- x264/x265 are patent-encumbered and not in Fedora's own repositories:
install the RPM Fusion free release package first (over HTTPS from the
official mirror) so dnf can resolve them;
- Fedora 43 renamed the bindings: libdav1d-devel (not dav1d-devel) and
openjpeg-devel (not openjpeg2-devel);
- degrade like the apt branch when something is unavailable:
--skip-unavailable instead of failing the whole transaction.
Verified end-to-end in a fedora:43 container: the full list installs
(260 packages; x264 0.165 and x265 4.1 come from RPM Fusion). Arch's
package names were re-checked against the Arch package index (all
present).
