Hi,

Welcome to the forum!

Love the humor in this post! 😉

For your issue, are you sure that your video is located inside a `data` folder in your sketch folder?

I was thinking about problems with `.mov` format but are you sure that it doesn’t run with `.mp4` files?

I’ve already answered a topic on this here : [Cannot play the video after exporting the application](https://discourse.processing.org/t/cannot-play-the-video-after-exporting-the-application/25889)

Looks like some users have some issues with the library. You can try posting on this GitHub issue :
