* decode of mp3 to raw pcm also tested
Original commit message from CVS:
A rather large patch:
- changed the API for the padtemplates:
- remove the factories (array of pointers) for the padtemplates,
properties and caps. The static array was a nice idea but converting
all the property values to a gpointer was not a good idea.
float properties were not possible, and casting a gint to a pointer
is not very portable. The new API just uses the _padtemplate_new,
_caps_new and _props_new functions to create the templates.
This has the added benefit that the API is now uniform for static
and dynamic templates and that the code can be made cleaner.
- lots of cleanups in the way the capabilities are constructed (va_list)
- lots of updates for all the plugins (new API)
- docs updates (new API)
- removed the videoraw docs.
Original commit message from CVS:
Modified a lot of plugins to use the caps system.
Modified the caps of audio/raw to our agreed properties.
Added the multidisksrc plugin of Dominic Ludlam
Renamed audiosink/src to osssink/src and updated all the examples using
the old name. Moved oss specific plugins in an oss directory. removed
the old audiosink from the elements/ dir.
removed audioraw.h metadata header files since we now use the properties.
There are still a few plugins that won't build because they include the
old audioraw.h header file. This will be fixed soon.
Make sure the caps are set in the plugins as described by their
padtemplates (this should solve problems with gstmediaplay with various
media files).
*please don't panic when some plugins won't build, just cd manually into
the plugin dirs* This will be fixed soon.
Original commit message from CVS:
Reworked the capsnegotiation function
audiosink now uses capsnego to set its parameters
mpg123/ac3dec use capsnego instead of metadata
Added the beginnings of a testsuite for capsnego.
Original commit message from CVS:
Reworked getregion/pullregion stuff. Region is now specified by a type
(OFFSET_LEN, TIME_LEN, etc.) and two guint64's. They are offset and len,
where offset can be used for the time field, and len would be zero or
the time unit (say, 33ms for video).
Original commit message from CVS:
This is a megapatch with the following changes:
- moved the gchar *name to GstObject, removed the ones in GstElement and
GstPad.
- moved the parent handling completely into GstObject. This cause *all* of
the plugins to fail (except those that used gst_pad_get_parent)
- rearanged the XML save handling.
- GstObject now has a class function save/restore_thyself.
- GstObject has a generic method gst_object_save_thyself, this makes it
possible to fire a signal wehever a new object is loaded. This is needed
so we can add XML save hooks.
- GstXML API has changed slightly. You now have to create a GstXML object
first before you can actually load something. This makes it possible to
attach a signal to GstXML whenever an object is loaded. I'm not sure we
will keep this interface.
- GstObject can now print the path_string without knowing about the GstPad and
GstElement types.
- Added gst_bin_get_by_name_recurse_up to lookup an element in the current
element hierarchy.
- added XML namespaces to the saved pipelines the namespace is:
http://gstreamer.net/gst-core/1.0/
namespaces are needed to distinguish user generated XML from the core XML.
Note that the plugins still contain a macro GST_OBJECT_PARENT that will be
replaced with gst_pad_get_parent shortly.
Original commit message from CVS:
Applied the patch from Sepp Wijnands <mrrazz@garbage-coderz.net> that solves
the 'OSS hangs when opening the device when in use' bug.
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:
Massive build fixup. Will send message to -devel list later with details
on the changes and what they mean for Makefile.am writers. Check
docs/random/omega/build/TODO for a list of things that I had to make sure
of.
NOTE: this requires a complete rebuild of all plugins, since I also
changed the STATE enum to a bitfield instead of sequential numbers.
Original commit message from CVS:
Added an extra signal_cond to queue to make sure that the waiting thread
is woken up. Can somebody with queue problems verifify that this does
improve the situation a bit. I'm suspecting that something else is going
on, like a pthreads bug or something.
Small updates to the fake elements.
Original commit message from CVS:
Updated the manual and the docs.
Removed the esdsink in gst/elements/ we have a real one not in the
plugins dir.
Added more APIs to query the plugins, types and caps. more fields now
have a getter and a setter. This is needed to make gstreamer wrapper
fiendly.
Added gst_element_disconnect beacuse we also have a gst_element_connect
Original commit message from CVS:
Rearranged cothreads sources a bit, added some API docs.
Added some functions needed for gstreamer-inspect.
Added num_sources to fakesink.

