Give more information if you have The camera and IR LEDs work in GNOME Snapshot and flicker when I run the configure command, but it still returns "Impossible to find an infrared camera". It also returns "Unable to obtain the /dev/videoX path" when I specify /dev/video0 as the camera

Additional info

• Computer (or camera) model: ThinkPad X1 Yoga 3rd gen
• Linux distribution: ArcoLinux
• Version of linux-enable-ir-emitter: 5.2.4

If your IR emitters are working, for what purpose you want to use this tool?

It also returns "Unable to obtain the /dev/videoX path" when I specify /dev/video0 as the camera

Please try the v6 #154, it fixes this error; there is a bot comment in the PR that explains how to install it.

[ctrl-alt-breathe]

Because howdy only blinks the LEDs once then says no face found

[ctrl-alt-breathe]

I followed the uninstallation steps then installed that v6 version, but it still gives the videoX error

[EmixamPP]

Strange, I had the same problem as you because of usbv2 v4l paths, and the fix I added in the v6 solved the problem on my setup. Could you show me the outputs of:

linux-enable-ir-emitter test
linux-enable-ir-emitter -d /dev/video0 test
linux-enable-ir-emitter -d /dev/video2 test

Thanks!

[ctrl-alt-breathe]

All 3 of them show me: CRITICAL: Impossible to find an infrared camera.

[EmixamPP]

This seems very weird. I've updated the error message to get more information. Could you go in the PR and install the tool again? (please uninstall the previous first, by following the instruction on the master branch) Then, could you copy past the outputs of all these commands:

find -L /dev/v4l/by-path -samefile /dev/video0
linux-enable-ir-emitter -d  /dev/video0 test
linux-enable-ir-emitter -d  /dev/v4l/by-path/pci-0000:00:14.0-usb-0:5:1.0-video-index0 test
linux-enable-ir-emitter test

Please do not resume to what is shown, but really copy past to avoid confusion.

[EmixamPP]

You can try again if you want to, I've refactored the system of devices discovering.
