From bf6b1747ae4bad46dbbf5fa2189a18b45c1d6b38 Mon Sep 17 00:00:00 2001
From: Daniel Caujolle-Bert <f1rmb@users.sourceforge.net>
Date: Mon, 13 Oct 2003 11:47:11 +0000
Subject: Add vcdx plugin(CVS) and dependent libs(no CVS, broken API). Ability
 to use external libs (--with-external-vcdnav), disable vcdx build and build
 old vcd instead (--disable-vcdx). This last feature is useful since vcdx take
 /hours/ to start playback, that can help people who don't want vcd
 navigation. Remove all .la files, even in subdirs (eg: post)

CVS patchset: 5505
CVS date: 2003/10/13 11:47:11
