I am stuck how to configure 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 idea and code modification below?

=====================================================================
Trying to test QSV via FFmpeg benchmark similar like this Vulkan code
ffmpeg -init_hw_device "vulkan=vk:0" -hwaccel vulkan
-hwaccel_output_format vulkan -i INPUT -f null - -benchmark
https://trac.ffmpeg.org/wiki/HWAccelIntro#Vulkan
cause an output error which reports: "device type qsv needed".
Intel Skylake with HD 530 graphics gen 9, should be capable to decode
and encode MPEG-2/H.264/H.265 according to
https://trac.ffmpeg.org/wiki/Hardware/QuickSync#HardwareSupport
ffmpeg -hide_banner -hwaccel qsv -hwaccel_output_format qsv -i
h264_8bit_yuv420p.mp4 -f null - -benchmark
[AVHWDeviceContext @ 0x557526873500] Error creating a MFX session: -9.

I have tried to define and add a qsv device according to the last
section here
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). One example on Linux (more details please see
https://trac.ffmpeg.org/ticket/7649 <https://trac.ffmpeg.org/ticket/7649>)
ffmpeg -hwaccel qsv -qsv_device /dev/dri/renderD128 -c:v h264_qsv -i
input.mp4 -c:v h264_qsv output.mp4
and also had a look at this answer
