Get/set ID3 meta tags using ffmpeg

A quick guide on how to read/write/modify ID3 metadata tags for audio / media files using ffmpeg.

FFmpeg has a free-form command line option that allows the user to specify key-value-pairs for encoding metadata. Let's take a look.

To list all global metadata tags for a media file, just set an input but no output file.

cd icu && mkdir linux && cd linux

../source/runConfigureICU Linux --prefix=$PWD/prebuilts \
    CFLAGS="-Os"
    CXXFLAGS="--std=c++11" \

	<form action="" enctype="multipart/form-data" id="file-form" method="POST">
	<div id="upup">
	<h2>Upload update file</h2>
	<p id="progressdiv"><progress max="100" value="0" id="progress" style="display: none;"></progress></p>
	<input type="file" name="file-select" id="file-select">
	<button type="submit" id="upload-button">Upload</button>
	</div>
	</form>
	<script type="text/javascript">
	var form = document.getElementById('file-form');

	Ansible playbook to setup HTTPS using Let's encrypt on nginx.

	The Ansible playbook installs everything needed to serve static files from a nginx server over HTTPS.
	The server pass A rating on [SSL Labs](https://www.ssllabs.com/).

	To use:
	1. Install [Ansible](https://www.ansible.com/)
	2. Setup an Ubuntu 16.04 server accessible over ssh
	3. Create `/etc/ansible/hosts` according to template below and change example.com to your domain
	4. Copy the rest of the files to an empty directory (`playbook.yml` in the root of that folder and the rest in the `templates` subfolder)

	#1 Generate Public & Private Keypair

	#2 Create receipt.json - eg below - careful with line-endings, etc if line breaks

	#3 Create signature & Encode
	openssl dgst -binary -sha1 -sign private.pem receipt.json \| openssl base64 > signature.txt

	#4 Verify using OpenSSL & public key
	openssl base64 -d -in signature.txt -out signature.sha1 \| openssl dgst -sha1 -verify public.pem -signature signature.sha1 receipt.json
