AMD VA-API encoding latency

As of this writing (2024-05), VA-API has no support for AMD's low-latency encoding mode. This is problematic for ultra low-latency applications like realtime game-streaming as implemented by Sunshine.

As a temporary fix, Mesa can be patched to unconditionally use the low-latency optimizations. This entails a higher power consumption and may not be suitable for all applications.

Patching Mesa for Ubuntu

I'm providing a basic shell script to re-build Ubuntu's Mesa from the official source .debs with the necessary patch. It has only seen some light testing (22.04 only) and is provided without support. For my own usage I'm executing this script in a throw-away Incus container based on Ubuntu 22.04. The script does not clean up after itself (i.e. no purging of build dependencies etc.). **Make sure to valid

Building and using mesa for development and testing

This explains how to build mesa from source, and how to use the custom built mesa to run some apps and games, without needing to replace the mesa libraries that your operating system runs on.

Let's assume that you are using an x86_64 system.
