Bug Description
The device is properly detected but it seems there are still issues with gstreamer plugin. When I try to run cheese I get the following error message:
../src/
(cheese:3769): cheese-WARNING **: 08:02:37.506: Failed to allocate required memory.: gstv4l2src.c(660): gst_v4l2src_
Buffer pool activation failed
With VLC I get
stefang@capella:~$ vlc v4l2:///dev/video0
VLC media player 3.0.9.2 Vetinari (revision 3.0.9.2-

Hi, could you do:
$ sudo ln -s source_linux.py /usr/share/ apport/ package- hooks/source_ linux-oem- 5.13.py
$ sudo apport-collect 1943915
The first command will manually create package hook link for source package linux-oem-5.13 as it should be (but missed in the official deb). Then it will collect as much info as needed generally for kernel issues.
I'll also need your output for following commands:
$ apt-cache policy v4l2-relayd libipu6 libcamhal0 v4l2-relayd
$ cat /etc/default/
$ cat /etc/v4l2-relayd
