Scrtipt breaks on MacOS building rav1e (solution inside)

[NicolasReibnitz]

Hey! Just some info for others who might face this. Compiler errors aren't my strong suit, so this threw me off. 😄

I ran the script on MacOS using ./build-ffmpeg --build --enable-gpl-and-non-free and it broke at some point giving the error message below.

Fix: you have to manually install cargo as mentioned in the docs. Follow the instructions here.
(I assumed it would simply skip including rav1e instead of breaking).

I did it by running curl https://sh.rustup.rs -sSf | sh and selecting the default option (1) in the terminal.

After that the script ran fine and the binaries were successfully built!

Thanks Markus!
