Black Screen

[TheDaChicken]

Hey I tried this out and I am getting a black screen in the "output.webm" file but even tho I can see that FFmpeg is running and did not crash.

Code: https://pastebin.com/raw/4x8RRZMS
Node.js Version: v8.11.3
FFmpeg version: ffmpeg version N-86950-g1bef008 Copyright (c) 2000-2017 the FFmpeg developers
built with gcc 7.1.0 (GCC)
OS: Windows

Do you know how to fix this? I tried headless: false and headless: true.

Thanks.