Added a check for libjpeg
Added and action for the load menu in gstplay
Fixed drag and drop in gstplay
More verbose errors in gstasyndisksrc
Original commit message from CVS:
Massive, massive update of most source files. I went through and cleaned
up all the warnings that I could, which involved fixing some of the plugins.
The configure.in script was re-arranged and cleaned up so, and a check for
libtool 1.3.5 was added to autogen.sh. Added checks for Gtk and GNOME.
Some plugins were removed from the list of things to build for various reasons.
Added GST_DEBUG_FORCE_DISABLE in gstgetbits, since that's time critical and
even an if() from a DEBUG can significantly increase runtimes.
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:
Cleaned up INFO system some more, added API to select categories, modified
the printout function to print cleanly for GST_INIT info (the default min)
and spew function:line debug_string [element] for everything else.
Eventually could make even that configurable easily enough, just check
against another bitmap instead of checking for == GST_INIT.

and GstConnection. Also fixed a bug in gst_bin_iterate_func.
Original commit message from CVS:
Pending editor changes.
fixes for autoplug of elementary MPEG1 video streams
make sure mp3 types get compiled
videosink changes for xml loading
Original commit message from CVS:
Mostly minor little changes, but two interesting things:
1) removed a pthread_join from the gst_thread_main_loop. commented out
because the thread isn't supposed to run pthread_join, the main process is.
2) Fixed a major bug with cothreads in threads. Had to add MAP_FIXED to
the mmap() of the cothread stack. Presumably the gilbc that ships with
redhat 7.0 now places these mmap requests somewhat randomly. Since they
*must* be exactly where we expect them, it was failing. MAP_FIXED forces
it to put it where we say.
Original commit message from CVS:
More massive changes to the scheduling system. Moved the scheduling code
to gstscheduler.[ch], so an child bin can replace the scheduler.
Introduced the concept of chains, which are subsets of the list of managed
elements for a given manager bin, which get scheduled as separate entities.
gst_bin_iterate_func should be pretty much fixed now, the scheduling code
gets to do all the hard work.
Cothreaded case work in the couple tests I've tried, chained is next.
Original commit message from CVS:
Lots of editor changes:
- restucturing of object creation
- loading of xml files
- visual eye candy: color changes on mouseover
- active object is indicated
- property box changes for boolean and enum types
- property box: create properties per element
- show pads/caps in propertybox
added gst_util_get_bool_arg in gstutils.c

