[Libva] [Libva-intel-driver][PATCH 1/2] Encode/VP9: turn gen9_vp9_get_coded_status() into a local function

Xiang, Haihao haihao.xiang at intel.com
Mon Aug 15 02:46:10 UTC 2016


Set encoder_context->get_status to this local function when initializing,
so that we can fetch VP9 encoding status from the underlying context.

This patch changes the input parameters and removes redundant assigns
