I have not succeeded yet to configure ffmpeg QSV access to an enabled
iGPU onboard an Intel Core i7-6700K (Skylake). This is a legacy,
rebuilt workstation with additional, discrete Nvidia GeForce GTX 960 GPU
on a MSI-Z170-A Pro mobo.
Any suggestions how to solve this?
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).

3) and also tried to apply the answer from
https://stackoverflow.com/questions/44747381/i-cant-use-hw-encoder-of-qsv-by-ffmpeg#47145215
<https://stackoverflow.com/posts/47145215/timeline>
It looks like ffmpeg is looking in its list of devices for a qsv
type device and not finding it. You can create a ffmpeg hardware
device with -init_hw_device qsv=qsv:MFX_IMPL_hw and then choose it
with -hwaccel qsv -hwaccel_device qsv. You should only need to do
the init once.
ffmpeg -hide_banner -init_hw_device qsv=qsv:MFX_IMPL_hw
-hwaccel_device qsv -hwaccel_output_format qsv -i
h264_8bit_yuv420p.mp4 -f null -
