Original commit message from CVS:
Based on a patch by: Sjoerd Simons <sjoerd at luon dot net>
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_buffer_alloc):
Don't passthrough buffer allocation too easily if the caps change.
This breaks when working in passthrough mode and upstream changes
it's caps. Fixes bug #526768.
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_prepare_output_buffer):
Also unset the GAP flag on buffers if we're working inplace but
the element is not GAP-aware.
Mark a comment as FIXME 0.11.

* gst/gstclock.h:
* libs/gst/base/gstbasesrc.h:
* libs/gst/base/gstbasetransform.c:
* libs/gst/check/gstcheck.c:
Small documentation fixes. Fixes#523978.
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_transform_size):
Print element name with g_warning() if there's a problem
with the unit size.

(gst_base_transform_prepare_output_buffer),
(gst_base_transform_set_gap_aware):
* libs/gst/base/gstbasetransform.h:
API: Add gst_base_transform_set_gap_aware() to control whether
the element correctly handles GST_BUFFER_FLAG_GAP or shouldn't
get buffers with this flag at all. Fixes#503231.
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_sink_event):
Work around the brokenness of the event vmethod in basetransform. Prefer
to return TRUE when the subclass returned FALSE (meaning don't forward
the event).
* libs/gst/base/gstbasetransform.h:
Clarify the docs.
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c: (gst_base_transform_chain):
Properly set the last_stop position on GstSegment. This will only happen
if there is a buffer to push out.
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_buffer_alloc):
always_in_place does not mean that the sink and source caps are the
same! Make sure we don't blindly proxy the buffer_alloc in this case.
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c: (gst_base_transform_activate):
Make sure streaming has finished before calling the ::stop() vfunc,
since that vfunc might clear state which is being used in the
streaming thread. This fixes a race that caused crashes in
audioresample when shutting down a pipeline (#420106).

(gst_base_transform_sink_eventfunc),
(gst_base_transform_handle_buffer), (gst_base_transform_chain),
(gst_base_transform_activate):
* libs/gst/base/gstbasetransform.h:
Add support for dropping buffers with custom GstFlowReturn.
Set DISCONT flags on outgoing buffers based on QoS, incomming DISCONT
buffers or dropped buffers.
* docs/libs/gstreamer-libs-sections.txt:
docs for new custom return code.
* plugins/elements/gstidentity.c: (gst_identity_transform_ip):
Use drop support in base class to implement drop-probability.
Original commit message from CVS:
* libs/gst/base/gstbasetransform.c: (gst_base_transform_init),
(gst_base_transform_check_get_range):
Implement a checkgetrange function instead of relying on the default
core behaviour that assumes we can operate in pull mode if we have a
getrange function. First step at fixing #385084.

* libs/gst/base/gstbasetransform.c (gst_base_transform_activate):
Factor start/stop into this private function instead of partially
in activate functions and partially in the change_state function.
Fixes setup before the element has changed from READY->PAUSED, as
is the case in pull-mode pipelines.
(gst_base_transform_sink_activate_push)
(gst_base_transform_src_activate_pull): Refactor to use
gst_base_transform_activate().
(gst_base_transform_change_state): Removed, not needed any more.
* libs/gst/base/gstbasesink.c (gst_base_sink_negotiate_pull):
Truncate before fixating.

* libs/gst/base/gstbasetransform.c (_GstBaseTransformPrivate):
(gst_base_transform_init, gst_base_transform_sink_activate_push)
(gst_base_transform_src_activate_pull):
Track the activation mode.
(gst_base_transform_setcaps): In pull mode, when activating the
src pad, after activating the sink pad, activate the sink pad's
peer, as discussed in part-negotiation.txt.
* libs/gst/base/gstbasesrc.h:
* libs/gst/base/gstbasesrc.c (gst_base_src_fixate): Add fixate

* libs/gst/base/gstbasesink.h: Reformat docs, add fixate vmethod.
* libs/gst/base/gstbasesink.c (gst_base_sink_pad_setcaps): In pull

(gst_base_sink_pad_fixate): Add a fixate function that calls the
new fixate vmethod.
(gst_base_sink_default_activate_pull): Rename from
gst_base_sink_activate_pull.
(gst_base_sink_negotiate_pull): New function, performs negotiation
in pull mode before calling ::activate_pull().
(gst_base_sink_pad_activate_pull): Actually call the activate_pull
vmethod instead of the default implementation. I have no idea how
this worked before. Negotiate before calling activate_pull.
Original commit message from CVS:
* gst/gstevent.h:
Add small comment.
* libs/gst/base/gstbasetransform.c:

Debug segment values *after* updating them as this is more

Original commit message from CVS:
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_buffer_alloc):
Check if requested caps are the same as the sinks caps IF
->have_same_caps is TRUE. If they are not, act as if have_same_caps
is FALSE.
This fixes the renegotiation issues stated in #352827.

Original commit message from CVS:
* libs/gst/base/gstbasetransform.c:
(gst_base_transform_buffer_alloc):
Even if we can't figure out the proper format to request downstream,
call buffer_alloc() downstream with the input parameters without setting
the caps on the srcpad. This will force negotiation in the chain
function.
Closes#350449
Original commit message from CVS:
