Subject: fix an assumption about uv_stride
X-Git-Tag: v1.3.0~1151^2~62^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=045c53f51e6b1ff6b9ba2f5651bf3b206fb08e1e;p=libvpx

fix an assumption about uv_stride

Use the uv_stride from the framebuffer rather than deriving it from the
y_stride.
