a2832689ad gstelementfactory: Remove MEDIA_HARDWARE FactoryType
Using the MEDIA_ classifier prefix was inappropriate. It is sufficient to
specify the additional klass name that element can set in their metadata.

ca4b61c555 gstelementfactory: Add MEDIA_HARDWARE klass classifier
The Harware factory type classifier allows elements (decoders and encoders,
mostly) to advertize they rely on hardware devices to perform encoding or
decoding operations. This classifier can be used by applications to filter and
select only the elements that use hardware devices, for instance to ensure
zero-copy support is enabled for a specific pipeline.

05a3da347b protection: Add a new definition for unspecified system protection
In some cases the system protection ID is not present in the contents
or in their metadata.
This define is used to set the value of the "system_id" field in GstProtectionEvent,
with this value, the application will use an external information to choose which
protection system to use.

Example: The matroskademux uses this value in the case of encrypted WebM,
the application will choose the appropriate protection system based on the information
received through EME API.

2fee579747 element: remove inactive pad g_warning in add_pad
The documentation incorrectly used to state that the pads were
not automatically activated when added, whereas we actually do
that when appropriate.

Callers of gst_element_add_pad must not hold the object lock,
which implies that they cannot perform the same checks as
add_pad in a non-racy manner.

This updates the documentation, and removes the g_warning
that was output before performing automatic activation.

57c8e0146f libs: figure out right export define in configure
Add new GST_API_EXPORT in config.h and use that for GST_*_API
decorators instead of GST_EXPORT.

The right export define depends on the toolchain and whether
we're using -fvisibility=hidden or not, so it's better to set it
to the right thing directly than hard-coding a compiler whitelist
in the public header.

We put the export define into config.h instead of passing it via the
command line to the compiler because it might contain spaces and brackets
and in the autotools scenario we'd have to pass that through multiple
layers of plumbing and Makefile/shell escaping and we're just not going
to be *that* lucky.

The export define is only used if we're compiling our lib, not by external
users of the lib headers, so it's not a problem to put it into config.h

Also, this means all .c files of libs need to include config.h
to get the export marker defined, so fix up a few that didn't
include config.h.

This commit depends on a common submodule commit that makes gst-glib-gen.mak
add an #include "config.h" to generated enum/marshal .c files for the
autotools build.

46ed0f0489 libs: fix 'inconsistent DLL linkage' warnings on Windows
For each lib we build export its own API in headers when we're
building it, otherwise import the API from the headers.

This fixes linker warnings on Windows when building with MSVC.

The problem was that we had defined all GST_*_API decorators
unconditionally to GST_EXPORT. This was intentional and only
supposed to be temporary, but caused linker warnings because
we tell the linker that we want to export all symbols even
those from externall DLLs, and when the linker notices that
they were in external DLLS and not present locally it warns.

What we need to do when building each library is: export
the library's own symbols and import all other symbols. To
this end we define e.g. BUILDING_GST_FOO and then we define
the GST_FOO_API decorator either to export or to import
symbols depending on whether BUILDING_GST_FOO is set or not.
That way external users of each library API automatically
get the import.

50038bed79 gstconfig.h: add GST_API_IMPORT define
This is for use by the various GST_*_API decorators and
will be what they get defined to when a library API is being
used by external users of that library (not the library itself
whilst it's being compiled).

In most cases it will simply map to a plain 'extern' but on
Windows with MSVC it will need to map to __declspec(dllimport).
For functions this is not strictly needed, but for exported
variables it is.

f5783e1cac pad: Accumulate live/non-live latency values separately
And only ever use the non-live values if all pads are non-live,
otherwise only use the results of all live pads.

It's unclear what one would use the values for in the non-live case, but
by this we at least pass them through correctly then.

This is a follow-up for 794944f779, which
causes wrong latency calculations if the first pad is non-live but a
later pad is actually live. In that case the live values would be
accumulated together with the values of the non-live first pad,
generally causing wrong min/max latencies to be calculated.

c3d3cf074e pad: Ensure that the pad is blocked for IDLE probes if they are called from the streaming thread too
IDLE probes that are directly called when being added will increase /
decrease the "number of IDLE probes running" counter around the call,
but when running from the streaming thread this won't happen.

This has the effect that when running from a streaming thread it is
possible to push serialized events or data out of the pad without
problems, but otherwise it would deadlock because serialized data would
wait for the IDLE probe to finish first (it is blocking after all!).

With this change it will now always consistently deadlock instead of
just every once in a while, which should make it obvious why this
happens and prevent racy deadlocks in application code.

2aa9ad9c62 Revert "pad: Handle changing sticky events in pad probes"
This reverts commit 11e0f451eb.

When pushing a sticky event out of a pad with a pad probe or pad offset,
those should not be applied to the event that is actually stored in the
event but only in the event sent downstream. The pad probe and pad
offsets are conceptually *after* the pad, added by external code and
should not affect any internal state of pads/elements.

Also storing the modified event has the side-effect that a re-sent event
would arrive with any previous modifications done by the same pad probe
again inside that pad probe, and it would have to check if its
modifications are already applied or not.

