Revert bogus caps template check in pad linking, pad caps
are important when linking not the template, which is more
general than the current caps.

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.
Added GstBus for mainloop integration.
Added GstMessage for sending notifications on the bus.
Added GstTask as an abstraction for pipeline entry points.
Removed GstThread.
Removed Schedulers.

Added STREAM_LOCK and PREROLL_LOCK in GstPad.
Added pad blocking functions.
Reworked scheduling functions in GstPad to prepare for
scheduling updates soon.
Moved events out of data stream.
Simplified GstEvent types.
Added return values to push/pull.
Removed clocking from GstElement.
Added prototypes for state change function for next merge.

get-based pad (#150546).
Original commit message from CVS:
* gst/gstpad.c: (gst_pad_query):
Do query on realized pad, similar to how convert/send_event handle
this. Also makes sense, since this pad belongs to the function to
which this query will be sent. Fixes#158163.
Original commit message from CVS:
* gst/gstpad.c: (gst_pad_is_negotiated),

it doesn't actually check the contents), so be sure to hand it
a RealPad else we'll crash.

Original commit message from CVS:
2004-07-14 Andy Wingo <wingo@pobox.com>
* gst/gsttag.c: Add a tag merge func for pointers. The header was
there all along, but the function wasn't. (guile-gstreamer's build
system uses the address of the function -- I wasn't actually
trying to use this.)
2004-07-13 Andy Wingo <wingo@pobox.com>
* gst/gstpad.c (gst_pad_try_set_caps): Naive link functions (such
as gst_pad_proxy_pad_link) just link to every other pad when they
are called. In the case where the graph has cycles, this will mean
that a call to try_set_caps will recurse. Allow this recursion
and return OK, while we wait for the first try_set_caps to give a
proper return value.
(gst_pad_link_call_link_functions): Since this function is the
only one to set the NEGOTIATING flag on a pad, if the flag is set
it means that the link functions have indirectly recursed. If this
happens, error out to avoid infinite recursion and an eventual
SEGV.
(gst_real_pad_class_init): Remove a crufty GtkObject comment.
(gst_pad_proxy_getcaps): Intersect the result with the template
caps to ensure that the return value is valid.
2004-07-11 Andy Wingo <wingo@pobox.com>

Original commit message from CVS:
* gst/gstpad.c: (gst_pad_check_schedulers),
(gst_pad_can_link_filtered), (gst_pad_link_filtered),
(gst_pad_link_prepare):
check that pads that get linked belong to the same manager. The old
code allowed linking elements before putting them into bins, so it
worked to link them and then put them in different threads, which
lead to weird behaviour.
Since this effectively disallows linking elements before putting
them in a bin, some applications might not work after this and error
out. If these applications are too critical, we might need to revert
that patch. Please test this before the next release...

