this would be better off in libavcodec. if you can, submit a diff of svn libavcodec to ffmpeg-devel. at least it will be a starting point. i'll add it to the ffmpeg small projects wiki.

as for your patch, it seems to remove the check for libdca for some reason.

-echocheck "libdca support"
-if test "$_libdca" = auto ; then
-  _libdca=no
-  cat > $TMPC << EOF
-#include <inttypes.h>
-#include <dts.h>
-int main(void) { dts_init (0); return 0; }
-EOF
-  cc_check -ldts $_ld_lm && _libdca=yes
-fi
-if test "$_libdca" = yes ; then
-  _def_libdca='#define USE_LIBDCA 1'
-  _ld_extra="$_ld_extra -ldts"
-  _codecmodules="libdca $_codecmodules"
