• Summary

Due to this issue with fluent-ffmpeg, it's impossible to package anything with Rollup that uses the puppeteer-screen-recorder library. fluent-ffmpeg anyway hasn't been updated in 7+ years, and using native ffmpeg commands with exec or similar would anyway be just as functional I would guess...
