mp3 track reported as corrunpted but playing well

2025-02-12 07:29:59

Hi All, this is a very low priority topic, but I am curious to learn about.
I have 2 mp3 tracks that are reported as corrupted by "Library Scan" function, but in the reality they both play "apparently" perfect.

Anyone has an idea of what it could be?
Is there a solution for sanitising these 2 tracks to avoid the library scan error?

Thanks and regards, Andrea

I'm confused. It's my understanding that library scan errors are fatal errors for files that foobar2000 cannot handle. Are you certain you are testing the right files? Note that the 'Show errors' button on the Media Library preferences page allows you to right click on an entry and open Explorer to the file. You can then easily drag the file to foobar2000 playlist and see if the file indeed works.

Anyway, the file repair question depends entirely on what kind of error we are dealing with. Could be something simple that a remux fixes, could be a wrong extension that a rename fixes, could be a matter of missing decoder, or could be a file that can only be partially salvaged by transcoding to something else. Without data it's impossible to say.

Hi @Case , I confirm the following 2 (only two) mp3 file are reported as corrupted or usupported format, but Integrity Check says all OK, as well as real Play goes fine.
Please, see herein attachments for details. And, if of help, I can provide you also the 2 mp3 files.
Regards, Andrea

PS: In the library error log, obviously, the .ts files are unsupported because are video.

Your screenshot unfortunately doesn't prove you are testing the same files as it doesn't show the paths of the tracks. The mp3 files have " (Cover)" in their names after the feat part, though of course your tag contents can be different.

The "Unsupported format or corrupted file" means that foobar2000 doesn't support the file. If you try to actually play a file that gives this error, you will only get another error saying "Unable to open item for playback (Unsupported format or corrupted file)".

There is of course the possibility that you have replaced the corrupted MP3 files with working copies after the library scan. The error messages don't disappear even if your files get fixed.
Note that if you clear the error log without fixing the files they won't be reported again, unless you remove the path from library, restart the player, and re-add the path to the library.

If I'm wrong I'd very happily take a look at the two MP3s.

ffmpeg -i corrupt.mp3 -c:a copy fixed.mp3

This ffmpeg command does not reencode the audio data, it only remuxes it and while doing so, hopefuly gets rid of the corrupt stuff in the file, which is probably non-audio related.

Hello @Case and @lovecraft , thanks a lot for your kind and prompt support. The problem was on my HDD. Now all fixed and no more error reported by library scan.
Kind regards, Andrea
