Subject: vp9-svc: Fix to some frame metrics for real-time mode.
X-Git-Tag: v1.8.0~645^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=bfe85191dda47ce90f655864bf848c71ff6eed22;p=libvpx

vp9-svc: Fix to some frame metrics for real-time mode.

Add condition of LAST frame to the consec_zeromv and
avg_frame_low_motion metrics. This is needed for SVC as
the golden reference is a spatial reference and should
not be included in the metric computation.

Small/negligible change in metrics on RTC set.
