pip3 install and cargo issues

[bernid]

Hello,
Thank you for this script.
I'm trying to build ffmpeg with '--enable-gpl-and-non-free' on my Ubuntu 23.10 x64 machine.
Unfortunately I got stuck 2 times.
First time I've received:
'error: externally-managed-environment'
when script run:
$ pip3 install pip setuptools --quiet --upgrade --no-cache-dir --disable-pip-version-check
So I 've installed python3-venv, created a new virtual environment 'python3 -m venv myenv' and activated the virtual environment 'source myenv/bin/activate'.
The script moved on but stops building cargo and errors again appear indicating 'undefined reference to ...' some functions/files
See full script log:

What should I do move forward?

rav1e is so sloow, I recommend you to disable it with env var SKIPRAV1E
if you want to use av1 codec - use svtav1

Thanks for leading me to a temporary solution to sacrifice the rarely used librav1e AV1 encoder. I simply uninstalled rust/cargo
rustup self uninstall
and the building script continued to the end.
