Error configuring systemd service when using custom video custom #78

Closed CharlesNRU closed 2 years ago

CharlesNRU commented 2 years ago

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.

Do you see other files than video0 in /etc/linux-enable-ir-emitter/ ?

If a file video2 is in the dir, execute sudo linux-enable-ir-emitter -d /dev/video2 delete and then sudo linux-enable-ir-emitter boot enable. I think this should solve the issue.

Otherwise, can you provide the output of linux-enable-ir-emitter boot status and cat /usr/lib/systemd/system/linux-enable-ir-emitter.service

There is no other file than video0 in /etc/linux-enable-ir-emitter/

Please execute linux-enable-ir-emitter -d /dev/video0 boot enable, it should work

Hi sorry for the late reply, I get the same error message: ERROR: Error with the systemd boot service.

The output of journalctl -u linux-enable-ir-emitter.service is the following:

systemd[1]: Starting linux-enable-ir-emitter.service - enable the infrared emitter...
linux-enable-ir-emitter[28624]: CRITICAL: The device /dev/video2 does not exists.

I've committed a fix. But I don't know when I'll have time to update all the distro repositories.

So either you use the bash script to reinstall the software. Or you can change the contents of /usr/bin/linux-enable-ir-emitter with https://raw.githubusercontent.com/EmixamPP/linux-enable-ir-emitter/master/sources/linux-enable-ir-emitter.py

Hello, I just tried the new version and it works correctly! Thank you for the quick fix.

The 4.1.5 is published on every distro repo
