AVFoundation not available

[rudemex]

Hi, run ffscreencast --test in my terminal, but return

[OK] Operating system supported: Darwin
[OK] ffmpeg found: /opt/local/bin/ffmpeg
[ERR] [OSX]: AVFoundation not available in ffmpeg.
- Desktop recording not possible.
- Sound recording not possible.
- Camera overlay not possible.

How do I enable AVFoundation?

Have MacOs Sierra v10.12.6

thanks!
