Built libaom 3.8 just on my default laptop now after downloading from https://cloud.mail.ru/public/tFTC/PpkmydyYP and did 1 minor test with no problems.  Andrew, is    libaom-v3.4.0.patch1   equivalent for 3.8 no longer needed?

They reworked cpu detection so it does not apply anymore. Hopefully not needed, but for now I just trying to see if 3.6.1 can be compiled on old Ubuntu 16 without too much cmake hacking ...

=====

Release Notes:

2023-11-30 v3.8.0
This release includes new codec interfaces, compression efficiency and
perceptual improvements, speedup and memory optimizations and many bug
fixes. This release is ABI compatible with the last release. 


some reported speed gains are impressive:

Speedup and Memory Optimizations
* Good-quality, single-thread encoder speedups:
o 15% improvement for speed 5.
o 12% improvement for speed 6. 

but most of them for new Arm servers, it seems.

I'll try to see if I can repackage it here....
