Subject: Avoid re-allocating fp_motion_vector_info
X-Git-Tag: v1.10.0-rc1~78
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=6ac8a0c9b01b9a4b65e5926814d399f13981902f;p=libvpx

Avoid re-allocating fp_motion_vector_info

Replace fp_motion_vector_info_init() by
fp_motion_vector_info_reset() in first_pass_encode()
