From 4b7396917b473f9dcde7e7bd94bff4181f7730c1 Mon Sep 17 00:00:00 2001 From: David Schleef Date: Sat, 15 Dec 2007 06:33:36 +0000 Subject: [PATCH] [035/906] * sys/glsink/gstvideo-common.c: * sys/glsink/gstvideo-common.h: Pull together some common raw video functions into one location. This should eventually move to -base. * sys/glsink/Makefile.am: * sys/glsink/glimagesink.c: * sys/glsink/glimagesink.h: * sys/glsink/glvideo.c: * sys/glsink/glvideo.h: * sys/glsink/gstopengl.c: Use the new video-common.h stuff.
