Parole (XFCE Video Player) Codec Error

Trying to play any MPEG-4 file I get an error. The error is: It is necessary additional software Parole needs Decoder 264H (Baseline Profile) in order to play the file. And despite into the Parole Window there is the button to install this plugin, nothing happens. The video is instead perfectly reproducible in VLC. I have installed all the plugins from Pacman repo. Do you have suggestions on this matter? Thanks and regards, -- Marco Calistri Build: openSUSE Tumbleweed 20231013 Kernel: 6.5.6-1-default - XFCE: (4.18.3)
