Subject: vp8 denoiser fix: Update denoised altref on key frame.
X-Git-Tag: v1.4.0~1174^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f909e43abc2cbb7bcb782246e7d3b640c9cf7536;p=platform%2Fupstream%2Flibvpx.git

vp8 denoiser fix: Update denoised altref on key frame.

On a key frame, the denoised-running_avg for all references
frames should be updated with the source.
The altref denoised-running_avg was not being updated on key frame,
this fixes that.