For sink pads and generally for events arriving in a pad, some further
changes are still needed and those are tracked in
  https://bugzilla.gnome.org/show_bug.cgi?id=765049

In addition, the commit also had a refcounting problem with events,
causing already destroyed events to be stored inside pads.

6fa351407a miniobject: Add parent pointers to the miniobject to influence writability
Every container of miniobjects now needs to store itself as parent in
the child object, and remove itself again at a later time.

A miniobject is only writable if there is at most one parent, and that
parent is writable itself, and if the reference count of the miniobject
is 1.

GstBuffer (for memories), GstBufferList (for buffers) and GstSample (for
caps, buffer, bufferlist) was updated accordingly.

Without this it was possible to have e.g. a bufferlist with refcount 2
in two places, modifying the same buffer with refcount 1 at the same
time.

ae612551fa gstdebug: fix occasional deadlocks on windows when outputting debug logging
When outputting debug logs on Windows, some sections are protected
with a non-recursive lock. Turns out though that gst_debug_message_get()
might indirectly, via our printf format extensions, call code which
in turn would try to log something when it can't handle something. If
that happens we end up in gst_debug_log_default() again recursively and
try to again take the lock that's already taken, thus deadlocking.

Format the debug message string outside of the critical section
instead to avoid this.

31383e4413 gstpad: Avoid stream-dead-lock on deactivation
The following case can happen when two thread try to activate and
deactivate a pad at the same time:
T1: starts to deactivate, calls pre_activate(), sets in_activation
    to TRUE and carries on
T2: starts to activate, calls pre_activate(), in_activation is TRUE
    so it waits on the GCond
T1: calls post_activate(), tries to acquire the streaming lock ..
    but can't because T2 is currently holding it

With this patch, the deadlock will no longer happen but does not
solve the problem that:
T2: will resume activation of the pad, set the pad mode to the target
   one (PUSH or PULL) and eventually the streaming lock gets released.
T1: is able to finish calling post_activate() ... but ... the pad
   wasn't deactivated (T2 was the last one to "activate" the pad.

When registering a new debug category after gst_init(), simply check

No need to iterate over all categories and recheck them all against
the existing patterns.

Also, no need to re-parse the existing pattern string set via GST_DEBUG
and add the same set of match patterns all over again to the existing
list of match patterns every time we register a new debug category.

Combined with iterating all debug categories on a change this would
make adding debug categories after gst_init() very very very slow.

512cec3dea pad: gst_pad_activate_mode() always succeed if same mode
Checking that the pad is in the correct mode before the parent is
checked makes the call always succeed if the mode is ok.

This fixes a race with ghostpad where gst_pad_activate_mode() could
trigger a g_critical() if the ghostpad is unparented while the
proxypad is deactivating, for instance if the ghostpad is released.
More specifically, gst_ghost_pad_internal_activate_push_default()'s
call to gst_pad_activate_mode() would fail if ghostpad doesn't have a
parent. With this patch it will return true of mode is already
correct.

d915dd4b20 gstpad: Make pad (de)activation atomic
The following could happen previously:
* T1: calls gst_pad_set_active()
* T2: currently (de)activating it
* T1: gst_pad_set_active() returns, caller assumes that the pad has
  completed the requested (de)activation ... whereas it is not
  the case since the actual (de)activation in T2 might still be
  going on.

To ensure atomicity of pad (de)activation, we use a internal
variable (and cond) to ensure only one thread at a time goes through
the actual (de)activation block

Add convenience API that iterates over all pads, sink pads or

or removed while the function is executing. We can still do that
in future if we think it's needed, but in practice it will
likely make absolutely no difference whatsoever, since these
things will have to be handled properly elsewhere by the element
anyway if they're important.

After all, it's always possible that a pad is added or removed
just after the iterator finishes iterating, but before the
function returns.

This is also a replacement for gst_aggregator_iterate_sink_pads().

ebad8c0094 bin: iterate_sorted: Ensure sources are always returned last
For linked elements, the resulting gst_bin_iterate_sorted() will
properly return elements from sink to sources.

If we have some elements that are not linked, we *still* want to
ensure that we return:
* In priority any sinks
* Last of all any sources
* And in between any element which is neither source nor sink

For this to work, when looking for the next candidate element,
not only check the degree order, but if there are two candidates
with the same degree order, prefer the non-source one.

Amongst other things, this fixes the case where we activating a
bin containing unlinked sources and other elements. Without this
we could end up activating sources (which might start adding pads
to be linked) before other (to which those new source element pads
might be linked) are not activated

6cddce7663 plugin: API: GST_PLUGIN_DEPENDENCY_FLAG_PATHS_ARE_RELATIVE_TO_EXE
When a plugin declares a dependency using this flag, all the
relative paths are considered to be relative to the path of
the main executable.

We try to determine the path of the executable portably,
with implementations provided for Linux, Windows and Mac.

If retrieval of the path fails, we will not detect changes.

In order for the main executable path to be the same when
scanning a plugin in a child process, a new variable is
exposed in gst_private.h, _gst_executable_path
