OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

#!/bin/sh
# This script takes a photo if the computer has not been idle for longer than a period of time
# it uses isightcapture from https://www.macupdate.com/app/mac/18598/isightcapture

[ -z "$USER" ] && echo "missing variable \$USER " && exit 1
if [ ! -d /Users/$USER/daily_photo ]; then
    mkdir -p $/Users/$USER/daily_photo
fi
IDLE=$((`/usr/sbin/ioreg -c IOHIDSystem | sed -e '/HIDIdleTime/!{ d' -e 't' -e '}' -e 's/.* = //g' -e 'q'` / 1000000000 ))
export SUDO_ASKPASS=/Users/$USER/bin/get_pass.sh

The Basics

Every stream has two basic parts

• data-in - A chunk or EOF enters the stream
• data-out - A chunk or EOF leaves the stream

I'm combining both "data" and "end" events since "end" is just a special data packet signifying the end of the stream.

Flow Control

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
