libsvt-vp9 fails to build in aarch64, seems like it tries to use x86 asm stuff:

[pyldin601]

Maybe use libvpx instead (or as a fallback?) 🤔
This has primarily been developed and optimized for x86-64 architectures.
Maybe there is a little sense in using this codec on arm64 systems?

@pyldin601 hey! yeap, after some digging in #301 i came to the same conclusion and maybe understabably intel do not seem to care about arm or generic c for libsvtp9 :) let's close this one.
