HEIC/HEIF Fedora 42

H265 video support in VLC:

  1. Follow https://rpmfusion.org/Howto/Multimedia
  2. Then install libavcodec-freeworld: dnf install libavcodec-freeworld
  3. Install VLC from RPM Fedora Linux. Not flatpak! The flatpak version doesn’t work with this!

  1. dnf install libheif-freeworld
  2. dnf install heif-thumbnailer
  3. (optional) dnf install ffmpegthumbnailer (get thumbnails in Nautilus also for MP4, MOV etc.)
  4. Log out/in
