Title: [x] [1246] AIMP picks incorrect album title for certain Ogg Vorbis files
Post by: Drag0nFly on March 19, 2023, 07:35:27
Hi Artem and others-

First of all thanks for a fantastic player; I'm using it daily.

I have however come across an extremely weird bug (or behavior, if you will) in the most recent AIMP version on Android (v3.30.1246 (01-Feb-2023) relating to how AIMP displays title and track information for one-track ogg files (btw. most other files of the same one-track ogg type do display correctly, converted the same way from .flac with FFmpeg)

Since I have spent a number of hours trying to "fix" metadata for the problematic ogg file which does not display correctly (AIMP is using *the first song track title* as the album/top-level title - instead of the *main TITLE or ALBUM tags* in the CUESHEET - or the first TITLE occurence in the CUESHEET), I thought it best to send a report here. (I cannot see what is wrong, and it could be something obvious if another person takes a look at it)

I am including mediainfo output for the file below, and a similar file which displays correctly. I have also re-tagged the file several times, in order to add an ALBUM and a TITLE ("track name" the same as the album title). Before doing so, it was similar to the metadata for the ogg file at the bottom (which works). It should not be a UTF-8 issue either, as the cuesheet in question does not have any encoding requiring this (i.e, dos2unix or :set fileencoding=utf8 in vi leaves it as ASCII)

When scraping this file, AIMP reports the album (i.e, top level, before the individual tracks) as "The Man Machine [Warszawa Sala Kongresowa - 27-May-2004]", instead of the album/main title ("Minimum-Maximum").

Since I also thought it might be related to the square brackets used, these were also removed/changed to "(" - and the error followed (album was now "The Man Machine (Warszawa Sala Kongresowa - 27-May-2004)" etc.

Mediainfo output for the file in question:

Mediainfo for a file which displays ok (using the TITLE in the CUESHEET block - this is how the file above was formatted before trying to fix, i.e, no main TITLE or ALBUM tracks, just those in the CUESHEET block):

I would be very thankful for any insights on what is going on here, so that either AIMP can handle this type of file, or I can modify the metadata accordingly if there is something wrong I am not seeing.

Reporting it initially as a bug, as I cannot see any issues with the file, and since the metadata displays ok in other players such as DeadBeef and VOX (I can obviously provide the file itself somewhere so that this can be tested directly)

Thanks.

Your CUE file is not correct:

Code: [Select]
FILE "Kraftwerk - Minimum-Maximum [24bit-96kHz SACD].flac"

must be:

Code: [Select]
FILE "Kraftwerk - Minimum-Maximum [24bit-96kHz SACD].flac" FLAC

Player expects file format token, but got the TRACK token and skip that, so what why it takes title from first track as album

Ah - I had a feeling it must be something trivial, which affects the way AIMP parses the cuesheet & tag information.

I will test this asap and report back!

Yep - it now displays correctly after adding WAVE after "Filename.flac" 8) (I use WAVE as abcde picks this by default when ripping CDs, doesn't seem to have a functional impact on this or other players)

Spasibo! - and for the quick response!

I noticed a separate issue with the album art disappearing in the lock-screen on Android though (re-appears when selecting 'Home' in AIMP and locking the phone again - but it gets reset once the next track starts playing. Not sure if this is known, but I can open a separate case for it). Might only affect one-track (ogg) files.

Thanks again.

Anyway, I've improved my code. Now app will handle this case correctly.

Excellent. AIMP getting even better. :)

(I'll probably embed album covers for the other issue, which I suspect is because the cover-art is downloaded again for each track for single-file albums (as the cover would be on each file for individual tracks... But this is just a guess)
