The v0.2.20 release failed at the RPM step. rpm --addrequires does not
exist in the rpm that Ubuntu 24.04 ships, so the attempt to add the
missing libva requirement back to the package aborted the job.
The RPM is now built with rpmbuild from a generated spec instead of
through alien, which gives exact control over the requirements. They are
derived from the dynamic section of the binary that was actually built,
so the package always describes its own linkage rather than a hand
maintained list, and libva is added explicitly because the FFmpeg VAAPI
device opens it at runtime. The step fails if either the libva or the
FFmpeg requirement is missing from the finished package.
alien is no longer used and has been dropped from the runner packages.
