A configuration have been found. Here is what you can do:
- activate the emitter at system startup : 'linux-ir-emitter boot enable'
- manually activate the emitter for one session : 'linux-ir-emitter run'

These commands don't work and should be:
linux-enable-ir-emitter boot enable
linux-enable-ir-emitter boot run

I have published what looks like the future version of the programme on the https://github.com/EmixamPP/linux-enable-ir-emitter/tree/pre-release branch.

This new version currently includes :

• linux-enable-ir-emitter fix command : can reset the config file and uninstall chicony-ir-toggle
• I tried to fix the unable to open a file descriptor error caused during boot. The problem is that the camera is not yet initialized and therefore not yet accessible. I've added the line ExecStartPre=/sbin/modprobe uvcvideo to the .service file. Since I don't have this problem, I can't test, I hope it works.

What I might consider adding: move the config file to the /etc folder.

My second announcement is that I am no longer using Manjaro and therefore I will not be able to properly maintain the AUR package. @komex will you take care of updating the package for new releases? (If so, don't worry I'll let you know when it's ready).

After installing linux-enable-ir-emitter, I entered the following for setting, but an unknown error occurred.

$ sudo linux-enable-ir-emitter -v configure

I remember having the same problem a while ago when another device(iPhone) was connected via USB, but this time it doesn't seem to be the problem because there is no connection except for the power line.

PS. I accidentally found out that there is no 'lsusb' command, installed usbutils(ArchLinux) and tried it, and confirmed that it works.

NOTE: this is an odd one, originally it worked however I think after running some howdy test and maybe linux-enable-ir-emitter test and CTRL+Cing midway the configuration does not work anymore and I cannot get the IR emitter to work, even after a reboot.

Which device did you used ?
ThinkPad X1 Carbon Gen 9

I have just published on a new branch a new utility that allows, in addition to before, to capture packets from the bus with wireshark. We just have to open the Windows VM.

@renyuneyun I noticed that your AUR package is still not up to date with the changes we discussed over 2 weeks ago. So I think in the end, it would be easier if I manage this AUR package.

Describe the bug

The following error is shown after running install.sh

install: cannot stat 'sources/autocomplete/%{name}': No such file or directory

Upon running sudo linux-enable-ir-emitter configure, the IR did not start flashing. I answered No about 10 times (and I don't have 10 cameras) and each time got:

Ioctl error code: -1, errno: 84
Illegal byte sequence.
Did you see the ir emitter flashing (not just turn on) ? Yes/No ? No

I saw my regular camera indicator flash the last several times (but not the IR camera).
How to reproduce

I followed the instructions from the readme (version b2172cf)

Additional info

• Distro: Ubuntu
• Version: 20.04.3 LTS x86_64 with 5.10.0-1051-oem kernel
• Version of linux-enable-ir-emitter: 3.2.3
• Version of python3: 3.8.10
• How did you install linux-enable-ir-emitter: bash

Today I tried with Ubuntu 21.10 and Fedora 35, the configuration process worked fine, IR leds activated and flashed OK, no issues.

Then activated boot enable, output was ok as well, nonetheless when booting the IR leds will never turn on, I reinstalled both distributions 2 times from scratch, same outcome.

This is very weird, because I have done this 20 times, always success at the first try, never a problem.

I'd like to improve to config for webcam on Lenovo X1C7. I've installed virtualbox and Windows 10 20.04 as guest and captured USB traffic.
Unfortunately I do not find step 8):

In the VM, go in the security options tab of the Windows settings and click on launch an improvement of the recognition of Windows Hello. A pop up is displayed and asks if we want to start the test, you can go back to Wireshark without having to go any further.

Maybe it's because I cannot setup Windows Hello Face?

This webcam should be compatible to Windows Hello but I think it's the problem with the driver from virtual box...
How did you solve this?

However, I could capture some USB traffic:

Setup Data
    bmRequestType: 0x21
    bRequest: 1
    wValue: 0x0200
    wIndex: 1 (0x0001)
    wLength: 48
    Data Fragment: 01000207151605000000000000000000200000600900f40b0000c0e1e400070000000000000000000000000000000000

but I'm not sure if these are the default values and they will change if I launch an improvement of the recognition of Windows Hello?

All Windows Hello cameras that i have come across have blinking IR emitters that do not necessarily sync with the camera framerate. Currently Howdy relies on analysing the darkness of frames to filter out these unlit frames. Filtering them out speeds up recognition as Howdy will only analyse well-lit frames that have a higher chance of success.

