|
2005-10-15 15:30:24 +00:00
|
|
|
* If the link is straightforward, use the gst_element_link()
|
|
|
|
* convenience function to link two elements, or gst_element_link_many()
|
2005-09-23 14:31:21 +00:00

* for more elements in a row.
|
|

|
|
|
* a specified set of #GstCaps.
|
2005-10-15 15:30:24 +00:00
|
|
|
* For finer control, use gst_element_link_pads() and

* gst_element_link_pads_filtered() to specify the pads to link on
|
2005-09-23 14:31:21 +00:00

* Each element has a state (see #GstState). You can get and set the state
|
2005-10-15 15:30:24 +00:00
|
|
|
* of an element with gst_element_get_state() and gst_element_set_state().
|
2009-12-14 13:11:42 +00:00
|
|
|
* Setting a state triggers a #GstStateChange. To get a string representation
|
|
|
|
* of a #GstState, use gst_element_state_get_name().

|
2005-09-23 14:31:21 +00:00
|
|
|
* You can get and set a #GstClock on an element using gst_element_get_clock()
|
2005-10-15 15:30:24 +00:00
|
|
|
* and gst_element_set_clock().
|
|
|
|
* Some elements can provide a clock for the pipeline if
|
2006-02-06 15:25:26 +00:00
|
|
|
* gst_element_provides_clock() returns %TRUE. With the
|
|
|
|
* gst_element_provide_clock() method one can retrieve the clock provided by
|
|
|
|
* such an element.
|
2005-10-15 15:30:24 +00:00
|
|
|
* Not all elements require a clock to operate correctly. If
|
2006-01-27 22:34:51 +00:00
|
|
|
* gst_element_requires_clock() returns %TRUE, a clock should be set on the
|
2005-10-15 16:01:57 +00:00
|
|
|
* element with gst_element_set_clock().

|
|
|
*
|
2005-10-15 16:01:57 +00:00
|
|
|
* Note that clock slection and distribution is normally handled by the
|
|
|
|
* toplevel #GstPipeline so the clock functions are only to be used in very
|
|
|
|
* specific situations.

docs/gst/gstreamer-sections.txt: Add new element field and method.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
Add new element field and method.
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_init),
(bin_remove_messages), (gst_bin_add_func), (gst_bin_remove_func),
(gst_bin_recalc_state), (gst_bin_get_state_func),

(gst_bin_continue_func), (bin_bus_handler),
(bin_push_state_continue), (bin_handle_async_start),
(bin_handle_async_done), (gst_bin_handle_message_func):
Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.
* gst/gstelement.c: (gst_element_init), (gst_element_send_event),
(gst_element_get_state_func), (gst_element_continue_state),
(gst_element_lost_state), (gst_element_set_state_func),
(gst_element_change_state):
* gst/gstelement.h:
Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)
Export gst_element_change_state() method so that subclasses can use it.
API: gst_element_change_state()
API: GST_STATE_TARGET
* gst/gstpipeline.c: (gst_pipeline_class_init),
(reset_stream_time), (gst_pipeline_change_state),
(gst_pipeline_handle_message), (gst_pipeline_set_new_stream_time):
Using the new ASYNC_START message we can reset the base_time when
needed. This can then be used to implement base_time redistribution in
flushing seeks so that we can remove the explicit seek handling.
Perform latency query and configuration when going to PLAYING.
* libs/gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_query), (gst_base_sink_change_state):
Post new ASYNC_START/ASYNC_DONE messages.

Fix test because the bin will not set the async element to PLAYING right
away.

Make the message check a little stronger.
Handle ASYNC messages.

Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.

* gst/gstelement.h:
Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)
Export gst_element_change_state() method so that subclasses can use it.
API: gst_element_change_state()
API: GST_STATE_TARGET
* gst/gstpipeline.c: (gst_pipeline_class_init),
(reset_stream_time), (gst_pipeline_change_state),
(gst_pipeline_handle_message), (gst_pipeline_set_new_stream_time):
Using the new ASYNC_START message we can reset the base_time when
needed. This can then be used to implement base_time redistribution in
flushing seeks so that we can remove the explicit seek handling.
Perform latency query and configuration when going to PLAYING.
* libs/gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_query), (gst_base_sink_change_state):
Post new ASYNC_START/ASYNC_DONE messages.

