After digging around the internet I found that after installing the package "libvdpau-va-gl" to make the program work, I had to then unninstall the package "libva-vdpau-driver" that was causing conflicts. Only after that things worked fine.
PS. Thanks @tadly for the useless advice.

!!! Please do NOT flag the package out of date just because a new version has been release. !!!
Parsec self-updates and as long as the package still installs (no sha256 mismatch), there is no reason to update it in the AUR as the .deb actually is an older version.
