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 This email message and its attachments are confidential and/or privileged information.
