Webcam / video in AR750

postmaster · 2018-12-17T08:19:37.918Z

Dear all,
I’d like some help with the following. I have a GL-AR300M were I can hook up a simple USB webcam and see the video option.

I would like to do the same with an AR750: hook up a USB webcam and see the video. I cannot get it to work and don’t understand why this seems different with another GL-inet device. My AR750 is running the latest version 2.272, I rebooted the AR750 several times. In the upper menu I see settings, app repo etc etc, but no video. With dmesg I see

usb 1-1.2: USB disconnect, device number 4
usb 1-1.2: new high-speed USB device number 5 using ehci-platform

but no devices like /dev/video . I installed usbutils, and see this with lsusb, so the webcam seems to be recognized by the kernel:

Bus 001 Device 005: ID 046d:0825 Logitech, Inc. Webcam C270

Any help please?

We removed this feature from all our new products (include AR750) and new firmware.

webcam is difficult to use in the router.

User experience is not good.
Compatibility is huge headache.
This feature will remain in DIY level forever, no way to commercialize

so you need to install and config mjpeg-streamer by yourself and DIY according to the guide in OpenWrt.

Thank you, I agree in the reasons and am willing to use mjpeg-streamer or motion or whatever. But I’m missing a device like /dev/video. Can it be, this support for webcams is also already removed from the kernel?

In our Repo, search video and you should find some video kernel modules like the following

kmod-video-uvc
kmod-video

You need to install the webcam drivers.
