This static library gets included directly into libgstreamer-1.0.so, so it needs
the same GST_EXPORTS definition as the rest of the code that's compiled into
that otherwise it will try to find the constants it uses from gstinfo via DLL
importing (__declspec(dllimport)).
Fixes https://ci.gstreamer.net/job/cerbero-cross-mingw32/4393/
__declspec(dllexport/import) are supported by GCC and are needed for
properly generating code that fetches the values of constants from DLLs
built with __declspec(dllexport) which happens when anything using
GST_EXPORT is built with MSVC.
See: https://msdn.microsoft.com/en-us/library/619w14ds.aspx
Essentially, if you built gstreamer with MSVC and then tried to use
constants from it (such as GST_TYPE_CAPS) in a plugin, GCC would
retrieve the address of the value instead of the value itself.
The git-update.sh now builds with all cores available. In case of
failure it defaults to 1
The developer can still override this by setting -j to something else
in MAKEFLAGS, as stated by 299605dfe2.

This means applications and bin sub-classes can easily track when
a new child element is added to the pipeline sub-hierarchy or
removed.
Currently doesn't signal deep added/removed for elements inside
a bin if a bin is added/removed.

Make it explicit that the pad is only blocked while the callback is running,
and the pad will be unblocked again once the callback returned.
If BLOCK and IDLE behaviour is needed, both need to be used.

... when flushing and deactivating pads. Otherwise downstream might have a
query that was already unreffed by upstream, causing crashes or other
interesting effects.

The subclass should do that already, but just in case do it ourselves too as a
fallback. Without this, e.g. playbin will just wait forever if this fails
because it is triggered as part of an ASYNC state change.
When doing a transition from PLAYING to PLAYING, we will fail
to forward an EOS message on the bus, and noone else will ever
send it because there'll be no actual state changed message.
Allow EOS through directly in that case.
If there is only one pad in the internal pads, when folding for
LATENCY queries it will just drop the response if it's not live.
This is maybe not the proper fix, but it will just accept the first
peer responses, and if there are any other pads, it will only take
them into account if the response is live.
This *should* properly handle the aggregation/folding behaviour of
multiple live peer responses, while at the same time handling the
simple one-pad-only-and-forward use-case

A lot of debug categories are declared in element class_init
functions, which don't get run until the element is first created
(not just registered in the plugin load function). This means
that --gst-debug-help doesn't print out a lot of categories.
Creating an instance of each element from the element factory
makes them visible, at some extra cost - 2-3 times longer, which can
be a full second or two of extra waiting. Yikes!

The other signal handlers of the type-found signal might have reactivated
typefind in PULL mode already, pushing a CAPS event at that point would cause
deadlocks and is in general unexpected by elements that are in PULL mode.
https://bugzilla.gnome.org/show_bug.cgi?id=765906
When activating a pad in PULL mode, it might already be in PUSH mode. We now
first try to deactivate it from PUSH mode and then try to activate it in PULL
mode. If the activation fails, we would set the pad to flushing and set it
back to its old mode. However the old mode is wrong, the pad is not in PUSH
mode anymore but in NONE mode.
This fixes e.g. typefind in decodebin reactivating PUSH/PULL mode if upstream
actually fails to go into PULL mode after first PUSHING data to typefind.
POSIX standards requires strsignal() to return a pointer to a char,
not a const pointer to a char. [1] On uClibc, and possibly other
libc's, that do not HAVE_DECL_STRSIGNAL, libcompat.h declares
const char *strsignal (int sig) which causes a type error.

gst_check_setup_sink_pad() internally uses gst_check_chain_func() so we
should call gst_check_drop_buffers() when tearing down tests to free the
buffers which have been exchanged through the pipeline.
https://bugzilla.gnome.org/show_bug.cgi?id=765903
The test rely on bus being flushed when setting the bin to the NULL state which
is not the case. This apply only when setting the pipeline state to
NULL.

Basically, sq->max_size.visible is never increased for sparse streams in
overruncb when empty queue has been found;
If the queue is sparse it just skip the entire logic determining whether
max_size.visible should be increased, deadlocking the demuxer.
What should be done instead is that when determining if limits have been
reached, to ignore time for sparse streams, as the buffer may be far in the
future.

This calls a function from another thread, asynchronously. This is to be
used for cases when a state change has to be performed from a streaming
thread, directly via gst_element_set_state() or indirectly e.g. via SEEK
events.
Calling those functions directly from the streaming thread will cause
deadlocks in many situations, as they might involve waiting for the
streaming thread to shut down from this very streaming thread.
This is mostly a convenience function around a GThreadPool and is for example
used by GstBin to continue asynchronous state changes.

g_signal_emit_by_name() is not like gst_app_src_push_buffer() due to reference
counting limitations of signals, it does *not* take ownership of the buffer.
To allow the GstTestClock to be used as a GstSystemClock, it is
useful to implement the clock-type property that GstSystemClock
provides. This allows GstTestClock to be used as the system clock
with code that expects a GstSystemClock.

Passing years > 9999, months > 12 or days > 31 to gst_date_time_new() will
cause an assertion and generally does not make much sense. Instead consider it
as a parsing error like hours > 24 and return NULL.
Otherwise PTS and DTS will come out of sync if upstream continues to provide
PTS and not DTS, and we have to skip some data from the stream or PTS are not
exactly increasing with the duration of each packet.
