7c4d3a6c52 gst: Fix floating reference inconsistencies in error cases
If a function takes a floating reference and sinks it, it should also do
that in error cases. I.e. call ref_sink() followed by unref().

Otherwise the reference counting behaviour of the function will be
different between the good and the error case, and simply inconsistent.

0eecc49c13 gst: add GST_DEPRECATED_FOR() and also export deprecated symbols
Can't use a #ifndef GST_DISABLE_DEPRECATED guard around deprecated
functions any more, as they won't get exported then. Besides, we
get a nicer error message from the compiler telling us what function
to use instead this way.

7d930b8693 buffer: Add GstReferenceTimestampMeta
This is a meta that generically allows to attach additional reference
timestamps to a buffer, that don't have to relate to the pipeline clock
in any way.

Examples of this could be an NTP timestamp when the media was captured,
a frame counter on the capture side or the (local) UNIX timestamp when
the media was captured.

e7ede5a487 plugin: Unify static and dynamic plugin interface
This patch changes the entry point of each plugin in order to unify the
interface for static and dynamic plugin. What we do is replace the
current static plugin interface and extend the dymamic one. The plugin
entry was a C structure, name "gst_plugin_desc". With this patch, the
interface is now:

  GstPpluginDesc *gst_plugin_<name>_get_desc(void);

The reason we change the C structure into function, is that it is
potentially more common to have function pointers, avoiding possible
binding language limitation. Additionally to that. This change prevents
the symbols from clashing between plugins, allowing to build once the
plugin (assuming you have -fPIC).

On the plugin loader side, we symply derive the shared object basename
to extract the plugin name. If this symbol is not found, we fallback to
gst_plugin_desc for backward compatibility.

This has one side effect, which is that the shared objects now need to
be named after their plugin name. This is generally the case with few
exceptions. The benifit of this limitation is that you can control the
gst_plugin_<name>_desc clash at file level.

d108ed2251 gst: check non-null before dereference
It is possible to use gst_deinit() without registering the base
classes. For example, when using gst_init_get_option_group() and
call the program with an invalid parameter. In that case,
gst_deinit() will lead to a segmentation fault, since there is a
dereference to a pointer that is null.

This patch validates if the type is non-null before dereferencing
it.

519d64881f Don't use deprecated g_object_newv()
Use g_object_new() instead which nowadays has a shortcut for the
no-properties check. It still does an extra GType check in the
function guard, but there's a pending patch to remove that
and it's hardly going to be a performance issue in practice,
even less so on a system that's compiled without run-time checks.

Alternative would be to move to the new g_object_new_properties()
with a fallback define for older glib versions, but it makes the
code look more unwieldy and doesn't seem worth it.

Fixes deprecation warnings when building against newer GLib versions.

c173771ed2 gst: Use GstClockTimeDiff instead of GstClockTime as type for GST_SECOND and friends
They were (signed!) gint64 before because of G_GINT64_CONSTANT() already
and they are actually used in signed calculations.

With this change we at least ensure that an integer type of the correct
size is used for GI (it was using gint before).

efbacf1931 streamcollection: fix racy user-after-free
The issue happens when the structure is printed by the logging
subsystem: the object is included in the log, and this will cause the
full object printout to be done there. However, after dispose, the queue
was already cleared, so the access to it (to print the object) would
assert, as the queue was already freed. The patch changes it so that the
queue is merely empty, and only freed in _finalize.

3b9ff1245b array/fraction: In param types, use get_type() function directly
The GST_TYPE macro points to global variables initialized by the
first call to get_type. This is not an issue if you call gst_init()
but unfortunatly pygi will need to acces the param type before
init can be called. This removes an assertion.

0ff74f8d6d paramspecs: Use gst_value_array_get_type() for GstParamSpecArray type
When registering GstParamSpecArray, use the gst_value_array_get_type()
function to get the type, rather than the GST_TYPE_ARRAY macro, which
gets it from the _gst_value_array_type, which is in turn only
initialised during gst_init()

a3cfcbfede value: Always add the type name to elements when serializing arrays/lists
But only when serializing outside of GstStructures, because in case of
GstStructure the type is already preprended to the array/list and the
GstStructure API makes sure that they have the same "generic" type so
deserialization works properly.

This keeps serialization of GstStructures the same as before, and the
GstCaps unit tests already test for that. However when serializing
standalone arrays/lists get the types added now.
