webcam apps not functionng well

Cheese and guvcview  webcam apps are both inoperable :

1)Cheese : 

Code: [Select]
$ cheese

(cheese:7361): dbind-WARNING **: 12:22:07.327: Couldn't connect to accessibility bus: Failed to connect to socket /run/user/981/at-spi/bus_0: Permission denied

(cheese:7361): GLib-CRITICAL **: 12:22:07.663: g_strsplit: assertion 'string != NULL' failed
Segmentation fault         cheese
*


2) guvcview :

Code: [Select]
$ guvcview
GUVCVIEW: version 2.2.1
V4L2_CORE: ERROR opening V4L interface: No such file or directory
GUVCVIEW (1): Guvcview error

(guvcview:7293): Gtk-WARNING **: 12:21:33.108: Theme parsing error: <data>:1:17: not a number

(guvcview:7293): Gtk-WARNING **: 12:21:33.108: Theme parsing error: <data>:1:31: Using Pango syntax for the font: style property is deprecated; please use CSS syntax

Normally working webcam was plugged into the USB port, for both run tests.

I had similar issues with cheese, webcamoid, zbar, python opencv and some other webcam app I tried from the AUR. From looking around I thought this might be related, but not sure: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4842 Do you also use pipewire?
