... instead of returning a reference to a global instance. The caller might
want to change the global instance otherwise, which causes funny effects like
all global instances being changed and at the same time nothing in the caps
being changed.
As the caps might be immutable while we do this we have to do some magic
with atomic operations.

Keep an extra write ref on the control socket. This ensures that we
avoid a read/write on the socket when going from non-empty->empty->not-empty.
We remove the write ref only when we actually are empty and we need to
wait for flushing or a new buffer.
This makes the bufferpool benchmark about 30% faster than the pure
malloc implementation.
This way we make sure that a) the lock is always taken when checking
the cookie and calling the iterator's next functions and b) it is
not taken while calling any of the iterator filter functions.

events_foreach adds an extra ref when giving the event to the
user function. In case it was unrefed by the user, this extra ref
disappeared, but events_foreach still should unref again to
lose its own ref before removing the event from the array.

Make this work again:
audiotestsrc ! tee name=t t.src_0 ! queue ! fakesink t.src_1 ! queue ! fakesink
and this fail again:
audiotestsrc ! tee name=t t.src_1 ! queue ! fakesink t.src_0 ! queue ! fakesink
as tee just counts itself and does not care about the pad names we request
from it.
This allows blocking a pad, add a new blocking probe, removing
the first probe and then having the second probe called. Which
could then decide that data-flow should actually continue
instead of blocking now.
https://bugzilla.gnome.org/show_bug.cgi?id=721289
Also only check the data types for non-IDLE probes. When we
are idle, we have no data type obviously.
Previously we were calling IDLE probes during data flow whenever
a non-blocking probe would be called. The pad was usually not idle
at that time.
Checking twice the lower bound is great (you never know, it might change
between the two calls by someone using emacs butterfly-mode), but it's a bit
more useful to check the higher bound are also identical.

Make a new flag on the pad that tweaks the default behaviour of the
accept-caps function. By default it will check for a subset of the
query-caps result but this is not always desirable. The query-caps
result contains all the constraints to make a good caps decision
upstream but sometimes, like for parsers, not all the constrained caps
fields are known upstream and then a subset check would fail. Switching
to an intersection makes this work again.

Older versions of flex (before 2.5.36) don't add the prototype, so it must
be added manually. We can't check by the version number, because Debian/Ubuntu
patched it into their 2.5.35 at some point.
This reverts commit 8162a583a4.
Automatically copying the sticky events makes it impossible for apps
and elements to filter the events with event probes. This causes
regressions (See #719437). The best option is to let the app/element
copy and filter the events themselves after the ghostpad target is
set.
Update the sticky events on SRC ghostpads when retargeting. This ensures
that the ghostpad has the exect same sticky events as the target pad. We
don't want to do this for SINK ghostpads, they got the events from
downstream and we don't want to overwrite them with the target pad
events.

It was unintuitive that GstContext was actually a list of different
contexts. GstContext now is only a type string and a structure to
contain the actual context.
Non-persistent contexts are removed when elements go back
to NULL state, persistent contexts are not. Applications
most likely want to set persistent contexts.
Since the default number of max unused threads in GThreadPool has been

If all stream-start messages had a group id (for backwards compatibility),
we only consider a stream started if all had the same group id.
In 2.0 we should make the group id mandatory.
All streams that have the same group id are supposed to be played
together, i.e. all streams inside a container file should have the
same group id but different stream ids. The group id should change
each time the stream is started, resulting in different group ids
each time a file is played for example.

API: GST_PLUGIN_STATIC_REGISTER()
Based on a patch by Håvard Graff <havard.graff@tandberg.com>.
This now allows GST_PLUGIN_DEFINE() to create a static plugin if
GST_PLUGIN_BUILD_STATIC is defined. The resulting plugin can be
statically linked or dynamically linked during compilation but
can't be dynamically loaded during runtime.
Also adds GST_PLUGIN_STATIC_DECLARE() and GST_PLUGIN_STATIC_REGISTER(),
which allows to register a static linked plugin easily.
It is still required to manually register every single statically linked
plugin from inside the application as this can't be automated in a portable
way.
A new configure parameter --enable-static-plugins was added that allows
to build all plugins we build here as static plugins.

