Created December 2, 2012 18:42
Read keypresses from user in terminal, including arrow keys using pure Ruby. This has since been folded into a much more robust gem called Remedy. https://rubygems.org/gems/remedy & https://github.com/acook/remedy
require 'io/console'
# Reads keypresses from the user including 2 and 3 escape character sequences.
def read_char
STDIN.echo = false
STDIN.raw!
input = STDIN.getc.chr
if input == "\e" then
input << STDIN.read_nonblock(3) rescue nil

Useful terminal control characters
# Terminal output control (http://www.termsys.demon.co.uk/vtansi.htm)
TC='\e['
CLR_LINE_START="${TC}1K"
CLR_LINE_END="${TC}K"
CLR_LINE="${TC}2K"
# Hope no terminal is greater than 1k columns

Ruby example of using Open3.popen3 with a select loop to read a child process's standard output and standard error streams.
#!/usr/bin/env ruby
require 'open3'
# Returns true if all files are EOF
#
def all_eof(files)
files.find { |f| !f.eof }.nil?

4chan’s guide to converting GIF to WebM - https://boards.4chan.org/g/res/41212767

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.
