(pre_activate_switch, post_activate_switch): New stubs, things to
do before and after switching activation modes on pads.
(gst_pad_set_active): Take a boolean and not a mode, dispatch to
the pad's activate function to choose which mode to activate.
Shortcut on deactivation and call the right function directly.
(gst_pad_activate_pull): New API, (de)activates a pad in pull
mode.
(gst_pad_activate_push): New API, same for push mode.

2005-06-08 Andy Wingo <wingo@pobox.com>
* gst/gstutils.c: RPAD fixes all around.
(gst_element_link_pads): Refcounting fixes.
* tools/gst-inspect.c:
* tools/gst-xmlinspect.c:
* parse/grammar.y:
* gst/base/gsttypefindhelper.c:
* gst/base/gstbasesink.c:
* gst/gstqueue.c: RPAD fixes.
* gst/gstghostpad.h:
* gst/gstghostpad.c: New ghost pad implementation as full proxy
pads. The tricky thing is they provide both source and sink
interfaces, since they proxy the internal pad for the external
pad, and vice versa. Implement with lower-level ProxyPad objects,
with the interior proxy pad as a child of the exterior ghost pad.
Should write a doc on this.
* gst/gstpad.h: s/RPAD/PAD/, s/RealPad/Pad/.
(gst_pad_set_name, gst_pad_set_parent): Macros removed, use
gst_object API.
* gst/gstpad.c: Big changes. No more stub base GstPad, now all
pads are real pads. No ghost pads in this file. Not documenting
the myriad s/RPAD/PAD/ and REALIZE fixes.
(gst_pad_class_init): Add properties for "direction" and
"template". Both are construct-only, so they can't change during
the life of the pad. Fixes properly deriving from GstPad.
(gst_pad_custom_new, gst_pad_custom_new_from_template): Gone. For
derived objects, just set properties when creating the objects via
g_object_new.
(gst_pad_get_parent): Implement as a function, return NULL if the
parent is not an element.
(gst_pad_get_real_parent, gst_pad_add_ghost_pad)
(gst_pad_remove_ghost_pad, gst_pad_realize): Removed.
* gst/gstobject.c (gst_object_class_init): Make name a construct
property. Don't set it in the object init.
* gst/gstelement.c (gst_element_add_pad): Don't allow adding pads
with UNKNOWN direction.
(gst_element_add_ghost_pad): Remove non-orthogonal API. Replace
with gst_element_add_pad (e, gst_ghost_pad_new (name, pad)).
(gst_element_remove_pad): Remove ghost-pad special cases.
(gst_element_pads_activate): Remove rpad cruft.
* gst/gstbin.c (gst_bin_change_state): Use gst_pad_get_parent to
catch the pad's-parent-not-an-element case.
* gst/gst.h: Include gstghostpad.h.
* gst/gst.c (init_post): No more real, ghost pads.
* gst/Makefile.am: Add gstghostpad.[ch].
* check/Makefile.am:
* check/gst/gstbin.c:
* check/gst/gstghostpad.c (test_ghost_pads): Check that linking
into a bin creates ghost pads, and that the refcounts are right.
Partly moved from gstbin.c.
Original commit message from CVS:
* gst/elements/gstcapsfilter.c: (gst_capsfilter_set_property):
Free existing caps if the capsfilter changes. Add a FIXME about
setting those caps on the pads.
* gst/gstutils.c: (gst_element_get_compatible_pad), (ghost_up):
Before adding a ghost pad to a parent bin, check that there isn't
already one for the element on the bin. Prevents infinite recursion
when using decodebin in parse pipelines. Andy says he'll rewrite the
way this works anyway, so ignore the hack.