Don't use snprintf(), but use sprintf instead and do our own

%n in a format string if the string is in writable memory, and
here the format string is always in writable memory since we

with _FORTIFY_SOURCE=2, which seems to be the case on some
distros/systems). On the upside, we now use the sprintf code path

This is equal to any other caps features but results in unfixed caps. It
would be used by elements that only look at the buffer metadata or are
currently working in passthrough mode, and as such don't care about any
specific features.
These are meant to specify features in caps that are required
for a specific structure, for example a specific memory type
or meta.
Semantically they could be though of as an extension of the media
type name of the structures and are handled exactly like that.
Elements should override GstElement::set_context() and also call
gst_element_set_context() to keep this context up-to-date with
the very latest context they internally use.
When flushing, it is expected that upstream will send a SEGMENT
event afterwards.
This also avoids stray SEGMENT events from coming through after a
flush.
Unref the allocator *after* we have freed the memory. We also need to keep

The function init_pre() in gstreamer/gst/gst.c calls setlocale(LC_ALL, ""),
which sets the locale to the values specified in the environment. This is
wrong for two reasons:
1. It is absolutely not the task of a library to decide on the correct locale
for a program. Some programs change the locale for various (good or bad)
reasons, and libraries should respect that. Programs where GStreamer's
overwriting of the locale causes bugs include Emacs [1, 2], Sublime Text [3],
and Lua [4].

[3] http://www.sublimetext.com/forum/viewtopic.php?f=3&t=8543
[4] https://github.com/pavouk/lgi/issues/19
Note that setting the locale can cause problems for programs that are not even
linked against GStreamer. In the case of Emacs, for example, GStreamer seems
to be initialized through GTK via libcanberra.
2. Setting the locale is not thread-safe, and therefore should not be done in a
library.

It's usually not a problem if a query fails if there's no peer,
especially as it will happen during pad linking (caps query)
quite often and spams the logs.
If we try to push sticky events but a probe dropped them, we don't mark
the event as received and mark the pad as PENDING_EVENTS. This ensures
that we resend the event the next time. For this we need to let the
custom flow return from the probe trickle up to
gst_pad_push_event_unchecked() so that we can differentiate between
OK and DROPPED probe returns.
First check that we can actually register the implementation before
making a GstMetaInfo. If we can't register we would otherwise end
up with an undefined type and an invalid GstMetaInfo.
It's possible that type registration fails because another metadata
with the same implementation name was already registered.
Fixes negotiation taking a ridiculous amount of
time (multiple 10s of seconds on a core2) when
there are duplicate entries in lists.
Could have a negative performance impact on other
scenarios because we now have to iterate the
dest list to avoid duplicates, but we don't
have a lot of lists any more these days, and
they tend to be small anyway. The negatives
are hopefully countered by the positive effects
of reducing the list length early on in the
process. And in any case, it's the right thing
to do.

Facilitate GstBuffer -> GstSample transition for some tags,
could be hard to catch otherwise when creating tags, since
it'll only be apparent later when someone tries to read the

We usually first create the stream_id for the stream_start event and then add
the pad to the element. This means that this functions should work when there
are no pads on the element yet.
Recheck for sticky events after doing a pad block because the pad block could
have caused a relink and then we need to resend the events to the newly linked
pad.
Fixes things like switching of visualisations.
The duration should be re-queried via a query using the

This is because we need to be able to signal different TOCs
to downstream elements such as muxers and the application,

Remove the user_data from the alloc vmethod. Subclasses that implement a new
alloc function can also implement their own vmethod to pass extra arguments. We
can then also require that custom allocators implement an alloc function so that
gst_allocator_alloc() always works.
So we can serialise/deserialise taglists inside structures,
which used to work automagically before because GstTagList
was just a typedef to GstStructure (same for the GType),

explicit functions for this.

