The name `gst_element_get_request_pad()` is confusing to people
learning GStreamer. `gst_element_request_pad_simple()` aims at
providing the exact same functionality, while making it more
explicit it is a simplified `gst_element_request_pad()`.
`gst_element_request_pad_simple()` is consistent with other
functions such as `gst_element_seek_simple`.
This commit deprecates `gst_element_get_request_pad()` so that a
compilation warning is emitted when used and incite developers
to use the more explicit `gst_element_request_pad_simple()`.

These can be passed to gst_type_mark_as_plugin_api, to inform
plugin cache generation.
For now a single flag is specified, "IGNORE_ENUM_MEMBERS", it
can be used for dynamically generated enums to avoid documenting
environment-specific enumeration members. An example is
GstX265EncTune.
Checking the current element's state when we're adding pads to
the parent element is checking the wrong thing.
Silences a 'attempting to add an inactive pad to a running element'
warning when adding a ghost pad to a running parent bin of the parent
bin of the element.

Adds tests for gst_element_get_compatible_pad for when it has to
request pads.
Note that these tests don't cover the case when it has to request
a pad that already exists.

This specifies if a given taglist applies to the complete
medium or only this specific stream. By default a taglist
has a stream scope.
Fixes bug #677619.
Remove the getcaps function on the pad and use the CAPS query for
the same effect.
Add PROXY_CAPS to the pad flags. This instructs the default caps event and query
handlers to pass on the CAPS related queries and events. This simplifies a lot
of elements that passtrough caps negotiation.
Make two utility functions to proxy caps queries and aggregate the result. Needs
to use the pad forward function instead later.
Make the _query_peer_ utility functions use the gst_pad_peer_query() function to
make sure the probes are emited properly.
Make a new GstPadProbeInfo structure and pass this in the probe callback. This
allows us to add more things later and also allow the callback to replace or
modify the passed object.
Make a separate cookie to detect chancges in the list of probes and keeping
track of what hooks have been invoked yet.
Remove the requirement to have probes on srcpads in push mode and sinkpads in
pull mode.
Add some more debug.
Keep track of what callbacks got executed. If no callback is called and we are a
blocking pad, let the item pass. This allows you to block pads on selected
items only.
Explicitly have an UPSTREAM and DOWNSTREAM PadProbeType. This allows you to only
block the pad on upstream or downstream items.
Add convenience macros to only block on downstream/upstream items.
Better now than later in the cycle. These might come in handy:
sed -i -e 's/GstProbeReturn/GstPadProbeReturn/g' `git grep GstProbeReturn | sed -e 's/:.*//' | sort -u`
sed -i -e 's/GST_PROBE_/GST_PAD_PROBE_/g' `git grep GST_PROBE_ | sed -e 's/:.*//' | sort -u`
sed -i -e 's/GstProbeType/GstPadProbeType/g' `git grep GstProbeType | sed -e 's/:.*//' | sort -u`
Keep track of installed number of probes to shortcut emission.
Allow NULL callbacks, this is useful for blocking probes.
Improve probe selection based on the mask, an empty mask for the data or the
scheduling flags equals that all probes match.
Add some more debug info.
Don't check the flushing flag in the probe callback handler, this needs to be
done before calling the handler.
Fix blocking probes.
Fix unit tests
GMP only uses "unsigned long int", which is 32 bit
on 32 bit architectures and can't hold a guint64.
This resulted in false unit test failures on 32 bit architectures.
Fixes bug #595133.
This tests 100000 random multiplications/divisions of all scaling
function variants and compares the result with the result that is
generated by GMP on the same input.
For this check for GSL and GMP during configure but only use
it for this single unit test.
Testing functions were provided by Kipp Cannon <kcannon@ligo.caltech.edu>
This will be mostly useful in all elements that have some kind of internal
seek/index table. Currently almost all of them (or even all of them)
are using a linear search although the used array is already sorted,
wasting some CPU time without good reason.
Fixes bug #573623.
Original commit message from CVS:
* tests/check/gst/gstutils.c: (probe_do_nothing), (data_probe),
(buffer_probe), (event_probe), (GST_START_TEST):
We now see 3 events go through our pad, since basesink now sends
upstream latency events.
Original commit message from CVS:
Based on patch by: José Alburquerque <jaalburqu at svn dot gnome dot org>
* gst/gstutils.c: (gst_pad_add_data_probe),
(gst_pad_add_data_probe_full), (gst_pad_add_event_probe),
(gst_pad_add_event_probe_full), (gst_pad_add_buffer_probe),

* gst/gstutils.h:
* docs/gst/gstreamer-sections.txt:
* win32/common/libgstreamer.def:
Add gst_pad_add_*_probe_full() functions with a notify callback that
lets the caller free the data it passes to the probe functions. This
is useful for bindings such as gst-python or gstreamermm (#526814).
API: gst_pad_add_data_probe_full
API: gst_pad_add_buffer_probe_full
API: gst_pad_add_event_probe_full
* tests/check/gst/gstutils.c:
Add minimal unit test to make sure freeing the data actually works
as expected.
* tests/benchmarks/.cvsignore:
Random cvsignore addendum.
Original commit message from CVS:
* gst/gst.c:
_gst_trace_on is already provided by gsttrace.h, no need to declare
it ourselves.
* docs/libs/gstreamer-libs-sections.txt:
Add 'buffers', 'check_cond' and 'check_mutex' from libgstcheck
and remove strange tcase_add_test which is outputting a warning.
* libs/gst/check/gstcheck.c:
* libs/gst/check/gstcheck.h:
Properly declare 'buffers', 'check_cond', 'check_mutex' extern
and define them in gstcheck.c instead of having every .c file whcih
includes gstcheck.h be defining its own copy and relying on symbol
interposing to marry them all, which doesn't work on Solaris.
* tests/check/elements/identity.c: (GST_START_TEST):
Don't define 'buffers' locally, it comes from libgstcheck.
* tests/check/generic/sinks.c: (send_buffer):
Fix type of variable (GstFlowReturn, not GstStateChangeReturn)
* tests/check/gst/gststructure.c: (GST_START_TEST):
* tests/check/gst/gstsystemclock.c: (GST_START_TEST):
* tests/check/gst/gstutils.c: (GST_START_TEST):
* tests/check/gst/gstvalue.c: (GST_START_TEST):
Add a bunch of casts to make various constants fit the types
they're being assigned to.
Original commit message from CVS:
* gst/gstutils.c: (gst_util_set_value_from_string):
Fix memleak (#351502).
* tests/check/gst/gstutils.c: (GST_START_TEST), (gst_utils_suite):
Add unit test for most of gst_util_set_value_from_string()
(not that one would want to encourage use of this function).
Original commit message from CVS:
Patch by: Antoine Tremblay <hexa00 at gmail com>
* gst/gstutils.c: (gst_element_unlink):
Free iterator when done (#347311).
* tests/check/gst/gstutils.c: (GST_START_TEST), (gst_utils_suite):
And add a test case for this.
