Hardware used: Orange Pi 4 LTS

OS: Armbian Jammy

Should work everywhere on Debian or Ubuntu

Step 1: Install build tools (meson, ninja)

Usually gstreamer uses newer version of meson then available in apt packages, so we need to also build and install it from source. This is super easy. Here I am using 1.2.3 version that is currently latest, but you can use any other version.

sudo apt install pip

Workarounds for building S on 8GB RAM environment:

1. At the start of the build:
[ 99% 138/139] /mnt/ssd/lineage/out/soong/.bootstrap/bin/soong_build /mnt/ssd/lineage/out/soong/build.ninja
This used to take around 30mins, after enabling zram now it takes around 30secs (thanks to @kdrag0n for the zram idea) which is on par with what happens in 16GB RAM building environments

sudo apt install zram-config for installing zram-config package
sudo nano /etc/fstab and add a # in front of the swap disk if you have one and then reboot
After booting cat /proc/swaps to check if zram is enabled or not
