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>
* gst/gstdata.c (gst_data_is_writable): s/>=/>/. If there is only
one refcount, the calling function is the owner of the buffer.

(gst_pad_link_free), (gst_pad_link_try), (_invent_event),
(gst_pad_pull):
implement enforcing discont events before buffers are passed. This
allows state changes of only some elements and later correctly going

GST_ELEMENT_QUERY_TYPE_FUNCTION(), GST_ELEMENT_EVENT_MASK_FUNCTION().
These are our last variadic macros that can't be replaced with
inlines. Celebrate! Also fix a typo in an #ifdef that was
attempting to deprecate gst_element_clock_wait().

functions. Add new is_negotiated() function.
* gst/gststructure.c: (gst_structure_copy):

weeks ago. _copy() returned the argument, not the new copy.
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:
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:
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:
- 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

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.

- 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:
Some more event flags
some more padquery types
Better debugging in _pad_get_caps
ref the caps before adding them to a padtemplate
Original commit message from CVS:
- some pad.h reorg, better grouping of function
- added methods and default implementations to get supported formats,
seek methods/flags and query types.
- implemented pad activation/disabling
- start negotiation in the READY->PAUSED state
- added GST_PAD_IS_USABLE (better name?) to check if a pad can be used
for data transport (check if connected and peerpad is active)
- added query for segment end
Original commit message from CVS:
- Removed bufferpool code and move that to gstbuffer.c
- implemented refcounting on GstData
- implemented new buffer code based on Company's work in the EVENTS2 branch
- added boxed types for GstData/GstEvent/GstBuffer/GstBufferPool
- added refcounting to bufferpools and events
- use lockfree allocation for buffers
- simplified the clock, use lockfree allocation
- use GQueue in GstQueue for faster access to the tail element

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.
- added release_locks to gstelement so that the element can unlock itself
- added some more predefined events.
- added folowing functions to gstpad:
- convert function: get the relation between formats on this pad
- query function: get stats about the pad (position/total/latency)
- internal connect function: find out how this pad connects to other
pad internally to the element.
- generic pad_dispatcher.
- removed the last bits of pullregion
- use release_locks on the queue.
- added some events to queue
- make gstthread use the new release_locks function
- make the scheduler use the new clock_wait functions
- added events to fakesink
- added query functions to filesrc
- swap type and offset in the bytestream seek API to match fseek
- added some event handling in bytestream.
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:
- Remove the propsprivate header file
- Added new API for properties.
- Moved the clock distribution to the scheduler.

- some scheduler cleanups.
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:
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:
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:
- 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:
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:
- 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.
Original commit message from CVS:
Nobody checks the return value of gst_pad_connect. This patch
renames gst_pad_connect to gst_pad_try_connect and makes
gst_pad_connect return void.
Original commit message from CVS:
Updated the event system to use event,timestamp,data instead of a pointer.
Updated elements to use the event system correctly.
Changed "size" to "filesize" in disksrc.
Original commit message from CVS:
Added prototypes for gst_pad_peek, gst_pad_select and gst_pad_selectv.
Added different scheduling methods in aggregator.
Fixed a bug in fakesrc when setting up the scheduling functions.
