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:
2005-05-09 Andy Wingo <wingo@pobox.com>
* gst/gstiterator.h: Add some includes.
* gst/gstqueryutils.h: Include more headers.
* gst/gstpad.h:
* gst/gstpad.c (gst_pad_query_position): New routine, replaces
some uses of gst_pad_query.
* gst/gstqueryutils.c: Build fixes. Make parse functions ignore
NULL out parameters.
(gst_query_new_position): New proc, allocates a new position
query.
* gst/Makefile.am (libgstreamer_@GST_MAJORMINOR@_la_SOURCES): Add
gstqueryutils.c to the build.
* gst/gststructure.c (gst_structure_set_valist): Implement with
the generic G_VALUE_COLLECT.
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.
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

Error out when pulling inactive or flushing pads.
Removed const from refcounted types as it does not make sense.
Simplify pad templates in basesink
Added base class for simple 1-to-1 transforms.

scheduling updates soon.
Moved events out of data stream.
Simplified GstEvent types.
Added return values to push/pull.
Removed clocking from GstElement.
Added prototypes for state change function for next merge.
Removed iterate from bins and state change management.
Fixed some elements, disabled others for now.
Fixed -inspect and -launch.
Added check for GstBus.
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:

Original commit message from CVS:
2004-07-14 Andy Wingo <wingo@pobox.com>
* gst/gsttag.c: Add a tag merge func for pointers. The header was
there all along, but the function wasn't. (guile-gstreamer's build
system uses the address of the function -- I wasn't actually
trying to use this.)
2004-07-13 Andy Wingo <wingo@pobox.com>
* gst/gstpad.c (gst_pad_try_set_caps): Naive link functions (such
as gst_pad_proxy_pad_link) just link to every other pad when they
are called. In the case where the graph has cycles, this will mean
that a call to try_set_caps will recurse. Allow this recursion
and return OK, while we wait for the first try_set_caps to give a
proper return value.
(gst_pad_link_call_link_functions): Since this function is the
only one to set the NEGOTIATING flag on a pad, if the flag is set
it means that the link functions have indirectly recursed. If this
happens, error out to avoid infinite recursion and an eventual
SEGV.
(gst_real_pad_class_init): Remove a crufty GtkObject comment.
(gst_pad_proxy_getcaps): Intersect the result with the template
caps to ensure that the return value is valid.
2004-07-11 Andy Wingo <wingo@pobox.com>
* gst/gstdata.c (gst_data_is_writable): s/>=/>/. If there is only
one refcount, the calling function is the owner of the buffer.

* gst/gstpad.c: (gst_pad_set_active), (gst_pad_link_new),
(gst_pad_link_free), (gst_pad_link_try), (_invent_event),
(gst_pad_pull):
implement enforcing discont events before buffers are passed. This
allows state changes of only some elements and later correctly going
on where they left off (or in short: you can now set audio sinks to
NULL to release the device when the pipeline is paused)
* gst/gstpad.c: (gst_pad_call_chain_function),

* gst/gstpad.h:
add gst_pad_call_chain_function and gst_pad_call_get_function for

above.

to use new GST_PTR_FORMAT.
* gst/gstelement.h: deprecate function factory macros
GST_ELEMENT_QUERY_TYPE_FUNCTION(), GST_ELEMENT_EVENT_MASK_FUNCTION().
These are our last variadic macros that can't be replaced with
inlines. Celebrate! Also fix a typo in an #ifdef that was
attempting to deprecate gst_element_clock_wait().

that I added a few weeks ago.

Copy over srcnotify, sinknotify when calling old pad_link
functions. Add new is_negotiated() function.
* gst/gststructure.c: (gst_structure_copy):
Fix an incredibly stupid bug that should have been noticed
weeks ago. _copy() returned the argument, not the new copy.
Original commit message from CVS:
* gst/elements/gstaggregator.c:
* gst/elements/gsttee.c:
Use gst_pad_proxy_getcaps().
* gst/gstpad.c:
* gst/gstpad.h:
Add gst_pad_proxy_getcaps(), which filter elements can use
as a generic getcaps implementation.
Fix gst_pad_get_allowed_caps(). It just wasn't doing what
was advertised.
Original commit message from CVS:
* gst/gstpad.c:
Rearrange/rewrite much of the pad negotiation code, since it
resembled pasta. This actually changes the way some
negotiation works, since the previous code was inconsistent
depending on how it was invoked. Add (internal) structure
GstPadLink, which is used to hold some information (more in
the future) about the link between two pads. Fixes a number
of bugs, including random lossage of filter caps when the
initial negotiation is delayed. A few functions are still
unimplemented.
* gst/gstpad.h:
Add GST_PAD_LINK_{SUCESSFUL|FAILED}() macros. Please use
these when testing GstPadLinkReturn values instead of comparing
directly.
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
