Enable systemd in WSL 2

NOTE: If you have Windows 11 there is now an official way to do this in WSL 2, use it if possible - see MS post here (WINDOWS 11 ONLY)

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

• To enable systemd under WSL we require a tool called systemd-genie

• Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:

DASH Live Streaming

There are multiple technologies involved in live streaming using DASH (DASH stands for Dynamic Adaptive Streaming over HTTP).

1. MSE (Media Source Extensions): this is the browser part that allows us to create an sliding window buffer from chunks of video. There are a lot of libraries that handle this part for us, for example: dash.js or Shaka Player.
2. ISO BMFF (usually known just as MPEG4), Matroska, x264, x265, vp8, vp9, Vorbis y Opus: All of these codecs can be used to encode/decode the video into chunks (but there are some incompatibilities between browsers). There are a lot of tools that allows us to create these chunks using these codecs: ffmpeg, gstreamer, dashencoder, Shaka Packager, DashCast, MP4Box, etc.
3. MPD (Media Presentation Document): this part belongs to DASH and allows us to define how the chunks are, what they contain and how they can be consumed depending on network bandwidth, language or screen properties.
