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:
some compile fixes, api changes, and i added the ability to create new chunks on the
stack, which can extend the main thread's stack up to 8M under linuxthreads. thanks
to billh for the {set,get}rlimit tip.
on the other hand, there's a nasty bug in cothreads when they are run without gthreads
that i'm still tracking down. that's the last bug though, at this point.
the commit is to syn the repository with my working copy before moving cothreads to a
separate module.
Original commit message from CVS:
Change soversion back to 0:0:0 and add use of -release flag for libtool.
This means that any program linking against libgst will automatically have
the specific release of libgst encoded into it. This enforces the fact
that (for the moment), the API/ABI is changing rapidly enough that you
can't link against 0.3.2 originally and have it still work with 0.3.3. It
might be possible, but highly unlikely.
When we get closer to a stable API/ABI, in the 0.5.0 timeframe most likely,
we will start using soversions as recommended in the libtool docs. Then
we have to pay more attention to forward and backwards compatiblity, or
rather, we have to *start* paying attention <g>
Original commit message from CVS:
fixed a number of bugs, added support for cothread-private data and
functions of the form void (*func) (int argc, void **argv)
the test app demonstrates the thread-safety of the cothreads lib
this is shaping up to be pretty solid.
Original commit message from CVS:
* a first pass at cleaning up the configure stuff
* new cothread library started, some experimental stack allocation code is in place
Original commit message from CVS:
should fix an error in a no-glib2 error message, an error in libxml stuff
(newer versions of libxml1 can be included as libxml/parser.h), and silencing
a warning in the cothreads stuff
Original commit message from CVS:
new, shiny hack uses mutexes to determine the current pthread_descr
without resorting to internal header files. muahaha ;)
this is only for linuxthreads, of course.
Original commit message from CVS:
added a test for pth and pthreads. in summary, it doesn't work because
in __pthread_find_self() some funny stack pointer math is done that
will result in no matches for __pthread_find_self(). this is dereferenced in
__errno_location, causing a segfault on context switch because of the errno-swapping
on the part of pth. it's a mess and i don't know how to get around it. i'll
have to look into what ngpt does for looking up errno, as it has kernel threads as
well as user threads.
Original commit message from CVS:
The core code from pth has been taken out and included in gstreamer.
This code is documented, more or less, in http://www-124.ibm.com/pthreads/docs/rse-pmt.ps.
This code is designed to replace cothreads.[ch], eventually.
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:
Previously filesrc would segfault when fed with the name of a directory.
Added check to ensure that the given file is a regular file.
Original commit message from CVS:
* fix doc build for glib2
* remove template files from cvs, they are generated with gtkdoc-mktmpl
* new, cleaner interface to the parser facilities
* cleanups in gstparse.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:
* s/filter/plugin/
* add $(GST_LIBS) to all plugins
* move Makefile.am things around to a mostly standard layout
* remove HTTP flags/libs from elements since http element moved
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:
added function gst_xml_write_file() which writes a nicely formatted and indented
xml representation of an element to a file. you can use stdout or stderr, for
example.
Original commit message from CVS:
fixes for make distcheck
does GST_ELEMENT_IS_COTHREAD_STOPPING still exist ?
and if so, how should it be found by the bytestream test ?
Original commit message from CVS:
fixes to make distcheck work
changed registry out of date to warning to allow tests to continue regardless (any better suggestions much appreciated)
Original commit message from CVS:
Some small cleanups.
added a drop_probaility arg to identity, so it occasionally can drop buffers
to simulate network packet loss
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:
* save the plugin paths in the registry
* load them back
* don't look in PLUGIN_DIR ($prefix/lib/gst usually) when PLUGIN_BUILD_DIR
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:
- 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:
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

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:
quoting from the comment i put in gststaticautoplug.c:
it is likely that the plugin is not loaded yet. thus when it loads it
will replace the elementfactory that gst built from the cache, and the
GST_OBJECT_NAME will no longer be valid. thus we must g_strdup its name.
this might be an implementation problem, i don't know, if a program keeps
a reference to a cached factory after a factory has been added on plugin
initialization. i really don't know though.
Original commit message from CVS:
* cleaned up mangling of properties and names in ladspa by using g_strcanon
* added g_strcanon to gobject2gtk.[ch], not tested though
Original commit message from CVS:
Direct events to the event handler for non event-ware elements.
pass the event to the chain function for event aware elements.
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:
remove ability to set dparams from -launch. this is the only real loss of functionality from moving dparams out of core. Maybe I'll make the parser pluggable ;)
Original commit message from CVS:
all info to describe a dparam is now in the GstDParamSpec struct. The resemblance to LADSPA descriptors is intentional
Original commit message from CVS:
Move newbuf creation to the non-copyfunc case, since the copyfunc is now
assumed to create the buffer (from a bufferpool, perhaps). This solves a
memory leak.
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:
added to -launch syntax: if an arg is prefixed with a '@' it will be treated as a dparam. eg sinesrc @volume=1.0 @freq=440.0
Original commit message from CVS:
gstinfo.[ch], cothreads.c: added initial support for -finstrument_functions
gstbin.c: removed a reference to config.h
gstbuffer.[ch]: added gst_buffer_is_span_fast(), used it in gst_buffer_span
elements/gstfilesrc.c: initial work fleshing out the event handling code
everywhere else: wrapped XML stuff in #ifndef's
Original commit message from CVS:
replace GstDparamPoint struct with GValue** (actually that was in the previous commit). Change gst_dparam_new_point to gst_dparam_new_value_array
Original commit message from CVS:
s/Dparam/DParam/ <taaz> i'll whine about an irrelevant thing: Dparam vs DParam. though Dparam is more consistantly screwed up with everything else ;)
Original commit message from CVS:
Added MIPS support to cothreads (untested), and moved all the architecture-
specific code out of the many header files and put them all in gstarch.h.
Original commit message from CVS:
I think I finally have this configdir thing under control. The defines on the
make command lines were not following the GST_CONFIG_DIR variable.
Original commit message from CVS:
The bufferpool api has changed. Check gstbufferpool.h to see the updated
interface.
Also, the default bufferpool implementation has been finished somewhat. Take a
look at speed.c to see an example of its use, when I get the plugins committed.
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:
Lots of modifications to the plugin system.
- Added a GstPluginfeature object that serves as a base class for all
plugin contents.
- changed the plugin API, everyhting is now added with
gst_plugin_add_feature
- typefactories are named now so that they can be located easily and filled
in at plugin load.
- mime types like "video/raw image/raw" are gone for now.
- lots of plugin updates (style and API changes)
- tested with an without registry.
- updates to various tools.
- added a little testsuite to test/show how you can load plugins (4 modes)
Test this one, Almost everything has changed :-)
Original commit message from CVS:
- changed timestamps to gint64 (*signed* 64-bit)
- updated buf->offset handling to deal with the -1 (0xffffffff) case
- added gst_buffer_span() and gst_buffer_merge (see -devel for details)
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.
Original commit message from CVS:
Some code cleanups.
Added printouts of the buffer timestamps in identity, fakesrc, fakesink.
Added an aggregator test element.
Original commit message from CVS:
Aplied the patch from Andy Wingo <apwingo@eos.ncsu.edu> add padtemplates
to element classes without using an elementfactory.
The gst_element_add_padtemplate_to_class method was renamed to
gst_element_class_add_padtemplate to better match glib/gtk conventions.
