Use the element START_TIME to keep track of the running time when the pipeline
paused so that it can be used to restore the base_time.
Take the start_time before setting the children to PAUSED so that we can
distribute the start_time to the children.
If that block is entered, then start_time becomes GST_CLOCK_TIME_NONE.
Since start_time is invalid, the code will enter the block at line 434 and
new_base_time will be set there.
Original commit message from CVS:
* gst/gstinfo.c:
Explain why we copy the list.
* gst/gstpipeline.c:
Improve docs.
* gst/gstutils.c:
Add one debug-log statement to help tracing probelms with linking pads.
Original commit message from CVS:
* gst/gstbin.c: (gst_bin_class_init), (clear_queue),
(do_bin_latency), (gst_bin_change_state_func):
* gst/gstpipeline.c: (gst_pipeline_change_state):
Move latency query from GstPipeline to GstBin so that we can also
use it when async-handling is enabled on bins.
Original commit message from CVS:
* gst/gstpipeline.c: (reset_stream_time),
(gst_pipeline_change_state), (gst_pipeline_set_new_stream_time):
Only try to select a different pipeline clock when we went back to
PAUSED and not when we merely got flushed.
Original commit message from CVS:
* gst/gstpipeline.c: (gst_pipeline_change_state):
Modify the clock distribution path in PAUSED->PLAYING so that we
never attempt to choose a new clock unless we're actually leaving
the PAUSED state for the first time. This prevents choosing a
different clock when the state_change gets called for a 2nd time due
to some element doing an async state change.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
Add new element field and method.

(bin_push_state_continue), (bin_handle_async_start),
(bin_handle_async_done), (gst_bin_handle_message_func):
Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.

* gst/gstelement.h:
Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)
Export gst_element_change_state() method so that subclasses can use it.

* gst/gstpipeline.c: (gst_pipeline_class_init),
(reset_stream_time), (gst_pipeline_change_state),
(gst_pipeline_handle_message), (gst_pipeline_set_new_stream_time):
Using the new ASYNC_START message we can reset the base_time when
needed. This can then be used to implement base_time redistribution in
flushing seeks so that we can remove the explicit seek handling.
Perform latency query and configuration when going to PLAYING.
* libs/gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_query), (gst_base_sink_change_state):
Post new ASYNC_START/ASYNC_DONE messages.

Fix test because the bin will not set the async element to PLAYING right
away.

Make the message check a little stronger.
Handle ASYNC messages.

Expect ASYNC_DONE messages.
Original commit message from CVS:

(gst_pipeline_provide_clock_func), (gst_pipeline_set_delay):
Don't ref a NULL clock in _provide_clock_func().
Don't allow an INVALID delay.
Don't try to calculate base_time with an invalid start_time.
Also distribute and notify a NULL clock when it was selected.
* tools/gst-launch.c: (event_loop):
Don't crash when a NULL clock was selected in the pipeline.
Original commit message from CVS:
* gst/gstobject.c: (gst_object_set_parent):
* gst/gstpipeline.c: (do_pipeline_seek):
Small cleanups in docs and code.
* gst/gstsegment.c: (gst_segment_clip):
* tests/check/gst/gstsegment.c: (GST_START_TEST):
if stop == start and start is in the segment, no clipping should be
done. Also add a test for this.
Original commit message from CVS:
* gst/gstcaps.c: (gst_caps_replace):
Fix crasher when passed NULL. Doc clarification.
Optimize for the trivial case.
* gst/gstpipeline.c: (gst_pipeline_change_state):
Small cleanups.
* libs/gst/base/gstbasesrc.c: (gst_base_src_loop):
Small documentation cleanup.
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_buffer_alloc):
Don't use silly gst_pad_get_negotiated_caps, GST_PAD_CAPS
is what we need and it avoids a whole lot of redundant
refcount operations.
Original commit message from CVS:
* gst/gstpipeline.c: (gst_pipeline_init):
When we create a pipeline bus, initially create it in flushing mode.
Fixes leaks in at least one test, and makes a new pipeline work the
same as one that has gone to READY and then back to NULL.
* gst/gstelement.c:
Typo fix in docs.

gst_pipeline_get_auto_flush_bus() to disable automatic
flushing of the pipeline's GstBus when going from READY
to NULL state (#332045).

Implement master/slave. When setting a clock as a slave, a
periodic timeout is scheduled to sample master and slave times.
Then the slave clock is recalibrated to match offset and rate
of the master clock.
Update logging a bit.
Add flag so that a clock can state that is cannot be slaved to
another clock.

problem of the probe not being called, because that's not the
issue I'm looking at. Add a check that setting stream_time to NONE
