Music Duplicates - length field isn't populated if length is not selected as a matching option

[kaysond]

Running 4.1.0 on Windows Server 2k19. If I don't select length as a matching option, the length isn't shown in the results. It would be nice to have that as a means of comparison

[qarmin]

If length or year is not visible, that means that music file doesn't have such info in their tags.

If length or year is not visible, that means that music file doesn't have such info in their tags.

Which tags/frames are you looking for? Here is the media info dump for the files in the bottom of that screenshot. It has both year and duration.

[qarmin]

Can you post example audio file?

I think that one of three things could happen:

• file tags are not recognized by lofty library that Czkawka use
• length tag is different thing that duration
• app read only first/primary tag, but info is written in second, third etc.

[kaysond]

So I ran through all 4000 dupes last night, and none of them had year/length.
Looks like maybe you fixed this, but here's an example file in case: https://mega.nz/file/9koTiKbK#D1SgN2nHD_3tftB5pzJ7Sx236xouqJIN4ADS8-QJ3WM

I can test it next release

[qarmin]

Nightly builds can be downloaded from Actions tab - https://github.com/qarmin/czkawka/actions

Example build with fix - https://github.com/qarmin/czkawka/suites/6300147458/artifacts/225841924

[kaysond]

Doesn't seem to be fixed. I tried the latest build:

I checked the commit, and I wonder if it's an issue with the tag names?

[qarmin]

Didn't checked tags in app yet on provided file, but looks that it doesn't have length inside its tags.
This is what I got when reading tags from ffprobe

[mp3 @ 0x56500da66ec0] Estimating duration from bitrate, this may be inaccurate

[kaysond]

Interesting. I used mediainfo which didn't complain about it, but I see the same thing with ffprobe. I tried some other files where ffprobe does not give that message, and it still doesn't show any year/length at all in czkawka.

Here's an example output:

The problem was was caused by reading only tags of music file and sometimes not reading tags due missing primary tag.
Strawberry, FFprobe and similar apps use audio properties to calculate length of music file and Czkawka will do exactly same after updating lofty library - #705