Original commit message from CVS:
2004-02-24 Andy Wingo <wingo@pobox.com>
* gst/gstelement.c (gst_element_dispose): Protect against multiple
invocations.
* gst/schedulers/gstoptimalscheduler.c
I added a mess of prototypes at the top of the file by way of
documentation. Some of the operations on chains and groups were
re-organized.
(create_group): Added a type argument so if the group is enabled,
the setup_group_scheduler knows what to do.
(group_elements): Added a type argument here, too, to be passed on
to create_group.
(group_element_set_enabled): If an unlinked PLAYING element is
added to a bin, we have to create a new group to hold the element,
and this function will be called before the group is added to the
chain. Thus we have a valid case for group->chain==NULL. Instead
of calling chain_group_set_enabled, just set the flag on the group
(the chain's status will be set when the group is added to it).
(gst_opt_scheduler_state_transition, chain_group_set_enabled):
Setup the group scheduler when the group is enabled, not
specifically when an element goes PAUSED->PLAYING. This means
PLAYING elements can be added, linked, and scheduled into a
PLAYING pipeline, as was intended.
(add_to_group): Don't ref the group twice. I don't know when this
double-ref got in here. Removing it has the potential to cause
segfaults if other parts of the scheduler are buggy. If you find
that the scheduler is segfaulting for you, put in an extra ref
here and see if that hacks over the underlying issue. Of course,
then find out what code is unreffing a group it doesn't own...
(create_group): Make the extra refcount floating, and remove it
after adding the element. This means that...
(unref_group): Destroy when the refcount reaches 0, not 1, like
every other refcounted object in the known universe.
(remove_from_group): When a group becomes empty, set it to be not
active, and remove it from its chain. Don't unref it again,
there's no floating reference any more.
(destroy_group): We have to remove the group from the chain in
remove_from_group (rather than here) to break refcounting cycles
(the chain always has a ref on the group). So assert that
group->chain==NULL.
(ref_group_by_count): Removed, it was commented out anyway.
(merge_chains): Use the remove_from_chain and add_to_chain
primitives to do the reparenting, instead of rolling our own
implementation.
(add_to_chain): The first non-disabled group in the chain's group
list will be the entry point for the chain. Because buffers can
accumulate in loop elements' peer bufpens, we preferentially
schedule loop groups before get groups to avoid unnecessary
execution of get-based groups when the bufpens are already full.

