2009-06-29rtpbin: do better cleanup of the src ghostpadsWim Taymans1-14/+30
Connect to the pad-removed signal of the ptdemux elements so that we remove the ghostpads for them. Fixes cleanup when going to NULL as well as when releasing the sinkpads. Fixes #561752
2009-06-29rtpbin: add SDES propertyWim Taymans1-168/+28
Remove all individual SDES properties and use one sdes property that takes a GstStructure instead. This will allow us to add more custom stuff to the SDES messages later.
2009-05-29rtpbin: Transform the right session sdes messageOlivier Crête1-3/+1
Fixes #584165
2009-05-25rtpbin: remove ptdemux ghostpadsWim Taymans1-0/+13
2009-05-22rtpbin: add to new signal to remove SSRC padsWim Taymans1-15/+6
2009-05-22rtpbin: use our ghostpads instead of its targetWim Taymans1-44/+46
Since we keep a reference to our ghostpads, we can use them to track sessions. This avoid us having to mess with the target of the ghostpad.
2009-05-22rtpbin: don't warn when getting request pads twiceWim Taymans1-52/+34
Allow getting the request pads multiple times, just return the previously created pads.
2009-05-22rtpbin: set target state on new elementsWim Taymans1-20/+37
Set the state on newly added elements to the state of the parent. Add some debug info and do some cleanups
2009-05-22rtpbin: unref requests pads after releasingWim Taymans1-0/+4
2009-05-22rtpbin: Implement releasing the streamsOlivier Crête1-21/+53
See #561752
2009-05-22rtpbin: Keep jb signals handlerOlivier Crête1-3/+7
Keep the signal handlers so they can be disconnected at release time See #561752
2009-05-22rtpbin: use the right lock for the sessionsWim Taymans1-0/+4
Use the right lock when iterating the sessions.
2009-05-22rtpbin: Free session if request pads are releasedOlivier Crête1-3/+8
Free the session when all the request pads are released. Don't mess with the session list in free_session as it is called from a foreach on that list. Set the state of the upstream element to NULL first. See #561752
2009-05-22rtpbin: Implement relasing of the rtp recv padOlivier Crête1-2/+17

2009-04-15rtpbin: we should not provide a clockWim Taymans1-15/+0
There is no need to provide a clock.
2009-03-27rtpbin: add on_npt_stop signalWim Taymans1-0/+23
Add the on_npt_stop signal to rtpbin and rtpjitterbuffer to notify the application that the NPT stop position has been reached.

Original commit message from CVS: * gst/rtpmanager/gstrtpbin.c: (create_session), (gst_rtp_bin_associate), (gst_rtp_bin_sync_chain): Do not try to adjust the offset of streams for which we have not yet seen an SR packet.

2008-09-05gst/rtpmanager/gstrtpbin.*: Add signal to notify listeners when a sender ↵Wim Taymans1-16/+44
becomes a receiver. Original commit message from CVS: * gst/rtpmanager/gstrtpbin.c: (on_sender_timeout), (create_session), (gst_rtp_bin_associate), (gst_rtp_bin_sync_chain), (gst_rtp_bin_class_init), (gst_rtp_bin_request_new_pad): * gst/rtpmanager/gstrtpbin.h: Add signal to notify listeners when a sender becomes a receiver. Tweak lip-sync code, don't store our own copy of the ts-offset of the jitterbuffer, don't adjust sync if the change is less than 4msec. Get the RTP timestamp <-> GStreamer timestamp relation directly from the jitterbuffer instead of our inaccurate version from the source. * gst/rtpmanager/gstrtpjitterbuffer.c: (gst_rtp_jitter_buffer_chain), (gst_rtp_jitter_buffer_loop), (gst_rtp_jitter_buffer_get_sync): * gst/rtpmanager/gstrtpjitterbuffer.h: Add G_LIKELY macros, use global defines for max packet reorder and dropouts.

Keep track of the extended RTP timestamp so that we can report the RTP timestamp <-> GStreamer timestamp relation for lip-sync. Remove server timestamp gap detection code, the server can sometimes make a huge gap in timestamps (talk spurts,...) see #549774. Detect timetamp weirdness instead by observing the sender/receiver timestamp relation and resync if it changes more than 1 second. Add method to report about the current rtp <-> gst timestamp relation which is needed for lip-sync. * gst/rtpmanager/rtpsession.c: (rtp_session_class_init), (on_sender_timeout), (check_collision), (rtp_session_process_sr), (session_cleanup): * gst/rtpmanager/rtpsession.h: Add sender timeout signal.
