Recordings listed, but missing after database backup/restore

[qymm]

Hi there, was looking for some help.

I just installed BirdNET-Pi on a new Raspberry Pi 4B, upgrading from a Raspberry Pi 3B. New SD card too.

Fresh install, but I transferred the birds.db, the birdnet.conf, and the BirdSongs\Extracted\By_Date\ folders. I'm running into an issue where looking at Recordings > By Date > 2024-02-02, for instance, American Crow is listed, but clicking on it shows No recordings were found. The recordings are physically present in the directory, both .mp3 and .png, but are not listed in the webUI. What could I be missing?

wild shot: that old classic, permissions maybe? or ownership?

[qymm]

That's been done already, it did not have an effect.

I also just ran an ls -g on a set of soundfiles that are appearing, and a set of soundfiles that are not appearing, and both appear to have the same permissions/ownership:

Not appearing:
-rw-r--r-- 1 $USER 96384 Feb 2 15:00 American_Crow-92-2024-02-02-birdnet-14_00_11.mp3
Appearing:
-rw-r--r-- 1 $USER 96384 Jun 20 05:58 American_Crow-55-2024-06-20-birdnet-05:58:16.mp3

Oh my word, I just noticed the discrepancy. The filename was sanitized at some point, the colons were removed from the timestamp.

hmm, I did not see that one coming 😄

I am running a regex rename in order to rename each of the files in the directory that match with the sanitized file format back to include colons in the timestamp.

This has solved the issue, at least for one date so far. Thanks for rubber ducking for me.

find . -type f \( -name "*-*-*-birdnet-*_*.mp3" -o -name "*-*-*-birdnet-*_*.mp3.png" \) -exec rename 's/(.*-birdnet-\d{2})_(\d{2})_(\d{2})(\.mp3(?:\.png)?)$/$1:$2:$3$4/' {} +