As you are much more knowledgable on the packets send to the camera from Windows Hello, do you think it would be possible to read the status of the emitters for each frame or even sync up this blinking with the camera?

I was trying to get updated to how to use this software, and figured out a saved configuration file needs to be generated/created first. One way to do so is to execute linux-enable-ir-emitter quick.
When drilling down to the source code, it looks like the generated configuration is saved to /usr/lib/linux-enable-ir-emitter/irConfig.yaml.

In my experience, the /usr/ directories are normally not modified by the user / user softwares, especially not for saving configuration files. Configuration files are usually saved under /etc/ or /var/lib/ (e.g. mysql/mariadb). Files under /etc/ are normally open for (admin) users to modify, and are normally human-friendly; files under /var/lib/ are normally not for the user to directly manipulate.
Though I have to admit there are some exceptions, particularly for apps in early development (e.g. mycroft).

I'm not an expert in that either, and there are no mandatory rules for that. Therefore, I'm bringing this up for discussion, and wait to see if others have better suggestions.

Is it a bug in your program, or a misconfiguration in pip ? And how could I repair that ?
Thanks in advance

On the auto-config branch, you can see an auto directory, as well as inside a python script auto-enable-ir-emitter.py that will test each configuration of config.json. If the C script runs without error, the user should confirm that the infrared emitter is working. If yes, the python script proposes to create the systemd service.

I will test the program a few more days and if there are no problems I will merge it with the master
Edit: the branches have been merged

@renyuneyun
You proposed to make an AUR package, personally I'm on Manjaro but I don't know if I'm going to be there for long, so it might be better if you took care of it. I don't know if I should create a new repo? Or this one is enough and I put you as a collaborator? Or we use your repo, I don't mind.

Any other help or comment is of course welcome.

Hello!

Hi, I used your script to enable the IR emitters with my laptop and Ubuntu 20.04, Howdy alone will not be able to, it works fine until I will reboot or shutdown the laptop, then at the next login after restarting, the white led from the camera will turn on and the IR emitters will stay off and of course face authentication will fail, any idea what could be the problem? Thanks

When I first configured this program, the infrared fill light flashed and red could be seen.

After I selected enable and restarted, the fill light could not be used.

After reinstalling the program, no red light is on when the configuration is found.

(I've tried it many times, but it doesn't seem to work)

Hi.
Your script is working properly in the current session. I can see the ir-leds blinking and facial recognition ends successfully. But after reboot it doesn't work. I have to restart the program manually. I have the latest version and Your fix https://github.com/EmixamPP/linux-enable-ir-emitter/wiki/Issues doesn't work for me. :~$ linux-enable-ir-emitter boot enable freezes and i have to strike Ctrl-C and launch "fix config" to make everything work again. Until restart...

Hi, first of all, thanks for your work,

The quick configuration work for me but it stops working after reboot. It's seems that the configuration path is wrong before login,

save_config_file_path = os.path.expanduser("~") + "/.irConfig.yaml"

expanduser("~") in command.py gives a wrong path in this case.

Thanks!

Who to reproduce
Try installing the AUR package

Additional info

• Distro: Arch Linux
• Version: -
• Version of linux-enable-ir-emitter: latest
• How did you install linux-enable-ir-emitter: AUR

The PKGBUILD file is trying to pull source from the 2.0.1 tag, but it doesn't exist.

I followed the instructions to get the right parameters for a new laptop (VM + Wireshark) and found a set of parameters that work with enable-ir-emitter (i.e., that do not give any error) on my new Lenovo X1 Carbon, Gen. 9.
.
However, the IR emitters still do not work, even after running './enable-ir-emitter' or 'sudo ./enable-ir-emitter'
I also tried setting the 'frame_width = 340' and 'frame_height = 340' in the howdy config file, but I suspect the IR camera forces the values back to 640x360.

The confic values I found are:

• data: 0xff 0x00 0x00 0x00 0x00 0x00 0x00 0x00
  unit: '0x0a'
  selector: '0x0a'

I used the following command to try to configure the service: sudo linux-enable-ir-emitter -v -d /dev/video0 configure
I get the following message when I am done configuring:

INFO: The driver has been successfully generated.
ERROR: Error with the systemd boot service.

When I check the logs in journalctl, I saw the following:

linux-enable-ir-emitter[10416]: CRITICAL: The device /dev/video2 does not exists.
linux-enable-ir-emitter[10416]: INFO: Please choose among this list: /dev/video1 /dev/video0

It seems like it's not using the video0 device specified with the configure command.

