当我在依赖项列表中注意到brew install ffmpeg libav时，今天我正在使用unbound安装FFmpeg和libav。
这很奇怪，因为unbound是DNS解析器，为什么ffmpeg需要它。
❯ brew install ffmpeg libav
==> Installing dependencies for ffmpeg: aom, frei0r, gmp, libtasn1, nettle, p11-kit, unbound, gnutls, lame, libass, libbluray, libsoxr, libvidstab, libvpx, opencore-amr, opus, libsndfile, libsamplerate, rubberband, sdl2, speex, giflib, leptonica, tesseract, theora, x264, x265 and xvid
我什至检查了ffmpeg的信息列表，但那里没有unbound
❯ brew info ffmpeg
