For xmp, we probably don't want to rewrite exempi
(http://libopenraw.freedesktop.org/wiki/Exempi)

SLOC    Directory    SLOC-by-Language (Sorted)
34656   source          cpp=34656
1757    exempi          cpp=1737,sh=20

exempi is BSD.


Kind of similar story for libexif.
http://libexif.sourceforge.net/
and this one is LGPL.

(removed some irrelevant parts). So this would be the first case of
gst-plugins-base/gst-libs/ext/tag/gst{xmp,exif}tag.{c,h}

What are the opinions one tag support libaries in base that have external deps.
Basically plugins would either need some code like if
gst_tag_is_exif_supported() or we could maybe even handle that in the tag
libary to have stubs if the dependency is missing. Any preference here?