make sure to clear the flags in gst_pad_activate_mode(), which should

Make a new gstallocator.c file. Make a GstAllocator subclass for the default

Clear the initial floating ref in the init function for

using GstObject features for debugging, we'll just do
it like this.
This should also fix some problems with bindings, which
seem to get confused when they get floating refs from

have a 'transfer full' return type). This works now:

This re-uses existing code and makes sure we properly serialise
and deserialise datetimes where not all fields are set (thus
fixing some warnings when serialising such datetimes).
We still don't do that in _to_iso8601_string() though, since
this will probably mostly be used in tags, where it doesn't
matter so much and the microsecond argument might not be
well-received by some tag readers.
When we fail to parse the number of seconds, reset the value to -1
instead of passing some error value as seconds. Also, we can still
try to parse timezone information.
Expose the GstAllocation structure and provide an _init function. This makes it
easier to make 'subclasses' of the allocator that contain more info.
It also allows us to expose the flags on the allocator miniobject.
Make a flag to note that the allocator uses a custom alloc function.
Make it possible to add API specific flags to the ALLOCATION query. This makes
it possible to also check what kinds of subfeatures of the metadata API are
supported.
Add a method that memory implementations can call to initialize the standard
GstMemory structure.
Move the parent handling in the _free handler.
Rearrange some internal function parameters so that the order is consistent.
Add more memory examples
Move the locking methods from GstMemory to GstMiniObject.
Add a miniobject flag to enable LOCKABLE objects. LOCKABLE objects can
use the lock/unlock API to control the access to the object.
Add a minobject flag that allows you to lock an object in readonly mode.
Modify the _is_writable() method to check the shared counter for LOCKABLE
objects. This allows us to control writability separately from the refcount for
LOCKABLE objects.
The NO_SHARE flag does not influence the exclusiveness of the buffer initially
but only if a _share operation can be done. Otherwise, we would not be able to
WRITE map a buffer memory because it would have a share count of at least 2.
We implement the locking in gst_memory_map with the lock flags, make matching
flags the same number so that we can use the map flags directly as lock flags.
Expose the internally used methods for locking and unlocking the object. Pass
the access mode to the unlock function for extra checks and because we need it
for the EXCLUSIVE locks.
Make some new defines to specify the desired locking.
Add a new EXCLUSIVE lock mode which will increment the shared counter. Objects
with a shared counter > 1 will not be lockable in WRITE mode.
Improve parallel installability in setups like jhbuild by
providing versioned variants of some environment variables:
GST_REGISTRY_1_0
GST_PLUGIN_PATH_1_0
GST_PLUGIN_SYSTEM_PATH_1_0
GST_PLUGIN_SCANNER_1_0
will now be checked before checking the unversioned ones.

