only scan the GST_PLUGIN_PATH locations, and not add
system locations

2005-06-08 Andy Wingo <wingo@pobox.com>
* gst/gstutils.c: RPAD fixes all around.
(gst_element_link_pads): Refcounting fixes.
* tools/gst-inspect.c:
* tools/gst-xmlinspect.c:
* parse/grammar.y:
* gst/base/gsttypefindhelper.c:
* gst/base/gstbasesink.c:
* gst/gstqueue.c: RPAD fixes.
* gst/gstghostpad.h:
* gst/gstghostpad.c: New ghost pad implementation as full proxy
pads. The tricky thing is they provide both source and sink
interfaces, since they proxy the internal pad for the external
pad, and vice versa. Implement with lower-level ProxyPad objects,
with the interior proxy pad as a child of the exterior ghost pad.
Should write a doc on this.
* gst/gstpad.h: s/RPAD/PAD/, s/RealPad/Pad/.
(gst_pad_set_name, gst_pad_set_parent): Macros removed, use
gst_object API.
* gst/gstpad.c: Big changes. No more stub base GstPad, now all
pads are real pads. No ghost pads in this file. Not documenting
the myriad s/RPAD/PAD/ and REALIZE fixes.
(gst_pad_class_init): Add properties for "direction" and
"template". Both are construct-only, so they can't change during
the life of the pad. Fixes properly deriving from GstPad.
(gst_pad_custom_new, gst_pad_custom_new_from_template): Gone. For
derived objects, just set properties when creating the objects via
g_object_new.
(gst_pad_get_parent): Implement as a function, return NULL if the
parent is not an element.
(gst_pad_get_real_parent, gst_pad_add_ghost_pad)
(gst_pad_remove_ghost_pad, gst_pad_realize): Removed.
* gst/gstobject.c (gst_object_class_init): Make name a construct
property. Don't set it in the object init.
* gst/gstelement.c (gst_element_add_pad): Don't allow adding pads
with UNKNOWN direction.
(gst_element_add_ghost_pad): Remove non-orthogonal API. Replace
with gst_element_add_pad (e, gst_ghost_pad_new (name, pad)).
(gst_element_remove_pad): Remove ghost-pad special cases.
(gst_element_pads_activate): Remove rpad cruft.
* gst/gstbin.c (gst_bin_change_state): Use gst_pad_get_parent to
catch the pad's-parent-not-an-element case.
* gst/gst.h: Include gstghostpad.h.
* gst/gst.c (init_post): No more real, ghost pads.
* gst/Makefile.am: Add gstghostpad.[ch].
* check/Makefile.am:
* check/gst/gstbin.c:
* check/gst/gstghostpad.c (test_ghost_pads): Check that linking
into a bin creates ghost pads, and that the refcounts are right.
Partly moved from gstbin.c.
Original commit message from CVS:
* gst/gst.c:
* gst/gstmessage.c:
Make sure the class is reffed/unreffed once before threads can be
used. Fixes#304551.
Original commit message from CVS:
2005-05-06 Andy Wingo <wingo@pobox.com>
* gst/gstquery.h
* gst/gstquery.c (_gst_query_initialize): Extend GstQuery from
GstData, init a memchunk.
(standard_definitions): Add a few query types, deprecate a few.
(gst_query_get_type): New proc.
(_gst_query_copy, _gst_query_free, gst_query_new): GstData
implementation.
(gst_query_new_application, gst_query_get_structure): New public
procs.
* docs/design/draft-query.txt: Removed LINKS from the query types,
because all the rest can be dispatched to other pads -- seemed
ugly to have a query that couldn't be dispatched. internal_links
is fine as a pad method.
* gst/gstpad.h: Add query2 as a pad method, add the new functions
in gstpad.c, but maintain binary compatibility for the moment.
Will fix before 0.9 is out.
* gst/gstqueryutils.c:
* gst/gstqueryutils.h: New files, implement 3 methods for each
query type: parse_query, parse_response, and set. Probably need an
allocator as well.
* gst/gst.h: Add gstquery.h and gstqueryutils.h to the list.
* gst/elements/gstfilesink.c (gst_filesink_query2):
* gst/base/gstbasesrc.c (gst_basesrc_query2): Replace old query,
query_types, and formats methods.
* gst/gstpad.c (gst_pad_query2, gst_pad_query2_default)
(gst_pad_set_query2_function): New functions.
(gst_real_pad_init): Set query2_default as the default query2
function. Basically just dispatches to internally linked pads.
Needs review!
* gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1
without using the atomic operations. Only one thread can possibly
be accessing the data at this point. Changed so as to avoid
gst_atomic operations.
Original commit message from CVS:
* gst/Makefile.am: remove gstcpu.[ch]. The gst_cpu functionality
is broken and should be implemented in a different library.
* gst/gst.c: (init_post): don't call _gst_cpu_initialize()
* gst/gst.h: remove gstcpu.h
* gst/gstcpu.c: remove
* gst/gstcpu.h: remove
* gst/Makefile.am.future: Remove this file. It's ancient.

(gst_init_check_with_popt_table): Fix some gettext strings to
make them easier to translate. Required making the strings
non-const.

Original commit message from CVS:
merge in tagging
Includes:
- gsttag.[ch] - The definition of GstTagList and tag registering/querying
- gsttaginterface.[ch] - Interface for elements that can handle setting of tags
- updates and merges to gststructure.[ch] and gstvalue.[ch]
- testsuite/tags - some tests for tagging
- bugfixes
- updates to make make distcheck work
- updates the version number to 0.7.2.1
Does not include:
- including tagging stuff in docs
- extensive tests
Original commit message from CVS:
improve debugging options:
- don't compile in debug help if compiled with GST_DISABLE_GST_DEBUG
- load all plugins on gst_debug_help so that all debugging categories can be displayed
Original commit message from CVS:
merge TYPEFIND branch. Major changes:
- totally reworked type(find) system
- bytestream is out of the core again
- typefind element is now part of gstelements
Original commit message from CVS:
fix threading on non-optimized atomic architectures. This unfortunately requires initializing threading in init_pre because the debugging subsystem needs this. Therefore the --gst-nothreads command line option does not work anymore. So I erased it. You can however still call gst_use_threads (FALSE); before calling gst_init
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
expect breakage
Original commit message from CVS:
many changes to startup handling:
- make gst_init_with_popt_table work like gst_init - exit program on failure, return void
- add gst_init_check_with_popt_table to be the same as gst_init_with_popt_table before - work the same as gst_init_check
- revert an old workaround and apply the proper fix
- do not use g_error to exit the application, g_error causes a segfault. Use exit.
Original commit message from CVS:
- Add more --disable options
- fix makefiles to only compile non-disabled features
- some compile fixes.
- removed extratypes, added gsturitype
- make get/set clock on a bin overridable
- some portability fixes for GUINT64
- separate pools from gstregistry.[ch] into gstregistrypool.[ch]
- make gstobject size fixed, even if we disabled load/save
- don't use 'new' as a variable as it is not a valib C++ variable
Original commit message from CVS:
- Added PAD_NEGOTIATING flag, remove PAD_EOS flag
- Try to avoid negotiation in state change if pad were already negotiating
- Added gstquery.c for completeness (maybe merge common functions with
gstformat.c?)
Original commit message from CVS:
don't do queries on error, we don't get many errors these days for which
it is useful
tell us which scheduler we're not finding
Original commit message from CVS:
fixes bug
http://bugzilla.gnome.org/show_bug.cgi?id=90333
and similar.
I'd like to also do s/guchar/gchar/ in the xml functions, any reason not to ?
please comment ;)
Original commit message from CVS:
- Removed bufferpool code and move that to gstbuffer.c
- implemented refcounting on GstData
- implemented new buffer code based on Company's work in the EVENTS2 branch
- added boxed types for GstData/GstEvent/GstBuffer/GstBufferPool
- added refcounting to bufferpools and events
- use lockfree allocation for buffers
- simplified the clock, use lockfree allocation
- use GQueue in GstQueue for faster access to the tail element
- update core plugins to the new event API
Original commit message from CVS:
Added a runtime option to use a dummy threading implementation that uses
NOPs for all synchronisation and threading operations.
Original commit message from CVS:
* fix refcounting tests so that they compile and run, but they fail currently:
gst leaks obscene amounts of memory ;)
* fix plugin loading test so that it only refers to plugins within the gstreamer/
tree
* store gst plugin paths in the registry
* is GST_REGISTRY is set, only use the user registry with the PLUGIN_PATH explictly
specified by the user
* all tests should pass now except refcounting
Original commit message from CVS:
* GST_PLUGIN_PATH gets split into the user registry
* some debugging output in registry rebuilding
* don't go into =build, =inst, etc
* i really don't know what the current idiom is for the plugin test suites, disabling for now
still pending issues: what to do when other plugin paths are passed on the command
line for existing registries. if the existing registries were built against those
paths, the time checks work, but if not they will need to be rebuilt. i have a feeling
they should be rebuilt in any case, but it's a tricky issue.
