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/base/gsttypefindhelper.c (gst_type_find_helper): Unref any remaining buffer.
Original commit message from CVS:
2005-06-27 Andy Wingo <wingo@pobox.com>
* gst/base/gsttypefindhelper.c (gst_type_find_helper): Unref any
remaining buffer.
* gst/gsttrace.c (gst_alloc_trace_list_sorted): New helper,
returns a sorted copy of the trace list.
(gst_alloc_trace_print_live): New API, only prints traces with
live objects. Sort the list.
(gst_alloc_trace_print_all): Sort the list.
(gst_alloc_trace_print): Align columns.
* gst/elements/gstttypefindelement.c:
* gst/elements/gsttee.c:
* gst/base/gstbasesrc.c:
* gst/base/gstbasesink.c:
* gst/base/gstbasetransform.c:
* gst/gstqueue.c: Adapt for pad activation changes.
* gst/gstpipeline.c (gst_pipeline_init): Unref after parenting
sched.
(gst_pipeline_dispose): Drop ref on sched.
* gst/gstpad.c (gst_pad_init): Set the default activate func.
(gst_pad_activate_default): Push mode by default.
(pre_activate_switch, post_activate_switch): New stubs, things to
do before and after switching activation modes on pads.
(gst_pad_set_active): Take a boolean and not a mode, dispatch to
the pad's activate function to choose which mode to activate.
Shortcut on deactivation and call the right function directly.
(gst_pad_activate_pull): New API, (de)activates a pad in pull
mode.
(gst_pad_activate_push): New API, same for push mode.
(gst_pad_set_activate_function)
(gst_pad_set_activatepull_function)
(gst_pad_set_activatepush_function): Setters for new API.
* gst/gstminiobject.c (gst_mini_object_new, gst_mini_object_free):
Trace all miniobjects.
(gst_mini_object_make_writable): Unref the arg if we copy, like
gst_caps_make_writable.
* gst/gstmessage.c (_gst_message_initialize): No trace init.
* gst/gstghostpad.c (gst_proxy_pad_do_activate)
(gst_proxy_pad_do_activatepull, gst_proxy_pad_do_activatepush):
Adapt for new pad API.
* gst/gstevent.c (_gst_event_initialize): Don't initialize trace.
* gst/gstelement.h:
* gst/gstelement.c (gst_element_iterate_src_pads)
(gst_element_iterate_sink_pads): New API functions.
* gst/gstelement.c (iterator_fold_with_resync): New utility,
should fold into gstiterator.c in some form.
(gst_element_pads_activate): Simplified via use of fold and
delegation of decisions to gstpad->activate.
* gst/gstbus.c (gst_bus_source_finalize): Set the bus to NULL,
help in debugging.
* gst/gstbuffer.c (_gst_buffer_initialize): Ref the buffer type
class once in init, like gstmessage. Didn't run into this issue
but it seems correct. Don't initialize a trace, gstminiobject does
that.
* check/pipelines/simple_launch_lines.c (test_stop_from_app): New
test, runs fakesrc ! fakesink, stopping on ::handoff via a message
to the bus.
(assert_live_count): New util function, uses alloc traces to check
cleanup.
* check/gst/gstghostpad.c (test_ghost_pads): More refcount checks.
To be modified when unlink drops the internal pad.

Original commit message from CVS:

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

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

tests/network-clock.scm: Commentary update.
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.

tests/network-clock.scm: Commentary update.
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.

Original commit message from CVS:

Make the error a little clearer when the test fails because

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.

tests/network-clock.scm: Commentary update.
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.

(gst_base_transform_configure_caps), (gst_base_transform_setcaps),

(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.

tests/network-clock.scm: Commentary update.
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.

as a matter of last resort. (Not actually implemented.)

as the existing pad caps, just update the pointer without calling
setcaps. Assert that caps is either NULL or fixed, as per the

Original commit message from CVS:

* 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

tests/network-clock.scm: Commentary update.
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.

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_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.

tests/network-clock.scm: Commentary update.
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.

* 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.

Original commit message from CVS:

Make the error a little clearer when the test fails because

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.

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.

