Move the flag to indicate that a new_base_time should be distributed to the
pipeline, from the async_start to the async_done message. This would allow us to
decide when to reset the pipeline time based on other reasons than the
FLUSH_START event.
The main goal eventually is to make the FLUSH events not reset time at all but
reset the time based on the first buffer or segment that prerolls the pipeline
again.
This reverts commit cf4fbc005c.
This change did not improve the situation for bindings because
queries are usually created, then directly passed to a function
and not stored elsewhere, and the writability problem with
miniobjects usually happens with buffers or caps instead.
Some tests (e.g. elements/capsfilter) have pipelines with dangling
sinkpads and without a sink element. These pipelines can never post
an EOS message (because this is only valid by a sink) and as such
should never get an EOS message posted by the bin.
API: GstElement::state_changed
This is always called when the state of an element has changed and
before the corresponding state-changed message is posted on the bus.
Drop in old GstBus code for the release to play it safe, since
regressions that are apparently hard to track down and reproduce
have been reported (on windows/OSX mostly) against the lockfree
version, and more time is needed to fix them.

This allows to only create the socketpair when it is really required instead
of always creating it and immediately destroying it again for child buses.
https://bugzilla.gnome.org/show_bug.cgi?id=647005
This is used by GstBin to create a child bus without
a socketpair because child buses will always work
synchronous. Otherwise too many sockets could be
created and the limit of file descriptors for the
process could be reached.
Fixes bug #646624.
basesrc's default event handler returns TRUE regardless of whether the
event is handled or not. This fixes the handler to conform with the
expected behaviour (which is to only return TRUE when the event has
actually benn handled). gst_bin_do_latency_func() depended on this
(incorrect) behaviour, and is now modified as well.
(Remaining 1-liner change in gstbasesrc.c is to keep gst-indent happy)
Track elements tagged with the IS_SOURCE flag in a similar way we track the sink
elements. This allows us to efficiently dispatch downstream events to the right
elements.
Add an option to forward all the internal messages that would otherwise be
filtered such as EOS, SEGMENT and ASYNC messages.
This allows the application to, for example, detect that a partial pipeline is
prerolled or reached eos.
The original messages are wrapped inside an element message because the parent
bins are not supposed to see those internal messages escape.
When there is a sink inside a bin, the SINK flag is set on the bin. When we are
trying to iterate the source elements, also include the bins with the SINK flag
because they could also contain source elements, in which case they are also a
source.
This solves the case where sending an EOS to a pipeline didn't get dispatched to
all source elements.
See #625597
Since everything GstXML related has been deprecated, we can now skip the
libxml includes from the public headers when GST_DISABLE_DEPRECATED is
defined.
See #463435.
Pipeline serialisation to and from XML is horribly broken for all
but the most simple use cases, and will likely never be fixed.
Make sure everyone playing around with these tools is aware of
this, to avoid frustration. See countless bug reports in bugzilla.
Fixes bug #622685.
When an error message is received on the bus, mark the bin as being in the error
state and unlock all current _get_state() calls with an error.
Fixes#505770
When an element is removed from a bin because it caused a state change error,
don't unref the child twice.
Add some more debug info.
Add a unit test for this error.
Fixes#615756
Right now deleyed set would only try for first set of children. We need to keep
trying to support arbitrary deep hierarchies (like in playbin2 with auto*sinks).
Also GstBin would need to actualy emit the child-added/removed signal as it
implements the iface. Fixes#613215.
Never skip the state change to playing, even if the element is already in the
right state. We need this because we also distribute the base_time while doing
the state change and skipping this step would leave some elements without a new
base_time.
Fixes#600313
There's not much point in using GST_DEBUG_FUNCPTR with GObject
virtual functions such as get_property, set_propery, finalize and
dispose, since they'll never be used by anyone anyway. Saves a
few bytes and possibly a tenth of a polar bear.
Post the structure change messages on the sinkpads of the elements. This allows
us to catch unlinked pads earlier without ending up with inconsistent element
degrees.
When we detect a pad unlink in progress, we will not be updating the degree of
the parent element. This can cause false loop detected warnings because the
degree counter is invalid. Handle this case by marking the iterator as 'dirty'
when we detect a pad unlink and avoid emiting the warning in this case. We have
to continue our state change as good as we can, we will eventually resync when
the pad unlink completed.
When an element is added to the bin, only set the index if we have a
cached index, rather than setting a NULL index on elements that might
have a default index object of their own.
Cache the last index that was set with _set_index() and return this in the
_get_index() call.
Set the cached index on newly added elements.
Fixes#566881
When we get an ASYNC_DONE message when a state change was busy, set the
pending_async_done flag so that after the state change completes, the bin can
check if all async elements are finished. Don't only do this for the bin itself
but for all elements.
This fixes some bins in bins that simulate async state changes by posting ASYNC
messages (such as sdpparse in uridecodebin/playbin2).
Bin collects segment-start messages and segent-done messages. it posts a
segment-done message to its parent, once it has received a segment-done for
each segment-start. Imho it should also send a segment-start if it receives the
first segment start and if parent is !=NULL. This is needed for bins in bins,
so that also higher order bins can group segment-starts and segment-dones.
Right now higher order bins will post a segment-done for each segment-done
received.

