Why this program needs ffmpeg?

[epiciskandar]

I've installed btop through brew on my Macbook, noticed that ffmpeg and corresponding indirect dependencies introduced. Since btop is a terminal UI application, I can not understand why it depends on ffmpeg

It doesn't.

From https://formulae.brew.sh/formula/btop:

Depends on:

gcc	11.3.0	GNU compiler collection

Depends on:
gcc 11.3.0 GNU compiler collection

Depends on when building from source:
coreutils 9.1 GNU File, Shell, and Text utilities

Yes, you are right. I've rechecked dependency by brew deps --tree --installed btop, it doesn't have ffmpeg dep. And I've tried remove btop and all dependencies and reinstalled it, ffmpeg don't install this time.

I have scrcpy installed, which depends ffmpeg, might be some kind of homebrew mechanism triggered ffmpeg installing/upgrading during btop installation.
