[QUARTZ] Add FFMpeg video wrapper filter (take 3)

[Christian Costa]

Alexandre,

If the possible (even rare) presence of a libavcodec.so lib can causes troubles.
Would it be acceptable to force static linking with a configure check such as this one?

dnl **** Check for avcodec lib ****
AVCODECLIBS=""
LIBS="/usr/lib/libavcodec.a -lz -lm"
AC_CHECK_HEADERS(ffmpeg/avcodec.h,
[AC_TRY_LINK([#include ],[avcodec_init();],
[AC_DEFINE(HAVE_LIBAVCODEC, 1, [Define if you have the avcodec library (libavcodec.a)])
AVCODECLIBS="/usr/lib/libavcodec.a -lz -lm"])])
LIBS="";
AC_SUBST(AVCODECLIBS)

Bye,
Christian
