Is this available for hevc ？
As
https://spec.oneapi.com/versions/latest/elements/oneVPL/source/appendix/VPL_apnds_f.html,
"The application can configure an AVC encoder to work in CQP rate
control mode with HRD model parameters. oneVPL will place HRD
information to SPS/VUI and choose the appropriate profile/level"
Looks like only available for AVC?
