[Cin] Rendering, encoding and decoding with Nvidia

[David Koski]

I've started using CinGG-20230930-x86_64.AppImage and I'm getting the 
hang of the basics.  I have gotten my nvidia hardware engaged with 
Cinelerra for encoding but still the rendering is not all that great and 
my CPUs are loaded down.  On finding that I need environment variables 
to engage decoding, I thought maybe that is hindering my rendering.  So 
with the following setting I started a rendering job:

export CIN_HW_DEV=vdpau

Now I get an error:

recvmsg(22, Failed to open VDPAU backend libvdpau_nvidia.so: cannot open 
shared object file: No such file or directory

libvdpau is installed:

ii  libvdpau-va-gl1 0.4.2-1build2:amd64              VDPAU driver with 
OpenGL/VAAPI backend
ii  libvdpau1 1.4-3build2:amd64                Video Decode and 
Presentation API for Unix (libraries)
