Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
  Void 5.11.11_1 x86_64 AuthenticAMD uptodate hold rrrrmmnDFFFF
* package:  
  libvpx6-1.10.0_1, ffmpeg-4.3.2_1

ffmpeg with libvpx6-1.10.0_1 seems to cause a ABI version mismatch:
`[libvpx-vp9 @ 0x55c640248fc0] Failed to initialize encoder: ABI version mismatch`

downgrading to libvpx6-1.9.0_1 fixes this issue - seems to be caused by ffmpeg built against older version. Rebuilding ffmpeg with new libvpx should fix the issue.
