FFmpeg Cheat Sheet for 360º video

Brought to you by Headjack

 
FFmpeg is one of the most powerful tools for video transcoding and manipulation, but it's fairly complex and confusing to use. That's why I decided to create this cheat sheet which shows some of the most often used commands.

 
Let's start with some basics:

• ffmpeg calls the FFmpeg application in the command line window, could also be the full path to the FFmpeg binary or .exe file

#!/bin/bash
# This script will take an animated GIF and delete every other frame
# Accepts two parameters: input file and output file
# Usage: ./<scriptfilename> input.gif output.gif

# Make a copy of the file
cp $1 $2
echo "copy completed"
# Get the number of frames
numframes=`gifsicle $1 -I | grep -P "\d+ images" --only-matching | grep -P "\d+" --only-matching`

gifsicle "$1" --unoptimize $(seq -f "#%g" 0 2 $numframes) -O2 -o "$2"
