Hello! Thank you for your work on this repo. I'm very keen to use it, however I'm struggling to make the IR LED on my laptop work, I get stuck at the configuration stage sadly. I hope I've provided all the information needed - if there's anything I can do to help or experiment with please let me know and I will respond promptly. Thank you :)

Additional info

Attempted with multiple kernel versions. Currently using: Linux 6.1.7-060107-generic x86_64. Same output for all cases.

Laptop is a Dell Latitude 7280. IR LED was checked with a camera tested and known to show IR LED light. linux-enable-ir-emitter when tested on /dev/video0 caused the visible white indicator LED to flash, but when repeated for the IR camera, the IR LED never lit (using /dev/video2).

Tested all devices in /dev/videoX (and even /dev/mediaX out of blind hope). /dev/video2 is the only case where there is an IR camera which opens with ffplay.

Followed all wiki instructions - even disconnecting the battery for 1 minute and attempting again.

Hello, I'm currently quite busy, but I will look into it in two weeks! (I think I have an idea for a fix)

EmixamPP commented 1 year ago

You can test it on the dev branch, you have to install the OpenCV C++ libraries (libopencv-dev package on Ubuntu distro based) in order to be able to build the software:

git clone https://github.com/EmixamPP/linux-enable-ir-emitter.git
cd linux-enable-ir-emitter
git checkout dev
sudo bash installer.sh install
sudo linux-enable-ir-emitter -v configure

The software will ask you to shut down and boot and retry at some point

I could not test as I cannot reproduce this problem; send me the outputs in case of issue

Don't hesitate to ask me any question if you need help

Hi! Thanks for finding some time to work on this. I did as you suggested, and I get the following log. (IR emitter did not light)

I've been trying to figure out how it works so I can have a try too when time permits.

EmixamPP commented 1 year ago

Um, it looks like your infrared camera doesn't give any information on how it can be configured.

Here we can observe that your camera indicates only one possible instruction. However, 4 times in a row it refused to apply a modification on the instruction; in order to find the right one, which enable the emitter.

May be try with this command: sudo linux-enable-ir-emitter -v configure -l 256 The option -l 256 will avoid the "Negative answer limit exceeded, skipping the pattern.", and perform a full exploration of the possibilities.

Otherwise, unfortunately, I don't think I can do anything about it.

WillMatthews commented 1 year ago

Whoops, thought I sent this comment earlier but I didn't. I tried again with -l 256 but unfortunately for the instructions it tried the LED didn't light.

EmixamPP commented 1 year ago

Hey, I'm coming back to you with a new version that might be able to configure your camera.

The installation method has changed, I no longer maintain the Ubuntu PPA, but a unique tarball. There is a comment from a bot in pull request #121, the installation instructions for this pre-version are specified in it. To configure your camera, run the command sudo linux-enable-ir-emitter -v -d /dev/video2 configure -m -x (and past the output here). And maybe also try with /dev/video0.

If you no longer wish to configure your infrared camera, no problem, please just close the issue.

WillMatthews commented 1 year ago

Hi, thanks for your work, I had no issues getting linux-enable-ir-emitter installed.

Unfortunately, I still couldn't get the IR emitter to flash or even turn on.

Here is the dump from my terminal

Thank you once again, when I have time I might try digging more but I'm stretched very thin at the moment. I'll be more than happy to test any future versions :)

While I'm here, is there an uninstaller?

EmixamPP commented 1 year ago

No uninstaller, but the readme contains the command to execute: 

sudo rm -rf /usr/lib64/linux-enable-ir-emitter \
/usr/libexec/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
EmixamPP commented 1 year ago

I've just finished the exhaustive search, please refer again to the pr for installation.

To configure your camera, run the command sudo linux-enable-ir-emitter -v configure -l -1. This runs a fully exhaustive automatic configuration. If the tool thinks it has detected that the transmitter is blinking, it will ask you to confirm. Please ensure the room is well lit.

This can be a long process, but, since all you have to do is confirm whether it works, you don't have to be in the terminal all the time. You can let it search on the side, and cross your fingers, because this time (unless there's a bug in this pre-version) the tool will try everything it can try. And as a result, I don't think I'll be able to make a future version that will activate your emitter.

EmixamPP commented 1 year ago

Maybe try first sudo linux-enable-ir-emitter -v configure -m (I did some modifications), because the exhaustive search is really going to take a long time

EmixamPP commented 1 year ago

I'm closing the issue, but if you still want to try configuring your camera, don't hesitate to leave a comment. I'll be happy to help you further.

WillMatthews commented 1 year ago

Thanks,I tried the exhaustive search but it ended up erroring out. I’m quite strapped for time at the moment so I might have another look in a few months.Many thanks again - sorry we didn’t get anywhere :'(

EmixamPP commented 10 months ago

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.