Original commit message from CVS:
Check to see if the registry is out of date, and if so try to rebuild it.
WIERD THING: trying to run gst-register using system() fails. Apparently child processes
can't link to libs parent processes use? It's wierd, and it could be a libtool issue.
That's probably just as well, it would be better just to use -register's code from within
core and not rely on another binary.
Original commit message from CVS:
Totally rewritten registry handling.
- move the registry save/load code into a gstregistry subclass, this
will make it possible to use other registries (flat file, web based,
RDBMS type, etc..)
- a simple GMarkup xml registry is implemented
- use standard statically linked plugins for core elements.
- GstPlugin has a very well defined set of functions now
A little bytestream hack..
Added more info to -inspect.
Some more debugging info for clocking.
Small cleanups
I use ./gst-register --gst-plugin-path=/opt/src/sourceforge/gst-plugins/gst-libs:/opt/src/sourceforge/gst-plugins/
to register core and gst-plugins now.
Original commit message from CVS:
Added --gst-fatal-warnings, the same as --g-fatal-warnings
It's named differently to avoid conflicting with --g-fatal-warnings, which is parsed
by gtk (which we don't depend on)
Original commit message from CVS:
registry handling changes
read up on it in docs/random/thomasvs/registry if interested
net effect should be transparent; ie. it will keep on working, but will
be more flexible than before. Testing with garnome seems to work now.
Should probably be rewritten completely, together with plugin loading, but
only after we spec it out ;) It's a bit messy.
Original commit message from CVS:
commit to make gstreamer follow the gtk function/macro naming conventions:
GstPadTemplate <-> gst_pad_template <-> GST_PAD_TEMPLATE
and the same for *factory and typefind.
Original commit message from CVS:
* new parser that uses flex and bison
- doesn't do dynamic pipelines yet...
* added GErrors to the gst_parse_launch[v] api
* added --gst-mask-help command line option
* fixed -o option for gst-launch
* GstElement api change:
- gst_element_get_pad
- gst_element_get_request_pad, gst_element_get_static_pad
- gst_element_get_compatible_pad
- gst_element_get_compatible_static_pad, gst_element_get_compatible_request_pad
- gst_element_[dis]connect -> gst_element_[dis]connect_pads
- gst_element_[dis]connect_elements -> gst_element_[dis]connect
* manual update
* example, tool, and doc updates for the api changes
- no more plugin docs in the core docs, plugins require a more
extensive doc system
Original commit message from CVS:
updated popt stuff:
- added 'gst_init_with_popt_table' to gst.h
- added a --silent option to launch to suppress g_object_notify events
Original commit message from CVS:
* warning fixes
* gst_object_set_name (name, NULL) uniquifies the name globally
- needs robusticizing
* gst_elementfactory_make can now take NULL as a second argument
Original commit message from CVS:
allow gst_init(NULL, NULL) to work
this fix was prompted by testsuite/test_gst_init.c, which thomasvs was running
on the autobuilder. they are good after all :)
Original commit message from CVS:
workaround for old popt versions, maybe this is the best way anyway (not alowing
for command line args that are not parsed with popt)
Original commit message from CVS:
first pass at integrating popt into gstreamer
note: you will need popt 1.6.3 or greater (configure checks for this) -- debian
people will either need to patch popt 1.6.2 or install 1.6.3 by hand.
Original commit message from CVS:

Original commit message from CVS:
- added playondemand plugin by Leif Morgan Johnson <lmjohns3@eos.ncsu.edu>
- some fixes to int2float
- aplied a patch from wrobell <wrobell@ite.pl> that is a first attempt at
making automake 1.5 happy (gst now requires automake1.5). It's still not
perfect but it builds.
- Made the schedulers plugable. The default scheduler now lives inside a
plugin.
- Added a new mpeg1/2 parser/demuxer.
- Fixed some compiler warnings in the core libs.
- substantial work to GstThread (hopefully less race conditions). simplified
the code in GstThread a bit. A state change can now also happen in the
thread context.
- reworked the state semantics of a bin. it'll now automatically get the
highest state of its children.
- the autoplugger now nests the threads so that a state change failure of
one thread doesn't make its upstream thread lock.
- GstQueue refuses to go to PLAYING if the sinkpad is not connected. This
way the queue will not wedge in the _get lock.
- GstQueue unlocks its mutexes when going to PAUSED.
- make sure that when all elements in a bin/thread go to PAUSED, the bin
is set to PAUSED too.
