* gst/gstpad.c: (gst_pad_try_set_caps):
make it work with nonfixed caps.
Note that even in the nonfixed case the link function of the pad
that tries to set caps isn't called.

(gst_clock_is_active), (gst_clock_reset),
(gst_clock_handle_discont):
* gst/gstclock.h:

handle discontinuous events right with element time.
* gst/gstscheduler.c: (gst_scheduler_state_transition):
update to clocking fixes.
set clocks on elements in READY=>PAUSED. The old behaviour caused
a wrong element time on the first element that started playing.
* gst/schedulers/gstbasicscheduler.c:
(gst_basic_scheduler_class_init):
* gst/schedulers/gstoptimalscheduler.c:
(gst_opt_scheduler_class_init):

update to test new element time.
* gst/autoplug/gstspideridentity.c: (gst_spider_identity_getcaps):
use _get_allowed_caps instead of _get_caps. This catches filtered
caps correctly.

disable a test that only works sometimes.

(gst_pad_link_call_link_functions), (gst_pad_try_set_caps),
(gst_pad_set_explicit_caps), (gst_pad_get_caps):  In try_set_caps,
check new caps against existing caps -- if they're the same, return
OK without renegotiating.  caps-nego-failed signal fixed so that
the marshaller isn't VOID__OBJECT.  Also changed to G_TYPE_POINTER
to save an extra caps copy.  Don't complete negotiation if a pad
link function returns DELAYED.

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.

d7e33dd2ce - Use the eventhandler instead of the event function to send events.
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.

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.

b2ee38575d Landed the new improved capsnegotiation system.
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.

087dee1f62 This is an attempt at not segfaulting on errors but reporting some usefull info instead.
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.

- 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.

b38d9a945b A rather large patch:
Original commit message from CVS:
A rather large patch:
- changed the API for the padtemplates:
- remove the factories (array of pointers) for the padtemplates,
properties and caps. The static array was a nice idea but converting
all the property values to a gpointer was not a good idea.
float properties were not possible, and casting a gint to a pointer
is not very portable. The new API just uses the _padtemplate_new,
_caps_new and _props_new functions to create the templates.
This has the added benefit that the API is now uniform for static
and dynamic templates and that the code can be made cleaner.
- lots of cleanups in the way the capabilities are constructed (va_list)
- lots of updates for all the plugins (new API)
- docs updates (new API)
- removed the videoraw docs.

Original commit message from CVS:
This is a megapatch with the following changes:

- moved the gchar *name to GstObject, removed the ones in GstElement and
GstPad.
- moved the parent handling completely into GstObject. This cause *all* of
the plugins to fail (except those that used gst_pad_get_parent)
- rearanged the XML save handling.
- GstObject now has a class function save/restore_thyself.
- GstObject has a generic method gst_object_save_thyself, this makes it
possible to fire a signal wehever a new object is loaded. This is needed
so we can add XML save hooks.
- GstXML API has changed slightly. You now have to create a GstXML object
first before you can actually load something. This makes it possible to
attach a signal to GstXML whenever an object is loaded. I'm not sure we
will keep this interface.
- GstObject can now print the path_string without knowing about the GstPad and
GstElement types.
- Added gst_bin_get_by_name_recurse_up to lookup an element in the current
element hierarchy.
- added XML namespaces to the saved pipelines the namespace is:
http://gstreamer.net/gst-core/1.0/
namespaces are needed to distinguish user generated XML from the core XML.

Note that the plugins still contain a macro GST_OBJECT_PARENT that will be
replaced with gst_pad_get_parent shortly.

When an element fires EOS, the chain with that element is removed from
the scheduler (marked inactive). If all chains are inactive, the bin

da03fde054 WARNING: Don't grab this updated unless you're really, REALLY sure.
Original commit message from CVS:
WARNING: Don't grab this updated unless you're really, REALLY sure.
WARNING: Wait for the next one.

Whole lotta changes here, including a few random bits:

examples/*/Makefile: updated to use `libtool gcc`, not just `gcc`
gst/
gstbuffer.h: updated to new flag style
gst.c, gstdebug.h: added new debugging for function ptrs
gstpipeline.c: set type of parent_class to the class, not the object
gstthread.c: ditto
plugins/
cdparanoia/cdparanoia.c: added an argument type, updated some defaults
cobin/spindentity.c: updated to new do/while loopfunction style
mp3encode/lame/gstlame.c: argument types, whole lotta lame options
tests/: various changes

Now, for the big changes:  Once again, the scheduling system has changed.
And once again, it broke a whole bunch of things.  The gist of the change
is that there is now a function pointer for gst_pad_push and gst_pad_pull,
instead of a hard-wired function.  Well, currently they are functions, but
that's for debugging purposes only, they just call the function pointer
after spewing lots of DEBUG().

This changed the GstPad structure a bit, and the GstPad API as well.
Where elements used to provide chain() and pull() functions, they provide
chain() and get() functions. gst_pad_set_pull[region]_function has been
changed to get_pad_set_get[region]_function.  This means all the elements
out there that used to have pull functions need to be updated.  The calls
to that function have been changed in the normal elements, but the names
of the functions passed is still _pull[region](), which is an aesthetic
issue more than anything.

As for what doesn't work yet, just about anything dealing with Connections
is hosed, meaning threaded stuff won't work.  This will be fixed about 12
hours from now, after I've slept, etc.  The simplefake.c test works in
both cothreaded and chained cases, but not much else will work due to the
Connection problem.  Needless to say, don't grab this unless you *need*
these features *now*, else wait to update this stuff until tomorrow.

