Useful Examples of ffmpeg and GNU parallel on the command-line:

Transcoding FLAC music to Opus:

ffmpeg is a highly useful application for converting music and videos. However, audio transcoding is limited to a a single core. If you have a large FLAC archive and you wanted to compress it into the efficient Opus codec, it would take forever with the fastest processor to complete, unless you were to take advantage of all cores in your CPU.

parallel 'ffmpeg -v 0 -i "{}" -c:a libopus -b:a 128k "{.}.opus"' ::: $(find -type f -name '*.flac')

Transcoding Videos to VP9:

	</head>
	<body>
	<form id="uploaderForm">
	<label for="uploaderForm">Upload multiple Files</label>
	<div>
	<input type="text" name="applicantName" id="applicantName"

	#!/bin/bash

	# SETUP
	# 1) This requires having SoX (http://sox.sourceforge.net/) installed. On a Mac, you can do this with `brew install sox --with-flac`
	# 2) You'll also need an API key for your Google Cloud Platform project: https://support.google.com/cloud/answer/6158862

	# Create a request file with our JSON request in the current directory
	FILENAME="request-"`date +"%s".json`
	cat <<EOF > $FILENAME
