Cheese detects only low-res YUYV stream from camera

[Andrew Gerald]

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.

I forgot to add that on the Cheese reference page...
https://developer.gnome.org/cheese/stable/cheese.html
...under "Invocation: cheese takes a list of options as arguments: Options:" a command line switch is documented that supposedly permits selecting the video device...
"--device=DEVICE, -d DEVICE Use the supplied DEVICE as the video capture device."
...but this has no effect, and even when entering a nonexistent video device (or random characters) no error message is returned; apparently this functionality is missing.
I've tried all permutations of video device, ex- "/dev/video#" and just "video#"

[Andrew Gerald (co6aka)]

Here's the problem:
https://gitlab.gnome.org/GNOME/cheese/issues/4
Cheese uses "ID_V4L_PRODUCT" to differentiate video devices...
My camera and others have multiple video streams which are enumerated as "video0" "video1" "video2" etcetera.
In all instances/streams "ID_V4L_PRODUCT" is the same...

[Andrew Gerald (co6aka)]

Any hope of this being addressed? It makes Cheese essentially useless for multi-stream cameras because a particular stream cannot be selected.

[Sebastien Bacher (seb128)]

Thanls for the bug report & upstream reference

[Andrew Gerald (co6aka)]

Thank you!

Cheese should changed to search for and enumerate, or manually select, cameras by /dev/device#, such as for example:

$ cheese -d "/dev/video1"

Instead of the way it's currently programmed, such as for example:

$ cheese -d "Secret Squirrel Webcam"

(The contents of the "ID_V4L_PRODUCT" variable.)

OR: Perhaps the combination of both methods should be employed to find and enumerate ALL devices and streams. Perhaps like this:

"Secret Squirrel Webcam (video0)"
"Secret Squirrel Webcam (video1)"
"Secret Squirrel Webcam (video2)"
"Some Other Camera Device (video3)"

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.
