[Libva] [PATCH libva-intel-driver 11/18] Encoding: Dynamically select one mechanism to construct encoding command buffer for each frame on Gen7/Gen6

[Zhao, Yakui]

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

Currently it uses the fixed policy to construct encoding command buffer.
(Use CPU or GPU). And it is statically compiled.
But sometimes it needs to choose the different mechanism on the fly instead
of statically compiled mode.
