Original commit message from CVS:
Ensure that the marshaller code #includes glib-object.h, and hence the
neccessary definitions to enable it to compile.
I don't pretend to understand how the marshalling stuff works - I just
know that it clearly needs this #include, or something similar. If there's
a more correct fix, someone else can do it. Possibly this is a
glib-genmarshal bug, but I've not got the time to go into that.
Original commit message from CVS:
Ensure that the gstmarshal.[ch] files are generated in time by generating
both files in the same rule: previously, only the .c would be generated in
time. Don't put the files in dists (add a dist-hook to take them out),
and clean the files when running distclean.
Original commit message from CVS:
Removed the GST_CONFIG_DIR from config.h and made a -D CFLAG for it
instead so that we can do full expansion on the sysconfdir.
Original commit message from CVS:
Reworked the arguments for DEBUG and INFO. Removed -debug-verbose.
Renamed GST_DISABLE_XML to GST_DISABLE_LOADSAVE and added --disable flag.
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:
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:
Updates to cothreads code, including non-working alpha. Changed things a
bit, including PPC. Not having a PPC machine, I need someone to test
these changes and report back whether they worked or not.
Original commit message from CVS:
Adding nasty hack to rules to generate cothreads.{o,lo}, to get dependencies
right. Rules copied from automake, and therefore a bit dependent on automake
keeping doing dependency things the same kind of way, but it should work as
long as automake puts dependencies into .deps/*.P
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:
Fixed buffer flag handling
gstplay used old flag handling
updated some plugins for the new objects/error handling
Fixed a serious buffer error in gst_buffer_append
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:
Reparented everything to GstElement, removing GstSrc, GstSink, GstFilter,
and GstConnection. Also fixed a bug in gst_bin_iterate_func.
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:
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:
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:
Changes made to the DEBUG system. New header file gstdebug.h holds the
stuff to keep it out of gst.h's hair. DEBUG prints out the process id,
cothread id, source filename and line number. Two new macros DEBUG_ENTER
and DEBUG_LEAVE are used to show the entry and exit of a given function.
This eventually might be used to construct call trace graphs, even taking
cothreads into account. This would be quite useful in visualizing the
scheduling mechanism.
Minor changes to various debug messages.
Also sitting in gstdebug.h is a prototypical DEBUG_ENTER that's capable of
performing DEBUG_LEAVE automatically. It does this by utilizing a
little-known GCC extension that allows one to call a function with the
same parameters as the current function. The macro uses this to basically
call itself. A boolean is used to ensure that when it calls itself it
actually runs the body of the function. In the meantime it prints stuff
out before and after the real function, as well as constructing a
debugging string. This can be used eventually to provide call-wide data
on the DEBUG lines, instead of having to replicate data on each call to
DEBUG. More research is needed into how this would most cleanly be fit
into some other chunk of code, like GStreamer (I think of this DEBUG trick
as a separate project, sorta).
Unfortunately, the aforementioned DEBUG trick interacts quite poorly with
cothreads. Almost any time it's used in a function that has anything
remotely to do with a cothread context (as in, it runs in one), a segfault
results from the __builtin_apply call, which is the heart of the whole
thing. If someone who really knows assembly could analyze the resulting
code to see what's really going on, we might find a way to fix either the
macro or the cothreads (I'm thinking that there's something we missed in
constructing the cothreads themselves) so this works in all cases.
In the meantime, please insert both DEBUG_ENTER and DEBUG_LEAVE in your
functions. Be sure to put DEBUG_ENTER after your variable declarations
and before any functional code, not to put the function name in any DEBUG
strings (it's already there, trust me), and put a DEBUG_LEAVE if you care
enough.
Changes are going to happen in the way DEBUGs and other printouts occur,
so stay tuned.
Original commit message from CVS:
Added multiple types to the pads.
Added first preview of the capabilities system.
Autoplugging is seriously broken with these (and other) changes.
