[Cin] Rendering, encoding and decoding with Nvidia

[Phyllis Smith]

AppImage has some great advantages but also some disadvantages, one of
which is stated below from the manual:

There is an AppImage workaround that another user provided to solve this
library problem, but it is not for the casual user -

The laptop computer that I created the AppImage that you are using is an
AMD based computer running an older Fedora version 32 and has the following
installed:

> ./usr/lib64/libvdpau.so.1.0.0
> ./usr/lib64/libvdpau.so.1
> ./usr/lib64/libvdpau.so
> ./usr/lib64/vdpau/libvdpau_radeonsi.so.1.0.0
> ./usr/lib64/vdpau/libvdpau_radeonsi.so.1.0
>
which I "think" is included in the AppImage generated there.  (Andrew is
knowledgeable in this area but I am not, so further clarification may have
to come from him).
