Subject: Update to cyclic refresh:
X-Git-Tag: v1.2.0~75
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=b501251e2e7a4db4cb1ca2d6cbf24176d2a065dc;p=libvpx

Update to cyclic refresh:

Set the seg map to 0 for key frame.

In previous commit on cyclic refresh, the seg map for key frame
was not reset, and instead used the seg map from last frame.
