This module uses the Media Thumbnails framework to create media entity thumbnails for jp2 files.
That way you can add the media entity 'thumbnail' field to Views or Media entity display modes, optionally add an image style and get preview images for jp2 files.
Requirements
- drupal/media_thumbnails
- ImageMagick php extension (imagemagick would need to be installed with jp2 support. Please see here for additional info.)