2005-06-02 Andy Wingo <wingo@pobox.com>
* gst/elements/gsttypefindelement.c (do_pull_typefind): Query the
file size, pass it on to the type find helper.
* gst/base/gstbasesrc.c (gst_basesrc_do_seek): Set the
segment_start and segment_end properly according to the seek
method. Segment_end is still a bit flaky because offset can be
negative for CUR and END cases, but it takes -1 as an "unset"
value.
Original commit message from CVS:
* gst/elements/gstidentity.c: (gst_identity_event),
(gst_identity_transform), (gst_identity_get_property):
Protect last_message property as it is accessed from
multiple threads.
Original commit message from CVS:
* gst/gstqueue.c: (gst_queue_handle_sink_event), (gst_queue_chain),
(gst_queue_loop), (gst_queue_handle_src_event):
Remove old pieces of code
Flushing the queue in an upstream event is a very bad idea.
Original commit message from CVS:
2005-05-26 Andy Wingo <wingo@pobox.com>
* gst/gstminiobject.c (gst_value_mini_object_collect): Use
gst_value_set_mini_object so as to add a ref on the object (which
will be removed when the value is unset).
* gst/elements/gstfakesink.c (gst_fakesink_class_init): Fix signal
arg type in ::handoff.
* gst/gstelement.c (gst_element_change_state): Also deactivate
pads in READY->NULL, just in case the element didn't make it to
PAUSED. Wingo tested, Wim approved.

(gst_queue_change_state):
* gst/gstqueue.h:
Fix state changes for non sinks. We now change sinks, then elements
with unconnected srcpads, then the rest.
More efficient queue unlocking in flush and state changes.
Set the pad activate mode even if it does not have an activate
function.
Original commit message from CVS:

of what was in 0.8.
* gst/gstutils.c: (gst_buffer_join):

gst_buffer_join() from 0.8.

Unref buffer when flushing in basesink.
Flush queue when going to READY
Unref buffer when _push() returns an error.
Don't free MiniObject instance when refcount is incremented
in _finalize() so that we can recover objects.

* gst/elements/gstfakesink.c (gst_fakesink_render): Er, emit with
*all* the arguments.
* gst/base/gstbasetransform.c (gst_base_transform_event): Grab the
stream lock if it's a FLUSH_DONE; normal flushes don't get the
lock (according to the docs -- if this is wrong change the docs).
* gst/gstpipeline.c (gst_pipeline_change_state): Set the bus to
flush messages in the NULL state.
* gst/gstbus.c (gst_bus_post): If a bus is flushing, unref the
message immediately and return.
(gst_bus_set_flushing): New function. If a bus is flushing, it
flushes out any queued messages and immediately unrefs new
messages. This is so when an element goes to NULL, all of the
unhandled messages coming from it can be freed, and their
references to the element dropped. In other words: message source
ref considered harmful :P
* gst/gstbin.c (gst_bin_change_state): Unref peer element when
we're finished with it.
* gst/gstmessage.c (gst_message_new_state_changed):
Original commit message from CVS:
Remove old query functions. Ported old code.
Added position/convert helper functions to gstutils.
Reordered gstpad.c code, grouping relevant things.
Remove gst_message_new(), always need to speficy a specific
message.
Original commit message from CVS:
2005-05-06 Andy Wingo <wingo@pobox.com>
* gst/gstquery.h
* gst/gstquery.c (_gst_query_initialize): Extend GstQuery from
GstData, init a memchunk.
(standard_definitions): Add a few query types, deprecate a few.
(gst_query_get_type): New proc.
(_gst_query_copy, _gst_query_free, gst_query_new): GstData
implementation.
(gst_query_new_application, gst_query_get_structure): New public
procs.
* docs/design/draft-query.txt: Removed LINKS from the query types,
because all the rest can be dispatched to other pads -- seemed
ugly to have a query that couldn't be dispatched. internal_links
is fine as a pad method.
* gst/gstpad.h: Add query2 as a pad method, add the new functions
in gstpad.c, but maintain binary compatibility for the moment.
Will fix before 0.9 is out.
* gst/gstqueryutils.c:
* gst/gstqueryutils.h: New files, implement 3 methods for each
query type: parse_query, parse_response, and set. Probably need an
allocator as well.
* gst/gst.h: Add gstquery.h and gstqueryutils.h to the list.
* gst/elements/gstfilesink.c (gst_filesink_query2):
* gst/base/gstbasesrc.c (gst_basesrc_query2): Replace old query,
query_types, and formats methods.
* gst/gstpad.c (gst_pad_query2, gst_pad_query2_default)
(gst_pad_set_query2_function): New functions.
(gst_real_pad_init): Set query2_default as the default query2
function. Basically just dispatches to internally linked pads.
Needs review!
* gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1
without using the atomic operations. Only one thread can possibly
be accessing the data at this point. Changed so as to avoid
gst_atomic operations.

