Hey everyone…I’m a brand-new kstars user (just installed it all on Monday) but I’ve worked in computers back to the late 1970s. New to astro-photo as well…I have a MS “Lifecam Studio” webcam to experiment with – color 1080p, 30 fps, and 3micron pixels. But it’s not cooperating. Here’s my software: INDI Library 1.9.8 Kstars/Ekos 3.6.1 Here’s how I got it: $ sudo apt-add-repository ppa:mutlaqja/ppa $ sudo apt-get update $ sudo apt-get install indi-full kstars-bleeding My host system: $ uname -a Linux russ-mint 5.4.0-71-generic #79-Ubuntu SMP Wed Mar 24 10:56:57 UTC 2021 x86\_64 x86\_64 x86\_64 GNU/Linux I also installed a number of \*-dbg packages, per the “Read This Before You Post” message. My ekos profile only contains a single device, the CCD My first attempts failed immediately upon hitting the Connect button. (driver crash, either with webcam or v4l2 but kstars still running) I changed the permissions of /dev/video0 (sudo chmod +777 /dev/video0), and was then able to see settings for “Expose”, But ekos and kstars now crashed. Below is output from kstars log, indi log, and gdb running kstars: [2022-10-27T10:49:03.738 CDT INFO][org.kde.kstars] - Welcome to KStars 3.6.1 Stable [2022-10-27T10:49:03.738 CDT INFO][org.kde.kstars] - Build: 2022-10-19T15:03:43Z [2022-10-27T10:49:03.738 CDT INFO][org.kde.kstars] - OS: “linuxmint” [2022-10-27T10:49:03.738 CDT INFO][org.kde.kstars] - API: “x86\_64-little\_endian-lp64” [2022-10-27T10:49:03.738 CDT INFO][org.kde.kstars] - Arch: “x86\_64” [2022-10-27T10:49:03.738 CDT INFO][org.kde.kstars] - Kernel Type: “linux” [2022-10-27T10:49:03.739 CDT INFO][org.kde.kstars] - Kernel Version: “5.4.0-71-generic” [2022-10-27T10:49:03.739 CDT INFO][org.kde.kstars] - Qt Version: 5.12.8 [2022-10-27T10:49:04.352 CDT DEBG][org.kde.kstars] - Opened the User DB.

Hello, I had problems with crashes with V4L2, but they disappeared with the update of 22/10, you have the version of 19/10, try to update. Sylvain ---

so Update Manager said I could update from 6:3.6.1+202210191503 up to 6:3.6.1+202210271233 – did the update but no joy, same driver crashes. I removed-and-reinstalled, no joy. I used synaptic to completely remove all kstars and indi and data, then reinstalled from ppa. no joy. I even installed from snap…guess what? no joy. Next, I completely removed everything again, and installed with synaptic from ppa…kstars-bleeding and indi-full. It seemed to take a LOT longer than apt-get in a terminal. Still won’t run: “webacm driver failed to start” over and over. Looks like synaptic didn’t install indi-webcam, so I installed it. Now it runs, up to the point where indi control panel shows “Exposure” – for a couple of seconds, then it all crashes and ekos and kstars both disappear. The only entry I’ve ever seen that even looks like a real error is “Driver indi\_webcam\_ccd: Impossible IPState 4"” Ideas? ---

There are a couple things to try. First, make sure the camera works in Linux, with a program such as webcamoid (sudo apt install webcamoid), just to make sure the camera is functional. Second, there are actually two different webcam drivers in INDI. There’s INDI Webcam, and then there’s V4L2 CCD. Why? Don’t know. I think the INDI Webcam was written to support webcams other than v4l2 cameras, on Mac OS, but I could be mistaken. I’d try the V4L2 CCD driver instead. Here’s some documentation on using it: [https://indilib.org/individuals/devices/cameras/web-cameras.html](https://indilib.org/individuals/devices/cameras/web-cameras.html) ---

