TypeError: Argument 'value' must be double, not bool in line 61 (?)

[sunrise1873]

unfortunately it doesn't work under Debian stable.

command:

tc001v4.2.py --device 0

says:

Traceback (most recent call last):
File "/home/norman/Downloads/PyThermalCamera-main/src/tc001v4.2.py", line 61, in
cap.set(cv2.CAP_PROP_CONVERT_RGB, False)
TypeError: Argument 'value' must be double, not bool

What is wrong?

under Debian 12, line 61 need to be changed:

cap.set(cv2.CAP_PROP_CONVERT_RGB, 0)

This version 4.2 with the modification of line 61 works perfectly with an OS ubuntu desktop 23.04.
THANKS.

A Python program to read, parse and display thermal data from the Topdon TC001 Thermal camera!

Tested on Debian all features are working correctly
This will work on the Pi However a number of workarounds are implemented!
Seemingly there are bugs in the compiled version of cv2 that ships with the Pi!

Key Bindings:

a z: Increase/Decrease Blur
s x: Floating High and Low Temp Label Threshold
d c: Change Interpolated scale Note: This will not change the window size on the Pi
f v: Contrast
q w: Fullscreen Windowed (note going back to windowed does not seem to work on the Pi!)
r t: Record and Stop
p : Snapshot
m : Cycle through ColorMaps
h : Toggle HUD
QSocketNotifier: Can only be used with threads started with QThread
qt.qpa.wayland: Wayland does not support QWindow::requestActivate()

I can confirm this with SteamOS Linux 6.5.0-valve22-1-neptune-65

Hah! I'm trying to do the same thing with my Steam Deck.

Did you install python3-cv on the main system or did you use Distrobox (or similar)?

I'm using Distrobox (with a Debian base) but it fails with some errors:
qt.qpa.xcb: could not connect to display :0