Modified gstbin and gstthread to the new state change macros
Original commit message from CVS:
Fixed a bug in gstbin.c the manager was not detected.
Some other testcases
bin, thread, pipeline use the elementfactory on gst_*_new
Original commit message from CVS:
Implemented some test cases... they all fail :-(
Added a flag to identity to for loop_based behaviour.
Added a signal to fakesink when a buffer is consumed.
Original commit message from CVS:
Fixing two bugs:
1) I had commented out an unlock. duh.
2) changed the _get function to return the buffer rather than call _push
Also uncommented some debugging I'd turned off. Need to solve the verbosity
problem somehow, I think by way of debug levels as well as info levels...
Original commit message from CVS:
Massive scheduling changes (again). Not entirely complete, but getting
closer. Need to think about various scheduling plans that we might want
to produce, and figure out the rules for what is legal, and how to get
the results we need as far as the plan.
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:
Changed the GstPadFactory and added the GstPadTemplate.
The GstPadFactory is an easy way to define a pad with capabilities.
The GstPadFactory is converted into a GstPadTemplate. The template is
used to create new pads and to expose the possible pads used in an
element to the plugin system.
updated mp3parse, mpg123, cdparanoia to the new API.
Rerun gstreamer-register because the XML definition has changed.
Original commit message from CVS:
Implemented the hybrid scheduling system for sources and connections
outside the current Bin. Is a bit hackish in one place, but I'll work out
a way to make that cleaner soon. queue.c in tests now works nicely in all
cases. More to come later.
Original commit message from CVS:
First attempt at rebuilding the type/plugin system
- make sure caps/props are saved in the registry
autoplugging is completely broken.
removed the typefactories and typeids from all the pads in the plugins
XML load/save is ok (be sure to rerun gstreamer-register)
Original commit message from CVS:
Another big set of changes. Connections are now also pullfunc based.
gstqueue has been updated, I don't know of any other connections offhand.
There are still a few things that need doing, specifically the concept
of a source or connection with connections to multiple thread contexts is
not dealt with. This may force us to move the threadstate from the
element to the pad, maybe keeping the element's copy for simple cases.
Then the Bin would create a structure to pass to the cothreaded _wrappers
of any such elements, which would detail the pads that are to be dealt with
by this particular cothread context.
That will speed things up to, since we don't have to look through the list
of all pads for every Src or Connection element for every iteration, we can
simply step through the list provided by the plan. Special case might even
have a single pad pointer sitting there to trump the list, if there's only
one (the common case anyway).
Task 23098 is tracking these changes. The main task 22588 depends on that
subtask, as well as 22240, which is a consistency check on PAD_DISABLED.
Original commit message from CVS:
Changed the way things are scheduled, especially sources. A Src used to
have a push() function, and optionally a pushregion() to deal with async
reads, etc. That whole thing has gone away, in favor of providing a
pull() function for the output (Src) pad instead, ala chain functions.
This makes constructing cothreaded schedules out of non-loop elements
somewhat easier. Basically there was always a question as to which pad
was being dealt with. In the pullregion case, cothread-specific data was
used to try to pass the region struct to the right place, which is a slow
hack. And in general, the push function severely limited the kind of
tricks that could be played when there's more than one output pad, such as
a multi-out file reader with async capabilities on each pad independently.
This changes the way cothread scheduling occurs. Instead of the hack to
deal with Src's by calling their push() function (or optionally the
pushregion(), in certain cases), we now are working towards a general
mechanism where pads are the only thing that are dealt with directly.
An optimization was made in the process of doing this: the loopfunction
actually run as the outer [stack] frame of the cothread is now set more
intelligently in create_plan() based on what kind of element it is. We
now have:
loopfunc_wrapper: used for loop-based elements, it simply calls the
loopfunc in a loop, paying attention to COTHREAD_STOPPING (see
below). It currently does other, soon to be depracated, stuff.
pullsrc_wrapper: wraps a Src that's not loop-based (since your options
are now loop- or pull-based)
There will be a couple more to deal with other cases, such as Connections
and chain-based elements. The general idea is that it's a lot more
efficient to make the decisions once in create_plan than to keep doing
this huge if/else chain in the wrapper. Just choose the right wrapper up
front. It'll be most apparent performance-wise in the case of whichever
element context is switched to first for each iteration, since the whole
wrapper setup is done for every iteration.
The tricky part is that there is now a bit of overloading of the function
pointers in a pad. The current meanings (possibly to change a bit more
soon) are:
chainfunc: as always, chainfunc pointer is mirrored between peer pads
(this may change, and the chain func may end up in pushfunc)
pushfunc: SrcPad: gst_pad_pushfunc_proxy, cothread_switch to peer
SinkPad: none (may take over chainfunc, see below) pullfunc:
SrcPad: Src or Connection's function to construct buffers
SinkPad: gst_pad_pullfunc_proxy, cothread_switch to peer
There are a number of issues remaining with the scheduling, not the least
of which is the fact that Connections are still dealt with the old way,
with _push() functions and such. I'm trying to figure out a way to unify
the system so it makes sense. Following the scheduling system is hard
enough, trying to change it is murder.
Another useful scheduling addition, mentioned above, is COTHREAD_STOPPING.
It's an element flag that's used to signal whatever code is running in
cothread context that it should be finishing up and exiting soon. An
example of this is in plugins/cobin/spindentity.c. All the loops should
now be composed of do/while loops, rather than while(1) loops:
do {
buf = gst_pad_pull(spindentity->sinkpad);
gst_pad_push(spindentity->srcpad,buf);
} while (!GST_ELEMENT_IS_COTHREAD_STOPPING(element));
The reason for this is that COTHREAD_STOPPING may be set before the above
loop ever gets started. It wouldn't do for the body of the loop to never
once get called, that would simply stall the pipeline. Note that only the
core library code is ever responsible for setting and unsetting this flag.
All elements have to do is respond to it by cleanly exiting the loop and
the function holding it.
This is needed primarily to allow iterations to occur properly.
Basically, there's a single entry point in the cothread scheduling loop,
gst_bin_iterate_func() simply switches to this cothread. If the element
in this context is allowed to loop infinitely, nothing would even switch
back to the context from which the iterate() was originally called. This
is a bit of a problem. The solution is for there to be an implicit switch
back to the originating context. Now, even I'm not sure exactly how this
works, but if the cothread that's switched to actually returns, execution
returns back to the calling context, i.e. iterate_func().
COTHREAD_STOPPING is therefore set just before switching into this
(currently randomly chosen) context, on the assumption that it will return
promptly after finishing its duties. The burden of clearing the flag
falls to the various wrapper functions provided by the Bin code, thus
element writers don't have to worry about doing that at all (and simply
shouldn't).
Related changes:
All the sources in elements/ have been changed to reflect the new system.
FIXMEs:
1) gstpipeline.c calls gst_src_push at some point, dunno why, it's
commented out now.
2) any other sources, including vcdsrc, dvdsrc, and v4lsrc will break
badly and need to be modified to work as pull-based sources.
Original commit message from CVS:
Added code to force the gsttypes plugin to load before gstelements, by
simply having gstelements.c request the plugin. Solves some dependency
problems. This is the correct method of doing this for now, though I had
a thought:
Have a static list of hard dependencies that the plugin system is responsible
for satisfying before even trying to load the plugin. Makes plugin design
easier.
Original commit message from CVS:
Reworked AC3 decoder. No seeking yet but at least we do not need ac3parse

