When we have an input buffer with caps and when those caps are different from
the caps we want, only then make a writable copy of the input buffer as the
output buffer and set the caps on that output buffer. This avoids some cases
where we took a subbuffer for setting caps that were the same.

* plugins/elements/gstcapsfilter.c: (gst_capsfilter_class_init),

More G_OBJECT macro fixing. Also Fix some details on the plugin-stamp
section.
Original commit message from CVS:
* plugins/elements/gstcapsfilter.c: (gst_capsfilter_prepare_buf):
The caps intersection algorithm can produce multiple copies of the
caps. Until that is fixed, we need to simplify the result to be
sure whether the allowed caps are fixed or not.
* plugins/elements/gstqueue.c: (gst_queue_init),
(gst_queue_bufferalloc), (gst_queue_acceptcaps),
(gst_queue_push_one):
Proxied buffer alloc should not set the caps on the source pad.
When pushing buffers, we always accept the caps change that triggers.
This prevents negotiation errors caused by caps changing mid-stream
and then being refused on our source pad (because upstream is now
refusing those caps).

Change BaseTransform to separate in_place operate from same_caps

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.

changed.

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...
Original commit message from CVS:
* gst/elements/gstcapsfilter.c: (gst_capsfilter_class_init),
(gst_capsfilter_set_property): Allow NULL as possible value
for filter_caps property, indicating GST_CAPS_ANY.
Original commit message from CVS:
* gst/elements/gstcapsfilter.c: (gst_capsfilter_set_property):
Free existing caps if the capsfilter changes. Add a FIXME about
setting those caps on the pads.
* gst/gstutils.c: (gst_element_get_compatible_pad), (ghost_up):
Before adding a ghost pad to a parent bin, check that there isn't
already one for the element on the bin. Prevents infinite recursion
when using decodebin in parse pipelines. Andy says he'll rewrite the
way this works anyway, so ignore the hack.

have been checked in a long time ago.
