dnl *** XVideo ***
dnl Look for the PIC library first, Debian requires it.
dnl Check debian-devel archives for gory details.
dnl 20020110:
dnl At the moment XFree86 doesn't distribute shared libXv due
dnl to unstable API. On many platforms you CAN NOT link a shared
dnl lib to a static non-PIC lib. This is what the xvideo GStreamer
dnl plug-in wants to do. So Debian distributes a PIC compiled
dnl version of the static lib for plug-ins to link to when it is
dnl inappropriate to link the main application to libXv directly.
dnl FIXME: add check if this platform can support linking to a
dnl non-PIC libXv, if not then don not use Xv.
dnl FIXME: perhaps warn user if they have a shared libXv since
dnl this is an error until XFree86 starts shipping one
