From 9bde778e7362d42885f76d32dd77957a23891798 Mon Sep 17 00:00:00 2001 From: Luca Abeni Date: Wed, 20 Dec 2006 13:09:29 +0000 Subject: [PATCH] Allow to compile swscale's non-SIMD code under the LGPL license. Since mplayer always define CONFIG_GPL, this commit should not change anything for mplayer.
