[samohovets]

Needed for remotion-dev/remotion#6771

[JonnyBurger]

-> Downloaded the binaries and put them in remotion-dev/rust-ffmpeg-sys
-> Updated Cargo.toml in remotion-dev/rust-ffmpeg
-> Updated Cargo.toml in remotion-dev/remotion
-> Ran bun build.ts --all in packages/compositor

Unfortunately remotion-dev/remotion does not compile, whereas it did before:
