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_get_unit_size),
(gst_base_transform_buffer_alloc),
(gst_base_transform_handle_buffer), (gst_base_transform_chain),
(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.
