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.
* gst/gstghostpad.c: (gst_proxy_pad_do_query_type),
(gst_proxy_pad_do_event), (gst_proxy_pad_do_query),
(gst_proxy_pad_do_internal_link), (gst_proxy_pad_do_bufferalloc),
(gst_proxy_pad_do_chain), (gst_proxy_pad_do_getrange),
(gst_proxy_pad_do_checkgetrange), (gst_proxy_pad_do_getcaps),
(gst_proxy_pad_do_acceptcaps), (gst_proxy_pad_do_fixatecaps),

(gst_ghost_pad_do_link), (gst_ghost_pad_do_unlink),
(gst_ghost_pad_dispose), (gst_ghost_pad_new_no_target),
(gst_ghost_pad_new), (gst_ghost_pad_set_target):
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.

Clean up references to the clock provider when disposed or when
handling a clock-lost message from it.
Unref sinks when performing a query via gst_iterator_fold, as the
gst_bin_iterate_sinks iterator refs each item. (Fixes#323874)

* gst/gstclock.h:
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.

(GstElementClass::change_state): Pass the GstStateChange along as
an argument. Helps language bindings, so they don't have to use
tricky lock-needing macros like GST_STATE_CHANGE ().
* scripts/update-states (file): New script. Run it on a file to
update it for state naming and API changes. Updates files in
place.
* All files updated for the new API.

that applications can sensibly post custom messages with references
to their own objects.

2005-06-08 Andy Wingo <wingo@pobox.com>
* gst/gstutils.c: RPAD fixes all around.
(gst_element_link_pads): Refcounting fixes.
* tools/gst-inspect.c:
* tools/gst-xmlinspect.c:
* parse/grammar.y:
* gst/base/gsttypefindhelper.c:
* gst/base/gstbasesink.c:
* gst/gstqueue.c: RPAD fixes.
* gst/gstghostpad.h:
* gst/gstghostpad.c: New ghost pad implementation as full proxy
pads. The tricky thing is they provide both source and sink
interfaces, since they proxy the internal pad for the external
pad, and vice versa. Implement with lower-level ProxyPad objects,
with the interior proxy pad as a child of the exterior ghost pad.
Should write a doc on this.
* gst/gstpad.h: s/RPAD/PAD/, s/RealPad/Pad/.
(gst_pad_set_name, gst_pad_set_parent): Macros removed, use
gst_object API.
* gst/gstpad.c: Big changes. No more stub base GstPad, now all
pads are real pads. No ghost pads in this file. Not documenting
the myriad s/RPAD/PAD/ and REALIZE fixes.
(gst_pad_class_init): Add properties for "direction" and
"template". Both are construct-only, so they can't change during
the life of the pad. Fixes properly deriving from GstPad.
(gst_pad_custom_new, gst_pad_custom_new_from_template): Gone. For
derived objects, just set properties when creating the objects via
g_object_new.
(gst_pad_get_parent): Implement as a function, return NULL if the
parent is not an element.
(gst_pad_get_real_parent, gst_pad_add_ghost_pad)
(gst_pad_remove_ghost_pad, gst_pad_realize): Removed.
* gst/gstobject.c (gst_object_class_init): Make name a construct
property. Don't set it in the object init.
* gst/gstelement.c (gst_element_add_pad): Don't allow adding pads
with UNKNOWN direction.
(gst_element_add_ghost_pad): Remove non-orthogonal API. Replace
with gst_element_add_pad (e, gst_ghost_pad_new (name, pad)).
(gst_element_remove_pad): Remove ghost-pad special cases.
(gst_element_pads_activate): Remove rpad cruft.
* gst/gstbin.c (gst_bin_change_state): Use gst_pad_get_parent to
catch the pad's-parent-not-an-element case.
* gst/gst.h: Include gstghostpad.h.
* gst/gst.c (init_post): No more real, ghost pads.
* gst/Makefile.am: Add gstghostpad.[ch].
* check/Makefile.am:
* check/gst/gstbin.c:
* check/gst/gstghostpad.c (test_ghost_pads): Check that linking
into a bin creates ghost pads, and that the refcounts are right.
Partly moved from gstbin.c.

Fix state changes for non sinks. We now change sinks, then elements
with unconnected srcpads, then the rest.
More efficient queue unlocking in flush and state changes.
Set the pad activate mode even if it does not have an activate
function.

ghosting-if-elements-not-in-same-bin behavior.
Original commit message from CVS:
2005-05-14 Andy Wingo <wingo@pobox.com>
* gst/gstbin.c (gst_bin_iterate_sinks): Use sink_iterator_filter
so as to get the refs right.
(sink_iterator_filter): New function, wraps bin_element_is_sink,
unreffing objects that don't pass the filter.
Original commit message from CVS:
2005-05-14 Andy Wingo <wingo@pobox.com>
* gst/gstbin.c (gst_bin_change_state): Fix state changes if a bin
has no sinks.

(bin_element_is_sink), (gst_bin_change_state):
* gst/gstelement.c: (gst_element_add_pad), (gst_element_query):
* gst/gstelement.h:
Identify sinks by their flag to avoid overly complicated
checks (fow now).
Do state changes even for elements not reachable from the
sinks.
BaseSink is a sink now :)
Some more debugging info in the basesrc.
Original commit message from CVS:
* gst/gstbin.c: (gst_bin_add_func), (cb_parent_unset),
(gst_bin_get_state):
If a child is removed from a bin while we remove the child from
the bin and while we're retrieving its state, signal this to the
get_state function so we abort the wait (instead of waiting for
a timeout) and can immediately re-iterate over all other elements.
Original commit message from CVS:
2005-05-10 Andy Wingo <wingo@pobox.com>
* gst/elements/gstfakesink.c (gst_fakesink_render): Er, emit with
*all* the arguments.
* gst/base/gstbasetransform.c (gst_base_transform_event): Grab the
stream lock if it's a FLUSH_DONE; normal flushes don't get the
lock (according to the docs -- if this is wrong change the docs).
* gst/gstpipeline.c (gst_pipeline_change_state): Set the bus to
flush messages in the NULL state.
* gst/gstbus.c (gst_bus_post): If a bus is flushing, unref the
message immediately and return.
(gst_bus_set_flushing): New function. If a bus is flushing, it
flushes out any queued messages and immediately unrefs new
messages. This is so when an element goes to NULL, all of the
unhandled messages coming from it can be freed, and their
references to the element dropped. In other words: message source
ref considered harmful :P
* gst/gstbin.c (gst_bin_change_state): Unref peer element when
we're finished with it.
* gst/gstmessage.c (gst_message_new_state_changed):
Original commit message from CVS:
Added state change code.
Added/updated docs.
Added sink base class, make fakesink extend the base class.
Small cleanups in GstPipeline.
Original commit message from CVS:
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_set_manager),
(gst_bin_send_event):
Add default event/set_manager handlers. The set_manager handler
takes care that the manager is distributed over kids that were
already in the bin before the manager was set. The event handler
is a utility virtual function that sends the event over all sinks,
so that gst_element_send_event (bin, event); has the expected
behaviour.
* gst/gstpad.c: (gst_pad_event_default):
Re-install default event handling for discontinuities, so that
seeking works without requiring hacks in applications or extra
code in sinks.
* gst/gstpipeline.c: (gst_pipeline_class_init),
(gst_pipeline_send_event):
Half hack, half utility: set a pipeline to PAUSED for seek events,
since that is the only way we can guarantee a/v sync. Means that
you can do gst_element_seek (pipeline, method, pos); on a pipeline
and it "just works".
Original commit message from CVS:
Next big merge.

Rearranged gstelement.h
Fix GstIterator comparison bug.
Moved some code to GstPipeline, mostly clocking related.
Original commit message from CVS:
First THREADED backport attempt, focusing on adding locks and
making sure the API is threadsafe. Needs more work. More docs
follow this week.
Original commit message from CVS:
* gst/gstbin.c: (gst_bin_remove_func):
Explicitely make an element release locks in a group when being
remove from a bin.
* gst/gstqueue.c: (gst_queue_chain), (gst_queue_get):
If there's no scheduler, always return immediately (similar to
gst_element_interrupt).

Fix non-recursive state changes to *really* change the state
of the object, and not just call parent_class->state_change.
Fix a lot of lockups caused by this. Fixes#132775. Add test
for the problem. Also enable test to show #142588 (fixed).
* gst/gstthread.c: (gst_thread_change_state),
(gst_thread_child_state_change):
Don't exit the thread if we go to NULL and are inside thread
context. Instead, return control to the main thread context
and exit from there.
* gst/gstelement.c: (gst_element_disable_threadsafe_properties):
Don't unset virtual functions, since those may still be used.
That's not necessarily correct, but suffices for now.