A reworked gstplay. Now it is called gstmediaplay. gstplay is a custom
widget that can display media and is to become a bonobo component soon.
put the tables of the mpeg audio encoder in a header file.
maybe faster quantisation for the mpeg encoder.
Original commit message from CVS:
More Docs updates.
Added plugin documentation. I fear we need a gstdoc implementation
that loads plugins and does introspection on them. I think we should
automatically create the docs for the pads and mime types the plugins
provide. Does anyone have enough perl knowledge to add these features? I
allready changed the C code to output the pad definitions but my perl
knowledge is too limited, for now, to implement the rest of the needed
functionality...

Fixes to various elements so that correct types are returned.
Fixed flag collision with GtkObject.
Elements can now suggest a thread. not sure if this is the right way to

A first (rude) attempt at autoplug.
Autoplugging selects appropriate codecs to connect src to sink, adds
them to the pipeline and connect pads.
Autoplugging will run the typedetect plugin if the src pad has no MIME

No autoplugging is done on the src and sink pads, it's hardcoded:
connect 'src to sink'.
No attempt at creating threads.
No attempt at dynamically autoplugging not yet existing pads.
Changes to (some) plugins to properly set their MIME types.

Documentation updates. All standard library objects and standard
elements are documented. Modified some of the elements to more
accuratly report about their arguments so the documentation builds
more reasonable output.

This is a rather large patch. Switched on -Wall compiler flag and fixed
the warnings.

Made queue default bigger.
fixed parsing errors in mp3parse mpeg1parse mp1videoparse: more than 2
zeros and a 1 is also a sync.
fixed MPEG1 video SKIP_PICTURE which caused a segfault. AlienSong now
plays as it should do. Skips are currently ignored and give some error
on the console, need to clean this up.
Original commit message from CVS:
Fixed the queue length (fixed length 5 for now).
fixed mpeg1 video rate control.
AlienSong segfaults sometimes. My other movies don't....

Original commit message from CVS:
More incremental updates. I can now successfully produce an rpm simply by
typing `./autogen.sh;make rpm`. This is good ;-)
Original commit message from CVS:
OK, I think I've got all the .cvsignore stuff taken care of, though we'll
want to fine-tune things as we go, of course. Most of them are the same,
with some exceptions for directories that produce executables (those are
listed by name after the standard ones and a newline for separation).
Original commit message from CVS:
Changed Makefiles to:
detect xaudio (check header xaudio/decoder.h)
detect mmx.h
detect CSS (check if css.c is in plugins/dvdsrc), need something better.
some LDFLAGS had *.la dependencies which failed for libtool
The build is now 100% on my system.
