* gst/gstclock.h (GstClock): Add rate and offset properties,
preserving ABI stability. Add rate/offset accessors. Will file bug
for the freeze break.
* gst/gstclock.c (gst_clock_adjust_unlocked): Implement using rate
and offset, trying to keep precision and avoiding
underflow/overflow.
(gst_clock_set_rate_offset, gst_clock_get_rate_offset): New
functions. Make gst_clock_set_time_adjust obsolete.
(gst_clock_set_time_adjust): Note that this function is obsolete.
Will file bug soon.
* gst/base/gstbasetransform.h: Make the ABI-stability hack
greppable by using GST_PADDING-1+1.
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_event):
* gst/base/gstbasetransform.h:
Parse newsegment correctly in basetransform
* gst/elements/gstidentity.c: (gst_identity_transform_ip):
Sync to clock using updated segment values.
Original commit message from CVS:
* gst/base/gstbasesink.c: (gst_base_sink_handle_object),
(gst_base_sink_do_sync), (gst_base_sink_get_position):
Some more debugging.
* gst/base/gstbasetransform.c: (gst_base_transform_finalize),
(gst_base_transform_init), (gst_base_transform_buffer_alloc),
(gst_base_transform_event), (gst_base_transform_getrange),
(gst_base_transform_chain):
* gst/base/gstbasetransform.h:
Fix debugging,
Protect transform and concurrent buffer alloc with a new lock.
Try not to break ABI/API.
Original commit message from CVS:
* check/gst-libs/controller.c:
Header include fix.
* gst/base/gstbasetransform.c:
(gst_base_transform_default_prepare_buf),
(gst_base_transform_handle_buffer):
* gst/base/gstbasetransform.h:
Some more basetransform changes and fixes to enable sub-classes
that modify buffer metadata only.
* gst/elements/gstcapsfilter.c: (gst_capsfilter_class_init),
(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.
* docs/gst/gstreamer-sections.txt:
New symbols in gstbasetransform.h
* gst/base/gstbasetransform.c: (gst_base_transform_class_init),
(gst_base_transform_init), (gst_base_transform_transform_size),
(gst_base_transform_configure_caps), (gst_base_transform_setcaps),
(gst_base_transform_default_prepare_buf),

(gst_base_transform_change_state),
(gst_base_transform_set_passthrough),
(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/elements/gstcapsfilter.c: (gst_capsfilter_transform_ip):
* gst/elements/gstelements.c:
Changes for basetransform modifications.
* gst/elements/Makefile.am:
* gst/elements/gstfdsrc.c: (gst_fdsrc_init), (gst_fdsrc_create):
Compile fix. Extra debug output.

(gst_base_transform_get_unit_size),
(gst_base_transform_buffer_alloc), (gst_base_transform_event),
(gst_base_transform_handle_buffer):
* gst/base/gstbasetransform.h:
handle and store timed NEWSEGMENT events so that subclasses that
calculate time by counting samples have a segment_start time they
need to add to their timestamps - see audioresample

use gboolean return values and pointers to size so we can use the
full GST_BUFFER_SIZE range (guint) for buffer sizes
use GstPadDirection for transform_caps
* gst/base/gstbasetransform.h:
rename get_size to get_unit_size since that's what it is

Original commit message from CVS:
2005-08-04 Andy Wingo <wingo@pobox.com>
* gst/elements/gstcapsfilter.c: Reimplement using basetransform,
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...

* gst/base/gstbasetransform.h:
Make passthrough work using the bufferpools.
Changed API a bit, subclasses have to write into a buffer
provided by the base class.
More debug info in nego functions.
* gst/elements/gstidentity.c: (gst_identity_init),
(gst_identity_transform):
Port to new base class.
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.

Added start/stop methods to transform base class so subclasses
don't need to deal with state changes even.

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.
