(gst_base_sink_queue_object_unlocked),
(gst_base_sink_queue_object), (gst_base_sink_event),
(gst_base_sink_needs_preroll), (gst_base_sink_chain_unlocked):
When we received EOS and are waiting for when to post the EOS message,
our state is prerolled and we should not return ASYNC.
Reorganize some code paths to implement this behavior.
* tests/check/generic/sinks.c: (send_eos), (GST_START_TEST),
(gst_sinks_suite):
Add unit test to verify above EOS fix.
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_event),
(gst_base_sink_get_position):
Don't try to preroll non-async elements after a flush.
Subtract latency form clock times when reporting position.

(gst_base_src_change_state):
Rework the locking of basesrc in a similar fashion to basesink. We
basically have one lock (LIVE_LOCK) protecting the dataflow. This allows
us to handle live sources and semi live ones much better.
Simplify flushing.
Fix unlocking when seeking, shutting down and pausing in live sources.
Original commit message from CVS:
* libs/gst/base/gstbasesrc.c: (gst_base_src_do_sync),
(gst_base_src_get_range), (gst_base_src_change_state):
Call unlock for live sources so that they can't get stuck in _create and
produce a buffer before they are set back to PLAYING.
Original commit message from CVS:
* libs/gst/base/gstbasesrc.c: (gst_base_src_change_state):
Also initialize the counter that calculates the first timestamp on a
buffer correctly for non-live sources.

* libs/gst/base/gstbasesink.c: (gst_base_sink_query_latency),
(gst_base_sink_event), (gst_base_sink_query),
(gst_base_sink_change_state):
Simplify latency query.
When not synchronizing, we can report latency without querying the peer
element.
Original commit message from CVS:
* libs/gst/base/gstbasesink.c: (gst_base_sink_preroll_queue_flush),
(gst_base_sink_event), (gst_base_sink_change_state):
Sinks that don't preroll can always be queried for the latency.
Don't post ASYNC start when we are not async.

(gst_base_sink_set_flushing), (gst_base_sink_query),
(gst_base_sink_change_state):
Latency query is allowed after we are prerolled. Introduce a new flag
for this and stop abusing other variables.
Original commit message from CVS:
* libs/gst/base/gstbasesrc.c: (gst_base_src_send_event):
Push OOB events downstream when we get them in send_event. This allows
the application to insert events in the pipeline.
Add some more comments.
Original commit message from CVS:
* libs/gst/base/gstbasesrc.c: (gst_base_src_query_latency),

Clean up the timestamping and syncing code for pseudo live sources.
Original commit message from CVS:
* docs/design/part-live-source.txt:
Add docs on how live sources should timestamp.
* libs/gst/base/gstbasesrc.c: (gst_base_src_do_sync):
Add some more debug info.
For subclasses that are live and like to sync, add aditional startup
latency to sync time and timestamps so that we timstamp according to the
design doc.

* tests/check/pipelines/simple-launch-lines.c
(test_state_change_returns): Enable pull-mode tests now that
basesink has been fixed.
* libs/gst/base/gstbasesink.c (gst_base_sink_needs_preroll):
Changed from gst_base_sink_is_prerolled, reversing the sense of
the return value. Returns FALSE also if the sink is in pull mode,
in which case it needs no preroll.
(gst_base_sink_query, gst_base_sink_change_state): Update for
needs_preroll change.
(gst_base_sink_change_state): Add a case for READY_TO_PAUSED after
chaining up, in which we return SUCCESS directly if we activated
in pull mode instead of ASYNC. Involves countering an async_start
message sent before chaining up; not sure if this is correct, in
an ideal world we only send async-start when activating in push
mode.

(gst_single_queue_new):
Keep track of time in the queue by measuring the difference between
running_time on input and output. This gives more accurate results and
can compensate for segments correctly.
Make a queue by default only 5 buffers deep. We will now increase the
buffer size depending on the filledness of the other queues.
Factor out commong flush code.
Make sure we don't add additional refcounts to buffers when we can avoid
it.
Propagate GstFlowReturn differently.
Use GSlice for intermediate GstMultiQueueItems.
Keep track of EOS.
Resize queues on over and underruns based on filled level of other
queues.
When checking if the queue is filled, prefer to measure in time if we
can and fall back to bytes when no time is known.
* plugins/elements/gstqueue.c:
Fix return value.
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_sink_event):
Work around the brokenness of the event vmethod in basetransform. Prefer
to return TRUE when the subclass returned FALSE (meaning don't forward
the event).
* libs/gst/base/gstbasetransform.h:
Clarify the docs.
Original commit message from CVS:

Fix multiqueue leaking buffers and events when downstream or the
queue are flushing. Make refcounting assumptions explicit and
document them (shouldn't break existing code that uses it other than
maybe leak miniobjects, but that already happens anyway). Add unit
test for the most common flushing case. Fixes#423700.

Original commit message from CVS:

Properly set the last_stop position on GstSegment. This will only happen
if there is a buffer to push out.
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_buffer_alloc):
always_in_place does not mean that the sink and source caps are the
same! Make sure we don't blindly proxy the buffer_alloc in this case.

API: gst_base_src_query_latency(). Added method so that subclasses can

Original commit message from CVS:
* libs/gst/base/gstbasetransform.c: (gst_base_transform_activate):
Make sure streaming has finished before calling the ::stop() vfunc,
since that vfunc might clear state which is being used in the
streaming thread. This fixes a race that caused crashes in
audioresample when shutting down a pipeline (#420106).

* libs/gst/base/gstbasesrc.h:
Allow basesrc derived classes to execute seeks in other formats
by providing a prepare_seek_segment vmethod. Sub-classes can choose
to prepare the GstSegment in any format that their perform_seek method
will be able to understand. The default implementation provides the
old behaviour of attempting to convert the seek offsets to the
configured native format.

merging them together rather than copying data out into new memory.
