Hello,
I have a Dell Precision 5480 with a MIPI IPU6 camera. I have used it in the past on another distro with the usual DKMS modules + V4L2loopback and although unstable, it worked.
When installing Fedora 42, I noticed that it worked out of the box (even in the live CD of the KDE remix). But later on, I noticed that it only works for Firefox. I.e. the Mozilla GUM test shows me the video stream if I visit it in Firefox, but with Chromium, the browser claims that there is no webcam. A similar issue with the Zoom rpm package (no webcam found), and with VLC (there are 31 /dev/video? devices, but none seems work). If I install qv4l2, it finds a camera called IPU6, but the output stays black.
I’ve been reading the old posts about MIPI webcams (i.e. Webcam on Dell xps 13 plus (9320) Intel ipu6) but it does not seem to apply to Fedora 42 since F42 Change Proposal: X86 MIPI camera HW-enablement (self-contained), or maybe I did not understand something.
Can anybody link me to more updated documentation, am I just missing some package, or do I to try with the non-free drivers, and ditch the new method for now?
