This is a re-implementation of the RTP elements that are submitted in 2013 to handle RTP streams. The elements handle a correct connection for the bi-directional use of the RTCP sockets. https://bugzilla.gnome.org/show_bug.cgi?id=703111 The rtpsink and rtpsrc elements add an URI interface so that streams can be decoded with decodebin using the rtp:// interface. The code can be used as follows ``` gst-launch-1.0 videotestsrc ! x264enc ! rtph264pay config-interval=3 ! rtpsink uri=rtp://239.1.1.1:1234 gst-launch-1.0 videotestsrc ! x264enc ! rtph264pay config-interval=1 ! rtpsink uri=rtp://239.1.2.3:5000 gst-launch-1.0 rtpsrc uri=rtp://239.1.2.3:5000?encoding-name=H264 ! rtph264depay ! avdec_h264 ! videoconvert ! xvimagesink gst-launch-1.0 videotestsrc ! avenc_mpeg4 ! rtpmp4vpay config-interval=1 ! rtpsink uri=rtp://239.1.2.3:5000 gst-launch-1.0 rtpsrc uri=rtp://239.1.2.3:5000?encoding-name=MP4V-ES ! rtpmp4vdepay ! avdec_mpeg4 ! videoconvert ! xvimagesink ``` rtpmanagerbad: add pkg-config rtpmanagerbad: Rtp should be uppercase rtpmanagerbad: add G_OS_WIN32 for shielding unix headers rtpmanagerbad: remove Since from documentation rtpmanagerbad: rename lib name from nrtp to rtpmanagerbad rtpmanagerbad: sync meson.build with other modules rtpmanagerbad: add Makefile.am rtpmanagerbad: use GstElement to count pads rtpmanagerbad: use gst_bin_set_suppressed_flags rtpmanagerbad: check element creation rtpmanagerbad: post message when trying to access missing rtpbin rtpmanagerbad: return FALSE with g_return tests rtpmanagerbad: use gsocket multicast check rtpmanagerbad: use gst_caps_new_empty_simple iso gst_caps_from_string rtpmanagerbad: sync with gstrtppayloads.h rtpmanagerbad: correct media type X-GST rtpmanagerbad: test if a compatible pad was found rtpmanagerbad: remove evil copy of GstRTPPayloadInfo rtpmanagerbad: add gio_dep to meson rtpmanagerbad: revert to old glib boilerplate GStreamer 1.16 does not yet support the newer GLib templates, so revert. rtpmanagerbad: return GST_STATE_CHANGE_NO_PREROLL for live sources for live sources, NO_PREROLL should be returned for PLAYING->PAUSED and READY->PAUSED transitions. rtpmanagerbad: use GstElement pad counting rtpmanagerbad: just use template name to request pad rtpmanagerbad: remove commented code rtpmanagerbad: use funnel to send multiple streams on one socket rtpmanagerbad: avoid beaches beaches should only be used during the summer, so rewrite the code to return explicitly and avoid beaches during the winter. rtpmanagerbad: add copyright to test code rtpmanagerbad: g_free is NULL safe rtpmanagerbad: do not trace rtpbin rtpmanagerbad: return NULL explitly rtpmanagerbad: warn when data port is not even According to RFC 3550, RTP data should be sent on even ports, while RTCP is sent on the following odd port. rtpmanagerbad: document port allocation in rtpsink/src rtpmanagerbad: improve uri description rtpmanagerbad: add comment re-use socket rtpmanagerbad: rename gst_object_set_properties_from_uri_query rtpmanagerbad: loan prop/val setter from rist rtpmanagerbad: rtpsrc: fix unitialised pointer rtpmanagerbad: fix silly typo rtpmanagerbad: test for empty key/value rtpmanagerbad: rtpsrc: deprecate ssrc collision to INFO rtpmanagerbad: sync debug with rist rtpmanagerbad: small strings allocated on stack rtpmanagerbad: correct rename rtpmanagerbad: add locking on prop setters/getters Locking is added because the URI allows to access the properties too. rtpmanagerbad: allow for RTCP through NAT rtpmanagerbad: move gio to header file rtpmanagerbad: free small strings too rtpmanagerbad: ttl_mc for ttl on dynudpsink rtpmanagerbad: add comments on the URI registered rtpmanagerbad: correct macro after file rename rtpmanagerbad: code style rtpmanagerbad: handle wrong URIs in setter rtpmanagerbad: nit URI notation correction In an URI, the first key/value pair should not have an ampersand, the parser did not die though.
