cheese does no more work with elder USB webcams
This is because libv4l2 code has been disabled by default with gstreamer: https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/issues/644
my webcam:
lsusb
Bus 006 Device 002: ID 093a:2600 Pixart Imaging, Inc. Typhoon Easycam USB 330K (newer)/Typhoon Easycam USB 2.0 VGA 1.3M/Sansun SN-508
The webcam works with guvcview and vlc but not with Cheese.
