cc @tobiasKaminsky this might also need additional work in the clients?

Step 1 would be iOS client sending/setting the meta data.

Step 2 would be the clients marking live photos as such combining the image and video on the visualization, specifics to be discussed with @nextcloud/designers, other platforms just display the image and add a 'live' icon to it.

Step 3 is to combine dav operations to be applied to both files.

Step 4 display live photos on all clients.

Step 4 would be the stretch goal

Step 2:

• only add "live" overlay to image
• https://fonts.google.com/icons?selected=Material+Icons:play_circle_filled:
• showing as one single entry as "jpg" with "live" overlay
• Android/iOS: in subline as first item "play icon with "live" word", then file size
• Server: showing only "play icon" on bottom right of thumbnail

Step 3:

• do operations on server, but only on "live photo" capable clients (iOS and Android)
• corner cases:
  • old client is deleting mov file -> server updates metadata so that jpg is a "plain" image
  • old client moves mov in another subfolder -> still works due to file id

For Step 4: https://support.apple.com/guide/iphone/edit-live-photos-iphd8dbb3291/ios

• when click on it, it will once play the short video, then stops and shows image
