https://discourse.ubuntu.com/t/intel-mipi-camera-not-working-out-of-the-box-on-25-04-where-it-did-on-24-10/59072/1
The ipu6 camera on a Dell Precision 5480 worked out-of-the-box on Ubuntu
24.10, but no longer does on 25.04-beta. It was suggested on Discourse
that this might be a regression in libcamera. I personally don't
understand the v4l/libcamera stack well enough to triage / route.
Here's what I'm seeing --
`ffplay /dev/video0` produces a video test image instead of actual
video.
However, gstreamer is able to show a good video stream via --
$ gst-launch-1.0 libcamerasrc ! video/x-raw,width=1024,height=768 !
autovideosink
This is on 25.04 beta with libcamera 0.4 --
