Additional notes based on my own experience
EFI boot
Ubuntu 19.04 -> 21.04
This should work on any computer. Only the RAID > AHCI change described below and the device name for the nvme ssd drive are specific to this laptop.
The process describes a completely fresh installation with complete repartitioning, however it should work fine when Windows is already installed (eg. brand new machine with Windows preinstalled) as long as Windows already boots with EFI.
The process was conducted on Dell's XPS 15 9560 (2017) with specs:
CPU: i7-7700HQ

How to make a Raspberry Pi an RTSP streamer and how to consume this?

You should perform the following steps on a new SD card. Don't mess with existing solutions. It is not worth the $5 to loose something working.

I'm used to use Raspbian, so my suggestion is to go to https://www.raspberrypi.org/downloads/raspbian/ and download the latest Raspbian Stretch Lite. Flash it to your SD card. Mine have usually 16 GB, but maybe smaller work too. I'm using Etcher on macOS, a great tool for flashing.

After successful flashing enable ssh and prepare a running Wifi configuration.

A Wifi adapter should be attached to your Pi of course.
