[video4linux2,v4l2 @ 0x558aa88de740] ioctl(VIDIOC_G_INPUT): Inappropriate ioctl for device

Would you please help me to resolve it.

BTW: My code is working in Windows 11 and MacOS.

I assume you're accessing a Webcam because of the v4l2.

Did you use the correct path for the camera? /dev/video0? /dev/video1?

Did the code work with other cameras? if so, then the webcam might need specific driver and its not a UVC.
