The application crashes while start detecting my hands in Gesture Recornizer

[projectnowhub]

Hi, I am new to Godot, when running the GDMP Demo, while running the Gesture Recognizer, the application crashes when it starts to recognize/detects my hands from Live Camera. I have attached the Errors below for your reference:

Hi, have you checked the timestamp_ms variable in GestureRecognizer.gd line 34 is actually monotonically increasing? The variable should be provided by Time.get_ticks_msec() of the engine, if it is not working as expected there might have bigger problems.

[projectnowhub]

func process_camera_frame(image: MediaPipeImage, timestamp_ms: int) -> void: print(timestamp_ms) task.recognize_async(image, timestamp_ms)

I printed the timestamp. And getting the following output: Godot Engine v4.2.2.stable.official.15073afe3 - https://godotengine.org OpenGL API 4.6 (Core Profile) Mesa 24.0.9-0ubuntu0.1 - Compatibility - Using Device: Intel - Mesa Intel(R) UHD Graphics 620 (KBL GT2)

Looks like the timestamp is working as expected, but I'm unable to reproduce your issue.

Can you check the following:

1. Have you modified the script in the demo?
2. Have you tried building the library from source?
3. Does using virtual webcam (e.g. v4l2loopback) for gesture recognizer have the same problem as using actual webcam?
4. Have you tried loading the video file to see if timestamp issue persist?

1) No. 2) No, Please let me know where i can find the documentation to build the library from source. 3) Yes, i have tried. 4) And it crashes for Videos and Image also.

Note: The face detector, Face landmarker and hand landmarker are working perfectly. But only in gesture recognizer, when it detects my hands then the application terminating.

Thanks for the feedback, it's strange that only specific task fails to run. I re-read your problem description, you mentioned the project crashed upon detecting the presence of hands. There should be some error messages outside the editor when the crash happen, you can try opening Godot editor in terminal, and see if relevant output appear after project crashed.

In the meantime, it'll be appreciated if you can provide the details of distro you are using, I would like to try if I can reproduce the crash.

The library build instruction can be found on source repository of GDMP https://github.com/j20001970/GDMP/blob/master/docs/BUILDING.md
