From 0eb8f8998114855d8d200a70c357d482e8f444fc Mon Sep 17 00:00:00 2001 From: Leo Liu Date: Mon, 22 Sep 2014 14:07:13 -0400 Subject: st/vdpau: move common functions to util Break out these functions so that they can be shared with a other state trackers. They will be used in subsequent patches for the new VA-API state tracker.
