Installing ffmpeg with homebrew? I am trying to install ffmpeg and it's libraries with homebrew on a mac running osx (El Capitain). 
The installation completes however its seems only ffmpeg is installed and not ffprobe or drawtext.

I tried reinstalling with this command:

brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools


..but I get this

Warning:ffmpeg-3.0.2 already installed, it's just not linked


What am I missing? I have tried deleting and retrying the installation but the problem persists.
To answer this question, you need to link up ffmpeg, but I'd run some housecleaning too.

First remove ffmpeg from your system:

$ brew uninstall ffmpeg


Now update all your brew packages and references.

$ brew update
$ brew upgrade
$ brew cleanup


Now install ffmpeg on your system, and link it up:

$ brew install ffmpeg --force
$ brew link ffmpeg


Now you should be good to go.
