Migrated from another router to AXT1800 and then a huge surprise was waiting for me. There is no kmod-video-uvc in the firmware! And I have video surveillance organized on it. I wonder what else isn’t there? Is this exactly openwrt? What is the problem with compiling all the kernel modules at least?
So what do I do now? Declared openwrt, the composition of openwrt is approximately known to me. That’s why I bought this router, without openwrt and all its features, I just don’t need it.

But it does not work. No /dev/video0
lsmod | grep uvc is empty.
root@GL-AXT1800:~# modprobe uvcvideo
failed to find a module named uvcvideo
Have you got something in lsmod after install?
Compared with rpi4 (arm64) kmod-video-uvc has 45 KB size.
On AXT1800 it has 891 B in size. 
I tested. It does not work. Let me ask developers.

It is fixed. Can you pls try?
opkg update
opkg install kmod-video-uvc
opkg install kmod-video-videobuf2
No change.
And what has changed at all? I didn’t notice any changes. The size of the ipk file is the same…
https://fw.gl-inet.com/releases/v21.02-SNAPSHOT/kmod-4.0.2/arm_cortex-a7/ip60xx/kmod-video-uvc_4.4.60-1_arm_cortex-a7.ipk does not contein the module (uvcvideo.ko).
You should use opkg and opkg install as I said.
Because the new module is
I did, but it didn’t work.
And it worked like this:
opkg install http://download.gl-inet.com.s3.amazonaws.com/releases/v21.02-SNAPSHOT/kmod-4.0.2/arm_cortex-a7/ip60xx/kmod-video-uvc_4.4.60-2_arm_cortex-a7.ipk
opkg install kmod-video-videobuf2
And it finnaly works!

v4.2.1r4 is having the same issues again and the new driver is not working from this thread
