I suspect the reason you're seeing this so frequently is because you're using the previewgenerator app.

As to the underlying cause, that's a different matter. I assume you have some MP3 files among your Nextcloud data files?

The spot where this is happening (in a 3rd party library) suggests to me that the codec or layer versions (one or both) are coming up empty on at least one of your MP3 files.

You may be able to figure out what file it is by running previewgenerator manually from the command line with verbosity on (i.e. append -vvv to the command line)

https://github.com/nextcloud/previewgenerator?tab=readme-ov-file#commands

Lastly, there may be opportunity to explore having the mp3info library handle this unexpected situation a bit differently. Currently it looks like there is no fallback default if none of those headers match:

Upstream PR created to generate an informative exception when this happens: wapmorgan/Mp3Info#36

janusn commented 6 months ago

Thanks for your reply.

I suspect the reason you're seeing this so frequently is because you're using the previewgenerator app.

Yes, you are right. I have a crontab running $ occ preview:generate-all -vvv every hour.

As to the underlying cause, that's a different matter. I assume you have some MP3 files among your Nextcloud data files?

Indeed, I see mp3 files in the logs generated from the previewgenerator.

The spot where this is happening (in a 3rd party library) suggests to me that the codec or layer versions (one or both) are coming up empty on at least one of your MP3 files.

You may be able to figure out what file it is by running previewgenerator manually from the command line with verbosity on (i.e. append -vvv to the command line)

Here is a snip of the file output with -vvv flag:

There is no error in the log.

Excluding mp3 files from previewgenerator seems unrealistic. And it will still generate errors while a user browse the folder with mp3 in it.

joshtrichards commented 6 months ago

Yes, you are right. I have a crontab running $ occ preview:generate-all -vvv every hour.

Not the cause of your situation, but generate-all is generally only ran once:

janusn commented 6 months ago

@joshtrichards

The reason I run occ preview:generate-all on cronjob is for files on external storage.

occ preview:pre-generate does not work on external storage.

Good find! Thanks for the info.

I think I have reported this years ago but no fixing was planned at that time.

janusn commented 6 months ago

@joshtrichards After consulting the document, I realized it does not apply to external storage. Hence occ preview:pre-generate still do not work on external storage. 😞

janusn commented 5 months ago

I have edited the config.php to exclude MP3 files from preview generation. It helps to cut down the errors generated. Now only 63 errors since Mar 30.

Albirew commented 4 months ago

just tried to manually patch @joshtrichards changes from wapmorgan/Mp3Info#36 and i can confirm the errors flood have stopped without additional issue when reading metadata or listening mp3.

Yes, after edition, it is indeed solved in my instance of NC29.0.1 (I would still have to patch it again after an update, tho)

prairietree commented 4 months ago

I just updated my docker Nextcloud to version "Nextcloud Hub 8 (29.0.1)" and started seeing these errors. I did not see these before updating.

Aureliolo commented 4 months ago

Same here. Got thousands of those same errors every second. Just upgraded to 29.0.1 Didn't have an issue on 28.

Don't have preview generator active either.

Not quite sure what app is causing this as im using a very slimmed down nextcloud for just filestorage basically.

mayonezo commented 3 months ago

I got these with 29.0.2 now.

XueSheng-GIT commented 3 months ago

Never noticed those errors. But after NC 29.0.2 update log is full of this error.

Same here, errors appear after 29.0.2 upgrade. I don't use the previewgenerator app.

Same here, even though I don't knowingly use the previewgenerator app.

As I don't know how do disable it inside the Music app, I disabled the app...

manu-p commented 3 months ago

I think you can disable mp3 preview by adding an 'enabledPreviewProviders' section in config.php without the ''OC\Preview\MP3',' line as explained here.

Albirew commented 3 months ago

in the meantime, since i don't want to whitelist what preview i want to keep or not, i made a patch file that i reapply after every updates you can save code below into a text file called mp3info.patch in your user folder and apply patch with the command sudo patch /path/to/nextcloud/3rdparty/wapmorgan/mp3info/src/Mp3Info.php < ~/mp3info.patch

joshtrichards commented 3 months ago

The patch at https://github.com/wapmorgan/Mp3Info/pull/36 (slightly updated today) can be applied if you can't wait for a maintenance release. The file to update/replace in your Nextcloud installation folder is at 3rdparty/wapmorgan/mp3info/src/Mp3Info.php

We'll patch the version we distribute w/ Server in the next maintenance release regardless of the status of the upstream PR merge.

P.S. There's no need to post "me too / still happening" comments. It just creates noise for everyone and wasted time/resources (which slows down development... such as for bug fixes). Just upvote :+1: the initial report above (unless you have something useful to add that'll help resolve an issue of course). The :+1: is how, in part, we prioritize issues. Ironically no one has yet :+1: the initial report above. :)

Tschortsch0815 commented 2 months ago

Also existing in 29.0.4. I thought, that should be fixed? I disabled Preview in config.php: 'enable_previews' => true, --> 'enable_previews' => false, this didn't help. I also disabled MP3 Preview in the "EnabledPreviewProviders"-Section - also not better:

It even crashed my instance since disk was full. What can I do?
