Original commit message from CVS: * gst/rtpmanager/gstrtpbin.c: (gst_rtp_bin_associate), (gst_rtp_bin_handle_sync), (create_stream), (free_stream), (new_ssrc_pad_found): Remove internal sync pad, use signals instead to get lip-sync notifications. * gst/rtpmanager/gstrtpjitterbuffer.c: (gst_rtp_jitter_buffer_base_init), (gst_rtp_jitter_buffer_class_init), (gst_rtp_jitter_buffer_internal_links), (create_rtcp_sink), (remove_rtcp_sink), (gst_rtp_jitter_buffer_request_new_pad), (gst_rtp_jitter_buffer_release_pad), (gst_rtp_jitter_buffer_sink_rtcp_event), (gst_rtp_jitter_buffer_chain_rtcp), (gst_rtp_jitter_buffer_get_property): * gst/rtpmanager/gstrtpjitterbuffer.h: Make it possible to send SR packets to the jitterbuffer. Check if the SR timestamps are valid by comparing them to the RTP timestamps. Signal the SR packet and the timing information to listeners. * gst/rtpmanager/gstrtpssrcdemux.c: (create_demux_pad_for_ssrc), (gst_rtp_ssrc_demux_rtcp_chain), (gst_rtp_ssrc_demux_src_query): Remove some unused code. * gst/rtpmanager/rtpjitterbuffer.c: (rtp_jitter_buffer_reset_skew), (calculate_skew), (rtp_jitter_buffer_get_sync): * gst/rtpmanager/rtpjitterbuffer.h: Keep track of the last seen RTP timestamp so that we can filter out invalid SR packets.
