Installing ffmpeg on Amazon Linux 2

gistfile1.txt

In case helpful, this worked for me. 
I opted for prebuilt for speed and peace of mind - this should work on any architecture of Amazon Linux 2. 
(_Although not tested , should also work for Amazon Linux 2023_).

**Prereq** 
- visit https://johnvansickle.com/ffmpeg/ to grab the link to the relevant tarball for your specific server architecture.
- Use `uname -a` to find out your arch if unknown

### TL;DR
```shell
mkdir ~/sources && cd ~/sources
wget https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-arm64-static.tar.xz
tar -xvf ffmpeg-release-arm64-static.tar.xz
cd ffmpeg-*-arm64-static
sudo mv ffmpeg /usr/local/bin/
sudo mv ffprobe /usr/local/bin/

# confirm it's working
ffmpeg -version  
```

### The details - for those who need more info
```shell
# Create/use a temporary working directory
mkdir ~/sources && cd ~/sources

# Download tarball 
# => Visit https://johnvansickle.com/ffmpeg/ to see list of available builds per arch & distros
wget https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-arm64-static.tar.xz

# extract tarball
tar -xvf ffmpeg-release-arm64-static.tar.xz
cd ffmpeg-*-arm64-static

# *** you may want to test to confirm it works ***
./ffmpeg -version  # should see something like: `ffmpeg version 7.0.2-static` on first line

# relocate to system path
sudo mv ffmpeg /usr/local/bin/
sudo mv ffprobe /usr/local/bin/

# confirm it's working
ffmpeg -version   # => ffmpeg version 7.0.2-static

# cleanup - optional
cd ~/ && rm -rf ~/sources/ffmpeg-*
```

#### RE automated provisioning
This solution should work with automated provisioning as well or easy enough to adapt to specific needs. 
It uses the latest stable package at the endpoint and does not rely on knowing the strictly version specifically named folder of the extracted tarball i.e. `cd ffmpeg-*-arm64-static`.
