IR not recognized about howdy HOT 8 CLOSED

I've seen some other laptops where the IR webcam is not implemented as a separate USB camera, but are combined into the same controller entirely. My suspicions are that they need to be controlled through /dev/media0, which is the controller of /dev/video0.

I don't know how though, i have very little experience with the media controller. If you find out how, please do share it here.

You can answer yes to the "is this the IR camera" question in the installer but i would not recommend it and it might break.

All right, so the face recognition still works. However, I guess I have even less experience with the media API of the Linux Kernel than you have, I've never touched it before. I'd not even know where to start implementing the IR emitters. Really disappointing...

I've looked into the mechanics of it all, but with my limited knowledge of C++ it's near impossible. If you really want to, this TI site helped me understand the system a lot better, but i can't even figure out where i'm supposed to import the header file from.

I've come across an option in the v4l2-ctl command that can list all available controls for that camera. Could you try running

ls /dev/ | grep video

and then running the following command for each video device it reports

v4l2-ctl -l -d /dev/videoX

There might be a related control option for IR in there somewhere.

Thanks for coming back to this issue @boltgolt
It's interesting to see what options the device offers. It seems like there's no IR option, however.

I simply guess there are two video devices: the IR one and the usual webcam. Both need an own driver. The webcam has a linux driver whereas the IR cam doesn't have one. Disappointing...

Only video0 is visible. My ouput has the same parameters as that of @nico151999 .

from howdy.

I have the same issue here. I have some experience in C however, so I'm willing to give it a shot. I'll look at those links.
Output of v4l2-ctl is the same as above.

from howdy.

Same here. Face recognition works, though no IR emitters at all (works well in windows).