Fix test because the bin will not set the async element to PLAYING right
away.
* tests/check/gst/gstbin.c: (pop_async_done), (GST_START_TEST):
Make the message check a little stronger.
Handle ASYNC messages.

gst/gstclock.*: deprecate old interface and disable functions that aren't in use anymore.
Original commit message from CVS:
2004-01-13 Benjamin Otte <in7y118@public.uni-hamburg.de>
* gst/gstclock.c: (gst_clock_class_init), (gst_clock_init),
(gst_clock_set_speed), (gst_clock_set_active),
(gst_clock_is_active), (gst_clock_reset),
(gst_clock_handle_discont):
* gst/gstclock.h:
deprecate old interface and disable functions that aren't in use
anymore.
* gst/gstelement.h:
* gst/gstelement.c: (gst_element_get_time), (gst_element_wait),
(gst_element_set_time), (gst_element_adjust_time):
add concept of "element time" and functions to get/set this time.
* gst/gstelement.c: (gst_element_change_state):
update element time correctly.
* gst/gstelement.c: (gst_element_get_compatible_pad_filtered):
This is a debug message, not a g_critical.
* gst/gstpad.c: (gst_pad_event_default):
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):
remove code that just implements the default behaviour.
* gst/elements/gstfakesink.c: (gst_fakesink_chain):
update to use new clocking functions
* testsuite/clock/clock1.c: (gst_clock_debug), (main):
* testsuite/clock/clock2.c: (gst_clock_debug), (main):
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.
* testsuite/debug/commandline.c:
update for new GST_DEBUG syntax.
* testsuite/threads/Makefile.am:
disable a test that only works sometimes.

what kind of data they're dealing with.

type implementation, now does the same instead of allocating empty

These two routines are the only ones that set
GST_GPAD_REALPAD(gpad), the ghost pad list, and the ghost pad's
pad template. They should be made static, depending on ABI needs.
(gst_real_pad_dispose): Handle the case of ghost pads without a
parent. Assert after dealing with ghost pads that the ghost pad
list is empty.

set after creation.
(gst_ghost_pad_dispose): Set ::real-pad to NULL.
(gst_ghost_pad_set_property, gst_ghost_pad_get_property): New
functions. set_property will call add_ghost_pad/remove_ghost_pad
as appropriate.

gst/gstutils.c: RPAD fixes all around.
Original commit message from CVS:
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.

* gst/gstpad.c (gst_real_pad_class_init): Use a BOXED:BOXED

* gst/gstpad.c (_gst_real_pad_fixate_accumulator):
s/pointer/boxed/.
* gst/gstmarshal.list (VOID:BOXED, BOXED:BOXED): New marshallers.
* gst/gstpad.c (gst_real_pad_class_init): Use a BOXED:BOXED
marshaller for ::fixate, and VOID:BOXED for ::caps-nego-failed,
with the type=GST_TYPE_CAPS. This allows language bindings to know
what kind of data they're dealing with.
* gst/gstcaps.c (_gst_caps_value_init): GBoxed values initialize
to NULL when g_value_init is called. GstCaps, which rolls its own
type implementation, now does the same instead of allocating empty
caps.
(_gst_caps_initialize, _gst_caps_collect_value,
_gst_caps_lcopy_value): Provide collect_value and lcopy_value type
table methods. This allows G_VALUE_COLLECT to work.

pad template. They should be made static, depending on ABI needs.
(gst_real_pad_dispose): Handle the case of ghost pads without a

list is empty.
(gst_ghost_pad_class_init): New property added, ::real-pad. Can be
set after creation.
(gst_ghost_pad_dispose): Set ::real-pad to NULL.
(gst_ghost_pad_set_property, gst_ghost_pad_get_property): New
functions. set_property will call add_ghost_pad/remove_ghost_pad

returns a sorted copy of the trace list.
(gst_alloc_trace_print_live): New API, only prints traces with
live objects. Sort the list.
(gst_alloc_trace_print_all): Sort the list.

* gst/elements/gsttee.c:
* gst/base/gstbasesrc.c:
* gst/base/gstbasesink.c:
* gst/base/gstbasetransform.c:

* gst/gstpipeline.c (gst_pipeline_init): Unref after parenting
sched.
(gst_pipeline_dispose): Drop ref on sched.
* gst/gstpad.c (gst_pad_init): Set the default activate func.
(gst_pad_activate_default): Push mode by default.
(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.
(gst_pad_set_activate_function)
(gst_pad_set_activatepull_function)
(gst_pad_set_activatepush_function): Setters for new API.
* gst/gstminiobject.c (gst_mini_object_new, gst_mini_object_free):

test, runs fakesrc ! fakesink, stopping on ::handoff via a message
to the bus.
(assert_live_count): New util function, uses alloc traces to check
cleanup.
* check/gst/gstghostpad.c (test_ghost_pads): More refcount checks.
To be modified when unlink drops the internal pad.

