m2vrequantiser was a useful package for quickly reducing the size of
video files so that they would fit onto a DVD, but about ten years ago
it started giving corrupt results when used on 64-bit platforms. A new
version appeared, and I used a local build-from-tarball, but it never
made it into the rpmfusion repos; they still have a version from 2003.
That seems a pity - although I haven't noticed cries of distress.
I only noticed this when I 'randomly' picked a smallish src.rpm for
(currently failing) tests of 'mock --chain'
