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.

1. Read ID3 metadata

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

Serving multiple webapps from different folders

November 29, 2011 developmentNginx

Few days ago I had to add a wordpress installation within the same environment where a Codeigniter app was already running happily and undisturbed.

It took me a while to figure out how to keep separate folders on the filesystem, and serve the blog from a subfolder of the main domain:

h1z1

#!/usr/bin/env bash
# This script requires:
# - that the directory $HOME/.mpv exist 
# - that the program socat be installed
# - that you start mpv with the unix socket feature pointing at that directory
#   I recommend an alias in your .bashrc or equivalent file:
#       alias mpv="mpv --input-unix-socket=$HOME/.mpv/socket"

socket="$HOME/.mpv/socket"

Generating Authy passwords on other authenticators

---

There is an increasing count of applications which use Authy for two-factor authentication. However many users who aren't using Authy, have their own authenticator setup up already and do not wish to use two applications for generating passwords.

Since I use 1Password for all of my password storing/generating needs, I was looking for a solution to use Authy passwords on that. I couldn't find any completely working solutions, however I stumbled upon a gist by Brian Hartvigsen. His post had a neat code with it to generate QR codes (beware, through Google) for you to use on your favorite authenticator.

His method is to extract the secret keys using Authy's Google Chrome app via Developer Tools. If this was not possible, I guess people would be reverse engineering the Android app or something like that. But when I tried that code, nothing appeared on the screen. My gues

Using VAAPI's hardware accelerated video encoding on Linux with Intel's hardware on FFmpeg and libav

Hello, brethren :-)

As it turns out, the current version of FFmpeg (version 3.1 released earlier today) and libav (master branch) supports full H.264 and HEVC encode in VAAPI on supported hardware that works reliably well to be termed "production-ready".
