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' https://repology.org/project/m2vrequantiser/versions John P