- make a parent bin wait for its children to PAUSE before ending the
iteration with FALSE (EOS)
- Some changes to GstPlay to deal with EOS.
- aplied the latest patch from Zeenix to gstrtp.
end result: GstPlay doesn't crash on EOS and the pipeline is now shut down
properly.
Original commit message from CVS:
API docs.
revived _buffer_ref_by_count
fast types for scheduler and bin.
error checking on plugin features;
removed some prototypes that were not implemented (gst_pipeline_iterate
comes to mind)
remove gst_pad_event until we know what it's supposed to do.
remove sinesrc, it wasn't compiles anymore, so...
updates to various elements that used the old event API.
Original commit message from CVS:
gstinfo.[ch], cothreads.c: added initial support for -finstrument_functions
gstbin.c: removed a reference to config.h
gstbuffer.[ch]: added gst_buffer_is_span_fast(), used it in gst_buffer_span
elements/gstfilesrc.c: initial work fleshing out the event handling code
everywhere else: wrapped XML stuff in #ifndef's
Original commit message from CVS:
Lots of modifications to the plugin system.
- Added a GstPluginfeature object that serves as a base class for all
plugin contents.
- changed the plugin API, everyhting is now added with
gst_plugin_add_feature
- typefactories are named now so that they can be located easily and filled
in at plugin load.
- mime types like "video/raw image/raw" are gone for now.
- lots of plugin updates (style and API changes)
- tested with an without registry.
- updates to various tools.
- added a little testsuite to test/show how you can load plugins (4 modes)
Test this one, Almost everything has changed :-)
Original commit message from CVS:
gobject2gtk.h: added g2g_object_get_type() prototype
gst.c: fixed gst_add_paths_func() prototype
gstelement.c: changed some prototypes, added a cast
Original commit message from CVS:
added a default bufferpool factory function. it reuses existing instances of bufferpool if requests are made for existing buffer sizes
Original commit message from CVS:
Replace NO_X conditional compilation with testing whether DISPLAY env
variable is set, and doing gtk_type_init() instead of gtk_init() if not.
Original commit message from CVS:
Added colorization to DEBUG and INFO. Colors are based on categories, with
the strings in _gst_category_colors[] in gstinfo.c See wiki node
GstDebugColors for the actual colors, or /etc/DIR_COLORS works too.
Please comment on the colorization style and ideas in the above wiki node.
Original commit message from CVS:
More work on capsnego proxying. It should be OK now.
Added another testcase enum that shows various capsnego algorithms.
Warn about pads that try to set a capability incompatible with their
padtemplate.
Implemented refcounting and copy_on_write for caps/props.
Original commit message from CVS:
Fix gst_init() so that it doesn't fail when passed two NULLs as parameters.
Was dereferencing the argv pointer to get progname: now defaults to
"gstprog".
Original commit message from CVS:
slightly changed the Makefile.am in videoscale libs.
v4lsrc works again
A little modification to the videotest programm to use a tee element.
added support for multiple paths in --gst-plugin_path=.
added ab ENV variable GST_PLUGIN_PATH to specify extra directories to
look for plugins.
Original commit message from CVS:
Added two options: --gst-plugin-spew will print errors when plugins fail
to load. --gst-plugin-path= will add a directory to the path searched for
plugins.
Original commit message from CVS:
More doc updates
Manual additions: xml/load save of custom XML, debugging, request pads
added a signal to the example plugin
fixed a bug in mp3parse (ifdef 1)
Original commit message from CVS:
Added mthodes to request an element to create pads: gst_element_request_pad*
This can be used to construct a tee and a muxer/mixer/aggregator element.
Moved the tee element to elements/ because it can now be handled with the
new pad request features.
The padfactory also has some changes: a pad can now be of presence REQUEST,
which means that the pad can be requested from this plugin (doh).
Original commit message from CVS:
Handle the tee element like bin, thread, pipeline, so that it can be used
in gstreamer-inspect and gstreamer-launch...
Original commit message from CVS:
Mega update of INFO, DEBUG, and ERROR subsystems, renamed with GST_ prefix.
GST_DEBUG now takes a category parameter, which is the same as GST_INFO
system. They are now called GST_CAT_*. All the GST_DEBUGs are set to 0
for now, we need to go and fix all these eventually.
Original commit message from CVS:
Added DEBUG, INFO, and ERROR systems. Very little code is converted yet.
Policy decisions need to be made as to what kinds of cases get what kind
of response, and what the default ERROR response should be. Right now it
will print out all the information, then have gdb spew a stack trace.
