From 169c077d1d10db9e4938bae193fbd14b25cc5795 Mon Sep 17 00:00:00 2001 From: Leo Liu Date: Tue, 19 Sep 2017 13:00:15 -0400 Subject: [PATCH] st/va/postproc: use progressive target buffer for scaling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Scaling between interlaced buffers, esp. for scale-up, because blit will scale up top filed and bottom field separately. it'll result in the weaving for these buffer with lack of accuracy. So use shader deint for the case.