* gst/gstqueue.h:
* gst/gstutils.c: (gst_element_get_compatible_pad_template),
(intersect_caps_func):
Fix gst_pad_peer_get_caps(), make it return NULL if no peer.
Always take QUEUE_LOCK after STREAM_LOCK or we might deadlock.
Some fixes for the peer_get_caps() change.
Original commit message from CVS:
* gst/gstpad.c: Remove handling of filtered caps. Fix/merge
functions that handle filtered links.
* gst/gstpad.h: Remove 'appfilter' field and prototypes of
removed functions.
* gst/gstutils.c: Fix/remove utility functions that handle
filtered caps.
* gst/gstutils.h:
* gst/gstvalue.c: Add serialization/deserialization of caps
* gst/parse/grammar.y: Ignore filtered caps when linking. This
requires fixing so that the filter caps notation creates
a capsfilter element and sets the filter_caps property. I
think everyone probably wants to keep the shorthand notation.
* docs/gst/tmpl/gstelement.sgml: updates for API changes.
* docs/gst/tmpl/gstpad.sgml:
* gst/elements/gstelements.c: Register capsfilter element.
* gst/Makefile.am: fix spacing
* docs/random/ds/0.9-suggested-changes: random
Original commit message from CVS:
* gst/elements/Makefile.am:
* gst/elements/gstcapsfilter.c: New element that acts like an
identity, but filters caps. Will eventually replace filtered
caps in pad linking.
* gst/gstutils.c: (gst_element_create_all_pads): New function
to create all the ALWAYS pads that are registered with an
element class. This functionality should eventually be
merged in with GstElement initialization.
* gst/gstutils.h:
* testsuite/trigger/README: part of trigger test code that should
have been checked in a long time ago.
Original commit message from CVS:
* gst/Makefile.am: Remove as-libtool stuff. It's likely not

Remove threadsafe properties. Fix elements because GObject
complains when installing a property before declaring a
set/get_property handler.
Rearrange gstelement.h file, use STATE macros for state locks.
Free mutexes in the finalize method instead of dispose.
Original commit message from CVS:
First THREADED backport attempt, focusing on adding locks and
making sure the API is threadsafe. Needs more work. More docs
follow this week.
Original commit message from CVS:
* gst/gstbin.c: (gst_bin_remove_func):
Explicitely make an element release locks in a group when being

If there's no scheduler, always return immediately (similar to
gst_element_interrupt).

for a while) without interrupting the actual data-stream.
Basically a no-op.

(gst_bin_unset_element_sched): Make sure that all elements and
links are registered and unregistered with the scheduler exactly
once. This elaborates on a fix by Benjamin Otte, but
guarantees that decoupled elements are also registered.

* gst/elements/gsttypefind.c: (stop_typefinding):

This is needed to allow downstream elements to seek. Otherwise
typefind might overwrite a previous seek by downstream elements.

Original commit message from CVS:
* gst/gstqueue.c: (gst_queue_init):
Reset default max. values in queues. Reason is simply to avoid
braindead use. If you want wider values, use the properties. The
default is supposed to always work. Wider values would make this
beast a memory hog by default (250 full-PAL RGB32 video frames?
That's 440 MB! No thank you).