by new pad negotiation. Add some debugging, and fix logic bug in gstpad.c.
Original commit message from CVS:
Add some sanity tests to gstpad.c. Check that pad is linked before
calling gst_pad_try_set_caps() on it in spideridentity.
Original commit message from CVS:
* gst/elements/gstaggregator.c:
* gst/elements/gsttee.c:
Use gst_pad_proxy_getcaps().
* gst/gstpad.c:
* gst/gstpad.h:
Add gst_pad_proxy_getcaps(), which filter elements can use
as a generic getcaps implementation.
Fix gst_pad_get_allowed_caps(). It just wasn't doing what
was advertised.
Original commit message from CVS:
* gst/gstpad.c:
Rearrange/rewrite much of the pad negotiation code, since it
resembled pasta. This actually changes the way some
negotiation works, since the previous code was inconsistent
depending on how it was invoked. Add (internal) structure
GstPadLink, which is used to hold some information (more in
the future) about the link between two pads. Fixes a number
of bugs, including random lossage of filter caps when the
initial negotiation is delayed. A few functions are still
unimplemented.
* gst/gstpad.h:
Add GST_PAD_LINK_{SUCESSFUL|FAILED}() macros. Please use
these when testing GstPadLinkReturn values instead of comparing
directly.
Original commit message from CVS:
merge TYPEFIND branch. Major changes:
- totally reworked type(find) system
- bytestream is out of the core again
- typefind element is now part of gstelements
Original commit message from CVS:
s/GstBuffer/GstData/ in the API where you can pass events. Fix the plugins to deal with that. Fixes#113488. Also includes scheduler patches, and probably fixes some queue bugs relating to events and buffers.
Original commit message from CVS:
implement translatable error messages using gerror.
Includes bugfixes for:
- crash when unlinking Ghostpads
- make *_PAD_* macros use glib casts
- make spider typefinding merge buffers correctly
Original commit message from CVS:
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:
Fix aliasing problems noticed by gcc-3.3. Suggests that we need to
change gst_pad_{push|pull}() to GstData *. (and probably others)
Original commit message from CVS:
implement proper refcounting of pad's templates and references from real pads to their ghost pads and the other way around - this fixes the segfaults in the player
Original commit message from CVS:
Added a simple function gst_pad_recover_caps_error that a plugin
should call from now on (instead of gst_element_error). This function
will emit a caps_nego_failed signal that the app can catch to resolve
the negotiation failure.
Original commit message from CVS:
general fixes:
- changed newly added locked_state API to work like GStreamer does
- added gst_element_sync_state_with_parent function
- revert: pad linking does not require non-playing state
- updated spider and pipeline parsing to link elements in playing state
- bugfix: pads are now activated when added to a playing element (broke above change)
Original commit message from CVS:
- Use the eventhandler instead of the event function to send events.
- make the scheduler setup the eventhandlers
- intercept flush events on pads links that can potentially queue data
and flush it.
- some more debugging info in spider.
I can think of one case where this flush might fail: unconnected pads where
the scheduler has not set up the eventhandler yet. I'll come up with a
solution for that soon.
Original commit message from CVS:
- implement FLOATING flag on caps/props
- use gstmemchunk for caps/props
- implement remove_entry for props
- various refcounting functions
- fix refcounting on caps/props
- use tracing for caps/props/propsentries
- fix memleak in transform functions
- fix refcounting on elementfactory padtemplates
- add dispose for padtemplates
- shortcut pad negotiation early on
Original commit message from CVS:
Provide intrastructure to not have to pass NULL buffers on errors and
interrupts, this should fix some issues with the optimal scheduler.
Original commit message from CVS:
- Added PAD_NEGOTIATING flag, remove PAD_EOS flag
- Try to avoid negotiation in state change if pad were already negotiating
- Added gstquery.c for completeness (maybe merge common functions with
gstformat.c?)
Original commit message from CVS:
- major API breakage (one of the last, I promise...)
- GST_PAD_QUERY -> GST_QUERY
- GstPadQuery -> GstQuery
- Move query definitions to gstquery.h to allow for future dynamic
query types.
- remove _pad_handles_* in favour of extra format/event functions to
make the same checks.
- fix elements
- Implemented missing query/event/formats functions in gstelement
Original commit message from CVS:
- disable pads when going to PAUSED, we want to make sure no data is
passing when an element is not PLAYING.
- changed the clock sync API, element should now get a ClockID first and
sync on that. This makes it possible to cancel clock requests.
Original commit message from CVS:
- Added caps as a property
- Removed signals in favour of property notification
- Use probes instead of event_received signal
- Small cleanups
Original commit message from CVS:
- some cleanups
- revert a patch that needs more thinking..
- move common code and sanity checks in gstscheduler.c instead of the
real schedulers.
- remove sanity checks from the schedulers
Original commit message from CVS:
- Make the return GList of gst_element_get_pad_list as const
- Pad scheduler refactoring
- Remove gst_pad_set/unset_scheduler as it's not needed
- Reimplement gst_pad_get_scheduler using the parent scheduler
- Remove gst_pad_peek as it cannot work reliably
- Remove the pad bufpen, replace with scheduler private gpointer
- Make queue use the new _get_scheduler implementation
- Remove _pad_unset_scheduler from GstScheduler
- Remove LOOP_SEEK mode from aggregator
- Other fixes for API changes.
Original commit message from CVS:
This changes an important part of the plugin API, gst_pad_try_set_caps() no longer returns a boolean, it now returns a GstPadConnectReturn, which makes much more sense than a boolean. All plugins have also been changed, so don't worry ;)
Original commit message from CVS:
big ass set of useless dog fixes [1]
changes to pad code so that NULL names are allowed and useful [1]
some API changes [2]
lots of code cleanup
[1] approved by wtay [3]
[2] approved by wingo
[3] how long can we keep blaming that code guy that's not back from holidays
yet for everything we commit ?
Original commit message from CVS:
fixes bug
http://bugzilla.gnome.org/show_bug.cgi?id=90333
and similar.
I'd like to also do s/guchar/gchar/ in the xml functions, any reason not to ?
please comment ;)

Original commit message from CVS:
if you can't write to the registry (ie it is root-owned and you are user) and it
is out of date, just ignore it; plugin state will get written to the user reg
Original commit message from CVS:
- The clock_wait now returns the difference between requested time and
unlock time.
- Misc defines like GST_SECOND in gstclock.h
- remove pre/post in gstelement.c until fixed.

