Try setting the Intel display as the primary device.

Hi
I have a machine running Windows 10 that has 2 graphics cards in it,
an Intel HD Graphics 630 & an NVIDIA GeForce GTX 1060. The CPU
supports Quicksync & the monitor is plugged into the Intel Graphics card.
I'm using a variant of Anton Khirnov's 2015 qsvdec.c example.
If I have both graphic cards enabled in Windows then we I get to the line:
av_hwdevice_ctx_create(@FHWDecode.hw_device_ref,AV_HWDEVICE_TYPE_QSV,'auto',nil,0)
I get "Error initializing an MFX session: -3." If I disable the NVIDIA
card using the device manager the call is successful & things work
properly. To my untrained eye, it would appear like it's trying to
open a Quicksync session on the wrong card. Interestingly, when I
initialize a Quicksync enabled encoder (eg h264_qsv) it is always
quite happy to do that even when the NVIDIA card is enabled.
If I'm right about it trying to open a Quicksync session to the NVIDIA
card, is there a way of pointing at the correct videocontroller
without having to disable to card? I can identify which
videocontroller is the Intel card using WMI.
Best wishes
Fred