* gst/gstqueue.c (gst_queue_init, gst_queue_link_sink)

pad. The queue will now wait until it is empty and forward the new
caps to the source.
* gst/gstbin.c (gst_bin_set_element_sched)
(gst_bin_unset_element_sched): Make sure that all elements and
links are registered and unregistered with the scheduler exactly
once. This elaborates on a fix by Benjamin Otte, but
guarantees that decoupled elements are also registered.

make state changes work correctly and reentrant (so removing
elements from bins during state changes of bins doesn't cause
segfaults or even wrong states)
add debugging category and debugging output to print children states
* gst/gstbin.c: (gst_bin_dispose):
add some assertion checks
* gst/gstbin.h:
* gst/gstbin.c: (gst_bin_sync_children_state):
deprecate this function - it just does gst_bin_set_state (bin,
GST_STATE (bin))

don't use gst_bin_sync_children_state anymore
* testsuite/states/Makefile.am:

test that the state changes of bins work as expected
* gst/gstthread.c: (gst_thread_class_init), (gst_thread_set_state):
some adjustments to change states correctly, too
* gst/gstthread.c: (gst_thread_change_state):
don't enable/disable "threadsafe" properties, they're unused and
cause random segfaults
* testsuite/threads/Makefile.am:
the queue check randomly passes now, ignore it
Original commit message from CVS:
* gst/gstelement.c: (gst_element_class_init),
(gst_element_set_state), (gst_element_set_state_func):
virutalize gst_element_set_state, use set_state member in class
struct that was already added in 0.7 for this.
* gst/gstbin.c: (gst_bin_foreach), (set_kid_state_func),
(gst_bin_change_state):
make gst_bin_foreach works similar to other foreach functions, plug
memleaks in it. Make functions using it work with the new approach.
Document gst_bin_foreach, so it can be exported if we want to
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_set_state):
use virtualized set_state to make set_state on bins set the state of
all its children.

* gst/gstbin.c (gst_bin_add_func): If we're adding an element
whose state is higher than the bin state, raise the bin state to
ensure that bin state := highest child state.
Original commit message from CVS:
2004-07-11 Andy Wingo <wingo@pobox.com>
* gst/gstbin.c (gst_bin_foreach): New static function. Calls a
procedure on the children of a bin. Assumes that the procedure can
change the set of children.
(set_kid_state_func): New static function.
(gst_bin_change_state): Use gst_bin_foreach to call
set_kid_state_func. Fixes a bug: if a child had a state-change
handler that removes it from the bin, there would be a segfault.
Hopefully it should also work in the case where the state-change
handler on one child adds or removes other children. In any case,
fixes should go to gst_bin_foreach.

Since remove is virtual in GstBin we must not assume the
elements GList to have anothing usefull.
Add some more logging to GstThread and be a bit more paranoid
when resetting the scheduler.
Set the state of the bin to NULL before removing the children.

* gst/gstbin.c: (gst_bin_change_state), (gst_bin_iterate): Fix a big
bug that was breaking pipelines like sinesrc ! { queue ! osssink } when
an error was thrown by osssink. Basically a state change failure for
an element in a different scheduling group was considered as successfull , which means that caps nego was going on and weird stuff happened. Like i wrote in the comment there, if someone want to revert that please
drop me a mail explaining why because i really see no point in keeping
that broken behaviour there.
* gst/gstqueue.c: (gst_queue_get): Add a safety check as the queue CAN
be empty, we then return NULL which will trigger a nice error when
pulling from the pad.

with the type=GST_TYPE_CAPS. This allows language bindings to know
what kind of data they're dealing with.
* gst/gstcaps.c (_gst_caps_value_init): GBoxed values initialize

type implementation, now does the same instead of allocating empty
caps.

GST_DEBUG reorganization
This is a big diff (ca 450k), containing loads of stuff:
- gstinfo.[ch] complete rewrite
- changing of all GST_DEBUG messages to reflect that change
- reorganization of subsystem disabling
- addition of gstconfig.h.in so we can track the disablings
- <gst/gst.h> does not include <unistd.h> and <config.h> anymore
- documentation updated for gstinfo stuff (build the docs yourself to know what changed)
- bugfixes for making of the docs (files from CVS are not deleted anymore
- testsuite for debugging changes in testsuite/debug
expect breakage
Original commit message from CVS:
- make child_state_change a virtual function
- remove unneeded != NULL checks
- implement gst_bin_sync_children_state
Original commit message from CVS:
- Add more --disable options
- fix makefiles to only compile non-disabled features
- some compile fixes.
- removed extratypes, added gsturitype
- make get/set clock on a bin overridable
- some portability fixes for GUINT64
- separate pools from gstregistry.[ch] into gstregistrypool.[ch]
- make gstobject size fixed, even if we disabled load/save
- don't use 'new' as a variable as it is not a valib C++ variable
Original commit message from CVS:
Fix various inconsistencies discovered while attempting to fix --disable-*.
Uraeus: this should fix the bison.simple problem that you've had.
Original commit message from CVS:
- Cleanups
- Added padding to structs
- fixed typechecking/casts
- reduced casts
- implemented remove_element in gstbin
- implemented set index on bin
Original commit message from CVS:
- Reworked the clock to prepare for async notifications
- moved some common scheduler checking to gstbin
- added some vmethods to gstbin for future use
- more fixes to the optimal scheduler