* gst/gstpad.c (_gst_real_pad_fixate_accumulator):
s/pointer/boxed/.
* gst/gstmarshal.list (VOID:BOXED, BOXED:BOXED): New marshallers.
* gst/gstpad.c (gst_real_pad_class_init): Use a BOXED:BOXED
marshaller for ::fixate, and VOID:BOXED for ::caps-nego-failed,
with the type=GST_TYPE_CAPS. This allows language bindings to know
what kind of data they're dealing with.
* gst/gstcaps.c (_gst_caps_value_init): GBoxed values initialize
to NULL when g_value_init is called. GstCaps, which rolls its own
type implementation, now does the same instead of allocating empty
caps.
(_gst_caps_initialize, _gst_caps_collect_value,
_gst_caps_lcopy_value): Provide collect_value and lcopy_value type
table methods. This allows G_VALUE_COLLECT to work.

* testsuite/ghostpads/Makefile.am:
* testsuite/ghostpads/ghostpads.c: A new test for ghost pads.
* gst/gstpad.c (gst_pad_add_ghost_pad, gst_pad_remove_ghost_pad):
These two routines are the only ones that set
GST_GPAD_REALPAD(gpad), the ghost pad list, and the ghost pad's
pad template. They should be made static, depending on ABI needs.
(gst_real_pad_dispose): Handle the case of ghost pads without a
parent. Assert after dealing with ghost pads that the ghost pad
list is empty.
(gst_ghost_pad_class_init): New property added, ::real-pad. Can be
set after creation.
(gst_ghost_pad_dispose): Set ::real-pad to NULL.
(gst_ghost_pad_set_property, gst_ghost_pad_get_property): New
functions. set_property will call add_ghost_pad/remove_ghost_pad
as appropriate.
(gst_ghost_pad_new): All the work is offloaded to g_object_new.
* gst/gstelement.c (gst_element_add_pad): Handle ghost pads as well.
(gst_element_add_ghost_pad): Remove code duplicated from _add_pad.
(gst_element_remove_pad): Handle ghost pads as well.
(gst_element_remove_ghost_pad): Deprecated (could be removed,
depending on API-stability needs).

docs/gst/gstreamer-sections.txt: Add new element field and method.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
Add new element field and method.
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_init),
(bin_remove_messages), (gst_bin_add_func), (gst_bin_remove_func),
(gst_bin_recalc_state), (gst_bin_get_state_func),

(gst_bin_continue_func), (bin_bus_handler),
(bin_push_state_continue), (bin_handle_async_start),
(bin_handle_async_done), (gst_bin_handle_message_func):
Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.
* gst/gstelement.c: (gst_element_init), (gst_element_send_event),
(gst_element_get_state_func), (gst_element_continue_state),
(gst_element_lost_state), (gst_element_set_state_func),
(gst_element_change_state):
* gst/gstelement.h:
Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set

docs/gst/gstreamer-sections.txt: Add new element field and method.

Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.

Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.

Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)

(gst_element_release_request_pad), (gst_element_set_clock),
(gst_element_get_index), (gst_element_add_pad),
(gst_element_remove_pad), (gst_element_get_random_pad),
(gst_element_send_event), (gst_element_get_query_types),

(gst_element_message_full), (gst_element_continue_state),
(gst_element_lost_state), (gst_element_save_thyself),
(gst_element_restore_thyself):
Documentation updates.
Rename last bit of the new-pad -> pad-added signal rename.
Fix the case where an element query would only work if the source
pad was linked.
Avoid some useless type checking in message handling.
* gst/gstevent.c:
* gst/gstevent.h:
* gst/gstutils.c:
Documentation updates.

