Browse source 
Original commit message from CVS:
* gst/gsturi.c: (gst_uri_protocol_check_internal),
(gst_uri_get_protocol), (gst_uri_has_protocol),
(gst_uri_construct), (gst_uri_handler_set_uri):
A valid URI scheme can also include '+', '-' and '.' additional
to alphanumeric characters as per RFC 3986 Section 3.1.
Handle URI schemes case insensitive in all places and convert
to lower-case when constructing an URI or setting an URI with
the GstURIHandler interface. Fixes bug #528868.
All elements can still assume (as before) that they will
get passed URIs with a lower-case URI scheme by the GstURIHandler
interface.
