I've compiled it and when I type: media-ctl --set-v4l2 '5:0[fmt:UYVY8_2X8/1920x1080@1/15]' I get Unable to setup formats: Inappropriate ioctl for device (25) When I type fswebcam -S 5 -d /dev/video0 -p YUV420P -r 1920x1080 test.jpg I get --- Opening /dev/video0... Trying source module v4l2... /dev/video0 opened. No input was specified, using the first. Unable to query input 0. VIDIOC_ENUMINPUT: Inappropriate ioctl for device

你好，请问你的编译报错是怎么解决的呢，我也遇到了同样的问题

Hi, I don't use this driver any more, you can use mainline mpi-csi-2 driver Read this: https://linux-sunxi.org/Linux_mainlining_effort https://bootlin.com/blog/initial-allwinner-v3-isp-support-in-mainline-linux/ But you will need kernel >= 5.14

I recommend use mainline bootlin CSI2 driver. This repo is one of my early work when there was no availabe driver for allwinner mipi-csi2.

You have to disable the CONFIG_VIDEO_SUN6I_CSI option that comes with the mainline kernel. Some code in this repo uses the same function names, thus the multiple definition compilation error.
