-If you only want to compile gupnp-dlna with a gstreamer-0.10 back-end, you have to
-do the following:
-
-./configure --disable-gstreamer-metadata-backend \
-            --enable-legacy-gstreamer-metadata-backend \
-            --with-default-metadata-backend=gstreamer-legacy
-
-This disables the GStreamer 1.0 back-end, enables the 0.10 back-end and makes
-it the default one.
-
-If you omit the last configure option, the default will be the "normal"
-GStreamer back-end and you need to explicitly set the back-end in your code or
-environment.
