Then execute sudo linux-enable-ir-emitter boot enable. This should make your emitter working.

However, could you help me in debugging the error you had?

Could you retry with the command linux-enable-ir-emitter -v configure -d /dev/video2?

fervidnerd commented 7 months ago

Could you retry with the command linux-enable-ir-emitter -v configure -d /dev/video2?

Unfortunately I get the same error as above, even with the suggested changes.

EmixamPP commented 7 months ago

But after changing the content of the configuration file and executing the boot command, is your emitter is working now? You can execute linux-enable-ir-emitter -d /dev/video2 test to test it.

elegos commented 6 months ago

Hello there!

Same issue, same cam D:

I was previously prompted by you @EmixamPP to use the very same config file, but I can confirm that the error does not go away:

❯ sudo linux-enable-ir-emitter -v -d /dev/video2 configure
DEBUG: Executing configure command.
INFO: Stand in front of and close to the camera and make sure the room is well lit.

[1]    24758 IOT instruction  sudo linux-enable-ir-emitter -v -d /dev/video2 configure

The behavior is strange though: when you first try the face recognition, it won't blink and fail (image too dark). When you try to configure the device, even if failing, the next time you try to authenticate, it will blink and work, until the next restart.

EmixamPP commented 6 months ago

Can someone run gdb? Since I cannot reproduce, I need help to find which line raises the error

  1. Download and place in /usr/local/bin that the file inside the zip : linux-enable-ir-emitter.zip
  2. Execute the tool inside gdb : gdb -ex run --args linux-enable-ir-emitter -v configure
  3. When it fails, write inside gdb: backtrace
  4. Paste all the outputs in a comment

Ok very good, thank you! I will be able to find a fix.

To avoid that issue, you can add the --manual option.

EmixamPP commented 6 months ago

Otherwise, in the PR #176 you can find a bot comment with a link to a tarball and installation instructions that should fix the issue.