* gst/gstbin.c: (gst_bin_change_state), (gst_bin_iterate): Fix a big
bug that was breaking pipelines like sinesrc ! { queue ! osssink } when
an error was thrown by osssink. Basically a state change failure for
an element in a different scheduling group was considered as successfull , which means that caps nego was going on and weird stuff happened. Like i wrote in the comment there, if someone want to revert that please
drop me a mail explaining why because i really see no point in keeping
that broken behaviour there.
* gst/gstqueue.c: (gst_queue_get): Add a safety check as the queue CAN

* gst/gstdata.c: (gst_data_ref): Adding a categorized debug on data_ref
because data_unref has one and i prefer the debug to be symetric.
* gst/gstqueue.c: (gst_queue_locked_flush): Fix a huge memleak. Buffers
were refed when added to the queue and unrefed only once when the queue
was flushed. Now the flush handler unref the buffers two times : first
unref for the ref added when pushing in the queue's tail and second
unref to destroy the flushed buffer.
Original commit message from CVS:
Trying to fix the mess that I made with the two previous commits.
First commit, doing something wrong (fixing comparisons of signed and unsigned).
Second commit, trying to revert the previous, but changing other things and

(gst_queue_chain), (gst_queue_handle_src_event):
implement timeout for sending events. Workaround for if the
pipeline on this queue is not passing any data.
Original commit message from CVS:
Fix a deadlock that happens if the next element sends an event and the previous element sends a buffer where the queue is full. See the comment in the code for the rest.
Original commit message from CVS:
This is either a rewrite or a large bugfix to the queue element, whatever
you prefer to call it.
* upstream event forwarding now works. This should fix Julien's issues.
* this queue allows setting a min. treshold size and a max. limit size
in bytes, buffers and time before the queue allows the next element
to pull data or the previous element to push data into it. This is
very interesting for network-related buffering. Also includes signals
et all for the end user application.
* Events are no longer part of the queue's "size", they're essentially
seen as "void data". they have no size or time associated with them
anyway, so this shouldn't really sound weird.
Original commit message from CVS:
implement URI schemes
Elements can now register as a source or sink for a protocol and applications can use gst_element_make_from_uri () to get an element that handles a given URI.
This patch provides:
- removal of old broken URI handling scheme.
- new URI handling using interfaces.
- updates for registry to save handled URIs.
- interface for URI handlers.
- implementation of that in filesrc and filesink for the file:// URI
- extension to pipeline parsing to allow specifying only a URI instead of element
Does not include:
- tests
- inclusion in docs build
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:
kill some memleaks, add ::signal-handoffs property to fakesrc/sink (default FALSE), cache return values of _gst_debug_nameof_funcptr
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:
I don't know how I ever got to introducing this madness, but I was wrong. *REALLY* wrong. It hasn't even worked, it still doesn't work and it will never work because the whole concept of doing a multifile output in filesink is completely braindead. Signal EOS, close file, set new filename and reset to PLAYING is so much easier. This patch removes all the multifile output cruft that I introduced and makes filesink simply work.
Original commit message from CVS:
Add patch for better buffering (especially useful for network streaming), see #108268 - kudos go to janzen@pixelmetrix.com
Original commit message from CVS:
- the result from the getcaps function should be sunken (gst_caps_sink)
instead of unreffed. Not sure that's the right thing to do...
Original commit message from CVS:
- First attempt at implementing #113180, this one also removes
automatic (byte) offset calculations in the subbuffer code and moves
that logic to bytestream and filesrc. It will also update the offset
and duration fields in some special cases.
Original commit message from CVS:
Ouch: gst_element_dispose does a state change to NULL. Change the state to NULL yourself if you dispose plugins that reference some of the freed memory on state changes.
This is probably broken in lots of cases.
Original commit message from CVS:
Fix various inconsistencies discovered while attempting to fix --disable-*.
Uraeus: this should fix the bison.simple problem that you've had.
Original commit message from CVS:
Convert %lld and %llu in printf formats to G_G[U]INT64_FORMAT. Fix
pointer<->int conversion. Fixes warnings on alpha.
Original commit message from CVS:
- Proxy the get_caps function slightly differently. This is potentially
dangerous as it works quite differently. My tests seem to work though and
