## Tips & Tricks

### Generate password/secret key
```sh
openssl rand -base64 32
```

### Enable HEIC & MOV previews

1. Make sure that Preview Generator app is installed
2. Add this section to the `config.php`
  ```php
    'enable_previews' => true,
    'enabledPreviewProviders' => [
      'OC\Preview\PNG',
      'OC\Preview\JPEG',
      'OC\Preview\GIF',
      'OC\Preview\HEIC',
      'OC\Preview\BMP',
      'OC\Preview\XBitmap',
      'OC\Preview\MP3',
      'OC\Preview\TXT',
      'OC\Preview\MarkDown',
      'OC\Preview\OpenDocument',
      'OC\Preview\Krita',
      'OC\Preview\Movie',
      'OC\Preview\MKV',
      'OC\Preview\MP4',
      'OC\Preview\AVI',
      'OC\Preview\MSOffice2003',
      'OC\Preview\MSOffice2007',
      'OC\Preview\MSOfficeDoc',
      'OC\Preview\PDF',
      'OC\Preview\SVG',
    ],
  ```

3. If you don't see the previews, try running this command:
```sh
docker-compose exec -u www-data app bash -c ."/occ preview:generate-all -vvv"
```

4. For video previews you need to install ffmpeg, like so:
```sh
docker-compose exec app bash -c "apt update && apt upgrade -y && apt install -y ffmpeg"
# optionally add imagemagick and ghostscript
```
5. This will not persist so it must be run every time the container restarts...
6. Alternative is to manually build docker image :-|


### Bookmarks previews
For bookmarks previews it's required to have a screenshotting service.
[Screenly](screenly.md) can be easily self-hosted.
