# Patch for vlc (www.videolan.org)
# and xine (xine.sourceforge.net)
# ===============================
# 3.5.2 The Xv video-out plugin fails to compile!
#
#      If you want to have Xv support compiled in, make sure you either
#      have
#      a shared Xv library on your system, e.g. ls /usr/X11R6/lib/libXv*
#      should give you some .so libs, like this:
#
#      /usr/X11R6/lib/libXv.a
#      /usr/X11R6/lib/libXv.so
#      /usr/X11R6/lib/libXv.so.1
#
#      Alternatively you need to have libtool 1.4 or newer installed. If
#      not
#      and you only got libXv.a you can create the shared versions
#      yourself:
#
#       ld --whole-archive -shared -o libXv.so.1 libXv.a
#       ln -s libXv.so.1 libXv.so
#       ldconfig
#
#      Now you should be ready to build the Xv video-out plugin on your
#      system.
