Randomly missing playlists in Rekordbox formated drives

[emmetiray]

When i go to my Rekordbox usb devices in Mixxx there are always some playlists missing.

Don't know if this is a known issue.

Cheers Jakob

Thanks for reporting, but some information is missing in this bug report. For example, what OS and what Mixxx version do you use? (GitHub should ask for this information when you choose "Bug Report" when opening a new issue).

In this case, it would also be helpful if you could attach a mixxx.log logfile. Ideally, we'd also appreciate if you could attach the PDB file from the USB drive in case it's some issue with our parser.

thx for the infos. and great work by the way. at the moment i'm using mixxx under win10 but my plan is to install
it on the steam deck. so it will be steamos/arch linux soon.

pdb.zip
mixxx.log

2.4 windows alpha same problem.

[emmetiray]

its working fine on rekordbox and my xdj700 btw.

[Swiftb0y]

Since this issue occurs with mixxx and Holzhaus/rekordcrate#76 (which are using two different parsers) I assume this is probably an edge case that is not accounted for in the unofficial reverse engineered "reference specification". I'll look into the phenomenon.

[Swiftb0y]

@emmetiray can you elaborate what playlists are missing exactly? The database is too big to find irregularities by hand. I'd need to know what to look for. Can you tell me what info is missing exactly? Is it just the playlist name or also its content? Does it have anymore identifying data (how many tracks did it contain, what tracks for example, etc). Are these playlists missing completely or just empty like in your screenshot?

[Holzhaus]

Maybe this is due to non-ascii chars? For example, is the playlist BEAT PVP - BEAT PVP 1ª EDIÇÃO one of the missing ones?

[emmetiray]

@Swiftb0y @Holzhaus
so in mixxx some playlists are just empty fields and there is nothing in it. there is one really big folder called "oldfolders" with a lot of different playlists inside. mixxx seems to be unable of showing more then 2 correct playlists and 2 unnamed empty fields with nothing in it once they are inside a subfolder. and there are actually two correctly named playlists in the main directory (so not in some sub folder) which in mix are just empty. "mix" and "skeelo". i took some screencaps comparing the playlist structure in mixxx and rekordbox. perhaps that helps? thx.

if you place the screenshots next to each other you see some big differences...

[Holzhaus]

I had another look at this. Is the following list complete?

[emmetiray]

playlist and folders seem to be complete. :)

[Holzhaus]

Ok. that means that rekordcrate can read the whole list properly, so it's probably not some issue where the unofficial docs are wrong. It's either a bug in the generated kaitai code or some issue with our library feature implementation (more likely IMHO).

[Swiftb0y]

Browsing the pdb using the kaitai web ide also makes it look like its complete. So I'd blame the library feature implementation too.

[Holzhaus]

@emmetiray please have a look at: #10955

[Swiftb0y]

I think the original issue should have been addressed by #10955. Lets close this for now. Feel free to reopen if not.