Hello, I dual boot Windows and Arch linux and I was trying to make the camera work with howdy on Arch, but after installing linux-enable-ir-emitter I tried to configure it and after several times it trying to configure the camera looping on both the infrared and the regular camera, it stopped working to open the camera device.

After rebooting on Windows now Windows can't access the camera as well. It says it can't use Windows Hello.

Running linux-enable-ir-emitter again now always times out on select for /dev/video0 and even the basic test of capturing data with gst-launch now returns an Internal data stream error.

Is there anything that happens during the emitter setup that can change the camera behaviour? Is there any way that I can restore it?

I've tried uninstalling and reinstalling the camera on Windows too hoping it would come back to defaults, but so far nothing helped.

Compilation fails because of missing dependency opencv2

After installing from AUR on Manjaro (yay -S linux-enable-ir-emitter) or via installer (# ./installer install), compilation fails with the error:

• driver-generator.cpp:23:10: fatal error: opencv2/videoio.hpp: No such file or directory

I also tried to install opencv2 manually via AUR. However that fails as well due to the following error:

• parallel.cpp:104:14: fatal error: tbb/tbb_stddef.h: No such file or directory

This is weird because this is actually a closed issue on official OpenCV repository (link).

Possibly related to Issue #71
Until V4 it was working without any issues but after updating to V4 the program broke. I have tried reinstalling it several times both from the AUR and directly from github and it fails the same way every time. Installing V3 from git creates a functioning configuration but upgradig to V4.1.2 and running the script to migrate the config breaks the program and subsequent attempts to reconfigure the program fails.

I have a Dell XPS 9310 2in1. Everything works fine except service script.

I get this at startup

"enable-ir-emitter[355]: Unable to open a file descriptor for /dev/video2"

I think launch script run before video drivers. How can we fix?

I updated today to 3.2 in Fedora 34, after the update it stopped working, I had to remove it and install again

alerque - https://aur.archlinux.org/pkgbase/linux-enable-ir-emitter/
This packaging in goofed up. It using a repository with no fixed version as it's source, and yet it doesn't have a pkgver() function. If it did it would be a VCS package, but that already exists elsewhere. This should be changed to only package tagged stable releases and use fixed source packages (whether tarballs or source builds are git archives, they need to be fixed with a checksum or specific SHA).

@komex, do you know how to handle it to comply with the guidelines ?

I will also try to contact the maintainer of the "-git" package to update it (#28 @FabioLolix).

If you had 'ERROR: Impossible to reset the control' message, give the DEBUG info displayed

Hi,

First of all a big thanks for creating this fix, I've got a Dell XPS 9510 and this fix works like a charm - until I restart the computer. After the restart it only starts to work again once I've run linux-enable-ir-emitter configure. Simply restarting the service doesn't work. I'm running Pop OS 21.04.

It also doesn't work after suspending the computer. After doing that the configure fails as well, at which point I need to restart the computer, log in, and run the configuration one more time to get it to work.

Any ideas what might cause this?

Kind regards,
Joakim

After uninstalling the earlier version, updating and reinstalling the latest version, the command doesn't start at all with any argument:

Since upgrading to V4 the infrared emitter on my Lenovo Yoga Slim 7 14ARE05 no longer works.

Additional info

• Version of linux-enable-ir-emitter: v4
• How did you install linux-enable-ir-emitter: AUR

As requested by @dav-is, version 3.2.0 supports the configuration of multiple infrared emitters.

To do this, simply run linux-enable-ir-emitter configure -d /dev/deviceX several times and change the desired camera each time.

The version is present on the dev branch to be tested.
In order to install it you need to run the bash script: sudo bash installer.sh install (remove the installed version first).

This guide worked perfectly, so thank you!

I have one issue left, though: on boot, the service fails to start with the message
Unable to open a file descriptor for /dev/video2.
I guess this is due to enable-ir-emitter.service starting before the webcam is properly detected by the system. I am unsure how to keep the service from starting, until the webcam is detected, as my technical knowledge of systemd is fairly limited. I tried adding after=systemd-udev-settle.service, but this did not solve the issue.
Interestingly, the IR-Blaster sometimes still works fine after a reboot when logging in in sddm, but not reliably.

Hi,

I'm trying to do something a bit different from what this project does, namely to make the IR emitter of my IR camera always be on when the camera is on.

I have a Chicony integrated camera which I'm trying to use to monitor a room at night. At the moment, when I turn on the IR camera, the emitter flashes; this would be the correct behavior for facial recognition but of course for a continuous video stream, it makes the video flash too.

I understand this is not the main purpose of this project but if you could tell me how to tweak it to achieve this or had any insights, that would be super helpful.

Here are some tech infos:
