ID3 tags act weird

[DeFlaaj]

Hello,

Experiencing strange behavior when I get ID3 tags from certain files. (using ID3_v3.4.au3)
It works fine with most of the files but in certain repeatable cases, it loads only the artist tag... But not really:

In MsgBox, it only shows artist tag and no title tag. Not even the " - " text (weird!) nor total time
In Playlist, it does the same thing.
In Label, it shows both artist and title tag and current/total time correctly.
In ConsoleWrite, all values are also shown correctly. Although, in 'Solid Earth' case and similar, it writes the tags in the same row:

$sTrackArtist: The Future Sound Of London$sTrackTitle: Solid Earth$sTrackArtist: Ty Segall
$sTrackTitle: Imaginary Person

Cannot wrap my head around it...

Thanks for your help

I'd like to take a look, but please provide a running reproducer with includes and a sample mp3 you have problems with.

[DeFlaaj]

Indeed. It also uses ffmpeg.exe but it's not relevant for this issue.

The issue happens with basically all files from bandcamp.

Thank you!

It looks like you have a null char at the end of the string. You can do something like this to delete all trailing null chars:

$sTrackArtist = BinaryToString(StringRegExpReplace(StringToBinary($sTrackArtist), '(00)+$', ''))
MsgBox(0, "id3", $sTrackArtist & " - " & $sTrackTitle)

That's right  Didn't know this exists. Thank you so much!
