After release bison 2.5 the declaration %pure-parser was deprecated
in favor of %define api.pure
Nonetheless, until bison 3.4, the declaration was treated as backward
compatibility, but now bison shows a warning:
warning: deprecated directive, use ‘%define api.pure’
The patch's approach is to handle both directives according with the
used bison's version, by string replacement at source configuration
stage.
There was a dead assignment used outside of the bin/pipeline creation
which was confusing (and unused). Just move that variable to
where it is actually used.
(Note that that variable was not needed outside of that block since
the refactoring done in 2b33d33185 )
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.

g_object_ref() forwards the type of its argument nowadays.
./grammar.y:409:14: error: assignment from incompatible pointer type [-Werror=incompatible-pointer-types]
gstchildproxy.c:212:7: error: assignment from incompatible pointer type [-Werror=incompatible-pointer-types]
This can easily deadlock if the element uses the object lock for
something internally, like posting an error message. Use an GstIterator
for iterating over the pads instead.

Introduce a new operator ':' - e.g. element1 ':' element2
For example, 'uridecodebin : encodebin' -
if the encodebin has multiple profiles compatible with the
decodebin, multiple links will be created.
With '!' , after one delayed link is successfully done, the
pad-added callback is disconnected.

Fixes xgettext warnings when doing 'make update-po':
gst/parse/grammar.y:217: warning: Empty msgid. It is reserved by GNU gettext:
gettext("") returns the header entry with
meta information, not the empty string.

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded
... and many more. For more details see:

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.
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)).

By default, gst_parse_launch_full() creates a GstPipeline if there's more
than one toplevel element. Add a flag to let it use a GstBin instead.
Also fix the parser to let it use this flag for GST_TYPE_ELEMENT property
values, to avoid having GstPipelines inside other GstPipelines.

The parse-launch API automagically handles dynamic pads and performs delayed
linking as needed, without any feedback about whether the linking succeeded or
not however. If a delayed dynamic link can't be completed for whatever reason,
parse-launch will simply wait in case a suitable pad appears later. This may
never happen though, in which case the pipeline may just hang forever.
Try to improve this by connecting to the "no-more-pads" signal of any element
with dynamic pads and posting a warning message for the related outstanding
dynamic links when "no-more-pads" is emitted.
Fixes#760003
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.
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 makes gst_parse_bin_from_description() return an element instead of
a bin if there's only one element. Also changed gstparse.c to use this,
so gst-launch won't create superfluous bins.