* gst/gstbin.h:
Immediatly commit the toplevel bin state when receiving an async-done
message. This enables us to avoid spawning a thread to commit the state
in some common cases and it also avoids some races.
Avoid spawning a state thread when adding/removing async elements to a
toplevel bin. Instead we immediatly update the bin state.
Get rid of iterating all the children when getting the state in the bin
because it is now always up-to-date.
Fix bug where locked elements would always return _SUCCESS even it they
returned NO_PREROLL before being locked.
Fix the order of the state_change, async-start/done messages that was
sometimes incorrect.
Mark the state_dirty field as deprecated, we don't need it anymore as we
are always up-to-date.
* gst/gstelement.c: (gst_element_get_state_func),
(gst_element_continue_state):
Small debug inprovements.
Return the previous element state return when nothing is pending instead
of blindly returning SUCCESS.
* tests/check/generic/sinks.c: (GST_START_TEST), (pad_blocked_cb),
(gst_sinks_suite):
Add a whole bunch of new testcases.

Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.

Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)
Export gst_element_change_state() method so that subclasses can use it.

Using the new ASYNC_START message we can reset the base_time when

flushing seeks so that we can remove the explicit seek handling.
Perform latency query and configuration when going to PLAYING.

docs/gst/gstreamer-sections.txt: Add new element field and method.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
Add new element field and method.
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_init),
(bin_remove_messages), (gst_bin_add_func), (gst_bin_remove_func),
(gst_bin_recalc_state), (gst_bin_get_state_func),
(gst_bin_element_set_state), (gst_bin_change_state_func),
(gst_bin_continue_func), (bin_bus_handler),
(bin_push_state_continue), (bin_handle_async_start),
(bin_handle_async_done), (gst_bin_handle_message_func):
Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.
* gst/gstelement.c: (gst_element_init), (gst_element_send_event),
(gst_element_get_state_func), (gst_element_continue_state),
(gst_element_lost_state), (gst_element_set_state_func),
(gst_element_change_state):
* gst/gstelement.h:
Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)
Export gst_element_change_state() method so that subclasses can use it.
API: gst_element_change_state()
API: GST_STATE_TARGET
* gst/gstpipeline.c: (gst_pipeline_class_init),
(reset_stream_time), (gst_pipeline_change_state),
(gst_pipeline_handle_message), (gst_pipeline_set_new_stream_time):
Using the new ASYNC_START message we can reset the base_time when
needed. This can then be used to implement base_time redistribution in
flushing seeks so that we can remove the explicit seek handling.
Perform latency query and configuration when going to PLAYING.
* libs/gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_query), (gst_base_sink_change_state):
Post new ASYNC_START/ASYNC_DONE messages.
* tests/check/generic/sinks.c: (GST_START_TEST):
Fix test because the bin will not set the async element to PLAYING right
away.
* tests/check/gst/gstbin.c: (pop_async_done), (GST_START_TEST):
Make the message check a little stronger.
Handle ASYNC messages.
* tests/check/pipelines/cleanup.c: (GST_START_TEST):
* tests/check/pipelines/simple-launch-lines.c: (GST_START_TEST):
Expect ASYNC_DONE messages.

Original commit message from CVS:

Small state change torture test.

* gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_handle_object), (gst_base_sink_event), (do_playing),
(gst_base_sink_change_state):
Never take state lock from streaming thread, clean up ugly
hacks. Unfortunatly core does not yet support nice ways to
async commit state.
* gst/gstbin.c: (gst_bin_remove_func), (gst_bin_recalc_state),
(bin_bus_handler):
Start state recalc if a STATE_DIRTY message is posted, but only
on the toplevel bin.

(gst_element_set_state_func), (gst_element_change_state):
* gst/gstelement.h:
State variables are now protected with the LOCK, the state
lock is only used to serialize _set_state().

docs/gst/gstreamer-sections.txt: Add new element field and method.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
Add new element field and method.
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_init),
(bin_remove_messages), (gst_bin_add_func), (gst_bin_remove_func),
(gst_bin_recalc_state), (gst_bin_get_state_func),