We added a minimum length of three letters originally so we would
fail to recognise DOS/Windows-style filenames as valid URIs (as we
should). Two should be just fine as well.
Make GstSeekFlag to GstSegmentFlag conversion explicit, and
set only those seek flags in the segment flags which are
mapped. This makes sure we don't have extraneous flags
littering our segment flag field, which also fixes the
debug printing/serialisation of segment events in the
debug log.
Visual C++ does not have isnan(), so add fallback to
math-compat.h (could use _isnan() in this case, but
this makes it work for all cases where isnan is missing).
https://bugzilla.gnome.org/show_bug.cgi?id=679112
Make a gst_buffer_append_region() function that allows you to append a memory
region from one buffer to another. This is a more general version of
gst_buffer_append().
If we have a file called Foo\Bar.ogg, there is no way to pass
that filename properly to filesrc in gst_parse_launch(), since
gst_parse_unescape() will just unescape \x to x.
Not cherry-picking this into 0.10 since there are apparently
apps that work around this problem and which would break if
we fixed it there too.
https://bugzilla.gnome.org/show_bug.cgi?id=673319
Take into account that not all fields might be valid (though they
are valid in the GDateTime structure). But we should just return
unordered if the set fields don't match. Also, don't check
microseconds when comparing datetimes, since we don't serialise
those by default if they're available. This ensures date times are
still regarded as equal after serialising+deserialising.
Some tag parsers and writers use same datetime format based on ISO 8601.
We can reduce some code by creating some general functions for it.
API: gst_date_time_to_iso8601_string()
API: gst_date_time_new_from_iso8601_string()
https://bugzilla.gnome.org/show_bug.cgi?id=678031
Now that TOCs are refcounted and have a GType, we can just
stuff a ref of the TOC directly into the various toc
event/message/query structures and get rid of lots of
cracktastic GstStructure <-> GstToc serialisation and
deserialisation code. We lose some TOC sanity checking
in the process, but that should really be done when
it's being created anyway.
Let's keep it simple for now:
gst_toc_setter_reset_toc() -> gst_toc_setter_reset()
gst_toc_setter_get_toc_copy() -> removed
gst_toc_setter_get_toc() -> returns a ref now
gst_toc_setter_get_toc_entry_copy() -> removed,
use TOC functions instead
gst_toc_setter_get_toc_entry() -> removed,
use TOC functions instead
gst_toc_setter_add_toc_entry() -> removed,
to avoid problems with (refcount-dependent)
writability of TOC; use TOC functions instead
So mini objects don't have to poke into the GstMiniObject part
of the structure. Saves lines of code, and seems slightly cleaner.
We don't have proper OO hierarchies or methods here after all.
These changes are to clean up syntax issues such as missing colons,
missing spaces, etc., and minor issues such as argument names in
headers not matching the implementation and/or documentation.
When 2 weak refs are added, the array is not resized big enough.
Simplify the weak ref handling code.
Free memory when we remove all weak refs.
Allow installing the same weak ref multiple times, like in gobject.
The size field is used by subclasses to store the total allocated size of the
memory for this miniobject. Because miniobject doesn't really do anything with
this field we can move it to the subclasses.
Add the running-time of the buffer that caused the async operation to complete
to the async-done message.
Update bin to handle the new async-done message.
Use the new RESET_TIME message to reset the start-time of the pipeline to the
requested time.
Make basesink request a new running-time when the flush-stop message tells it to
insteasd of waiting for preroll.
Add a new message to reset the pipeline running_time. Currently reseting the
pipeline can only be requested in the async_done message which means that the
pipeline needs to be prerolled. It is better to move this to a separate message.
Remove constructors we don't want:
gst_date_time_new_ymd_h() because we don't want to
support hour-only for now;
gst_date_time_new_ymd_hm() because we don't want to
add constructors with time info where the caller doesn't
have to think about what timezone the time is in.
Lots of compulsive clean-up. Docs fixes. Replace
has_minute() and has_hour() with has_time().
In order to deserialise and re-serialise dates and date times
from tags properly, we need to be able to express partial
dates (e.g. YYYY or YYYY-MM) and date times.
We only support partial date times where all the more
significant fields above the first unset field are set
(e.g. YYYY-00-DD is not supported).
Calling _get_foo() when foo is not set is not allowed
any more, callers need to check which fields are set
first.

