Mp4 previews are being correctly generated but not showing, except for trash folder [bug] #355

all dependencies seem to be ok. config.php is correctly configured previews generate without errors The proof that everything is working is that if i delete files, they correctly appear with a thumbnail in trasbin. All other folders miss previews. Looks like trash folder uses a completely different logic for thumbnail generation.

The issue is reproduceable in 25.0 all sub versions and in Beta 26

Thanks for the report.

Please confirm:

  1. There are no previews shown for files on the files app (outside of the trash bin).
  2. There are previews shown for files in the trash bin.

Correct, but this only true regarding mp4 files.

I am running into the same issue, kinda. When using local storage, I could see mp4 previews just fine. However, after setting up Idrive s3 as primary storage I can now only see mp4 previews in trash as described.

How to check whether those previews were generated?

bbx-github commented 3 months ago

I have the same issue with nextcloud: 28.0.3.2 and previewgenerator: 5.4.0

How to check whether those previews were generated?

I have a complicated method to check if previews for a specific file were generated:

  1. connect do database (ex mysql: $ mysql -u <dbuser> -p <dbname>
  2. extract fileid mysql> SELECT fileid, name FROM oc_filecache WHERE name = '<filename>';
  3. seach in filesystem: $ find /var/www/nextcloud/data/appdata_oc<rand>/preview -type d -name <fileid>