Original commit message from CVS:
- move the state_change signal emit to a better place, before changing
the parent state
- also call the parent state change handler in a bin
Original commit message from CVS:
- Removed unused locking from the cothreads
- use G_*_DECLS in .h files
- remove gstlog.h include from gstobject.h, add to .c files
- removed unused refcounting code from gstobject

SCHED_FIFO and SCHED_RR threads can be constructed.
Original commit message from CVS:
remove the "iterate_started" signal and replace it with pre_iterate and post_iterate callbacks.
Apps can now put a lock around an iterate so they can do stuff on the bin from another thread. much nicer than the signal approach.
Original commit message from CVS:
added a "iterate_started" signal which fires before the iterate of a bin. useful for non-threadsafe operations like seek in threaded pipelines

Original commit message from CVS:
* s/gst_element_install_std_props/gst_element_class_install_std_props/ -- it just makes more sense that way
* added jack element, doesn't quite work right yet but i didn't want to lose the work -- it does build, register,
and attempt to run though
* imposed some restrictions on the naming of request pads to better allow for reverse parsing
* added '%s' to reverse parsing
* added new bin flag to indicate that it is self-iterating, and some lame code in gst-launch to test it out
* fixen on launch-gui
* added pkg-config stuff for the editor's libs
Original commit message from CVS:
make sure cothread->priv is NULL when uninited because we now check it
(added debugging line to gst_bin_remove while debugging)
Original commit message from CVS:
* add two apis:
* gst_element_connect_elements_many (elem1, elem2, ...)
- calls gst_element_connect_elements() in order
- should be called gst_element_connect_many, but we need to rename gst_element_connect_elements first
- simplifies common-case code
* gst_bin_add_many (bin, elem1, ...)
- calls gst_bin_add on all of the elems
- again, simplifying common code
Original commit message from CVS:
* warning fixes
* gst_object_set_name (name, NULL) uniquifies the name globally
- needs robusticizing
* gst_elementfactory_make can now take NULL as a second argument
Original commit message from CVS:
This patch (nearly) completes the removal of vertical events from the
core.
What it does:
- removal of the EVENT signal of GstElement (to be replaced by
g_object_notify)
- changing of the ERROR signal to allow recursive notification (like
deep_notify)
- implementing recursive notification with error events.
- removal of some functions in gstbin.c that are not used anymore.
- The function gst_element_info and gst_element_send_event now do
nothing but printing a warning, that these functions are gone. This is
done to allow plugins to catch up.
- Some bugfixes in XML saving are included, they simply were in the
file.
Original commit message from CVS:
Added a first stab at a better clocking system.
It still needs more infrastructure for async notification and custom clock
implementors.
This thing can still deadlock the pipeline.
Original commit message from CVS:
miscellaneous fixes, added gst_pad_unset_sched() api.
although I unref the old pipeline and the cothread context gets freed in dynamic-pipeline.c,
I still get segfaults.
Original commit message from CVS:
* cleaning up duplicated code in gstbin.c
* added some sanity checks in gstpad.c
* added checks for failed connections in gstparse.c
* better docs in gstxml.c
Original commit message from CVS:
summary: fix xml in gstreamer
1) make clear distinction between loading xml that actually creates objects and loading xml that just
synchronizes properties with objects. moved most of gst_element_restore_thyself functionality to
gst_xml_make_element. this new function name can change if it sucks.
2) many various fixes. createxml and runxml work now.
3) doc updates.
4) GstSignalObject is stil broken. i have no idea what it's supposed to do.
Original commit message from CVS:
Better, cleaner state management of the scheduler by adding scheduler state
flags.
typefind has to interrupt instead of yield.
Fix a leak in the queue when it's dropping buffers.
Original commit message from CVS:
This is an attempt at not segfaulting on errors but reporting some
usefull info instead.
- bin changes so errors can propagate.
- changed the _FAST macros to _CAST because that is what they do.
- removed all references to cothreads out of the core, they are
really a scheduler issue, handler with a sched_private gpointer.
