Everything working in firefox after installing libavcodec 59 and uninstalling ffmpeg 5mini and
Installed ffmpeg5 and removed ffmpeg4 ( I had libavcodec 56,57 and 58)
i+ | ffmpeg-5 | package | 5.1.2-15.1 | x86_64 | Packman
i | ffmpegthumbs | package | 22.12.1-1.1 | x86_64 | Main Repository (OSS)
i | ffmpegthumbs | package | 22.12.1-1.1 | x86_64 | openSUSE-20230129-0
