Subject: libs: filter: use macro for returning op default value
X-Git-Tag: 1.19.3~503^2~381
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f232f87f7082957e0ebf470d1df622ccd39a184a;p=platform%2Fupstream%2Fgstreamer.git

libs: filter: use macro for returning op default value

The code is essentially the same for getting all op default
values.  Thus, use a macro to help minimize code duplication
and [hopefully] encourage using the same mechanism for all
default getters.
