Original commit message from CVS: implement URI schemes Elements can now register as a source or sink for a protocol and applications can use gst_element_make_from_uri () to get an element that handles a given URI. This patch provides: - removal of old broken URI handling scheme. - new URI handling using interfaces. - updates for registry to save handled URIs. - interface for URI handlers. - implementation of that in filesrc and filesink for the file:// URI - extension to pipeline parsing to allow specifying only a URI instead of element Does not include: - tests - inclusion in docs build
