Hi Zhong / Mark / Softworkz,

Is there any comment to this new patchset version? This version should not have
any impact to current user if --enable-libmfx option is used. We added --enable-
onevpl option for oneVPL usage but the suffix 'qsv' is still used in codec and
filter, so user needn't change their app or command if they don't use the
obsolete features.

Thanks
Haihao
