Jython internals might be in a bad state now that can cause deadlocks later on.

Hi @huxx,

Welcome to the forum! 😉

I don’t have a solution for your particular issue but you might want to check those previous threads:

- [How to display video in PythonMode?](https://discourse.processing.org/t/how-to-display-video-in-pythonmode/485)
- [SVG library doesn't work in Python mode?](https://discourse.processing.org/t/svg-library-doesnt-work-in-python-mode/10270)
- [Can't load library](https://discourse.processing.org/t/cant-load-library/23466)

(On Linux and Processing 3 importing the video library works correctly)

Has the problem been solved yet? I got a similar problem while using the add\_library(‘video’), but my error message is

UnsatisfiedLinkError: C:\Users\user\Documents\Porcessing\libraries\video\library\windows64\avcodec-58.dll: Can’t find dependent libraries …
