Media Utility Scripts

Bash scripts for common conversion tasks on multimedia (video, image, audio) files. I've put these scripts together so I don't have to look up common conversion parameters all the time. Built to work on OS X.

Prerequisites

These scripts depend on the following libraries, which can be easily installed with apt or Homebrew:

• ffmpeg
• imagemagick
• pngquant
• jpegoptim
• optipng
• gifsicle
• LAME
• SoX
• ImageAlpha

Setup

Make sure these scripts have appropriate permissions:

chmod 755 *

Using the scripts

In your shell, just put a ./ in front of the script name then provide parameters described in the script file. For example, using movie2gif.sh looks like this:

./videoToGif.sh /Path/to/movie/file.mov 600

Windows Setup

• Get Ubuntu installed from the Windows Store. This requires enabling Windows Subsystem for Linux (WSL) from Turn Windows Features on/off in Control Panel
• Open the Ubuntu app installed from the Store or CMD + R and type wsl
• Install Linuxbrew:
  • sh -c "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install.sh)"
  • PATH="/home/linuxbrew/.linuxbrew/bin:$PATH"
• Install libraries:
  • brew install imagemagick
  • brew install ffmpeg
  • brew install gifsicle
  • brew install LAME
  • brew install SoX
  • brew install dos2unix
• Convert dos carriage returns to UNIX format with dos2unix
• Find your C: drive and path to the scripts:
  • cd /mnt/c/files/media-utility-scripts
