Per [1] That would be 39MB (uncompressed; probably about half that compressed) to include ffmpeg-darwin-arm64, since OS X doesn't ship with ffmpeg installed.

Screen recorder in under 100 bytes:

Open QuickTime and hit Command-Shift-N. Press record.

Screen recorder in 0 bytes: open camera app on phone and hit record.

Last time I checked, statically built ffmpeg was 100 MB, at least on Linux.

18.4MB compressed[1].

FWIW the transitive dependencies of the nixOS ffmpeg add up to 764MB, but dynamically linking is always much larger than statically linking, and that calculation will include more than just the shared-libraries.

Also note that he app includes an ffmpeg that is 39MB uncompressed.

you're not their target audience

does that work on MacOS?

Yes, but command is different: https://trac.ffmpeg.org/wiki/Capture/Desktop

No, but cmd+shift+5 does.
