I'll try to solve this problem as soon as possible

EmixamPP avatar Dec 04 '23 13:12 EmixamPP

Valgrind reports nothing, so honestly, I don't know what's causing this segfault

EmixamPP avatar Dec 06 '23 19:12 EmixamPP

Hey, please try the v6 https://github.com/EmixamPP/linux-enable-ir-emitter/pull/154. There is a bot comment with a link to the tarball. Please uninstall any existing version first:

sudo rm -rf /usr/lib64/linux-enable-ir-emitter \
/usr/bin/linux-enable-ir-emitter \
/usr/lib/systemd/system/linux-enable-ir-emitter.service \
/etc/udev/rules.d/99-linux-enable-ir-emitter.rules \
/usr/share/bash-completition/completitions/linux-enable-ir-emitter \
/etc/linux-enable-ir-emitter

Execute sudo linux-enable-ir-emitter -v configure And paste here the content of the file which is inside /etc/linux-enable-ir-emitter, from this point I can explain you how to manually tweak any instructions of your camera.

Hi,

first of all thank you for working on this. My setup is a ThinkPad X1 Yoga gen 8 which has a intel ipu6 system. It seems that the camera is not "connected" via USB but rather directly PCI.

v4l2-ctl --list-devices
ipu6 (PCI:pci:pci0000:00):
        /dev/video1
        /dev/video2
        /dev/video3

        /dev/video5
        /dev/video6
        /dev/video7
        /dev/video8

ipu6 (pci:pci0000:00):
        /dev/media0

Intel MIPI Camera (platform:v4l2loopback-000):
        /dev/video0

/dev/video0 is the main camera and now properly working via a v4l2loopback.

I receive the same segmentation fault as the original author. I tried almost all versions v5 and v6 either the pre-compiled or self compiled. As the output is not very comprehensive, is there a way for a more verbose version? Interestingly I have no file in

/etc/linux-enable-ir-emitter/

It looks to me that the segmentation fault happens early on.

Thank you

What is your exact CPU reference? I'm wondering if this is not related to the SIMD extensions (https://en.wikipedia.org/wiki/Streaming_SIMD_Extensions) that opencv uses.

EmixamPP avatar Jan 17 '24 10:01 EmixamPP

Concerning the verbosity, there is the -v option, but indeed I should output more debug information. I will work on that.

Concerning the verbosity, there is the -v option, but indeed I should output more debug information. I will work on that.

This I was already using. As said, maybe it needs some print line before even something is happening :)

klinkigt avatar Jan 17 '24 21:01 klinkigt

I've added a bunch of new debug messages, could you provide me the outputs of the command you execute?

EmixamPP avatar Jan 19 '24 00:01 EmixamPP

Thank you. I recompiled and tried the new version and receive:

WARNING: The camera /dev/v4l/by-path/pci-0000:00:05.0-video-index1 is not in gray scale. This is probably your regular camera.

resulting in a segmentation fault again. The output is the same for all cameras (beside 0 which is my main webcam) As for the error message. Not sure, maybe newer systems provide an RGB image instead of grayscale?

klinkigt avatar Jan 19 '24 05:01 klinkigt

OpenCV fails to determine automatically the resolution to use, you have to specify it using the options --height and --width.

resulting in a segmentation fault again.

After the exception you showed, there is a segfault message printed?

Not sure, maybe newer systems provide an RGB image instead of grayscale?

Correct. We can see the in v4l2-ctl -d /dev/video1 --list-formats-ext that the last mode says that the camera can be in grayscale, but I don't know I have to do with OpenCV to select it since this is a pci camera. Usually with usb one, this is the resolution that drives this choice.

I'm not 100% sure that OpenCV supports pci camera for VideoCapture? Or maybe I need to do things differently? I will investigate in the coming days, but if you find something, please feel free to share it with me.