Convert and store timestamps in stream time and running time, the

Use different window sizes for good and bad QoS observations so
we react to badness a little quicker.

The event virtual method is now properly implemented, with a default

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

If set to TRUE, it will output a single segment of data, starting from

gst/gstbus.c: Small documentation clarification about the signal watch.
Original commit message from CVS:
* gst/gstbus.c:
Small documentation clarification about the signal watch.

(gst_base_sink_wait_clock), (gst_base_sink_do_sync),
(gst_base_sink_perform_qos), (gst_base_sink_reset_qos),

Convert and store timestamps in stream time and running time, the
raw timestamps are not usefull, also document this better.
Use different window sizes for good and bad QoS observations so
we react to badness a little quicker.
Keep track of the amount of rendered and dropped buffers.
Send QoS timestamps in running time.

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/base/gsttypefindhelper.c (gst_type_find_helper): Unref any remaining buffer.
Original commit message from CVS:
2005-06-27 Andy Wingo <wingo@pobox.com>
* gst/base/gsttypefindhelper.c (gst_type_find_helper): Unref any
remaining buffer.
* gst/gsttrace.c (gst_alloc_trace_list_sorted): New helper,
returns a sorted copy of the trace list.
(gst_alloc_trace_print_live): New API, only prints traces with
live objects. Sort the list.
(gst_alloc_trace_print_all): Sort the list.
(gst_alloc_trace_print): Align columns.
* gst/elements/gstttypefindelement.c:
* gst/elements/gsttee.c:
* gst/base/gstbasesrc.c:
* gst/base/gstbasesink.c:
* gst/base/gstbasetransform.c:
* gst/gstqueue.c: Adapt for pad activation changes.
* gst/gstpipeline.c (gst_pipeline_init): Unref after parenting
sched.
(gst_pipeline_dispose): Drop ref on sched.
* gst/gstpad.c (gst_pad_init): Set the default activate func.
(gst_pad_activate_default): Push mode by default.
(pre_activate_switch, post_activate_switch): New stubs, things to
do before and after switching activation modes on pads.
(gst_pad_set_active): Take a boolean and not a mode, dispatch to
the pad's activate function to choose which mode to activate.
Shortcut on deactivation and call the right function directly.
(gst_pad_activate_pull): New API, (de)activates a pad in pull
mode.
(gst_pad_activate_push): New API, same for push mode.
(gst_pad_set_activate_function)
(gst_pad_set_activatepull_function)
(gst_pad_set_activatepush_function): Setters for new API.
* gst/gstminiobject.c (gst_mini_object_new, gst_mini_object_free):
Trace all miniobjects.
(gst_mini_object_make_writable): Unref the arg if we copy, like
gst_caps_make_writable.
* gst/gstmessage.c (_gst_message_initialize): No trace init.
* gst/gstghostpad.c (gst_proxy_pad_do_activate)
(gst_proxy_pad_do_activatepull, gst_proxy_pad_do_activatepush):
Adapt for new pad API.
* gst/gstevent.c (_gst_event_initialize): Don't initialize trace.
* gst/gstelement.h:
* gst/gstelement.c (gst_element_iterate_src_pads)
(gst_element_iterate_sink_pads): New API functions.
* gst/gstelement.c (iterator_fold_with_resync): New utility,
should fold into gstiterator.c in some form.
(gst_element_pads_activate): Simplified via use of fold and
delegation of decisions to gstpad->activate.
* gst/gstbus.c (gst_bus_source_finalize): Set the bus to NULL,
help in debugging.
* gst/gstbuffer.c (_gst_buffer_initialize): Ref the buffer type
class once in init, like gstmessage. Didn't run into this issue
but it seems correct. Don't initialize a trace, gstminiobject does
that.
* check/pipelines/simple_launch_lines.c (test_stop_from_app): New
test, runs fakesrc ! fakesink, stopping on ::handoff via a message
to the bus.
(assert_live_count): New util function, uses alloc traces to check
cleanup.
* check/gst/gstghostpad.c (test_ghost_pads): More refcount checks.
To be modified when unlink drops the internal pad.

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/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.

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/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.