(gst_bin_continue_func), (bin_bus_handler),
(bin_push_state_continue), (bin_handle_async_start),
(bin_handle_async_done), (gst_bin_handle_message_func):
Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.
* gst/gstelement.c: (gst_element_init), (gst_element_send_event),
(gst_element_get_state_func), (gst_element_continue_state),
(gst_element_lost_state), (gst_element_set_state_func),
(gst_element_change_state):
* gst/gstelement.h:
Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)
Export gst_element_change_state() method so that subclasses can use it.
API: gst_element_change_state()
API: GST_STATE_TARGET
* gst/gstpipeline.c: (gst_pipeline_class_init),
(reset_stream_time), (gst_pipeline_change_state),
(gst_pipeline_handle_message), (gst_pipeline_set_new_stream_time):
Using the new ASYNC_START message we can reset the base_time when
needed. This can then be used to implement base_time redistribution in
flushing seeks so that we can remove the explicit seek handling.
Perform latency query and configuration when going to PLAYING.
* libs/gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_query), (gst_base_sink_change_state):
Post new ASYNC_START/ASYNC_DONE messages.
* tests/check/generic/sinks.c: (GST_START_TEST):
Fix test because the bin will not set the async element to PLAYING right
away.
* tests/check/gst/gstbin.c: (pop_async_done), (GST_START_TEST):
Make the message check a little stronger.
Handle ASYNC messages.
* tests/check/pipelines/cleanup.c: (GST_START_TEST):
* tests/check/pipelines/simple-launch-lines.c: (GST_START_TEST):
Expect ASYNC_DONE messages.

docs/gst/gstreamer-sections.txt: Add new element field and method.
Original commit message from CVS:
* docs/gst/gstreamer-sections.txt:
Add new element field and method.
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_init),
(bin_remove_messages), (gst_bin_add_func), (gst_bin_remove_func),
(gst_bin_recalc_state), (gst_bin_get_state_func),

(gst_bin_continue_func), (bin_bus_handler),
(bin_push_state_continue), (bin_handle_async_start),
(bin_handle_async_done), (gst_bin_handle_message_func):
Make async state changes a bit smarter by using new ASYNC_START and
ASYNC_DONE messages. This reduces the number of times we run the state
recalculation thread.
Don't change state of element with a pending ASYNC_START message.
Deprecate STATE_DIRTY messages.
* gst/gstelement.c: (gst_element_init), (gst_element_send_event),
(gst_element_get_state_func), (gst_element_continue_state),
(gst_element_lost_state), (gst_element_set_state_func),
(gst_element_change_state):
* gst/gstelement.h:
Keep the state that was last set by the app in a new element field.
Don't allow state changes when handling an element event.
Post ASYNC_START and ASYNC_DONE messages.
Change lost_state so that we go to PAUSED and wait for the parent to set
us to PLAYING again (so latency calculation can be performed)
Export gst_element_change_state() method so that subclasses can use it.
API: gst_element_change_state()
API: GST_STATE_TARGET
* gst/gstpipeline.c: (gst_pipeline_class_init),
(reset_stream_time), (gst_pipeline_change_state),
(gst_pipeline_handle_message), (gst_pipeline_set_new_stream_time):
Using the new ASYNC_START message we can reset the base_time when
needed. This can then be used to implement base_time redistribution in
flushing seeks so that we can remove the explicit seek handling.
Perform latency query and configuration when going to PLAYING.
* libs/gst/base/gstbasesink.c: (gst_base_sink_commit_state),
(gst_base_sink_query), (gst_base_sink_change_state):
Post new ASYNC_START/ASYNC_DONE messages.
* tests/check/generic/sinks.c: (GST_START_TEST):
Fix test because the bin will not set the async element to PLAYING right
away.
* tests/check/gst/gstbin.c: (pop_async_done), (GST_START_TEST):
Make the message check a little stronger.
Handle ASYNC messages.
* tests/check/pipelines/cleanup.c: (GST_START_TEST):
* tests/check/pipelines/simple-launch-lines.c: (GST_START_TEST):
Expect ASYNC_DONE messages.

gst/base/gsttypefindhelper.c (gst_type_find_helper): Unref any remaining buffer.
Original commit message from CVS:

