[Libva] [PATCH V3: 04/11] Encoding: Pass the qp parameter into VME shader and VME shader select the different cost table based on input Qp on Ivy

Thu Aug 11 03:00:07 UTC 2016


From: Zhao Yakui <yakui.zhao at intel.com>

v1: add assert after bo map

In order to suppor that macroblocks have the different QP to do the motion
prediction, different cost tables are provided so that the VME engine can
select the different mode/motion-vector cost tables based on the input Qp.