docs/random/wingo/threadsafe-properties
* some cleanups
* this change will cause binary incompatibilities, better rebuild them plugins
now, off to drink :-)
Original commit message from CVS:
Totally rewritten registry handling.
- move the registry save/load code into a gstregistry subclass, this
will make it possible to use other registries (flat file, web based,
RDBMS type, etc..)
- a simple GMarkup xml registry is implemented
- use standard statically linked plugins for core elements.
- GstPlugin has a very well defined set of functions now
A little bytestream hack..
Added more info to -inspect.
Some more debugging info for clocking.
Small cleanups
I use ./gst-register --gst-plugin-path=/opt/src/sourceforge/gst-plugins/gst-libs:/opt/src/sourceforge/gst-plugins/
to register core and gst-plugins now.
Original commit message from CVS:
commit to make gstreamer follow the gtk function/macro naming conventions:
GstPadTemplate <-> gst_pad_template <-> GST_PAD_TEMPLATE
and the same for *factory and typefind.
Original commit message from CVS:
* add notify back to filesrc, it's needed for MVC applications
* remove notify printouts from gst-launch
* cleanup in gst-plugins configure.ac

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

* added pkg-config stuff for the editor's libs
Original commit message from CVS:
* document gst_caps_debug
* change gst_caps_debug to accept a label argument, assists greatly
in debugging capsnego
* better names from gst_object_name_default
* some more debugging in gstpad.c
* require caps to match padtemplates on both side of a connection
* gstspider uses default naming so that names are globally unique
* moved filesrc offset arg to the top -- show up first in a prop list.
in the future we should have flags on props indicating which ones
it might be interesting for the end-user to change.
* initialize cothreads in the more standard way, and provide some more debugging
Original commit message from CVS:
* a warning fix
* a potential commenting error fix
* more debug output when trying to set caps so I can actually tell from it
what's going on
Original commit message from CVS:
Fixed some warnings
Always recalculate caps intersection in perform_negotiate 'cause they
might have changed. (needs better solution probably)
Original commit message from CVS:
* many fixes related to dynamic pipelines.
* addition of gst_element_disconnect_elements(), as per connect_elements()
* don't have a cow if typefind changes state in its signal handlers
* support of request pad -> request pad in connect_elements()
* some fixes in int2float that will eventually need to be ported to float2int and
adder
the gstelement api is getting bloated, expect a rewrite within the next month.
Original commit message from CVS:
Delay pad negotiation until the element is in READY or higher. this will
gice the element a chance to open its devices before we start calling the
connect functions.
Make sure we use the real pad in the negotiation.
Some other small cleanups.
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:
Landed the new improved capsnegotiation system.
The main idea is to keep track of the possible data types that can
pass through a connection. plugins can at any time inspect, adjust and
refine these caps. plugins also get notified when something changes to
the types so that they can reconfigure themselves.
Look at the updated plugins and the soon to be finished doc.
Original commit message from CVS:
- Removed deprecated buffer flags.
- removed gst_element_signal_eos, replaced with gst_element_set_eos
to set the object to PAUSED, signal an eos event etc..
- small updates to documentation
- repair some plugins
Original commit message from CVS:
- Added a function to get the currently executing cothread
- Removed some useless includes
- _interrupt now returns a boolean so the behaviour after the interrupt
can be controlled by the scheduler.
- Added a better way to set/get the default scheduler.
- make thread and pipeline get the default scheduler.
Original commit message from CVS:
Tee Fixes.
added cothread_stop (not used)
improved the pad event dispatcher.
added an event_received signal on the pad.
do less state changes in the autoplugger.
small scheduler fix.
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:
cothread cleanup.
- removed some old code.
- ran the thing through indent
- rename cothread_init/free to cothread_context_init/free
- implement cothread_free/destroy to clear the cothread_state slot
- make cothread_init reuse empty slots.
minor cleanups in error reporting (gstpad, gstelement)
code cleanup in gstthread
make unexpected state changes in gstthread less fatal
free the cothread_state in the scheduler.
This one passes all the current cvs testcases including dynamic-pipeline.
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
