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:
- 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.
Original commit message from CVS:
Cleanup in gsttypes.c:
removed the crazy GList of GHashTables, since the autoplugger will
use the GstCaps and elementfactories instead of the type system.
We don't maintain a list anymore of the elements for the specific
removed unused code in XML loading/saving.
Cleanup in gstelementfactory:
removed the register/unregister methods, register is now implicit when
gst_elementfactory_new is called. _unregister is now _destroy.
Removed logic to register/unregister the types in gsttypes.
added methods to query if the factory can src/sink a GstCaps
Make sure the elementfactory is set in the element_class when a new
element is registered with gst_elementfactory_new.
gst.c: properly register the basic bins
gst_pipeline: use new gstautoplug (next checkin)
gstprops: fixed an error in compatibility check
registry test program changes
plugins: misc changes for the new caps system.
Original commit message from CVS:
WARNING: Don't grab this updated unless you're really, REALLY sure.
WARNING: Wait for the next one.
Whole lotta changes here, including a few random bits:
examples/*/Makefile: updated to use `libtool gcc`, not just `gcc`
gst/
gstbuffer.h: updated to new flag style
gst.c, gstdebug.h: added new debugging for function ptrs
gstpipeline.c: set type of parent_class to the class, not the object
gstthread.c: ditto
plugins/
cdparanoia/cdparanoia.c: added an argument type, updated some defaults
cobin/spindentity.c: updated to new do/while loopfunction style
mp3encode/lame/gstlame.c: argument types, whole lotta lame options
tests/: various changes
Now, for the big changes: Once again, the scheduling system has changed.
And once again, it broke a whole bunch of things. The gist of the change
is that there is now a function pointer for gst_pad_push and gst_pad_pull,
instead of a hard-wired function. Well, currently they are functions, but
that's for debugging purposes only, they just call the function pointer
after spewing lots of DEBUG().
This changed the GstPad structure a bit, and the GstPad API as well.
Where elements used to provide chain() and pull() functions, they provide
chain() and get() functions. gst_pad_set_pull[region]_function has been
changed to get_pad_set_get[region]_function. This means all the elements
out there that used to have pull functions need to be updated. The calls
to that function have been changed in the normal elements, but the names
of the functions passed is still _pull[region](), which is an aesthetic
issue more than anything.
As for what doesn't work yet, just about anything dealing with Connections
is hosed, meaning threaded stuff won't work. This will be fixed about 12
hours from now, after I've slept, etc. The simplefake.c test works in
both cothreaded and chained cases, but not much else will work due to the
Connection problem. Needless to say, don't grab this unless you *need*
these features *now*, else wait to update this stuff until tomorrow.
I'm going to sleep now.
Original commit message from CVS:
Header cleanup: try to include as little as possible; this will probably
speed up compilation a bit.
changed the .c files to use #include "..."
Fix for the 'plugins are loaded twice' bug.
Fix 22186: GstObject flags are now used everywhere. Added *_FLAG_LAST so
elements do not use the same flags. Added some padding in the flag enum
for future expansion.
Original commit message from CVS:
Make sure the Gdk thread lock is not held inside the gstreamer pipeline.
Fix the videosink to not hold the Gdk lock when emitting a signal.
All Gtk GUI apps using GStreamer should now handle the Gdk locks when
handling signals from the pipeline (as it should be)
Original commit message from CVS:
Due to popular demand :-), I added a vorbis decoder.
The encoder is not yet functional.
Small cosmetic changes to gstcpu.c
Beware:
You *need* to install libvorbis.a from the main vorbis CVS.
you *have* to change the line in libtool to
deplibs_check_method="pass_all"
because else the plugin shared library refuses to link against the
static libvorbis.a library. This is a hack. I have no intention in
including libvorbis into the gstreamer CVS tree and making it
libtool compatible.
Original commit message from CVS:
Added CPU detection.
Added SSE optimisation to mpeg_play
Modified the mpeg2 decoder and gstidct to use cpu detection.
Cleanups in the mpeg1 and mpeg2 decoders.
