is the linter right about the ffmpeg meta bump revision?

[zlice]

Failed to install 'ffmpeg-devel' and 'mlt-devel-6.26.1_3'

this package has been removed. assume the ci stuff needs updated?

[zlice]

updated this but ffmpeg4 is broke on nv-codec-headers that removed a bunch of deprecated shit https://github.com/void-linux/void-packages/pull/55205#issuecomment-2919467527

This PR bifurcates and confuses the issues with how to handle our existing ffmpeg versions and whether there is merit in establishing an unversioned metapackage. These issues should instead be reconciled simultaneously.
