I wanted to enable video thumbnails so I installed ffmpeg in my container image using a Dockerfile and added this to my config.php:
'enable_previews' => true, 'enabledPreviewProviders' => array ( 'OC\Preview\Movie', 'OC\Preview\PNG', 'OC\Preview\JPEG', 'OC\Preview\GIF', 'OC\Preview\BMP', 'OC\Preview\XBitmap', 'OC\Preview\MP3', 'OC\Preview\MP4', 'OC\Preview\TXT', 'OC\Preview\MarkDown', 'OC\Preview\PDF' ),
This works both in docker version (if you install ffmpeg) and on regular installs BUT the moment you add this block of code to your config webp previews stop working! I have added ‘OC\Preview\WEBP’ to the array to see if works but it doesn’t. If I remove this block of code from the config file webp previews start working again but video previews do not. Anyone knows how can I have both webp and video previews working at the same time?