EmixamPP avatar Jan 19 '24 20:01 EmixamPP

Hi, yes, after the exception there is still a segmentation fault. Sorry for not pasting this part, as it was in German. I also tried with setting the image size but no success here either. I think the direction that PCI devices are the issue might be correct. I had a lot of trouble making the main camera work with said loopback device. But as this is working now, I guess the drivers are correct.

klinkigt avatar Jan 20 '24 01:01 klinkigt

I've pushed modifications that will explicitly select the grey mode of a camera if multiple possibility exists (like in your case). But this will not fix the height and width problem I think.

EmixamPP avatar Jan 22 '24 20:01 EmixamPP

Thank you for update. First I was thinking I had a problem with compiling, but the error is completely the same (not in gray scale) It seems like that opencv just cannot work with this cameras at all. Maybe it will have to make a similar trick as with my main camera, looping it back with v4l2loopback. But is somehow strange that those cameras are listed under /dev/ but not useable. Something seems to be missing. I will try ti dig deeper in hope to find something.

klinkigt avatar Jan 26 '24 04:01 klinkigt

Ok, it seems there is nothing we can do here. It seems Intel does not want to support the IR camera: https://github.com/intel/ipu6-drivers/issues/33#issuecomment-1257402117 I apologize for bringing up this issues in this topic.

klinkigt avatar Jan 29 '24 07:01 klinkigt

Hi, just trying this tool out in order to use Howdy. I'm on a Lenovo ThinkPad T16 Gen 1 (AMD Ryzen™ 7 PRO 6850U with Radeon™ Graphics × 16) running Fedora 39.

  1. On the latest stable version 5.2.4, my IR camera flashed for a while and a prompt came up to confirm if I saw flashing (which i said no to) before I received a segmentation fault.

  2. I also rebooted and ran it in manual mode. I answered no to it flashing for all prompts. It did show an error "terminate called after throwing an instance of 'cv::Exception' what(): OpenCV(4.9.0) /home/runner/work/linux-enable-ir-emitter/linux-enable-ir-emitter/opencv/opencv-4.9.0/modules/highgui/src/window.cpp:971: error: (-215:Assertion failed) size.width>0 && size.height>0 in function 'imshow'"

I've just pushed multiple improvements, and one specific for the imshow exception. Please use the version provided in the PR #154 (see the bot comment).

If it stills segfault, could you try three things:

  • Add -g to the configure command: linux-enable-ir-emitter configure -g
  • Specify the width and height resolution of your camera (see v4l2-ctrl outputs) using --width and --height: linux-enable-ir-emitter --width <> --height <> configure
  • Both in the same time : linux-enable-ir-emitter --width <> --height <> configure -g

So the latest version does not segfault on my machine, but it does hang forever (never exits). I can see it has left the main camera on (white light on my laptop is on), but the IR camera isn't on (can't see the red light). I tried -g but it says that's not a valid argument. I also tried --width and --height which it said were not valid. the help suggested -w and -t were width and height so I did try passing -w 640 -t 360 for one run, which didn't help (not sure which resolution to pass? that's the only resolution reported by the IR camera in the v4l output).

x@thinkpad-t16-gen-1:~$ sudo linux-enable-ir-emitter -g configure

If the segfault problem is resolved, please let's open a new issue using the configuration has failed template. Like this, I can give proper help to every of you.

Note that the tool will not hang forever, if you enable verbosity (-v, as requested in the issue template) you will see outputs

But first, could you reinstall again the tool version v6? I've fixed an issue with the boot service.

Thanks for your help!

Hmm I take it back, the segfault is intermittent. I've tried the latest build. It either hangs forever (well, I've let it sit for 5-10min), or finally segmentation faults. I am running with -v and -g:

For my machine (Lenovo Thinkpad AMD T16 Gen 1), what happens is at the point it asks if its flashing, the camera indicator and the IR emitter turn on solid until I answer No. Then throughout each of the first 10 tests, both the IR emitter and camera indicator turn on and off together. Then when it reaches the end, the camera indicator comes on permanently while it hands and then eventually dies.