Make the gst_bin_remove_func more like the add_func. Check if the element we try
to remove from the bin has the bin as the parent and set the parent flag to NULL
immediately, this allows us to avoid concurrent remove operations without using
the UNPARENTING element flag. After we unparented the element from the bin, we
update the bin state and remove the element from the list. Finally we unlink
all the pads.
This avoids a race condition where the element could still claim to have the
bin as the parent while the bin didn't have a pointer to the element anymore.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=647759
In the dispose handler we first need to release all the request pads and then
remove the remaining pads. This is because it is possible that releasing the
request pad might also cleanly remove some of the other dynamic pads, like
what rtpsession does.
https://bugzilla.gnome.org/show_bug.cgi?id=677436
Context: Latency configuration should not be
messed up because of not-linked pads. In general,
one return FALSE on latency distribution causes
the "overall" pipeline latency configuration to
fail. This shows up as noise in logs (warning).
Conflicts:
gst/gstpad.c
Otherwise a pipeline where one sticky event fails to be sent will
never forward EOS events downstream. This can cause pipelines to
wait forever for EOS on errors.
The linking behaviour of external variables that are not initialized
in the compilation unit where they are defined is undefined. On OS X
this causes a linking failure when statically linking GStreamer.
When the bin does an upward state change, try to avoid doing a downward state
change on the child and vice versa.
Add some more unit tests for this fix.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=621833
Make GstPluginFeature opaque until we have time to
clean it up a little. Only GstElementFactory and
GstTypefindFactory derive from it, and they are
opaque already, and we currently don't support
custom plugin features in the registry anyway.
They can be used to select snapping behavior (to previous, next, or
nearest location, where relevant) when seeking.
The seeking implementation (eg, demuxer) may currently ignore some
or all of these flags.
It's only used internally, most other users will likely
want to use gst_registry_find_plugin() directly instead
(and if not, they can easily walk the list and doing the
strcmp themselves).
There's no reason anyone would want to derive from this, so
just make opaque until we manage to make all the private bits
private properly (which I'm not doing right now because it's
more invasive and I have registry modifications locally which
touch all that code as well).
This is an implementation detail really, and it's not
clear what anyone would do with this. It's unused as
far as I'm aware, so just remove it for now.
Rename the _get_value_array() functions to _get_g_value_array() and reintroduce
the former to operate on plain unboxed c datatypes (like in 0.10). The _g_value
variants are for bindings while the _value ones are more suited to processing
in elements.
Reset the buffer not after we acquire but before we release into the pool. This
makes sure that the pool only has buffers in a clean state and that we can set
extra metadata on buffers in the acquire method. this means that we need to
remove an argument from the method.
Add a new LOCKED flag to the metadata. Refuse removing LOCKED metadata from
a buffer.
Mark the metadata from the bufferpool LOCKED.
Add unit test for LOCKED flag
Ass serialize and deserialize functions for GstSegment so that gdp and
gst_structure_to_string show the segment values. We convert to a GstSegment
first to make things easier..
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=674100
Add gst_element_class_{add,set}_metadata() variants for static strings,
so we can avoid unnecessary g_strdup()s.
API: gst_element_class_add_static_metadata()
API: gst_element_class_set_static_metadata()
After a writer has written to its reserved write location, it can only make the
location available for reading if all of the writers with lower locations have
finished.
Fix a race where the reader would see the updated the tail pointer before the
write could write the data into the queue. Fix this by having a separate reader
tail pointer that is only incremented after the writer wrote the data.
Remove GST_MAJORMINOR and replace it by GST_API_VERSION
Also set GST_VERSION_{MAJOR,MINOR,MICRO,NANO} explicitely
now.
All versions are at 1.0.0 now for the release soon but
API/ABI can still change until the 1.0.0 release.
Next release versions until 1.0.0 will be 0.10.9X and
these will be release candidates. GST_VERSION_* will
nonetheless stay at 1.0.0.0.
gst_buffer_take_memory -> gst_buffer_insert_memory because insert is what the
method does.
Make all methods deal with ranges so that we can replace, merge, remove and map
a certain subset of the memory in a buffer. With the new methods we can make
some code nicer and reuse more code. Being able to deal with a subset of the
buffer memory allows us to optimize more cases later (most notably RTP headers
