I’ve been trying to find an actual list of media file types supported by nextcloud web client.

Image Types with Thumbnails

Image Types without Thumbnails

Movie Types with Thumbnails

Movie Types without Thumbnails

Audio Types

Example: .avi extension is not supported as best I can tell. Is this true of all .avi formats, regardless of how they are encoded? I’m trying to encode my files to formats that will display properly in the web client. Any assistance is appreciated!

fyi, I noticed there have been some attempts in the past to support a wider range of media via this abandoned HLS Video Player app for Owncloud 8.
