Would downgrading ffmpeg and/or libcamera be of any help?

Title:
  Intel MIPI Camera not working out of the box on 25.04 where it did on
  24.10

Status in ffmpeg package in Ubuntu:
  Confirmed
Status in libcamera package in Ubuntu:
  Confirmed

Bug description:
  From discourse post:
  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 --

  $ lsb_release -rd
  Description:    Ubuntu Plucky Puffin (development branch)
  Release:        25.04

  $ apt-cache policy libcamera-v4l2

  The cam util spews several errors + warnings, but does find the camera

  v4l2-ctl sees many ipu6 video devices.  This looks wrong, but I'm not
  sure what it should look like, and don't have a working system to
  compare against.

  $ v4l2-ctl --list-devices