* gst/base/gsttypefindhelper.c (gst_type_find_helper): Unref any
remaining buffer.
* gst/gsttrace.c (gst_alloc_trace_list_sorted): New helper,
returns a sorted copy of the trace list.
(gst_alloc_trace_print_live): New API, only prints traces with
live objects. Sort the list.
(gst_alloc_trace_print_all): Sort the list.
(gst_alloc_trace_print): Align columns.
* gst/elements/gstttypefindelement.c:
* gst/elements/gsttee.c:
* gst/base/gstbasesrc.c:
* gst/base/gstbasesink.c:
* gst/base/gstbasetransform.c:
* gst/gstqueue.c: Adapt for pad activation changes.
* gst/gstpipeline.c (gst_pipeline_init): Unref after parenting
sched.
(gst_pipeline_dispose): Drop ref on sched.
* gst/gstpad.c (gst_pad_init): Set the default activate func.
(gst_pad_activate_default): Push mode by default.
(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.
(gst_pad_set_activate_function)
(gst_pad_set_activatepull_function)
(gst_pad_set_activatepush_function): Setters for new API.
* gst/gstminiobject.c (gst_mini_object_new, gst_mini_object_free):
Trace all miniobjects.
(gst_mini_object_make_writable): Unref the arg if we copy, like
gst_caps_make_writable.
* gst/gstmessage.c (_gst_message_initialize): No trace init.
* gst/gstghostpad.c (gst_proxy_pad_do_activate)
(gst_proxy_pad_do_activatepull, gst_proxy_pad_do_activatepush):
Adapt for new pad API.
* gst/gstevent.c (_gst_event_initialize): Don't initialize trace.
* gst/gstelement.h:
* gst/gstelement.c (gst_element_iterate_src_pads)
(gst_element_iterate_sink_pads): New API functions.
* gst/gstelement.c (iterator_fold_with_resync): New utility,
should fold into gstiterator.c in some form.
(gst_element_pads_activate): Simplified via use of fold and
delegation of decisions to gstpad->activate.
* gst/gstbus.c (gst_bus_source_finalize): Set the bus to NULL,
help in debugging.
* gst/gstbuffer.c (_gst_buffer_initialize): Ref the buffer type
class once in init, like gstmessage. Didn't run into this issue
but it seems correct. Don't initialize a trace, gstminiobject does
that.
* check/pipelines/simple_launch_lines.c (test_stop_from_app): New
test, runs fakesrc ! fakesink, stopping on ::handoff via a message
to the bus.
(assert_live_count): New util function, uses alloc traces to check
cleanup.
* check/gst/gstghostpad.c (test_ghost_pads): More refcount checks.
To be modified when unlink drops the internal pad.

gst/gstutils.c: RPAD fixes all around.
Original commit message from CVS:
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.

gst/gstutils.c: RPAD fixes all around.
Original commit message from CVS:
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.

gst/base/gsttypefindhelper.c (gst_type_find_helper): Unref any remaining buffer.
Original commit message from CVS:
2005-06-27 Andy Wingo <wingo@pobox.com>
* gst/base/gsttypefindhelper.c (gst_type_find_helper): Unref any
remaining buffer.
* gst/gsttrace.c (gst_alloc_trace_list_sorted): New helper,
returns a sorted copy of the trace list.
(gst_alloc_trace_print_live): New API, only prints traces with
live objects. Sort the list.
(gst_alloc_trace_print_all): Sort the list.
(gst_alloc_trace_print): Align columns.
* gst/elements/gstttypefindelement.c:
* gst/elements/gsttee.c:
* gst/base/gstbasesrc.c:
* gst/base/gstbasesink.c:
* gst/base/gstbasetransform.c:
* gst/gstqueue.c: Adapt for pad activation changes.
* gst/gstpipeline.c (gst_pipeline_init): Unref after parenting
sched.
(gst_pipeline_dispose): Drop ref on sched.
* gst/gstpad.c (gst_pad_init): Set the default activate func.
(gst_pad_activate_default): Push mode by default.
(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.
(gst_pad_set_activate_function)
(gst_pad_set_activatepull_function)
(gst_pad_set_activatepush_function): Setters for new API.
* gst/gstminiobject.c (gst_mini_object_new, gst_mini_object_free):
Trace all miniobjects.
(gst_mini_object_make_writable): Unref the arg if we copy, like
gst_caps_make_writable.
* gst/gstmessage.c (_gst_message_initialize): No trace init.
* gst/gstghostpad.c (gst_proxy_pad_do_activate)
(gst_proxy_pad_do_activatepull, gst_proxy_pad_do_activatepush):
Adapt for new pad API.
* gst/gstevent.c (_gst_event_initialize): Don't initialize trace.
* gst/gstelement.h:
* gst/gstelement.c (gst_element_iterate_src_pads)
(gst_element_iterate_sink_pads): New API functions.
* gst/gstelement.c (iterator_fold_with_resync): New utility,
should fold into gstiterator.c in some form.
(gst_element_pads_activate): Simplified via use of fold and
delegation of decisions to gstpad->activate.
* gst/gstbus.c (gst_bus_source_finalize): Set the bus to NULL,
help in debugging.
* gst/gstbuffer.c (_gst_buffer_initialize): Ref the buffer type
class once in init, like gstmessage. Didn't run into this issue
but it seems correct. Don't initialize a trace, gstminiobject does
that.
* check/pipelines/simple_launch_lines.c (test_stop_from_app): New
test, runs fakesrc ! fakesink, stopping on ::handoff via a message
to the bus.
(assert_live_count): New util function, uses alloc traces to check
cleanup.
* check/gst/gstghostpad.c (test_ghost_pads): More refcount checks.
To be modified when unlink drops the internal pad.

