Audi MMI Video convertor
This utility is made to convert any video file in to the correct size and format for Audi's 3G+ MMI dashboard system (designed for Q5 display, but should work on others). I used the information on this forum thread to try to get the right settings.
It includes the Progress bar from http://0xcc.net/ruby-progressbar/index.html.en and uses Open3 code for forking and progress from https://github.com/streamio/streamio-ffmpeg.
