ffmpeg selecting GPU: Intel Xe and Nvidia

by |Published

I have Nvidia RX A1000 and Intel Xe on my computer.

When trying to use qsv

ffmpeg.exe -i "Recording.mkv" -c:v av1_qsv -c:a copy out.mkv

I get the error

Trying to initialize the device with

ffmpeg.exe -init_hw_device d3d11va=qsv:MFX_IMPL_hw_any -hwaccel qsv

ffmpeg picks the Nvidia GPU

[AVHWDeviceContext @ 00000182bc06d600] Using device 10de:25bc (NVIDIA RTX A1000 6GB Laptop GPU).
Hyper fast Audio and Video encoder

How can I choose Intel Xe instead?
