"Scotch Box is a preconfigured Vagrant Box with a full array of LAMP Stack features to get you up and running with Vagrant in no time."

But it doesn't come with ffmpeg. While working small project taking the sound from one video and "pasting" it onto a video that just shows the presenting monitor,
stack overflow said
to do this:

ffmpeg -i presentation_monitor_no_sound.mp4 -i room_video_and_audio.mp4 -c copy -map 0:0 -map 1:1 -shortest output.mp4

and it worked great!

Scotch Box comes with a lot of great stuff, but no ffmpeg. Since Scotch Box is running Ubuntu 14.04 LTS (Trusty Tahr).
It took a few minutes to install ffmpeg. Here's a note to my future self on google helped me discover how to do it.

  1. apt-get install ffmpeg
    1. this failed.
  2. cat /etc/issue
    1. this shows that it's Ubuntu 14.04. This allowed for googling that pointed to:
  3. add-apt-repository ppa:mc3man/trusty-media
  4. apt-get update
  5. echo $?
  6. apt-get install ffmpeg
    1. Things worked this time :-)