- added a live buffer count, for debugging buffer leaks.
- added error checking in gst_scheduler_state_transition this solves the
"out of cothreads" problem.
- GST_ELEMENT_NO_ENTRY == GST_ELEMENT_INFINITE_LOOP
- added 2 private element flasg for use by the scheduler
(_COTHREAD_STOPPING) is now
- added scheduler entry points:
- _yield : to create possible scheduling points.
- _interrupt: to stop execution of an element.
- _error: to signal en error condition to the scheduler.
- improved error messages for pads.
- signal gst_element_error where appropriate.
- added the a new bin to the parent before entering it so one can reference
its children.
- queue memleak fixes on dispose.
- added possible deadlock detection in queue (turned off be default)
- GstBasicScheduler is a real class of its own now, hiding its internal
variables.
- GST_ELEMENT_IS_COTHREAD_STOPPING is gone. either call explicit _yield
operations, or make a sane loop.
- Better state change handling in filesrc. Better error reporting/recovery
too.
- updated core plugins.
- detect non decoupled elements on scheduler boundries and error.
Original commit message from CVS:
- Reclaim cothread state even if the cothread was never activated after
the free.
- fix the bin state change when there are no more children.
- use a real method to signal the parent bin of a state change.
- move the state change policy in the scheduler.
- remove the unused and ridiculous state change event
- don't free the cothread state when the element is disabled. only free it
when the element is removed from the scheduler.
Original commit message from CVS:
Some more work on cleanup.
- added two functions in the scheduler _setup and _reset to initialize
the context. In the case of the cothread context we have to map the
cothread stack space onto the threads stack.
- setup/reset the scheduler context in the threads context.
- fix the ghostpad cleanup.
- slightly changed the scheduler code to cleanly remove connections.
Original commit message from CVS:
- Elements can now send events to their parent.
- remove the g_signals from the core for parent<->child communication
- the application can easily get element info by listening for an event
signal from the toplevel bin.
- added gst_element_info()/_error().
- fakesrc and fakesink use the info event instead of g_print.
- GST_TYPE_* causes segfaults with elect fence, rever to G_TYPE_POINTER
until we know what's wrong.
- various leaks fixed wrt element destroy.
- The object that created the event is now stored as GST_EVENT_SRC
Original commit message from CVS:
- added playondemand plugin by Leif Morgan Johnson <lmjohns3@eos.ncsu.edu>
- some fixes to int2float
- aplied a patch from wrobell <wrobell@ite.pl> that is a first attempt at
making automake 1.5 happy (gst now requires automake1.5). It's still not
perfect but it builds.
- Made the schedulers plugable. The default scheduler now lives inside a
plugin.
- Added a new mpeg1/2 parser/demuxer.
- Fixed some compiler warnings in the core libs.
- substantial work to GstThread (hopefully less race conditions). simplified
the code in GstThread a bit. A state change can now also happen in the
thread context.
- reworked the state semantics of a bin. it'll now automatically get the
highest state of its children.
- the autoplugger now nests the threads so that a state change failure of
one thread doesn't make its upstream thread lock.
- GstQueue refuses to go to PLAYING if the sinkpad is not connected. This
way the queue will not wedge in the _get lock.
- GstQueue unlocks its mutexes when going to PAUSED.
- make sure that when all elements in a bin/thread go to PAUSED, the bin
is set to PAUSED too.
- make a parent bin wait for its children to PAUSE before ending the
iteration with FALSE (EOS)
- Some changes to GstPlay to deal with EOS.
- aplied the latest patch from Zeenix to gstrtp.
end result: GstPlay doesn't crash on EOS and the pipeline is now shut down
properly.
Original commit message from CVS:
API docs.
revived _buffer_ref_by_count
fast types for scheduler and bin.
error checking on plugin features;
removed some prototypes that were not implemented (gst_pipeline_iterate
comes to mind)
remove gst_pad_event until we know what it's supposed to do.
remove sinesrc, it wasn't compiles anymore, so...
updates to various elements that used the old event API.
Original commit message from CVS:
1. Add more warnings for the gst core only. Various trival fixes
to quiet the warnings.
2. Fix GstBufferCopyFunc prototype.
3. Re-apply the reverted type!=0 assertion in gst_elementfactory_new.
