Special tags not indexed

[bjoernminim]

Hi Simon

I'm new to MinimServer and I am very happy in combination with BubbleUPnP. But there is some strange problem. In http://forum1613.minimserver.com/showthread.php?tid=194 you write, that MinimServer can handle every tag name, but this is not working for me. It seems, that MinimServer indexes only the tags, which are listed in http://minimserver.com/ug-library.html#Tag mappings. All the other tags are not indexed.

For testing purpose I put only two files in the ContentDir, one is tagged in MediaMonkey, the second is tagged in Mp3Tag with Id3v2.4, but I couldn't find any difference concerning the indexing problem. MinimServer is running on Synology NAS in the newest version of DSM and MinimServer.

I've attached several files for you to better understand, what I mean:

1. MP3Tag-Expanded Tags-Screenshot 1     & 2     : In these screenshots you can see, what tags are contained in the two files with the tag names, Mp3Tag uses
2. HEX-Editor-View of Tags 1     & 2     : In these screenshots you can see, what tags are contained in the two files with the tag frame names
3. MinimServer.config
     minimserver.config.txt (Size: 1.28 KB / Downloads: 9) : Here you can see my configuration. You can see, that for testing purpose I took all tag names I found in Mp3Tag an in the HEX-View and used them in the indexTags-Property of MinimServer.
4. allTags.log
     allTags.log.txt (Size: 825 bytes / Downloads: 3) : Here you can see, that only tags from your "Tags mapping"-list are indexed and none of the special ones like Rating or Involvedpeople
   

Do you have some idea, what I'm doing wrong?

Kind regards
Björn

It looks like you have edited the minimserver.config file by hand. This is not recommended or supported and can cause problems. You should use the Properties dialog to modify the indexTags property.

Copying values from a hex dump of an MP3 file into indexTags is not the correct way to set indexTag values.

The menu only shows tag choices for tag names that have multiple values available for the tag name. With a test library containing a single file, many tag names will not be shown as choices because there is only one available value for the tag name.

Please give an example of a tag name that you want to index and is present in your test files and is not showing in the index.

Hi Simon

Thanks for your fast reply!

I didn't edit the minimserver.config-file. You thought so probably because I had to add the txt-File-Ending caused by the limitiation of the forum, which does not allow attachments with the config-ending.

For test purposes I added the hex dump-Names of tags (TIPL as an example) AND the Mp3Tags-Names of tags (INVOLVEDPEOPLE as the corresponding example). If I understand you right, in this example INVOLVEDPEOPLE would be the right tag name for the indexTags-Property?

I knowed this because of other of your replies in the forum. But I had the same problem with 30'000 files as well. For testing purposes I didn't look at the menu in the control point. I used the writeAllTags-Property instead, which produced the allTags.log.txt-File I attached to my initial post. I suppose, that in this file all the indexed values should be written, even when they are same between the two files in my test content directory.

In the following list you'll find all the tag names, which I added to indexTags and got not indexed. In bold font is the name from Mp3Tag and in italic font the corresponding one from HEX. As I wrote above I added both to indexTags:

1. COMMENT SONGS-DB_CUSTOM2 Songs-DB_Custom2
2. Involvedpeople TIPL
3. Rating MM and also Popularimeter POPM
   

If it helps I could also send you the two mp3-Files in a personal message.

Thanks for these clarifications. See my comments inline below.

OK, apologies for the misunderstanding.

TIPL is the name of the ID3v2.4 frame. Frame names are not the same as tag names. Frame names should not be used in the indexTags property and have no effect if they are used. You could include INVOLVEDPEOPLE in indexTags but this will not work with .mp3 files because Mp3tag is mapping this name to the TIPL frame and MinimServer is not reading this frame. If you were doing this with a .flac file, INVOLVEDPEOPLE would be read by MinimServer.

This is the right way to do it. Thanks for clarifying.

MinimServer maps the COMM frame to the COMMENT tag but does not map the content description Songs-DB_Custom2. This is because there is no standard mapping (i.e., a consistent mapping that is widely supported by converter programs and tagging programs) for the content description.

MinimServer doesn't map the TIPL frame. This is because there is no standard mapping for this frame. MinimServer maps INVOLVEDPEOPLE information encoded in a TXXX/INVOLVEDPEOPLE frame but Mp3tag does not support writing this frame.

MinimServer doesn't map the POPM frame. This is because there is no standard mapping for this frame. MinimServer maps RATING information encoded in a TXXX/RATING frame and Mp3tag supports writing this frame.

MinimServer maps any tag name that appears in an ID3v2 TXXX frame. However, not all tagging programs support writing tags in this format, as the example of INVOLVEDPEOPLE shows. A workaround would be to use a different tag name for this information (for example, INVOLVED_PEOPLE) and use the aliasTags property in MinimServer to map INVOLVED_PEOPLE to INVOLVEDPEOPLE.

Hi Simon

Thanks for your clarifications. I did not knew about the TXXX user defined text information frame, thanks for your hint. I read know some texts in http://id3.org/id3v2.3.0 and http://help.mp3tag.de/main_tags.html. So when I'm understanding you correct, I'll have to do the following:

1. The COMMENT SONGS-DB_CUSTOM2-Tags I cannot use. I have to use another Tag to save this information, either a standard one like Mood or a TXXX-custom one.
2. The Involvedpeople I cannot use, because it is a defined id3-tag, which is not mapped to Vorbis by MinimServer. Also here I have to use another standard tag or a TXXX-custom one.
3. For the Rating I can use any TXXX-custom field, for example the TXXX-Rating or exclusively TXXX-Rating? Here I am not 100% sure, if I understood you right.
   

Concerning the TXXX-tags: Have I understood right, that Mp3tag saves every Tag-Name, that is not standard id3 as TXXX? So INVOLVED_PEOPLE would automatically become TXXX-INVOLVED_PEOPLE?

Thank you again for your help. I just donated some bucks for your great work!

Kind regards
Björn

You are correct about COMMENT SONGS-DB_CUSTOM2 and INVOLVEDPEOPLE. For rating, you can use any tag name. The advantage of using RATING is that this already appears in the standard Mp3tag list of extended tags.

You are also correct that Mp3tag uses TXXX to save any tag name that doesn't have a defined ID3 mapping in the Mp3tag program. These mappings are not part of the ID3 standard and might be different in other tagging programs. To confirm what is happening, you can use a hex editor to look in the .mp3 file.

Many thanks for the donation!

Great. Thanks for your answers. So I will try these things in the week-end. Have a nice weekend
