Dell Precision 5480

[treiher]

Unfortunately, in contrast to #47 the webcam still does not work for me after installation. I'm using Arch Linux with kernel version 6.5.8-arch1-1 on a Dell Precision 5480. I used the state of today's main branch (698d5ad) for the installation. The camera works when executing test.sh. install.sh ran completely without any errors. After a reboot, the webcam still doesn't work. A "Virtual Camera" is detected, but there is no output (the screen just keeps being black when trying the WebRTC sample).

Any ideas why it doesn't work for me?

[treiher]

The problem seems to be caused by v4l2-relayd. I'm able to use the webcam in Chromium after running

sudo -E gst-launch-1.0 icamerasrc buffer-count=7 device-name=ov01a10-uf ! video/x-raw,format=NV12,width=1280,height=720 ! v4l2sink device=/dev/video8

(as described in https://github.com/stefanpartheym/archlinux-ipu6-webcam/issues/33#issuecomment-1762967139).

[stefanpartheym]

Hi @treiher, are you still having issues? If so, try to update to the latest kernel version and use a fresh clone of this repo to install the drivers.

[treiher]

Hi @stefanpartheym,

Unfortunately, the issue still persists with the latest kernel version and a fresh installation of the drivers using the current main (d3e96251bee388a40d863eac68b81ddc2c11016c). Even worse, the workaround mentioned in https://github.com/stefanpartheym/archlinux-ipu6-webcam/issues/48#issuecomment-1778778160 does not work anymore. :frowning_face:

Hi @treiher,

what kernel version are you currently on?

[treiher]

@stefanpartheym I have switched to the LTS kernel (6.6.x) after getting a kernel panic when booting with 6.7.x. v4l2-relayd still doesn't work for me, but I can use the webcam with the gst-launch-1.0 workaround mentioned above.

[stefanpartheym]

@treiher: Trivial question, but have you tried reinstalling the packages (from a freshly cloned repo)? Otherwise I really have no clue, why v4l2 fails tbh.

[fiskhest]

FWIW, also on a 5480 and I am unable to get my webcam running on 6.8.4-arch1-1 with the latest commit.

Yep, kernel v6.8.x and v6.9.x won't work. You need an LTS kernel, or wait for v6.10.x release (as mentioned in #80 and #82).

[fiskhest]

Are there any hints as to what else would be missing given a v6.10.x release installed on the system? I'm on 6.10.2-arch1-1 but was thus far unable to get a working internal camera setup.
