Video previews are generated but not shown

Hi,

I generated all previews (with the inital command):

sudo -u www-data php /var/www/nextcloud/occ preview:generate-all -vvv

And they are done:

My config:

  'preview_libreoffice_path' => '/usr/bin/libreoffice',
  'enable_previews' => true,
  'enabledPreviewProviders' =>
   array (
      0 => 'OC\\Preview\\TXT',
      1 => 'OC\\Preview\\MarkDown',
      2 => 'OC\\Preview\\OpenDocument',
      3 => 'OC\\Preview\\PDF',
      4 => 'OC\\Preview\\MSOffice2003',
      5 => 'OC\\Preview\\MSOfficeDoc',
      6 => 'OC\\Preview\\Image',
      7 => 'OC\\Preview\\Photoshop',
      8 => 'OC\\Preview\\TIFF',
      9 => 'OC\\Preview\\SVG',
     10 => 'OC\\Preview\\Font',
     11 => 'OC\\Preview\\MP3',
     12 => 'OC\\Preview\\Movie',
     13 => 'OC\\Preview\\MKV',
     14 => 'OC\\Preview\\MP4',
     15 => 'OC\\Preview\\AVI',
   ),

Still it does not show preview pictures for Videos when I browser the media.
Did I forget a configuration?

Thanks,
Dennis

Start by reproducing the reported behavior with the preview:generate-all -vvv command and the listed enabledPreviewProviders configuration, focusing on the MP4, AVI, and Movie providers. Trace whether generated video previews are available to the media browser; done means identifying the missing behavior or configuration needed for video preview images to appear.
