So, "Why Tape!?"

Or: "I thought tape was dead?"

Me too, before I started using it just recently, in the Year of our Lord, 2025, and absolutely fell in love with it

Consider the following:

#!/bin/bash
# usage: ./encode_hls.sh video.mp4 480
#
# Transcode to HLS @ XXXXp
#
# Simple little script I made, requires jq and ffmpeg
# I just use the ffmpeg from https://johnvansickle.com/ffmpeg/
#

export INPUTFILE=$1

# Background: this was done on a CentOS 6.5 ESXi VM running pmacct 1.5.0rc2 and PostgreSQL 9.3 from PGDG repo with 
# the following config line for pmacct:
#
# ./configure  --enable-pgsql --enable-geoip --enable-ipv6 --with-pgsql-libs=/usr/pgsql-9.3/lib --with-pgsql-includes=/usr/pgsql-9.3/include
#
#
# I also customized the table they used in postgres to add vertical partitioning, but that's another gist :)
