087aa6ced4 gst_private.h: make sure gst_private.h is included before glib.h
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.

e2c1a6f7e9 gst/parse/parse.l: Use "%option never-interactive" to prevent useless calls to isatty() on every input when parsing. ...
Original commit message from CVS:
* gst/parse/parse.l:
Use "%option never-interactive" to prevent useless calls to isatty()
on every input when parsing. Also use "%option noinput" to not define
the static input/yyinput functions which we don't use anyway. This
removes a compiler warning with gcc 4.3 and saves some bytes in the
library.
* gst/parse/lex._gst_parse_yy.pre.c:
Regenerated for the above change.

* 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/parse/parse.l:
Commit patch for parse_launch syntax from #331255. Removes
support for quoted strings and mimetypes when writing filtered
caps. See the bug report for more details - I'm pretty sure this
obscure feature is not in use by _anyone_ anywhere.

With this simple change, the size of the gstreamer.so here
drops from 2193KB to 1565KB.

cded585aa2 gst/: Debugging tweaks.

* gst/gstbin.c:
* gst/gstbuffer.c:
* gst/gstplugin.c:
* gst/registries/gstxmlregistry.c:
* gst/schedulers/gstoptimalscheduler.c: Debugging tweaks.

* gst/gstelement.c (gst_element_set_scheduler): Debugging fixes.
(gst_element_add_pad): DEBUG->INFO, some fixes.
(gst_element_get_compatible_pad_template): Just see if the
templates' caps intersect, not if one is a strict subset of the
other. This conforms more to what gst_pad_link_intersect() does.
(gst_element_class_add_pad_template): Don't memcpy the pad
template, just ref it.
(gst_element_get_compatible_pad_filtered): Clean up debug messages

* gst/gstpad.c (gst_pad_can_link_filtered): Debug a true result.
(gst_pad_link_filtered): Debug changes.
(gst_pad_link_prepare): New function, consolidated from
can_link_filtered and link_filtered.

* gst/parse/grammar.y (gst_parse_perform_link): Made INFO output
look more like that of the functions in gstelement.c

* gst/gstinfo.c (gst_debug_print_object): Put a space before the
object, and return the empty string if object is NULL.

* gst/parse/parse.l: Remove trailing newlines when calling PRINT.
* gst/parse/grammar.y (YYFPRINTF): Log bison debugging info via
LOG, not DEBUG. We still get flex info on debug.

* gst/registries/gstxmlregistry.c (gst_xml_registry_load): Make
debug string more verbose.
(plugin_times_older_than): DEBUG->LOG.

25f85868d4 implement URI schemes
Original commit message from CVS:
implement URI schemes
Elements can now register as a source or sink for a protocol and applications can use gst_element_make_from_uri () to get an element that handles a given URI.
This patch provides:
- removal of old broken URI handling scheme.
- new URI handling using interfaces.
- updates for registry to save handled URIs.
- interface for URI handlers.
- implementation of that in filesrc and filesink for the file:// URI
- extension to pipeline parsing to allow specifying only a URI instead of element

Does not include:
- tests
- inclusion in docs build

Original commit message from CVS:
GST_DEBUG reorganization
This is a big diff (ca 450k), containing loads of stuff:
- gstinfo.[ch] complete rewrite
- changing of all GST_DEBUG messages to reflect that change
- reorganization of subsystem disabling
- addition of gstconfig.h.in so we can track the disablings
- <gst/gst.h> does not include <unistd.h> and <config.h> anymore
- documentation updated for gstinfo stuff (build the docs yourself to know what changed)
- bugfixes for making of the docs (files from CVS are not deleted anymore
- testsuite for debugging changes in testsuite/debug

3a897e2f30 rewritten pipeline parsing lands. Have fun breaking it.
Original commit message from CVS:
rewritten pipeline parsing lands. Have fun breaking it.
regressions:
- No support for filtered links. If anybody needs this, please contact me and I'll add it as fast as possible.

improvements:
- The pipeline building actually works as expected.
- syntax compatible nearly everywhere but more flexible
- better property parsing (you can now set enums by name or nick)
- uses locked_state to allow for delayed pads
- can connect video pipelines without the need for queues
- allows properties on bins
- does not return a bin, but an element.

You may want to read docs/random/company/gstparse to learn how it works.