it fixes the play-multi-file-segfault in the player.
Original commit message from CVS:
Replace __alignof__() GCC-ism with sizeof(). Should produce exactly
the same code on all architectures except perhaps m68k.
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:
More forte compiler fixes, added a .h file to store commonly used macros
that have to ifdefed out on non-gcc compilers
Original commit message from CVS:
- Added first attempt at general caching mechanism (GstTimeCache renamed
to GstCache)
- Some more clocking checks and updates (waiting on GST_CLOCK_TIME_NONE
returns immediatly instead of blocking forever)
- Moved clock get/set functions to element class instead of instance.
- Added cache methods on elements.
- Renamed GST_PROPS_BOOL_TYPE to GST_PROPS_BOOLEAN_TYPE to make it more
consistent with gst_props_get/set_boolean and GST_PROPS_BOOLEAN.
- Give short stats about plugins in gst-inspect.
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:
- Documentation updates, renamed some _ methods because gtkdoc didn't
want to generate docs for them.
- Add some more events for future use.
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
- update core plugins to the new event API
Original commit message from CVS:
Don't seek past the end of the file
Fix a bug where the mapend was incorrectly calculated when we read past
the end of the file.
Original commit message from CVS:
Whan the buffer is filled, the buffer is kept and added to the queue
when there is room again. Don't do this after a flush.
Original commit message from CVS:
put upstream events in an async queue and resend them at the start of the chain. not working as expected yet but a start
Original commit message from CVS:
add an optional timeout for when queue blocks. when timeout is reached a GST_EVENT_FILLER is sent downstream
This is needed for gst-player since videosink has to be in the same thread as the ui, and spider blocks when there is no video (thus freezing the ui).
Original commit message from CVS:
Created an overridable method for seeking on an element, along with a default
implementation.
make queue flush on discont (not entirely correct)
removed the new_media from the discont event.
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:
* add gerror to gstplugin.c -- not fully propagated to periphery apis
* fix recursive dir creation in the xml registry
* comment identity props
* fix dependency resolution in lib loading
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:
* a hack to work around intltool's brokenness
* a current check for mpeg2dec
* details->klass reorganizations
* an element browser that uses details->klass
* separated cdxa parse out from the avi directory
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:
patch from jim thornton <jthornton@parc.com>:
Buffer flag symbols are enum values, so |'ing together doesn't do the right
thing, must use GST_BUFFER_FLAG_SET macro
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
* some jack updates
* remove SELF_ITERATING flag in favor of SEF_SCHEDULABLE (not a clear name,
but it's what we have for the moment)
* improve parsing of request pad names, no more sscanf
* fixes to the fastscheduler Makefile.am
Original commit message from CVS:
- Remove the propsprivate header file
- Added new API for properties.
- Moved the clock distribution to the scheduler.
- Removed the lock from GstCaps
- Added boxed types for Caps/Props
- Simplified the clock, new systemclock implementation
- Removed deprecated element_info/send_event functions
- First step at exposing more info in the pad_connect functions
- Queue cleanup
- Make the scheduler aware of other schedulers inside it
- Added the _SELF_SCHEDULABLE flag to gstthread
- Removed _get_widget from _utils, changed to new props API
- Make fakesink sync on timestamps when requested
- Removed the offset notify from filesrc
- Added a fast scheduler
- some scheduler cleanups.
Original commit message from CVS:
* removal of //-style comments
* don't link plugins to core libs -- the versioning is done internally to the plugins with the plugin_info struct,
and symbol resolution is lazy, so we can always know if a plugin can be loaded by the plugin_info data. in theory.
Original commit message from CVS:
s/@GST_PLUGIN_LDFLAGS@/$(GST_PLUGIN_LDFLAGS)/
@-substitued variables variables are defined as make variables automagically,
and this gives the user the freedom to say make GST_PLUGIN_LDFLAGS=-myflag
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
* fixen on launch-gui
* 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:
* changes to spider:
* add padtemplates so the connect functions can connect two request-pad
elements
* add a hack in gstelement.c. please look at this, Company, and see how
we can get around this
* add backwards caps-propagation support in identity, int2float, float2int,
adder, speed, volume
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
