Hi Andy,

Does svt-av1 imply the use of AVX2?
Maxim has observed some breakage in [1] with the use of svt-hevc.

It seems not an issue, reading
<https://gitlab.com/AOMediaCodec/SVT-AV1/-/merge_requests/1917/diffs>.
If there's no AVX2 support, SSE2 will be used, which will be slower but
backward compatible with all x86_64 CPUs made after the year 2000 :-).
