I am attempting to use the [VideoExport library by hamoid](https://github.com/hamoid/video_export_processing) but am running into a compile exception with the error **ClassNotFoundException: com.hamoid.VideoExport**. This means even the example patch ‘basic’ from the library does not work.

I have installed this library via the Processing ‘add libraries’ browser and have ffmpeg installed on my machine. I have the file VideoExport.java in my path \Processing\libraries\VideoExport\src\com\hamoid, so perhaps this is an issue with Processing not correctly pointed to the right location? Any tips as to how I could resolve the problem would be appreciated, or pointers to other video export tools.

Running Windows 10.0.19045 Build 19045, and Processing 4.0b2

Hello,

It works here with Processing 3.5.4 on W10.

It gives me this error with Processing 4.3 on W10:

This is the version of ffpeg in my path:

> C:\Users\me\>ffmpeg  
> ffmpeg version 2023-11-22-git-0008e1c5d5-essentials\_build-www.gyan.dev Copyright (c) 2000-2023 the FFmpeg developers  
> built with gcc 12.2.0 (Rev10, Built by MSYS2 project

I had the same experience here:

I have not explored this further.
