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:
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:
The typefind function now returns a GstCaps structure instead of a gboolean.
modified some plugins to this new behaviour
Fixed autoplugging for the mpg123 case. When an element is selected in
autoplugging and the caps do not match, another element is selected until the
caps match. only examples/autoplug works because gstmediaplay uses a threaded
setup that does not seem to work with the current scheduling.

da03fde054 WARNING: Don't grab this updated unless you're really, REALLY sure.
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.

Changed the GstPadFactory and added the GstPadTemplate.

The GstPadFactory is converted into a GstPadTemplate. The template is

element to the plugin system.

Original commit message from CVS:
Snapshot of work-in-progress do deal with out-of-bin elements.  Current
system is very likely going to be ditched due to its complexity and the
fact that it doesn't work right now.  More than that, it's generating some
really odd results in my test program, which aren't readily explainable.

If you want to keep a working copy of your working copy (heh), don't update
until this is replaced with a hybrid approach.  This approach will be the
beginning of a plan generator that can construct full hybrid schedules
given hints from various places.

Hybrid means that cothreads are used, but there are chunks of the pipeline
that are actually dealt with by chaining. This can improve speed by
reducing cothread switches (which are much cheaper than thread switches,
but still far from free, about 570 cycles on my PIII), but does carry a
complexity burden.  Luckily, the structure of GStreamer allows that burden
to live entirely in create_plan.  Luck?  I think not ;-)
