Hi, i can't seem to figure this out...

Basically i have a Mac, a patch with pix_video, and I have a camera connected - well it's a flir thermal camera connected to the PureThermal2 module (https://groupgets.com/manufacturers/getlab/products/purethermal-2-flir-lepton-smart-i-o-module).

The image from the camera displays perfectly as it should if i open skype (perfectly as you imagine thermal looks), on both mac and windows.
It also works in PD and looks as it should on a windows computer, through pix_video.
But on my Mac the image comes up green and purple, and with what i would describe as big scanlines but vertical throughout it.
Is it to do with pix_video? if it's a driver why does it appear perfectly on skype... if it's pix_video why does it work on my pc? I cannot figure this out... Unfortunately i cannot just adjust the colors and move on because the giant scanlines are there.

Any ideas would be very much appreciated!

THANKS!!

@cocobryce Because it is Apple they will only show it in green...... mac eh!....
Try a different pullover?
Seriously though. Have a look at the backend driver loaded (will /should be shown in the Pd terminal) for clues. You might be able to change it with a [driver something( message to [pix_video]
You should be able to print available drivers to the Pd terminal with just a [driver( message banged into the [pix_video] inlet.
pix_video-help.pd
Compare the list to the driver being used in windows, and if possible the one used in Skype on the mac.

@whale-av Thanks for the reply!

Thought i could figure this out, but not having any luck. I think you are right though, however i can't figure out how to see what driver to load, and then how i go about loading it... if i bang the driver examples from pix_video ( |driver 0(, |driver 1(, |driver dv( into the pix_video object i just get a "no method for 'driver'" message.

any insight?

@cocobryce Maybe a useful page.....
https://fr.flossmanuals.net/puredata/utiliser-une-camera-video/
but it is in French.....
It mentions....... http://webcam-osx.sourceforge.net/ for OSX webcam compatibility.

Also here....... https://github.com/groupgets/purethermal1-uvc-capture under ""uvc-radiometry. py"" looks very much like your problem.
