Original commit message from CVS:
Updates to DEBUG system: moved statename into gstelement.c, colorized the
states:
NULL: white
READY: read
PAUSED: yellow
PLAYING: green
Original commit message from CVS:
Slighly take a different approach for object destruction, using the real
_remove functions so that the scheduler has a chance to destroy its state
too.
This breaks the thread with ghostpads destruction case for now.
Original commit message from CVS:
slightly different refcount handling. the pad shutdown function doesn't
remove the pad from the parent because the parent is needed in the destroy
function.
Original commit message from CVS:
cothreads.c: added a comment on one of the tests
gstbin.h: added the GST_BIN_SELF_SCHEDULABLE flag
gstelement.c: cleaned up the _change_state function a little
gstobject.c: improved the refcounting DEBUGs
gstpad.c: moved the connected signal to after capsnego,
added the caps_nego_failed signal
gstpad.h: added the caps_nego_failed signal funcptr
gstscheduler.c: added the GST_BIN_SELF_SCHEDULABLE exception
gsttypefind.c: added check code around signal_emit to deal with the case
where the signal's handler shuts down the element
gstautoplugcache.c: added the first_buffer signal and caps_proxy arg
gstautoplugger.c: significant rework, it functions quite nicely actually
Original commit message from CVS:
Converted the DEBUG system to look like the INFO system, with a function
pointer that can be replaced. Not done with everything, since it seems
that we need an ERROR system plus a FATAL error, or maybe just an ERROR
system with a severity, and depending on this the DEBUG system might again
be changed to have a single or at least fewer handlers.
Also did a bit of work fixing up the actual DEBUG and INFO commands
scattered throughout the code. We still have over 500 of these in gst/*.c
alone...
Original commit message from CVS:
Updated the colorization a bit more, and did a significant pass through all
the other code to change categories on DEBUG and INFO statements to be
correct, and not simply zero. There are still more, but this is a good
first pass.
Original commit message from CVS:
Added element-level locking support, implemented for cothreads with a mutex
held whenever an element is actually currently running. This should be done
with atomic variables eventually, but the best I can find is to use
<asm/spinlock.h> from the kernel, which brings in too much for my taste.
Also increased cothread stack size to 32KB and max cothread count to 64,
which fits within the default pthread 2MB stack. It would probably be good
to do a pthread_attr_getstacksize() to verify that it's 2MB, and if
linuxthreads had a pthread_attr_setstacksize(), we could remove these
limits.
Original commit message from CVS:
Significant progress. Now able to do most operations live, without any
failure. tests/incsched.c currently faults at the last iteration, not
yet sure why.
Original commit message from CVS:
First round of incremental scheduling. Manager setting and managed_elements
lists are now handled at bin_add/remove time. Scheduling chains can be
created incrementally as well, though there are still some pieces missing.
Original commit message from CVS:
Added a first attempt for XML embedding in the main core XML.
Objects will emit a signal that a user app can connect to in order to
insert its XML into the tree.
You can catch the object_loaded signal in GstXML to parse the user
supplied XML data in the stream. The object_loaded signal is implemented
with a custom made class signal. All GstObject classes now automatically
create a GstSignalObject that serves as a proxy to the user app when an
object is loaded. All objects are currently responsible to emit the
class signal themselves.
runxml and createxml serve as an example how the XML hooks can be used to
insert and retrieve custom XML tags.
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:
Add gst_element_request_compatible_pad and remove gst_element_request_pad.
Implemented something reasonable for gst_element_request_compatible_pad,
but havn't tested much: it won't work for tee because the pad templates
have no caps, and negotiation is not yet written, so it is assumed that the
tee pads can't connect to anything.
Original commit message from CVS:
More EOS changes.
When a bin2 is found inside a bin1, we add the bin2 to the EOS providers
of the bin1. When there is nothing more to schedule in bin1 and bin2 has
fired EOS, bin1 is in EOS.
The queue overrides the EOS notification and calls EOS on the src pad
when the queue is empty and the sink pad is in EOS.
Original commit message from CVS:
A very small change to make eos somewhat work. no inner bins are checked.
When an element fires EOS, the chain with that element is removed from
the scheduler (marked inactive). If all chains are inactive, the bin
fires EOS.
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:
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:
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:
Started work on better ghostpad management, and started to build the low-
level EOS mechanism.
Also removed a couple of printouts that aren't needed any more.
Original commit message from CVS:
Docs updates: remove sink, src, filter, connection
added gstinfo to docs.
Updated some core files for the docs
gsttypefind did not include gst_private
Added CFlags to Makefile.am in gst/elements
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.
