I have not succeeded yet to configure ffmpeg QSV access to an enabled

Any suggestions how to solve this?
You can use vainfo to find the Intel gpu device correctly:
"vainfo --display drm --device /dev/dri/renderD12X"
Then specify device in ffmpeg cmdline with "-qsv_device
/dev/dri/renderD12X"
BTW, for legacy platforms, suggest to use libvpl with Media SDK for the
runtime implementation:

@Fei, thanks for your suggestion that hopefully will probe me in the
right direction.
Right now, I will be absent from my Skylake workstation a week or two,
before I can test more directly on it. But I did preserve some more
output I will add and refer to below.
In the meantime I also can do a bit indirectly tests on my available
Kaby Lake XPS-13 with UHD 620 iGPU and a similar system installation:
vainfo --display drm --device /dev/dri/renderD12X
Trying display: drm
Failed to open the given device!
As this don't find any device on Kaby Lake, I expect I rather have to
put in a number "8" instead of "X" as found on Kaby Lake(?)
ls /dev/dri
by-path card1 renderD128
When I try
vainfo --display drm --device /dev/dri/renderD12*
or
vainfo --display drm --device /dev/dri/renderD128
This simingly output just the same as "vainfo" alone on KabyLake.
And I have the latter preserved also from Skylake as follows:
vainfo

In addition also also preserved output on Skylake from two other tools,
"drmdevice" and "drm_info" as follows.

If /dev/dri/card2 and /dev/dri/renderD129 refer to the Skylake HD 530 iGPU
(and /dev/dri/card1 and /dev/dri/renderD128 refer to the Nvidia GPU),
I cannot understand why the initial, second ffmpeg command in section 2)
below did report errors?
Possibly syntax error or something else?
My tested ffmpeg code lines and system information below.
1) Tested first this simple ffmpeg decode bencmark code line from
https://trac.ffmpeg.org/wiki/Hardware/QuickSync#Decode-only
This works fine on single GPU Caby Lake/UHD 620 and on Alder Lake/Arc
A750, but on Skylake with dual iGPU HD 530 and a Nvidia GeForce GTX
960
card, these errors are reported:

2) Additional tests where I experimented to apply suggestions from
https://trac.ffmpeg.org/wiki/Hardware/QuickSync#Transcode
-qsv_device is an qsv customized option can be used to specify
a
hardware device and avoid the default device initialization
failure
when multiple devices usable (eg: an Intel integrated GPU and an
AMD/Nvidia discrete graphics card).
