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) The files exist: drwxr-xr-x 21 root root 4096 Nov 1 19:29 /./ drwxr-xr-x 154 root root 12288 Nov 8 21:08 /etc/ -rw-r--r-- 1 root root 51 Apr 9 2020 /etc/vdpau_wrapper.cfg drwxr-xr-x 14 root root 4096 Mar 8 2023 /usr/ drwxr-xr-x 118 root root 4096 Nov 9 20:40 /usr/lib/ drwxr-xr-x 125 root root 122880 Nov 8 21:08 /usr/lib/x86_64-linux-gnu/ lrwxrwxrwx 1 root root 17 Mar 24 2022 /usr/lib/x86_64-linux-gnu/libvdpau.so.1 -> libvdpau.so.1.0.0 -rw-r--r-- 1 root root 18592 Mar 24 2022 /usr/lib/x86_64-linux-gnu/libvdpau.so.1.0.0 drwxr-xr-x 2 root root 4096 Sep 30 09:40 /usr/lib/x86_64-linux-gnu/vdpau/ lrwxrwxrwx 1 root root 23 Mar 24 2022 /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_trace.so.1 -> libvdpau_trace.so.1.0.0 -rw-r--r-- 1 root root 59544 Mar 24 2022 /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_trace.so.1.0.0 drwxr-xr-x 306 root root 12288 Nov 8 21:08 /usr/share/ drwxr-xr-x 145 root root 4096 Nov 8 21:07 /usr/share/bug/ -rwxr-xr-x 1 root root 553 Jan 6 2021 /usr/share/bug/libvdpau1* drwxr-xr-x 2302 root root 81920 Nov 8 21:08 /usr/share/doc/ drwxr-xr-x 2 root root 4096 Jul 27 09:19 /usr/share/doc/libvdpau1/ -rw-r--r-- 1 root root 1447 Mar 24 2022 /usr/share/doc/libvdpau1/changelog.Debian.gz -rw-r--r-- 1 root root 3208 Jan 6 2021 /usr/share/doc/libvdpau1/copyright Regards, David Koski [email protected]
