Makes gst_bus_add_watch(), gst_bus_add_watch_full(), gst_bus_add_signal_watch(),
and gst_bus_add_signal_watch_full() convenience functions automatically pick up
any non-default main contexts set for the current thread via
g_main_thread_push_thread_default().

The description string was changed to an inlined string a while back.
(But: no need to intern the const strings here, we just use the interning
to avoid allocating duplicates and make memory management easier,
since the strings will be around for the life-time of the app anyway).

Only replace existing plugins by blacklisted ones if they correspond
to the exact same plugin. If they're not the same, keep the existing
valid one.
Fixes#638941
Ignore plugins which have been moved into coreelements, so it's
still possible to just upgrade GStreamer core without having to
upgrade the whole stack.
This reverts commit f9039c2204.
We use -DG_DISABLE_ASSERTS for releases and pre-releases, but
don't want to disable pad name checking for releases in general,
I think. Need a better solution here. Fixes pad unit test in
pre-release/release mode.
Avoid unnecessary malloc/free to get the file basename on MSVC to avoid
unnecessary overhead when doing GST_DEBUG=foo:5 or so (since it would be
done before the category log level filtering).
The new request_new_pad_full vmethod provides an additional caps field,
which allows elements to take better decision process.
Also, add a gst_element_request_pad() function to allow developers to be
able to specify which pad template they want a pad of.
Convert gstutils to use that new method instead of the old one when more
efficient.
This is useful for being able to request pads in a more flexible way,
especially when the element can provide pads whose caps depend on
runtime configuration and therefore can't provide pre-registered
pad templates.

We need to reset the revents field of each pollfd when reading the results
from select else we'll end up with stray info from previous calls to
select.
Fix freeing of partially-inited list value when both values
passed are equal and we want to return a single non-list
value as result. Fixes unit test. Also fix up docs a bit.

The -Bsymbolic change causes us to get a different address when internaly
looking up the function than what application would get when the use the symbol
that they see. This made removing the default loghandler to fail, as it is set
internally and removed externaly.
Make the _get_caps functions behave like the _get_caps_reffed variants and
remove the _reffed variants. This means that _get_caps doesn't return a writable
caps anymore and an explicit _make_writable() is needed before modifying the
caps.
Make GstObject extend from GInitiallyUnowned, remove the FLOATING flag and use
GObject methods for managing the floating ref.
Remove class lock, it was a workaround for a glib < 2.8 bug.
Remove the parent-set and parent-unset signals, attempt to implement with notify
but disabled because deadlocks in deep-notify.
All functions in this file can access the structure field of a query directly.
This avoids having to call gst_query_get_structure() to get it, along with being
able to remove some function variables that were used to store the result of that
function.
All functions in this file can access the structure field of an event directly.
This avoids having to call gst_query_get_structure() to get it, along with being

There is no need to cache the peer chainfunction as we can just as efficiently
get to it from the peer object. Also not caching the chain function works better
because then we automatically get the new chainfunctions when they change.
Build the cache while we push data. When we don't have a cache, we run the
slowpath and collect cacheable properties. When all conditions are met, keep the
cached data around so that we can more efficiently push data around.
Fix returning of timezones on systems with gdatetime
to use floats on the math expression to avoid
truncating the fractional part.
Also adds a test for covering this case.
Otherwise the source will stay at NULL, the event is passed to the
peerpad via gst_pad_send_event() and then the peerpad is set as
source of the event instead of the originating pad.
This change always defines the restrict keyword if a
non-C99 C compiler is used. In the case of GCC >= 4
it will be defined to __restrict__, in all other
cases to nothing. This allows to use the restrict
keyword unconditionally.
Adds 2 variants for the gst_date_time_from_unix_epoch function,
one for UTC and another for local time.

Basically we're not meant to put anything more complex than simple numbers,
due to the definition of G_GUINT64_CONSTANT:
G_GUINT64_CONSTANT(val) (val##UL)
Which previously resulted in .... 1 << 49UL
gst_mini_object_unref() has guards that check the type already, so
we don't really need to re-check it here again while getting the
class (there's not really much point to that anyway, since we don't
check the return value of the get_class, so we'd crash anyway if
we're not dealing with a mini object, the only question would
be if there'd be a warning before the crash or not).
Track elements tagged with the IS_SOURCE flag in a similar way we track the sink
elements. This allows us to efficiently dispatch downstream events to the right
elements.
Add minimal math-compath.h header where we can define fallback
versions for miscellaneous math functions that aren't always
available, so we don't have to duplicate this in plugins.
The header is not included by default, so needs to be
included explicitly for now.

Adds a new tag to indicate the error in horizontal positioning
in meters. This is one of the available 'gps error' fields in
exif, for example.
API: GST_TAG_GEO_LOCATION_HORIZONTAL_ERROR
Add gst_is_initialized() guard to gst_element_factory_make(), so
people who forgot to call gst_init() get a useful warning for what
seems to be a common enough mistake.
Sprinkle some G_UNLIKELY(), return TRUE/FALSE constants, avoid an
unnecessary g_value_unset(), move g_value_init()+set_int64_range()
closer to where they're needed.
Don't create a new GValueArray copy for every single _add_buffering_range()
call, but append to the existing value array owned by the structure instead.
Add _set_value() variants that take ownership of the value passed
instead of making a copy of the value. This is useful for setting
values to things that aren't refcounted (e.g. GValueArrays or
strings or string arrays, etc.).

Add an option to forward all the internal messages that would otherwise be
filtered such as EOS, SEGMENT and ASYNC messages.
This allows the application to, for example, detect that a partial pipeline is
prerolled or reached eos.
The original messages are wrapped inside an element message because the parent
bins are not supposed to see those internal messages escape.
A flush-stop event would make a pad unflushing, causing it
to start acting as an activated pad. This, for example,
could lead to the chain function being called when stuff
isn't initialized.
This could happend when setting qtdemux to NULL while a seek
was being handled in the upstream filesrc (in push mode).
This patch makes it check if it is activated before setting
it to unflushing.
