non-square pixels?

xeve-main --verbose 2 --input stdin --input-depth 10 --input-csp 1 --fps 30000/1001 --codec-bit-depth 10 --rc-type 0 --qp 32 --profile baseline --level-idc 6.2 --range limited --colorprim unknown --transfer unknown --matrix-coefficients bt470bg --sar 8:9 --output "J:\tmp\2024-04-28@19_44_30_5310\alienson2001_new_1_2024-04-28@19_44_30_5310_02.evc"
fails with:

XEVE: eXtra-fast Essential Video Encoder
[D:\a\xeve\xeve\app\xeve_app.c:1035] vui parameters is not proper

but it works if I change --sar 8:9 to --sar 1:1.

=> would be nice if other aspect rations than 1:1 would be supported.