I'm going to sleep now.

Original commit message from CVS:
Another big set of changes.  Connections are now also pullfunc based.
gstqueue has been updated, I don't know of any other connections offhand.

There are still a few things that need doing, specifically the concept
of a source or connection with connections to multiple thread contexts is
not dealt with.  This may force us to move the threadstate from the
element to the pad, maybe keeping the element's copy for simple cases.
Then the Bin would create a structure to pass to the cothreaded _wrappers
of any such elements, which would detail the pads that are to be dealt with
by this particular cothread context.

That will speed things up to, since we don't have to look through the list
of all pads for every Src or Connection element for every iteration, we can
simply step through the list provided by the plan.  Special case might even
have a single pad pointer sitting there to trump the list, if there's only
one (the common case anyway).

Task 23098 is tracking these changes.  The main task 22588 depends on that
subtask, as well as 22240, which is a consistency check on PAD_DISABLED.

Original commit message from CVS:
Changed the way things are scheduled, especially sources.  A Src used to
have a push() function, and optionally a pushregion() to deal with async
reads, etc.  That whole thing has gone away, in favor of providing a
pull() function for the output (Src) pad instead, ala chain functions.
This makes constructing cothreaded schedules out of non-loop elements
somewhat easier.  Basically there was always a question as to which pad
was being dealt with.  In the pullregion case, cothread-specific data was
used to try to pass the region struct to the right place, which is a slow
hack.  And in general, the push function severely limited the kind of
tricks that could be played when there's more than one output pad, such as
a multi-out file reader with async capabilities on each pad independently.

This changes the way cothread scheduling occurs.  Instead of the hack to
deal with Src's by calling their push() function (or optionally the
pushregion(), in certain cases), we now are working towards a general
mechanism where pads are the only thing that are dealt with directly.

An optimization was made in the process of doing this: the loopfunction
actually run as the outer [stack] frame of the cothread is now set more
intelligently in create_plan() based on what kind of element it is.  We
now have:

loopfunc_wrapper: used for loop-based elements, it simply calls the
loopfunc in a loop, paying attention to COTHREAD_STOPPING (see
below).  It currently does other, soon to be depracated, stuff.

pullsrc_wrapper: wraps a Src that's not loop-based (since your options
are now loop- or pull-based)

There will be a couple more to deal with other cases, such as Connections
and chain-based elements.  The general idea is that it's a lot more
efficient to make the decisions once in create_plan than to keep doing
this huge if/else chain in the wrapper.  Just choose the right wrapper up
front.  It'll be most apparent performance-wise in the case of whichever
element context is switched to first for each iteration, since the whole
wrapper setup is done for every iteration.

The tricky part is that there is now a bit of overloading of the function
pointers in a pad.  The current meanings (possibly to change a bit more
soon) are:

chainfunc: as always, chainfunc pointer is mirrored between peer pads
(this may change, and the chain func may end up in pushfunc)
pushfunc: SrcPad: gst_pad_pushfunc_proxy, cothread_switch to peer
SinkPad: none (may take over chainfunc, see below) pullfunc:
SrcPad: Src or Connection's function to construct buffers
SinkPad: gst_pad_pullfunc_proxy, cothread_switch to peer

There are a number of issues remaining with the scheduling, not the least
of which is the fact that Connections are still dealt with the old way,
with _push() functions and such.  I'm trying to figure out a way to unify
the system so it makes sense.  Following the scheduling system is hard
enough, trying to change it is murder.


Another useful scheduling addition, mentioned above, is COTHREAD_STOPPING.
It's an element flag that's used to signal whatever code is running in
cothread context that it should be finishing up and exiting soon.  An
example of this is in plugins/cobin/spindentity.c.  All the loops should
now be composed of do/while loops, rather than while(1) loops:

do {
buf = gst_pad_pull(spindentity->sinkpad);
gst_pad_push(spindentity->srcpad,buf);
} while (!GST_ELEMENT_IS_COTHREAD_STOPPING(element));

The reason for this is that COTHREAD_STOPPING may be set before the above
loop ever gets started.  It wouldn't do for the body of the loop to never
once get called, that would simply stall the pipeline. Note that only the
core library code is ever responsible for setting and unsetting this flag.
All elements have to do is respond to it by cleanly exiting the loop and
the function holding it.

This is needed primarily to allow iterations to occur properly.
Basically, there's a single entry point in the cothread scheduling loop,
gst_bin_iterate_func() simply switches to this cothread.  If the element
in this context is allowed to loop infinitely, nothing would even switch
back to the context from which the iterate() was originally called.  This
is a bit of a problem.  The solution is for there to be an implicit switch
back to the originating context.  Now, even I'm not sure exactly how this
works, but if the cothread that's switched to actually returns, execution
returns back to the calling context, i.e. iterate_func().

COTHREAD_STOPPING is therefore set just before switching into this
(currently randomly chosen) context, on the assumption that it will return
promptly after finishing its duties.  The burden of clearing the flag
falls to the various wrapper functions provided by the Bin code, thus
element writers don't have to worry about doing that at all (and simply
shouldn't).


Related changes:
All the sources in elements/ have been changed to reflect the new system.


FIXMEs:
1) gstpipeline.c calls gst_src_push at some point, dunno why, it's
commented out now.
2) any other sources, including vcdsrc, dvdsrc, and v4lsrc will break
badly and need to be modified to work as pull-based sources.
