Original commit message from CVS:
initial checkin for the deep_notify signal which replaces INFO events in the long run.
PLEASE do not use gst_element_[info,message,error] anymore. Use g_object_notify instead.
Thank you.
Original commit message from CVS:
this fix makes sure that we actually request a pad from the template with
an unused name
this isn't optimal but gets the job done
should we move this code fragment to it's own helper function to use
everywhere stuff is requested according to a template ?
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:
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:
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:
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:
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:
- 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:
* minor typographical change to autogen
* added --with-html-dir option to configure
* more robust docbook checks
* convert to standard docbook makefiles, at least for the gst/ directory
* added filesrc.h so that docbook can know about filesrc
* updated -sections.txt because docbook is incredibly stupid and requires that at
least one of the lines between <section> and </section> is not an entity
* first pass at possible getting the docs to build on glib2, untested
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:
all info to describe a dparam is now in the GstDParamSpec struct. The resemblance to LADSPA descriptors is intentional
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:
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:
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:
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:
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:
Convert XMMS and LIBGHTTP checks to use GST_CHECK_FEATURE()
XMMS check is turned off by default (though not in a very neat way)
Original commit message from CVS:
Changed a stupid assert in request_pad.
Some fixes for pullregion and EOS conditions.
Remove an unneeded check in the scheduler (check for NULL buffer)
some EOS fixes for pullregion in disksrc.
Removed the macro in the gstparse.h header 'cause it's internal to gstparse.c
Added a check in gstparse for NULL element.
Original commit message from CVS:
Added some caps != NULL checks.
Patched up a problem with the thread handling when the iteration fails.
Cleaned up the output of -inspect a tiny bit.
Original commit message from CVS:
Collection of minor changes:
* autogen.sh - remove config.cache before running ./configure
* gst/elements/gstfakesink.c - print out the size of the buffer, too
* plugins/Makefile.am - removed a spare trailing backslash
* plugins/arts/gst_artsio_impl.cc - change the scale back to 0.5
* plugins/oss/gstosssrc.c - change name slightly to match osssink
Original commit message from CVS:
API docs updates.
Properly implemented the disksink.
Fixed a compile problem with alsa.
Added bufferpool handling to dvdec
Some compiler warning fixes
Original commit message from CVS:
* first stab at a disk sink element
* no optimization, is it necessary ?
* basic error checking
* seems to work; you can copy files by typing
gstreamer-launch disksrc location=test.in ! disksink location=test.out
* decode of mp3 to raw pcm also tested
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:
Lots of updates to the plugins for caps negotiation.
Added YUY2 output to the win32 dlls.
Added a colorspace converter in gstplay
Original commit message from CVS:
Modified a lot of plugins to use the caps system.
Modified the caps of audio/raw to our agreed properties.
Added the multidisksrc plugin of Dominic Ludlam
Renamed audiosink/src to osssink/src and updated all the examples using
the old name. Moved oss specific plugins in an oss directory. removed
the old audiosink from the elements/ dir.
removed audioraw.h metadata header files since we now use the properties.
There are still a few plugins that won't build because they include the
old audioraw.h header file. This will be fixed soon.
Make sure the caps are set in the plugins as described by their
padtemplates (this should solve problems with gstmediaplay with various
media files).
*please don't panic when some plugins won't build, just cd manually into
the plugin dirs* This will be fixed soon.
Original commit message from CVS:
More work on capsnego proxying. It should be OK now.
Added another testcase enum that shows various capsnego algorithms.
Warn about pads that try to set a capability incompatible with their
padtemplate.
Implemented refcounting and copy_on_write for caps/props.
Original commit message from CVS:
More work on capsnego, mostly proxying
Added another testsuite for capsnego
Added caps to vorbisdec, mp3parse, mp1videoparse
Redid the queue proxy handling a bit.
Original commit message from CVS:
Reworked the capsnegotiation function
audiosink now uses capsnego to set its parameters
mpg123/ac3dec use capsnego instead of metadata
Added the beginnings of a testsuite for capsnego.
Original commit message from CVS:
Reworked getregion/pullregion stuff. Region is now specified by a type
(OFFSET_LEN, TIME_LEN, etc.) and two guint64's. They are offset and len,
where offset can be used for the time field, and len would be zero or
the time unit (say, 33ms for video).
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.
Original commit message from CVS:
Docs updates
Added XML load from memory functionality
Undid the videosink patch, something else is wrong now on my machine:
no MMX acceleration :-(
Original commit message from CVS:
Applied the patch from Sepp Wijnands <mrrazz@garbage-coderz.net> that solves
the 'OSS hangs when opening the device when in use' bug.
Original commit message from CVS:
More EOS changes.
When a bin2 is found inside a bin1, we add the bin2 to the EOS providers
of the bin1. When there is nothing more to schedule in bin1 and bin2 has
fired EOS, bin1 is in EOS.
The queue overrides the EOS notification and calls EOS on the src pad
when the queue is empty and the sink pad is in EOS.
Original commit message from CVS:
Added mthodes to request an element to create pads: gst_element_request_pad*
This can be used to construct a tee and a muxer/mixer/aggregator element.
Moved the tee element to elements/ because it can now be handled with the
new pad request features.
The padfactory also has some changes: a pad can now be of presence REQUEST,
which means that the pad can be requested from this plugin (doh).
Original commit message from CVS:
Massive build fixup. Will send message to -devel list later with details
on the changes and what they mean for Makefile.am writers. Check
docs/random/omega/build/TODO for a list of things that I had to make sure
of.
NOTE: this requires a complete rebuild of all plugins, since I also
changed the STATE enum to a bitfield instead of sequential numbers.
Original commit message from CVS:
Added an extra signal_cond to queue to make sure that the waiting thread
is woken up. Can somebody with queue problems verifify that this does
improve the situation a bit. I'm suspecting that something else is going
on, like a pthreads bug or something.
Small updates to the fake elements.
Original commit message from CVS:
Updated the manual and the docs.
Removed the esdsink in gst/elements/ we have a real one not in the
plugins dir.
Added more APIs to query the plugins, types and caps. more fields now
have a getter and a setter. This is needed to make gstreamer wrapper
fiendly.
Added gst_element_disconnect beacuse we also have a gst_element_connect
Original commit message from CVS:
Rearranged cothreads sources a bit, added some API docs.
Added some functions needed for gstreamer-inspect.
Added num_sources to fakesink.
Original commit message from CVS:
Added a check for libjpeg
Added and action for the load menu in gstplay
Fixed drag and drop in gstplay
More verbose errors in gstasyndisksrc
Original commit message from CVS:
Massive, massive update of most source files. I went through and cleaned
up all the warnings that I could, which involved fixing some of the plugins.
The configure.in script was re-arranged and cleaned up so, and a check for
libtool 1.3.5 was added to autogen.sh. Added checks for Gtk and GNOME.
Some plugins were removed from the list of things to build for various reasons.
Added GST_DEBUG_FORCE_DISABLE in gstgetbits, since that's time critical and
even an if() from a DEBUG can significantly increase runtimes.