and payload that could be in different memory objects).
Make some more convenient macros that call the more generic range methods.
Add gst_buffer_append() which appends the memory blocks from one buffer to
another. Remove the old inefficient _merge() and _join() methods which forced a
premature memcpy in most cases.
Remove the _is_span() and _span() methods they are not needed anymore now that
we can _append(). Merging and spanning will be delayed until mapping or maybe
not at all when the element can deal with the different memory blocks.
Remove the const from the GstCaps in get/set_param. set_param modifies
the refcount of the caps.
Don't increment the refcount of the caps result of get_param like we
do with other objects.
Update some annotiations.
Improve the docs of the get/pull_range functions, define the lifetime of the
buffer in case of errors and short reads.
Make sure the code does what the docs say.
Make it possible to wrap all kinds of memory by exposing all properties to
gst_buffer_new_wrapped_full(). This makes it possible to also create writable
memory without a free function or memory with extra padding.
Make it so that one can specify a buffer for get/pull_range where the downstream
element should write into. When passing NULL, upstream should allocate a buffer,
like in 0.10.
We also need to change the probes a little because before the pull probe, there
could already be a buffer passed. This then allows us to use the same PROBE
macro for before and after pulling.
While we're at the probes, make the query probe more powerful by handling the
GST_PAD_PROBE_DROP return value. Returning _DROP from a query probe will now
return TRUE upstream and will not forward the probe to the peer or handler.
Also handle _DROP for get/pull_range properly by not dispatching to the
peer/handler or by generating EOS when the probe returns DROP and no buffer.
Make filesrc handle the non-NULL buffer passed in the get_range function and
skip the allocation in that case, writing directly into the downstream provided
buffer.
Update tests because now we need to make sure to not pass a random value in the
buffer pointer to get/pull_range
Separate the bufferpool and allocator hints in the allocation query, some
of the values don't always make sense together.
Keep the bufferpool and its configuration together.
Keep the allocator and its parameters together.
Allow for multiple bufferpool configurations in the query.
Group the extra allocation parameters in a GstAllocationParams structure to make
it easier to deal with them and so that we can extend them later if needed.
Make gst_buffer_new_allocate() take the GstAllocationParams for added
functionality.
Add boxed type for GstAllocationParams.
Change gst_allocator_alloc() so that we can also spicify flags and padding.
Add 2 new flags to mark the memory 0 prefixed/padded. This allows us to
remove some resizes in the base classes.
When allocating memory, memset prefix and padding with 0 when the flags tell
us to.
On resize, clear the zero padding flags if we can't guarantee the memory is
still 0 filled.
Update tests.
Negotiating padding is needed on second thought so include it in the
ALLOCATION query.
Make the bufferpool take padding into account when allocating.
Make basesrc take padding into account.
Use padding and prefix when allocating in basetransform.
Also register queries with a QueryType that allows us to check if the event is
sent in the right direction. Add a serialized query type because we will need
this for the allocation query.
Remove the QueryTypeDefinition stuff, it is not used anymore and we now use
custom queries and separate API for them.
Update defs.
Rename _do_simplify() to _simplify(). The name was introduced as a replacement
method for a deprecated method but we can now rename it again.
Fix some docs.
Make gst_caps_do_simplify() take ownership of the input caps and produce a
simplified output caps. This removes the requirement of having writable input
caps and the method can make the caps writable only when needed.
Rework some caps operations so they don't rely on writable caps but instead take
ownership of the input caps and do _make_writable() only when needed.
Remove some const from caps functions, it does not make much sense for
refcounted objects and does not allow us to return a refcount to the const input
caps.
Rework the base classes fixate vmethods to not operate on the caps in-place.
All this saves us around 30% of caps and structure copy and new operations.
Make a helper function check_sticky to check and push pending sticky events.
Move the handling of the result of pushing the sticky event inside the
push_event function, we need to mark the event as received when it was pushed
correctly.
Move the sticky events code outside of gst_pad_push_event_unchecked and
make it purely handle sending the event to the peer.
when pushing a sticky event, first store it on the pad. Then check and push any
pending sticky events when we get a serialized or sticky event on a srcpad. This
fixes the issue where sticky events are not pushed when an event is pushed.
