From dcce09d64bd13ab13b86307f5a268e5c1e50c7e2 Mon Sep 17 00:00:00 2001 From: Joakim Plate Date: Tue, 5 Jul 2011 00:18:32 +0200 Subject: dxva: Add ability to enable workaround for older ATI cards The workaround needs to be enabled per PCI ID which cannot be detected inside libavcodec. So add a flag to manually enable the alternate behavior.
