vdpau for proprietary NVIDIA driver missing?

[tazmo]

Please correct me if I am missing the obvious but is the deb package to use vdpau with NVIDIA drivers missing in Kubuntu 20.04?

I have a Kubuntu 18.04 (using vnidia's drivers) and vainfo shows the following:

$  vainfolibva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: Found init function __vaDriverInit_1_0
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.1 (libva 2.1.0)
vainfo: Driver version: Splitted-Desktop Systems VDPAU backend for VA-API - 0.7.4

 VAProfileVC1Main                : VAEntrypointVLD
 VAProfileVC1Advanced            : VAEntrypointVLD

vainfo in 20.04 shows:

$ vainfo
libva info: VA-API version 1.7.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

Which Kubuntu 20.04 package contains /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so

I can't seem to find it.

Any help or pointers would be appreciated.

Thanks,
Bob

The file /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so is in the following Kubuntu 18.04 deb pkg:

ii  vdpau-va-driver:amd64                          0.7.4-6ubuntu1               amd64                        VDPAU-based backend for VA API

Kubuntu 20.04 doesn't seem to have that package available:

$ apt search vdpau-va-driver
Sorting... Done
Full Text Search... Done
$

Run the command

vdpauinfo

To the best of my knowledge, a standard kubuntu install has the packages.

The encode/decode abilities are packaged slightly differently in 20.04 in nvencode/nvdecode. Try installing the nvidia-utils package in 20.04

Check Muon. My 20.04 has 4 of the 6 vdpau entries installed (not including vdpauinfo, by the way)

It does appear to be missing... see here:

Downloaded and installed 18.10 deb package from here which appears to work on Kubuntu 20.04.1:

FWIW
