ffmpeg.js Heap memory error

Hi, I have some issues using your package with react-scripts start. At the moment of starting my project the amount of memory used skyrocket to at least 30% in a 16GB computer. I try running again with --max_old_space_size=15000 and same result.

I work with nvm and tried with node 15.8.0 and 14.15.4 (LTS). Library version is 4.2.9003
