Subject: vp8: Set default denoiser_decision to copy for UV channel.
X-Git-Tag: v1.4.0~1168^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=daed770d99d4d2bdb091681e5be5a1835759b169;p=libvpx

vp8: Set default denoiser_decision to copy for UV channel.

Since the UV decision to denoise is based on Y, we need to set
the default/initial denoiser decision_u/v to COPY_BLOCK,
to make sure if no uv_denoiser is applied we still update
(uv)running_avg with source.
