Original commit message from CVS:
* gst/base/gstbasetransform.c: (gst_base_transform_class_init),
(gst_base_transform_event), (gst_base_transform_eventfunc):
The event virtual method is now properly implemented, with a default
handler
Sub classes should call the parent_class event method. They should
return FALSE if they had a problem handling the given event, or don't
want GstBaseTransform to send that even downstream
* gst/elements/gstidentity.c: (gst_identity_class_init),
(gst_identity_init), (gst_identity_event),
(gst_identity_transform_ip), (gst_identity_set_property),
(gst_identity_get_property):
* gst/elements/gstidentity.h:
Added the single-segment boolean property.
If set to TRUE, it will output a single segment of data, starting from
0, will eat up all incoming newsegment, and modify the timestamp of the
buffers accordingly

(gst_event_parse_new_segment, gst_event_new_buffer_size)
(gst_event_parse_buffer_size, gst_ghost_pad_new_no_target):
Renamed from *_newsegment, *_buffersize, *_notarget.

listed above.

* check/gst/gstevent.c (create_custom_events): Check that
FLUSH_STOP is serialized.
* check/elements/identity.c (event_func):
* check/elements/fakesrc.c (event_func): No stream lock, the core
takes it.
* gst/base/gstbasetransform.c (gst_base_transform_event): No more
stream lock taking, yay.
* gst/gstevent.h (GST_EVENT_FLUSH_STOP): Marked as serialized to
ensure that core takes the stream lock.
* gst/base/gstbasesrc.c (gst_base_src_do_seek): Update for stream
lock name change.
* gst/base/gstbasesink.c (gst_base_sink_event): No need to take
the stream lock for EOS, NEWSEGMENT, or FLUSH_STOP, the core does
it already. For the flush start we do take it though so we get the
right preroll state change messages.
* gst/gstqueue.c (gst_queue_sink_activate_push): No need to take
the stream lock here, the core does it for us.
* gst/gstpad.h (GST_PAD_GET_STREAM_LOCK): Renamed from
GST_STREAM_GET_LOCK.
(GST_PAD_STREAM_LOCK, GST_PAD_STREAM_TRYLOCK)
(GST_PAD_STREAM_UNLOCK, GST_PAD_STREAM_UNLOCK_FULL)
(GST_PAD_STREAM_LOCK_FULL): Renamed from GST_STREAM_*.

* gst/gstobject.h (GST_OBJECT_GET_LOCK, GST_OBJECT_LOCK)
(GST_OBJECT_TRYLOCK, GST_OBJECT_UNLOCK): Renamed from
GST_GET_LOCK, etc.
* scripts/update-macros: New script. Run it on your files to
change GST_LOCK to GST_OBJECT_LOCK, and the same for UNLOCK as
well.
Original commit message from CVS:
* gst/base/gstbasetransform.c:
(gst_base_transform_prepare_output_buf),
(gst_base_transform_event):
Check if the caps are NULL, this can happen if the element
is shutting down and the pad caps are set to NULL.
Original commit message from CVS:
* gst/base/gstbasesink.c: (gst_base_sink_handle_object):
0 segment values are 0 in any format.

* gst/base/gstbasetransform.c:
(gst_base_transform_prepare_output_buf):
Ref the source pad caps while we need them.
Fixes (#321386)
Original commit message from CVS:
* gst/base/gstbasetransform.c:
(gst_base_transform_prepare_output_buf),
(gst_base_transform_handle_buffer):
Small cleanups.
If we're processing a buffer and need to allocate an output
buffer, we cannot accept a format change. If we did get a
format change, we have to alloc a buffer ourselves of the
right size.
Original commit message from CVS:
* gst/base/gstbasetransform.c: (gst_base_transform_transform_caps):
* gst/gstcaps.c: (gst_caps_intersect):
Don't call gst_caps_do_simplify - it doesn't respect order of caps
and it's not needed.
Original commit message from CVS:
* gst/base/gstbasetransform.c: (gst_base_transform_event):
Hold STREAM_LOCK while pushing newsegment or tag events as well.

(gst_capsfilter_init), (gst_capsfilter_transform_ip),
(gst_capsfilter_prepare_buf):
If the output pad has fixed allowed caps and input buffers
don't have any, set the fixed caps on outgoing buffers.
Original commit message from CVS:
* check/elements/identity.c: (GST_START_TEST):
Make the error a little clearer when the test fails because
identity made a copy of the buffer.

(gst_base_transform_set_in_place),
(gst_base_transform_is_in_place):
* gst/base/gstbasetransform.h:
Change BaseTransform to separate in_place operate from same_caps
output. in_place implies that the element can perform the transform
on incoming buffers in-place, even if the caps on the output are
different.
Sub-class elements can now implement special buffer allocation
methods for outgoing buffers if they wish to.
Big documentation addition.

* gst/gstelement.h (GstState): Renamed from GstElementState,
changed to be a normal enum instead of flags.
(GstStateChangeReturn): Renamed from GstElementStateReturn, names
munged to be GST_STATE_CHANGE_*.
(GST_STATE_CHANGE): Renamed from GST_STATE_TRANSITION, updated to
work with the new state representation.
(GstStateChange): New enumeration of possible state transitions.
Replaces GST_STATE_FOO_TO_BAR with GST_STATE_CHANGE_FOO_TO_BAR.
(GstElementClass::change_state): Pass the GstStateChange along as
an argument. Helps language bindings, so they don't have to use
tricky lock-needing macros like GST_STATE_CHANGE ().
* scripts/update-states (file): New script. Run it on a file to
update it for state naming and API changes. Updates files in
place.
* All files updated for the new API.

Handle the case where we are not negotiated more gracefully.
Original commit message from CVS:
* gst/base/gstbasetransform.c: (gst_base_transform_handle_buffer):
passthrough elements can even do inplace on non writable
buffers (as they don't touch them).
Original commit message from CVS:
* gst/base/gstadapter.c: (gst_adapter_flush):
Flushing out 0 bytes is ok for this function.
* gst/base/gstbasesink.c: (gst_base_sink_handle_object):

invalid.

fixes buffer_alloc proxying among other things.
* gst/base/gstbasetransform.c:
* gst/base/gstbasetransform.h:
Revert patch to gstbasetransform from 7-28 removing
delay_configure.
* gst/base/gstbasetransform.h (GstBaseTransformClass.get_size):
* gst/base/gstbasetransform.c (gst_base_transform_get_size):
Semantics changed, should return not the size of the output buffer
but the byte size of a buffer with a given caps.
* gst/base/gstbasetransform.c (gst_base_transform_getcaps): Better
debug object.
(gst_base_transform_configure_caps): Don't set out_size here: (in,
out) are not the pad caps until setcaps finishes.
(gst_base_transform_buffer_alloc): Proxy the buffer_alloc for the
not-in-place case as well. Deal with changing from in-place to
not-in-place within calling pad_alloc_buffer. Still a bit
concerned about the overhead here...

* 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.

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.
