[FFmpeg-user] A query on slice based encoding in vp9_vaapi

According to the VAAPI encoder docs, slice based encoding can be enabled
for the respective encoders via the -slices:v n where n is the number of
slices so desired.
However, toggling this option on for the vp9_vaapi encoder results in a
warning on initialization about slice based encoding not being supported,
but the encoder runs nonetheless to completion.
I’ll post the console output (and ffmpeg build version ) when I’m at the
desk, but the question remains: Is there a specific reason as to why slice
based encoding is disabled (or not implemented) in this encoder?
This query is a redirect from this issue on the intel vaapi driver project
https://github.com/intel/intel-vaapi-driver/issues/452 as they may be
related. If this isn’t the right place to ask this question, let me know.
