I think https://gitlab.gnome.org/GNOME/cheese/-/issues/28 "Cheese only
uses video/x-raw formats, and not image/jpeg" better matches the heading
of this issue, so I have added it as a tracked bug.

It is fixed, but Ubuntu-20.04 is still affected. Live image with 21.04
fails to boot on the affected laptop (AMD Ryzen), so unsure concerning
bug status in the latest distro.

Title:
  Cheese detects only low-res YUYV stream from camera

Status in Cheese:
  Unknown
Status in cheese package in Ubuntu:
  Triaged

Bug description:
  Cheese v3.30.0 (3.30.0-0ubuntu1)
  Xubuntu 18.04 LTS

  Cheese detects and reports/offers/accesses ONLY the resolutions in the
  YUYV stream, index 1, which results in low-res video and especially
  (what I use the cam for) still images. Previously, in 16.04 LTS,
  everything was working perfectly with Cheese; for example, it offered
  and accessed the 3264x2448 stream, which is what I'd been using.

  >>>  Currently, guvcview and VLC report/offer/access/display both
  streams and all resolutions perfectly.
