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

java.lang.RuntimeException: java.lang.NoClassDefFoundError: com/sun/jna/platform/win32/Wincon

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

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?

4

Java 8, El capitan, processing 3

5

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

Try, but still not working.

7

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.

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

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! :slight_smile:
