ex: file.jpeg has XMP, then we do filesrc ! metadataparse ! jpegdec ! pngenc ! metadatamux ! files
is the metadata still valid? which fields are no valid anymore?
3- Add GST_TYPE_FRACTION support for GStreamer TAGS
4- Have parse, demux and mux? (or just demux and must) see issue (5)
5- After decided issue (4) put more things to gstmetadatacommon (or else create a Class)
