Unable to stop the stream: Invalid argument

[ChrisChinh]

Hello,
please excuse any incorrect formatting, this is my first time using Github. I installed howdy using the aur package but when I run sudo howdy test I get:

Unable to stop the stream: Invalid argument

Press ctrl+C in this terminal to quit

Traceback (most recent call last):

    import cli.test
  File "/usr/lib/security/howdy/cli/test.py", line 78, in <module>
    overlay = frame.copy()
AttributeError: 'NoneType' object has no attribute 'copy'

Am I doing something wrong?
Thanks in advance for the support

@KelleyMcChes problemens with the cv2 python bindings perhaps?

[KelleyMcChes]

There are currently a few problems with the Arch package. I am working on it currently and should have it fixed in the next few days. @boltgolt @ChrisChinh

Great, thanks!

[KelleyMcChes]

I finally got howdy updated and the issue should be fixed. Don't forget to change /dev/videoX in the config file or you will get an error!

Great, thanks!

Is it possible for a multi-distro package to track the .SRCINFO and PKGBUILD files within the main repo? I find it a bit unnerving that such important files are not saved in the repository and are only available on AUR. I guess there is a chicken-egg problem with the sha256sums but that's only a small part of the files.

[KelleyMcChes]

The problem is that the .SRCINFO is generated dynamically with every new PKGBUILD. If there ever seems to be an issue with a new version and I have to modify the PKGBUILD by adding a package or something similar, the .SRCINFO will change and thus the sha256 of the package will change. There's a reason no package stores it's checksums inside the downloaded zip or tar file 😉

[boltgolt]

I get that there's a chicken-egg there, but it's weird to me that such an important file is only stored outside this repo.

I have the same issue when I update the kernel on Ubuntu 18.04 to 4.18 from 4.15.
Once i revert back to 4.15 everything works fine.

Error when using 4.18 and trying sudo apt update:

Unable to stop the stream: Invalid argument
VIDEOIO ERROR: V4L: can't open camera by index 1
Face detection timeout reached

Error when trying sudo howdy test:

Unable to stop the stream: Invalid argument
VIDEOIO ERROR: V4L: can't open camera by index 1

Ideas?

Following up on issues i forgot to reply to in august, are you still having this problem or did you fix it/uninstall Howdy?
