Installation requirements fail

[JohnFF]

When setting this up on a raspberry pi model 3B I encountered numerous problems.

The first was the instructions provided for making the ffmpeg library. I found more recent instructions which worked with only some adjustments.

The second issue is the pip3 installing of the requirements. Something about needing a local env setting up?

When I attempted to install via apt python3-xyz most of the packages were already on the latest version but picamera could not be found.

The workaround I found was here: https://stackoverflow.com/questions/75608323/how-do-i-solve-error-externally-managed-environment-every-time-i-use-pip-3 and amounts to removing the restriction on managed environment.

Hi @JohnFF , Thanks for reporting!

I added the solution you provided to the readme here.

Do you perhaps also have a link to the ffmpeg installation instructions that you used?