Remove GST_DISABLE_(ENUMTYPES|INDEX|URI) everywhere.
Disabling the indexers and URI handler code will only reduce the
required amount of memory by a very small amount but on the other hand
requires much more maintaince work. Apart from that many places of
code are broken when disabling them.
Disabling the enum types doesn't reduce the required amount of memory
by more than a few bytes and makes it hard to fix bugs like #539772,
i.e. use the enums as GObject properties.

Documentation updates.
Original commit message from CVS:
* gst/gstbin.c: (activate_pads),
(iterator_activate_fold_with_resync), (gst_bin_src_pads_activate),
(gst_bin_change_state_func):
(de)activate src pads before calling state_change on the childs.
This is to avoid the case where a src ghostpad is blocked (holding the
stream lock), which would block the deactivation of the ghostpad's
target pad.

GhostPads now create their internal GstProxyPad at creation (and not
when they're linked, as it was being done previously).
The internal and target pads are linked straight away.
The data will also travel through the other pad in order to make
pad blocking and probes non-hackish (the probe/block now really happens
on the GhostPad and not on the target).
* gst/gstpad.c: (gst_pad_set_blocked_async),
(gst_pad_link_prepare), (gst_pad_push_event):
Remove previous ghostpad cruft.
* gst/gstutils.c: (gst_pad_add_data_probe),
(gst_pad_add_event_probe), (gst_pad_add_buffer_probe),
(gst_pad_remove_data_probe), (gst_pad_remove_event_probe),
(gst_pad_remove_buffer_probe):
Remove previous ghost pad cruft.
Added more detailed debug statements.
* tests/check/gst/gstghostpad.c: (GST_START_TEST):
Fix the testsuite for refcounting changes.
The comments about who has references were correct, but the refcount
being checked wasn't the same (!?!).
Original commit message from CVS:
* gst/gstbin.c: (compare_interface), (gst_bin_get_by_interface),
(gst_bin_iterate_all_by_interface):
Can't use GPOINTER_TO_INT and GINT_TO_POINTER with GTypes.
GTypes are gulongs and thus the top 4 bytes might be cut
off on some platforms when doing GPOINTER_TO_INT, leading
to invalid GTypes and bad things happening.
Also add a check to make sure the type passed in is really
an interface type.
Original commit message from CVS:
* gst/gstbin.c: (gst_bin_restore_thyself):
* gst/gstxml.c: (gst_xml_make_element):
Fix deserialisation from XML. Set parent manually
instead of using gst_bin_add(), since gst_bin_add()
will unlink all pads of the element being added.
Fixes#341667.
Original commit message from CVS:
* gst/gstbin.c: (bin_query_duration_done), (gst_bin_query):
Make it clear with a FIXME and a real define what the #if 0
previously disabled.
Original commit message from CVS:
Patch by: Stefan Kost <ensonic at sonicpulse dot de>
* gst/gstbin.c: (gst_bin_handle_message_func):
Update docs.
Don't leak bin refcount when a state recalc is
in progress and we delay another one #339808.
Original commit message from CVS:
* gst/gstbin.c: (gst_bin_handle_message_func),
(bin_query_max_init), (bin_query_position_fold),
(bin_query_position_done), (gst_bin_query):
Position query should also take max of all streams.
