Subject: rtspurl: Use gst_uri_join_strings() in gst_rtsp_url_get_request_uri_with_control... 
X-Git-Tag: 1.22.0~1113
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=edb0e47074ed7b84fe3f33858908392aaaa1818a;p=platform%2Fupstream%2Fgstreamer.git

rtspurl: Use gst_uri_join_strings() in gst_rtsp_url_get_request_uri_with_control() instead of a hand-crafted, wrong version

For example the query string of the base must not be taken over to the
request URL unless there is no control path, and control paths can be
absolute and must not be considered relative if they start with a /.
