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.
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.

Don't export those 35-something random _gst_parse_yy* symbols. These were
never in any header files and also blacklisted from our .def files, in
case anyone wonders.
Fix 'grammar.tab.c:815:6: warning: "YYENABLE_NLS" is not defined'
compiler warning and the same for YYLTYPE_IS_TRIVIAL. The two
translated strings aren't particularly helpful, so just define
YYENABLE_NLS to 0.
Right now deleyed set would only try for first set of children. We need to keep
trying to support arbitrary deep hierarchies (like in playbin2 with auto*sinks).
Also GstBin would need to actualy emit the child-added/removed signal as it
implements the iface. Fixes#613215.
Adds that warning to configure.ac
Includes a tiny change of the GST_BOILERPLATE_FULL() macro:
The get_type() function is no longer declared before being defined.
https://bugzilla.gnome.org/show_bug.cgi?id=611692
For the reason outlined at the beginning of gst_private.h (inline
functions in glib may need the g_log_domain variable). Also include
gst_private.h before using any G_OS_* defines, esp. in plugin loader.
If deserializing a property fails, check if the value type is a string and if so
attempt to create a bin from the string value. This allows to e.g. specify
audio-sink/video-sink for playbin on gst-launch commandline.

Get all missing elements from a parse launch string if possible
(ie. if the FATAL_ERRORS flag has been specified). Fixes#528178.

* gst/parse/Makefile.am:
* gst/parse/grammar.y:
* gst/parse/parse.l:
Make the parser reentrant and recursively callable. This requires flex
>= 2.5.31, for older versions pregenerated sources are used as we
can't bump the build dependency. Finally fixes#349180.
* gst/gstparse.c: (gst_parse_launch):
Drop the HAVE_MT_SAVE_FLEX #ifdefs as we always use a new enough flex
now anyway.

If the installed flex version is too old use pre-generated parser
sources. These pre-generated parser sources are always updated when
the actual flex/bison sources change but require everybody who wants
to change something in the parser to have flex >= 2.5.31 installed.
Original commit message from CVS:
* gst/gstelement.c: (gst_element_get_state_func):
Don't output the same debug statement twice.
* libs/gst/base/gstadapter.c: (gst_adapter_try_to_merge_up),
(gst_adapter_peek), (gst_adapter_take_buffer):
Optimise the case where we have buffers at the head of the queue that
can be joined quickly (because they're contiguous sub-buffers) by
merging them together rather than copying data out into new memory.
* gst/parse/grammar.y:
* tests/check/pipelines/parse-launch.c:
Fix a leak in an error path for parse_launch, and add a check
for it to the testsuite.
Original commit message from CVS:
* gst/gst.c: (ensure_current_registry_forking):
Ignore EINTR when reading from the child registry pipe.
Explicitly ignore the return value from close, since it makes no
difference.
* gst/gstminiobject.c: (gst_mini_object_ref),
(gst_mini_object_unref):
When debugging refcounts, check GST_IS_MINI_OBJECT and warn.
* gst/gstregistry.c: (_priv_gst_registry_remove_cache_plugins):
When removing cached plugins, remove their features too, so they're
not visible after they've disappeared.
* gst/gstutils.c: (prepare_link_maybe_ghosting):
In the unlikely case that we are linking pads with no parents, don't
crash trying to get the non-existent parent bin.
* gst/parse/grammar.y:
Output debug in the PIPELINE category
Original commit message from CVS:

* gst/parse/grammar.y:
Remove static function gst_parse_element_lock as all it does
is return. Looks like cruft from 0.8.
Original commit message from CVS:
* gst/gstelementfactory.c: (gst_element_factory_create):
Remove unnecessary ref/unref pair
* gst/parse/grammar.y:
Make sure to free the parse buffer on all code paths.
Move a g_free up to the error handler where it's easier to see.
* tests/check/gst/gstevent.c: (test_event):
Extending timeout for downstream travelling events to 10 seconds to
hopefully avoid intermittent failure on the buildbots.
* tests/check/pipelines/parse-launch.c: (run_delayed_test):
Don't manually set the state of the src element - it will happen as a
natural consequence of the pipeline changing state, and that way it
will do it in the right order too.
Original commit message from CVS:
* gst/parse/Makefile.am:
* gst/parse/grammar.y:
* gst/parse/parse.l:
Reverted previous patch as it required to bump the flex dependency to
2.5.31, where fc4/5 seem to ship only the ancient 2.5.4a :(
