# This is Geoloqi.com's Rainbows! config file. We are using this in production to run all our web apps.

# In my opinion, this is the best way to deploy a ruby web application. Unlike EventMachine based solutions,
# it uses real ruby threads, which allows it to take advantage of the internal non-blocking IO pattern 
# in MRI.
#
# Contrary to popular belief, MRI doesn't block execution to wait on IO when you are using threads, even
# with the GIL. The requests are done concurrently for anything that is based on the IO class. This 
# includes things like Net::HTTP and even `system commands`. Grep the MRI Ruby source code for

Grab ffmpeg from https://www.ffmpeg.org/download.html

It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.

The most trivial operation would be converting gifs:

ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm

• -crf values can go from 4 to 63. Lower values mean better quality.
• -b:v is the maximum allowed bitrate. Higher means better quality.