Apologies for taking so long to get back to you on this ticket. Got sidetracked with the holidays. I really appreciate you helping with this. This is a great project.

I don't appear to be getting the segmentation fault with the latest v6 so that's good. It's now just hanging. It runs and I start to see the IR camera light up after video2 (I think, it happens quick). However it comes on. I did let it run for a few minutes and then halted it because it doesn't seem to stop.

$sudo linux-enable-ir-emitter -v configure -g DEBUG: Executing configure command. INFO: Stand in front of and close to the camera and make sure the room is well lit. INFO: Ensure to not use the camera during the execution. DEBUG: Checking if /dev/video0 is a greyscale camera. DEBUG: Checking if /dev/video1 is a greyscale camera. DEBUG: Checking if /dev/video2 is a greyscale camera.

I did also try running it with -g and -m but that didn't seem to change anything.

If you'd like I can open a new ticket for the configuration not working since it seems for me the segmentation fault at least is resolved.

azblurbit avatar Feb 09 '24 18:02 azblurbit

I've published new commits with again better logging for me to identify exactly where the segfault happens, and why the process seems stuck.

Could you please both try again with this new version? I hope after that I will be able to provide an answer to your issues!

EmixamPP avatar Feb 10 '24 16:02 EmixamPP

I seemed to have gotten the same sort of issue. Are there logs being written to anywhere now in the new version that I can grab?

Also I'm sort of new to github so I did download the right tarball, correct? image

Assuming I did I got the same sort of error with Segmentation fault:

$sudo linux-enable-ir-emitter -v configure DEBUG: Executing configure command. INFO: Stand in front of and close to the camera and make sure the room is well lit. INFO: Ensure to not use the camera during the execution. DEBUG: Checking if /dev/video0 is a greyscale camera. DEBUG: Checking if /dev/video1 is a greyscale camera. DEBUG: Checking if /dev/video2 is a greyscale camera. Segmentation fault

Sorry for the late reply @azblurbit, I forgot to tell you to uninstall the v5 version before, please consult the README.md

EmixamPP avatar Feb 21 '24 19:02 EmixamPP

It has been merged on master. You can directly download this v6 beta version here: https://github.com/EmixamPP/linux-enable-ir-emitter/releases/tag/6.0.0-beta

EmixamPP avatar Mar 17 '24 21:03 EmixamPP

I have been encountering a failure at the same place using v6 beta on my thinkpad z13 with IMC integrated IR DEBUG: Instruction applied: unit: 4, selector: 3, control: 1 /usr/include/c++/11/bits/stl_vector.h:1063: std::vector<_Tp, _Alloc>::const_reference std::vector<_Tp, _Alloc>::operator[](std::vector<_Tp, _Alloc>::size_type) const [with _Tp = int; _Alloc = std::allocator<int>; std::vector<_Tp, _Alloc>::const_reference = const int&; std::vector<_Tp, _Alloc>::size_type = long unsigned int]: Assertion '__n < this->size()' failed. Aborted this is where it hangs and eventually aborts requiring a reboot. Any ways to skip this instruction?

Any ways to skip this instruction?

Yes you can! Edit the yaml configuration file that is in /etc/linux-enable-ir-emitter, find the item with the fields unit: 4, selector: 3, control: 1, then change the field corrupted: false to true

EmixamPP avatar May 06 '24 09:05 EmixamPP

@hulilikii see #172, use the --manual option

EmixamPP avatar May 12 '24 08:05 EmixamPP

Thanks for the help. I was successful using the config file and setting any instructions that crashed the camera as true. Seems to work fine now after configuring.

hulilikii avatar May 12 '24 12:05 hulilikii

I might be that both the assertion error and the segfault are related. If so, in the PR #176 you can find a bot comment with a link to a tarball and installation instructions that should fix the issue.
