Trying to run the simple grab code gives me the following error:

Thanks, but now it says the camera is not connected.

Actually you can run the command the script does (system_profiler SPCameraDataType)

Maybe the device isn’t enumerating as a camera?

(not relevant but there is a version of lsusb in homebrew btw)

OK I ran system_profiler SPCameraDataType. Seems to enumerate as a camera (and the GroupGets GetThermal app recognizes it just fine)

Camera:

    PureThermal (fw:v1.3.0) #3:

      Model ID: UVC Camera VendorID_7758 ProductID_256
      Unique ID: 0x142140001e4e0100

    FaceTime HD Camera (Built-in):

      Model ID: UVC Camera VendorID_1452 ProductID_34068
      Unique ID: 0x8020000005ac8514

This is a bit odd. The output from system profiler before looks fine (these are the numbers we check for):

Product ID: 0x0100
Vendor ID: 0x1e4e  (Etron Technology, Inc.)

But here you have a different PID/VID:

UVC Camera VendorID_7758 ProductID_256

I guess we ought to check for both, but I'm not sure why it's enumerating as different things. For now, you can go to lepton.py and replace the numbers with those above, but it would be good to figure out why there is a discrepancy here.

You can also use lepton.setup_video(device_id) where device_id is probably 0 or 1. It won't necessarily be robust (sometimes your webcam can switch ID), but if you just want to check your camera, you can set that up manually instead of having flirpy try to find your device automatically.

Well 7758 is the hex to decimal translation of 0x1e4e. I guess Apple converts it for some reason?

Anyways, I made the changes you suggested but it still didn't work. I get the following errors now:

using camera.setup_video(1):

[ERROR:0] global /private/var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T/pip-req-build-tetsazc6/opencv/modules/videoio/src/cap.cpp (291) open VIDEOIO(AVFOUNDATION): raised unknown C++ exception!

    raise IOError("Failed to open capture device {}".format(device_id))
OSError: Failed to open capture device 1

with only the changes to lepton.py:

Traceback (most recent call last):
  File "capture_test.py", line 26, in <module>
    image = camera.grab()
  File "/Users/ccastellanos/opt/anaconda3/envs/artibmcp-thermal/lib/python3.7/site-packages/flirpy/camera/lepton.py", line 166, in grab

    res = struct.unpack("<2cII16x4h6xIh2xh8xhI4xhhhhhh64xI172x", image[-2,:])

and the builtin-in webcam turns on briefly

Odd well I guess on the macbook I initially used for this it was in hex to begin with. I don't own a PT2 so I can't verify on my newer M1 unfortunately. Easy to fix though, we'll just check for both 🤷‍♂️

If your webcam is blinking then you're probably using the wrong device ID. Did you try 0?

@carloscastellanos

Yes I tried 0 as well. I'm beginning to think this may be an issue with my Macbook. I'm going to try this on another Mac and see what happens

Can you try with OpenCV directly?

import cv2
devid = 0 # or 1
cap = cv2.VideoCapture(devid)
image = cap.read()
print(image)

Flirpy just creates a VideoCapture object. The GroupGets library (I think?) uses, or at least used to use, a custom UVC driver so they got around limitations with AVFoundation.

@carloscastellanos

Yes I tried OpenCV as well and that also is not working! I'm getting "an unknown C++ exception".

I've tried installing the groupgets version of libuvc (thinking that might be the issue) but that fails too when I try to run cmake. So not a good for me, lol.

That's actually my original plan. Capture with OpenCV and use flirpy for analysis.

I've also posted on the groupgets googlegroup, so I'm still hopeful I can this working.

@carloscastellanos

UPDATE: I think I may have figured it out. If run as sudo, this file works: https://github.com/groupgets/purethermal1-uvc-capture/blob/master/python/uvc-radiometry.py

This grabs a stream directly from libuvc. So it seems that at least for now libuvc is the way to go on pure-thermal 2 on MacOS for grabbing a video stream

@jveitchmichaelis

Yeah it's possible we could bundle libuvc with flirpy and have it load on Mac somehow. I'll see if I can get hold of a PT2 board to test on my laptop, but for now I'd suggest just using the groupgets library.

Closing as this seems to be a somewhat-isolated issue, until we can definitively fix it here there is a solution in the other library.
