Automates everything to install kinect as a webcam

grandchild

Hi,

sorry for taking so long to get to this, and thanks for the script!
But I'm not sure about just dumping a script in the repo.

I'd find it better if these steps would be generalized to other distros (no apt) and broken up with explanatory sections in between. That wouldn't be a .sh file but rather an INSTALL.md or similar. If you don't feel like doing a proper writeup that's okay -- I might do that at some point.

This would be a better fit for the README. Not everyone runs Debian or Ubuntu.

Wouldn't these have to be run as root? Hint: The answer is not to run the whole script as root.

I feel this would be better as a separate file in this repository. so it can be cped.

This should be left to the user, not done in an install script.

SterlingButters · 2020-12-17T15:25:15Z

@grandchild I agree with most of your comments. I figured if I came up with the script myself I might as well share it i.e. my goal wasn't to make it work in general - it was just something I had already done. You are correct that the script is needed to be run as root - I know why this is disadvantageous but I just needed a "quick-fix". I am actually pretty unfamiliar with how to draft/use an INSTALL.md so I won't be of much help there. I also think at the very least the install script should ask the user if they would like the service enabled at boot (must easier to just confirm "y" than to type all that extra junk). I like the idea of the separate .service file - it also makes more sense in this application when hosted in a repo (not sure how you could do this with a single install script/file like I did)

grandchild · 2020-12-18T09:01:16Z

Hey, that's cool :)

I will just make an install.md from your script myself -- I really don't mind. I just wanted to check what your involvement in this is. If this is just a quick script, then you'll not mind. But people are sometimes more... possessive(?) about their code and want to do things themselves, that's why I asked :)

Thanks for the script again (and the systemd service) it'll serve as a nice starting point.

SterlingButters · 2020-12-18T16:02:25Z

Awesome! I'll be excited to see it implemented then! I don't care about ownership of this script particularly - credit is always nice but at the end of the day if it results in a better product for me to use then I am happy. Thanks for being a responsive dev - I always like to see that.

Note I had some problems with this script on one of the Ubuntu kernels and then when the kernel updated it worked again so idk what that was all about.

JakeSays · 2021-04-18T22:42:05Z

I would much rather have this as a usable script than as documentation. Scripts are almost always more likely to be updated than the docs.

vncscoelho · 2021-05-24T20:15:20Z

The script ran OK, except when tried to start the service. Ubuntu 21.04. Any idea?

Wondering if anyone is still working on this.

Anyway, I had the same error as @vncscoelho and the output of your command was
v4l2-kinect.service disabled enabled
