and where LMS is running and I don't have issues with all kinds of really strange looking characters in both file names and tags, for example from Nordic countries like Sweden ;)

try to copy a file like
artist - album - track - title (12"):p
There are all kinds of special chars, that gets you in trouble...
