Please describe your bug

Add a AVIF poster and Jellyfin will just delivers it. Official web-wrapper app has no issue displaying the images

Flutter doesn't support avif (yet). So we need to convert avif-images to png or jpg.

flutter/flutter#61229

THX for quick response. That is a pretty said state for a format supported by all major browsers and Android for a few major versions.
The strange thing is the contours work for avif.

You can close this issue, because mainline jellyfin has no official support and other formats will be converted with thumbnail functionality.