The built in camera works, and all my external webcams work in cheese, guvcview, etc. Neither webcam driver works with any of my webcams. I have two MS Lifecams and a Logitec. I have other standalone capture softwares (eg: AstroDMx Capture) and all the webcams work with those as well. ---

Hmm, I’m sorry to say that I am out of ideas. I plugged in a Logitech C920 webcam, ran the indi\_v4l2\_ccd driver, configured Ekos, and got this: ![logitech webcam.JPG](https://forum.indilib.org/uploads/default/original/2X/8/88b56dd238116d7061ddc2a50b830d65a16c6720.jpeg) It’s important to note that long exposures (anything more than about 0.2 seconds) aren’t supported by webcams. The driver gets around this by doing an internal live stack of shorter exposures. But you must enable that in the INDI control panel. The above image was taken with default settings in the INDI control panel, with a short .001 second exposure. But even when I tried long exposures, when I didn’t configure INDI, it just gave an error that I must configure it. I did what it told me to do, and got an image. Sorry I can’t be more helpful. ---

BTW, I couldn’t get indi\_webcam\_ccd to work with my camera. It either kept saying “not a video capture device” or “no such device”, even though it was set to /dev/video0, which has proper permissions. So I went with the indi\_v4l2\_ccd driver. ---

Thanks for trying! There must be something in my particular system that’s messing things up. I’ll keep looking! ---

BTW, I was able to get INDI Webcam driver to work. I was an idiot, I was trying to use /dev/video0, when the camera was in fact connected at /dev/video1. Once I set the right path to the camera, it fired right up, no issues at all. Sorry, I know that isn’t terribly helpful. Just letting you know that both drivers work for me with my Logitech C920 ---

Ok I think “2022-10-30T16:58:21: Driver indi\_webcam\_ccd: Impossible IPState 4” is one lead. Can you please debug the driver via Ekos Debugger? ```auto sudo apt-get -y install ekos-debugger ``` In Ekos, edit your profile and select Remote. After Ekos Debugger starts the INDI server with the correct webcam profile (INDI tab), then connect from KStars. If the drivers crashes, then you’ll get back the backtrace for it. ---

It took me a while, but I finally figured out that in spite of installing “ekos-debugger” you have to run “ekosdebugger” :oops: As soon as I hit “Connect” in ekos a small pop-up fired and instantly disappeared as all the kstars windows closed. I started kstars from the “KStars” tab within the debugger, but also got the same result when starting it from the linux app menu ekosdebug output attached: [ekos debugger output.txt](https://forum.indilib.org/uploads/short-url/qomtaIEqFv5UrKAQrF9rPpS3JcH.txt) (397 KB) ---

Can you clear all config? i.e. rm -rf ~/.indi/\* Then run the driver again. ---

After removing the contents of ~/.indi it went a little farther. It did NOT ask me if I wanted to keep a running indiserver the indi control panel now had tabs for “WCS” and “Streaming” closed the control panel and opened the CCD tab under the Sequence Queue are three buttons: Capture a preview, framing, and live video I don’t know what “framing” does, but capture preview and live video fire a pop-up that says “Connection to INDI host at localhost on port 7,624 lost. Server disconnected: -1” ekos did not crash, but indi stopped. not sure if it crashed, there was no “backtrace” offered Astrophotography is FUN! :lol: :lol: ekosdebugger outputs attached: [ekos debugger output 20221103-094438.txt](https://forum.indilib.org/uploads/short-url/n4WycYhcSYoCZmwKzbVeBdSR0gE.txt) (24.5 KB) ---

Thank you. I just realized we are talking about two different drivers. I asked Robert to take a look at this. Meanwhile, do you have the same issue when using “V4L2 CCD” driver? ---

yes, same for either webcam-type driver … I think since I was planning to get a ZWO ASI-174 anyway, I’d just go ahead and buy one and see it that works better…Thanks for all your help!!