gst/gstclock.*: deprecate old interface and disable functions that aren't in use anymore.
Original commit message from CVS:
2004-01-13 Benjamin Otte <in7y118@public.uni-hamburg.de>
* gst/gstclock.c: (gst_clock_class_init), (gst_clock_init),
(gst_clock_set_speed), (gst_clock_set_active),
(gst_clock_is_active), (gst_clock_reset),
(gst_clock_handle_discont):
* gst/gstclock.h:
deprecate old interface and disable functions that aren't in use
anymore.
* gst/gstelement.h:
* gst/gstelement.c: (gst_element_get_time), (gst_element_wait),
(gst_element_set_time), (gst_element_adjust_time):
add concept of "element time" and functions to get/set this time.
* gst/gstelement.c: (gst_element_change_state):
update element time correctly.
* gst/gstelement.c: (gst_element_get_compatible_pad_filtered):
This is a debug message, not a g_critical.
* gst/gstpad.c: (gst_pad_event_default):
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):
remove code that just implements the default behaviour.
* gst/elements/gstfakesink.c: (gst_fakesink_chain):
update to use new clocking functions
* testsuite/clock/clock1.c: (gst_clock_debug), (main):
* testsuite/clock/clock2.c: (gst_clock_debug), (main):
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.
* testsuite/debug/commandline.c:
update for new GST_DEBUG syntax.
* testsuite/threads/Makefile.am:
disable a test that only works sometimes.

check/gst/gstbin.c: Add bus to bin.
Original commit message from CVS:
* check/gst/gstbin.c: (GST_START_TEST):
Add bus to bin.
* gst/gstbin.c: (gst_bin_class_init), (gst_bin_init),
(add_to_queue), (clear_queue), (reset_degree), (update_degree),
(find_element), (gst_bin_sort_iterator_next),
(gst_bin_sort_iterator_resync), (gst_bin_sort_iterator_free),
(gst_bin_iterate_sorted), (gst_bin_element_set_state),
(gst_bin_change_state), (gst_bin_dispose):
A bin does not have a bus, it gets the bus from the parent.
* gst/gstelement.c: (gst_element_requires_clock),
(gst_element_provides_clock), (gst_element_is_indexable),
(gst_element_is_locked_state), (gst_element_change_state),
(gst_element_set_bus_func):
Small cleanups.
* gst/gstpipeline.c: (gst_pipeline_class_init),
(gst_pipeline_init), (gst_pipeline_provide_clock_func):
The pipeline provides a bus.

gst/gstbin.*: Immediatly commit the toplevel bin state when receiving an async-done message. This enables us to avoid...
Original commit message from CVS:
* gst/gstbin.c: (gst_bin_init), (gst_bin_add_func),
(gst_bin_remove_func), (gst_bin_get_state_func),
(gst_bin_element_set_state), (gst_bin_continue_func),
(bin_push_state_continue), (bin_handle_async_start),
(bin_handle_async_done), (gst_bin_handle_message_func):
* gst/gstbin.h:
Immediatly commit the toplevel bin state when receiving an async-done
message. This enables us to avoid spawning a thread to commit the state
in some common cases and it also avoids some races.
Avoid spawning a state thread when adding/removing async elements to a
toplevel bin. Instead we immediatly update the bin state.
Get rid of iterating all the children when getting the state in the bin
because it is now always up-to-date.
Fix bug where locked elements would always return _SUCCESS even it they
returned NO_PREROLL before being locked.
Fix the order of the state_change, async-start/done messages that was
sometimes incorrect.
Mark the state_dirty field as deprecated, we don't need it anymore as we
are always up-to-date.
* gst/gstelement.c: (gst_element_get_state_func),
(gst_element_continue_state):
Small debug inprovements.
Return the previous element state return when nothing is pending instead
of blindly returning SUCCESS.
* tests/check/generic/sinks.c: (GST_START_TEST), (pad_blocked_cb),
(gst_sinks_suite):
Add a whole bunch of new testcases.
