hello @hamoid! im trying to use your librarie in Eclipse… but the console show me this error:

```auto

```

i can import the librarie correctly, but the error is in the line that i create the videoExport obj:

`videoExport = new VideoExport(this);`

im doing something wrong? i put the ffmpeg file into the folder also. its the basic sketch example, but in eclipse

This should help: [https://github.com/kfrajer/ProcessingVideoInEclipse](https://github.com/kfrajer/ProcessingVideoInEclipse)

I don’t think you need to add ffmpeg to eclipse. You just need to make sure it is in your PATH variable. If you open a command prompt and type `echo %PATH%`, the path of the ffmpeg executable should be there in that output.

Hi! Which OS, version, Processing version and Java version are you using?

I’ll check out the code. Strange that it tries to access `com/sun/jna/platform/win32/Wincon` if you are on Mac.

Could you please share your Main.java code? I tried in the Processing IDE in Mac and in IntelliJ Idea in Linux and it worked fine.

@hamoid

Hi everyone! I have the same issue in IntelliJ IDEA.

Tryed to get it run for a few hours but it still does not work.

If you wanna try the whole app:

> **[timrodenbroeker/my\_life\_as\_a\_timeline](https://github.com/timrodenbroeker/my_life_as_a_timeline)**
>
> An experimental data visualization in Processing, built with IntelliJ IDEA - timrodenbroeker/my\_life\_as\_a\_timeline

This is my error code:

```auto

Solved!

I’ve just added all the jars from the library folder to my project. Now it works fine! Thanks @hamoid for the brilliant library! 🙂
