Enable hevc_vaapi vdenc: - media-driver require CTU size must be set as 64x64 at low power mode - cu_qp_delta_enabled_flag should be enabled for low power mode - low delay B to replace P frame - same ref_pic_list0/ref_pic_list1 Signed-off-by: Fu Linjie <linjie.fu@intel.com>

issue for ICQ mode support (ICQ will be set in ffmpeg vaapi by default): -qp should be set to test CQP mode. |
|
ICQ mode is not supported in low power mode, disabled on ffmpeg-level. |
ICQ mode is not supported in low power mode and should be disabled. For H264, Driver supports RC modes CQP, CBR, VBR, QVBR. For HEVC, Driver supports RC modes CQP, CBR, VBR, ICQ, QVBR. ICQ is not exposed while working on low power mode for h264_vaapi, but will trigger issues for hevc_vaapi. Signed-off-by: Linjie Fu <linjie.fu@intel.com>
