Default to returning TRUE for the case when tranform_caps returns
a fixed caps, like for identity or volume.

* check/gst/gstbus.c (pound_bus_with_messages):
* check/gst/gstmessage.c (START_TEST):
* check/pipelines/simple_launch_lines.c (got_handoff): Application
message API change.
* gst/base/gstbasetransform.c (gst_base_transform_setcaps): More
logic weaks here: always run transform_caps, trying passthrough
operation only if the original caps intersects with the transform.
* gst/gstpad.c (gst_pad_link_check_compatible_unlocked): Debug
source and sink caps.
* gst/base/gstbasetransform.c (gst_base_transform_getcaps):
Intersect the peer caps with the pad template before going into
transform_caps.
(gst_base_transform_transform_caps): More debugging.

src argument.
Original commit message from CVS:
2005-07-01 Andy Wingo <wingo@pobox.com>
* tests/network-clock.scm: Commentary update.
* gst/elements/gstidentity.c (PROP_DUPLICATE): Gone daddy gone.
Didn't really make sense, not implementable with basetransform,
etc.
(gst_identity_transform): Unref inbuf via make_writable. Feeble
attempt at implementing the sync property, needs an unlock method.
* gst/base/gstbasetransform.c (gst_base_transform_transform_caps):
New func, by default returns the same caps (the identity
transformation).
(gst_base_transform_getcaps): Uses transform_caps to return
something sensible.
(gst_base_transform_setcaps): Complicated logic to get caps on
both pads, even if they are different, and to call set_caps once
for every time both pads get their caps set.
(gst_base_transform_handle_buffer): Give the ref to the transform
function. Allows in-place modification of the buffer.
* gst/base/gstbasetransform.h (transform_caps): New class method.
Given caps on one side, what can I do on the other.
(set_caps): Take two caps, one for each side of the element.
* gst/gstpad.h:
* gst/gstpad.c (gst_pad_fixate_caps): Change prototype to modify
caps in place. This is safe because we can check the mutability of
the caps, and a good idea because fixate functions are just called
as a matter of last resort. (Not actually implemented.)
(gst_pad_set_caps): If the caps we're setting is actually the same
as the existing pad caps, just update the pointer without calling
setcaps. Assert that caps is either NULL or fixed, as per the
docs.
* gst/gstghostpad.c: Update for fixate changes.
Original commit message from CVS:
* gst/base/gstbasesink.c: (gst_base_sink_preroll_queue_empty),
(gst_base_sink_preroll_queue_flush), (gst_base_sink_handle_object),
(gst_base_sink_change_state):
* gst/base/gstbasesink.h:
Some tweaks, only EOS and a buffer complete a preroll.
Original commit message from CVS:
* gst/base/gstbasesink.c: (gst_base_sink_handle_object),
(gst_base_sink_change_state):
Small debug line.
* gst/gstclock.h:
map SIGNAL and BROADCAST to the right function.
* gst/gstobject.h:
Remove redundant braces.
* gst/gstpad.c: (gst_pad_set_caps):
Don't call setcaps function when reseting caps to NULL.
* gst/gstsystemclock.c: (gst_system_clock_dispose),
(gst_system_clock_async_thread), (gst_system_clock_id_wait_async),
(gst_system_clock_id_unschedule):
Use BROADCAST as this is what we do.
Original commit message from CVS:
* gst/base/gstbasesink.c: (gst_base_sink_handle_object):
We are actually prerolling before commiting the state
change.
Original commit message from CVS:
* gst/base/gstbasesink.c: (gst_basesink_preroll_queue_flush),
(gst_basesink_event), (gst_basesink_deactivate):
Flushing the preroll queue always needs to unlock the waiters.
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/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.
Original commit message from CVS:
* gst/base/gstbasesink.c: (gst_basesink_preroll_queue_empty),
(gst_basesink_handle_object), (gst_basesink_event),
(gst_basesink_do_sync), (gst_basesink_handle_event),
(gst_basesink_change_state):
* gst/gsttask.h:
Right, two problems here: ghostpads don't take locks and
glib _rec_mutex_lock_full() with depth==0 still locks.
Catch illegal locking and g_warn them.

Reworked the base sink, handle event and buffer serialisation
correctly and removed possible deadlock.
Handle EOS correctly.

* gst/base/gstbasesrc.c (gst_basesrc_get_range): Check if the
offset is greater than the file's size.
Original commit message from CVS:
Added support for live sources and other elements that
cannot do preroll.
Updated design docs, added live-source design doc.
Implemented live source functionality in basesrc
Fix error condition in _bin_get_state()
Implement live source handling in -launch.
Added check for live sources.
Fixed case in GstBin where elements were changed state
multiple times.
Original commit message from CVS:
2005-06-17 Andy Wingo <wingo@pobox.com>
* gst/base/gstbasesink.c (gst_basesink_chain): Remove bogus
assert; it's always possible that the pad gets deactivated in
between the checks in gstpad.c and the implementation. Rely on
finish_preroll() to return a FLUSHING or similar instead of on the
assert.
Original commit message from CVS:
2005-06-17 Andy Wingo <wingo@pobox.com>
* gst/base/gstbasesink.c (gst_basesink_event): Only wait for the
clock and post an EOS message if we come out of finish_preroll in
the playing state.
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.
Original commit message from CVS:
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/base/gstbasesrc.c: (gst_basesrc_activate):
Don't go in pull mode for non-seekable sources.
* gst/elements/gsttypefindelement.c: (gst_type_find_element_init),

(gst_type_find_element_handle_event), (find_peek),
(gst_type_find_element_chain), (do_pull_typefind),
(gst_type_find_element_change_state):
Allow typefinding (w/o seeking) in push-mode, simplified version
of what was in 0.8.
* gst/gstutils.c: (gst_buffer_join):
* gst/gstutils.h:
gst_buffer_join() from 0.8.

* gst/gstpad.c: (gst_pad_accept_caps), (gst_pad_query),
(gst_pad_push), (gst_pad_push_event):
* gst/gstqueue.c: (gst_queue_change_state):
Don't queue buffers in basesink when we are flushing.
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.
Original commit message from CVS:
* gst/base/gstbasesrc.c: (gst_basesrc_change_state):
Remove implicit cast from gboolean to GstElementStateReturn;
make sure we still return failure in paused => ready case if
the parent class fails to change state and our own stop
vfunc succeeds.

* gst/gstelement.h:
Identify sinks by their flag to avoid overly complicated
checks (fow now).
Do state changes even for elements not reachable from the
sinks.
BaseSink is a sink now :)
Some more debugging info in the basesrc.
Original commit message from CVS:
* gst/base/gstbasesrc.c: (gst_basesrc_do_seek):
Discont event offset format should be GST_FORMAT_BYTES,
not GST_FORMAT_TIME.

2005-05-10 Andy Wingo <wingo@pobox.com>
* 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:
2005-05-09 Andy Wingo <wingo@pobox.com>
* gst/base/gstbasetransform.c (gst_base_transform_proxy_getcaps):
Intersect the peer's caps with our caps.
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.

Some fixes for the peer_get_caps() change.

Added draft for better selecting scheduling methods.
Make basesrc ignore length if the subclass does not support
it.
