Answer 1

I responded on the GitHub ticket you filed.

According to:

apt-cache search libva

there is no libva1 anymore but you can edit the script to replace it with libva2. This is sufficient to build OMXPlayer on Raspbian Buster.

Other things can go wrong with the build and in the ticket you had some additional problems which I addressed there, but these aren't related to libva*.
