带有 frei0r 库的 ffmpeg 在 os x 10.14.6 上失败
ffmpeg with frei0r libraries fails on os x 10.14.6
我在 Mac OS X 10.14.6 (Mojave) 上，使用自制软件安装 ffmpeg 和 frei0r。
如果您检查下面的输出，选项 --enable-frei0r 就在那里。
我验证了 frei0r 库的路径并像这样调用 ffmpeg：
FREI0R_PATH=/usr/local/Cellar/frei0r/1.6.1/lib/frei0r-1/ ffmpeg -v debug -i running.mkv -filter:v frei0r=pixeliz0r=0.02:0.02 pixel.mkv
但是它失败的方式与我没有通过 env var FREI0R_PATH:
