WARNING: Don't grab this updated unless you're really, REALLY sure.
Original commit message from CVS:
WARNING: Don't grab this updated unless you're really, REALLY sure.
WARNING: Wait for the next one.
Whole lotta changes here, including a few random bits:
examples/*/Makefile: updated to use `libtool gcc`, not just `gcc`
gst/
gstbuffer.h: updated to new flag style
gst.c, gstdebug.h: added new debugging for function ptrs
gstpipeline.c: set type of parent_class to the class, not the object
gstthread.c: ditto
plugins/
cdparanoia/cdparanoia.c: added an argument type, updated some defaults
cobin/spindentity.c: updated to new do/while loopfunction style
mp3encode/lame/gstlame.c: argument types, whole lotta lame options
tests/: various changes
Now, for the big changes: Once again, the scheduling system has changed.
And once again, it broke a whole bunch of things. The gist of the change
is that there is now a function pointer for gst_pad_push and gst_pad_pull,
instead of a hard-wired function. Well, currently they are functions, but
that's for debugging purposes only, they just call the function pointer
after spewing lots of DEBUG().
This changed the GstPad structure a bit, and the GstPad API as well.
Where elements used to provide chain() and pull() functions, they provide
chain() and get() functions. gst_pad_set_pull[region]_function has been
changed to get_pad_set_get[region]_function. This means all the elements
out there that used to have pull functions need to be updated. The calls
to that function have been changed in the normal elements, but the names
of the functions passed is still _pull[region](), which is an aesthetic
issue more than anything.
As for what doesn't work yet, just about anything dealing with Connections
is hosed, meaning threaded stuff won't work. This will be fixed about 12
hours from now, after I've slept, etc. The simplefake.c test works in
both cothreaded and chained cases, but not much else will work due to the
Connection problem. Needless to say, don't grab this unless you *need*
these features *now*, else wait to update this stuff until tomorrow.
I'm going to sleep now.

Simplify pad activation.
Added function to check if pull_range can be performed.
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.
Make identity subclass the base transform.

gst/gstquery.h
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.

Simplify pad activation.
Added function to check if pull_range can be performed.
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.
Make identity subclass the base transform.

Simplify pad activation.
Added function to check if pull_range can be performed.
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.
Make identity subclass the base transform.

Simplify pad activation.
Added function to check if pull_range can be performed.
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.
Make identity subclass the base transform.

Original commit message from CVS:
* 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_pad_call_get_function):
* gst/gstpad.h:
add gst_pad_call_chain_function and gst_pad_call_get_function for
scheduler interaction. They are required because of the changes
above.

* gst/schedulers/gstoptimalscheduler.c:
(get_group_schedule_function), (pad_clear_queued),

use the new functions instead of calling get/chain-functions
directly.
