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:
patch from jim thornton <jthornton@parc.com>:
Buffer flag symbols are enum values, so |'ing together doesn't do the right
thing, must use GST_BUFFER_FLAG_SET macro
Original commit message from CVS:
* form a semantic representation of the pipeline in preparation for
actual instantiation.
the parser is shaping up quite nicely; it should, in theory, be able to create
all types of pipelines that gstreamer supports
Original commit message from CVS:
add (incomplete) flex/bison-based parser to cvs
the tokenizer is functional, but the grammar definition is bad. this
probably breaks distcheck somehow, but hey.
Original commit message from CVS:
* add notify back to filesrc, it's needed for MVC applications
* remove notify printouts from gst-launch
* cleanup in gst-plugins configure.ac
* some jack updates
* remove SELF_ITERATING flag in favor of SEF_SCHEDULABLE (not a clear name,
but it's what we have for the moment)
* improve parsing of request pad names, no more sscanf
* fixes to the fastscheduler Makefile.am
Original commit message from CVS:
- Remove the propsprivate header file
- Added new API for properties.
- Moved the clock distribution to the scheduler.
- Removed the lock from GstCaps
- Added boxed types for Caps/Props
- Simplified the clock, new systemclock implementation
- Removed deprecated element_info/send_event functions
- First step at exposing more info in the pad_connect functions
- Queue cleanup
- Make the scheduler aware of other schedulers inside it
- Added the _SELF_SCHEDULABLE flag to gstthread
- Removed _get_widget from _utils, changed to new props API
- Make fakesink sync on timestamps when requested
- Removed the offset notify from filesrc
- Added a fast scheduler
- some scheduler cleanups.
Original commit message from CVS:
apply patch from jim thornton <jthornton@parc.com>:
"bugfix for intersecting int list with int range: the proper intersection
should be those ints in the list that lie within the range (rather than an
empty intersection)."
the reverse of this case doesn't exist, because if the entry1 is a list,
the members are broken out and tested seperately, therefore the intersection
would be int <-> int range, which does work.
Original commit message from CVS:
* added plugin_desc structures to libs, which makes their locations cached in the registry. this
speeds plugin loading considerably, especially on uninstalled versions.
* put the lib path before all others, for speed reasons.
* some fixes to adder's caps.
* added linefeeds (\n) to GST_DEBUG strings to match GST_INFO behavior. this is more sane. all
code will need to be converted. i think some perl can do this.
Original commit message from CVS:
s/POINTER/OBJECT/ in g_signal_new for NEW_PAD and PAD_REMOVED.
Very important for python bindings to know it's getting an GObject
vs a boxed anonymous pointer.
Original commit message from CVS:
* removal of //-style comments
* don't link plugins to core libs -- the versioning is done internally to the plugins with the plugin_info struct,
and symbol resolution is lazy, so we can always know if a plugin can be loaded by the plugin_info data. in theory.
Original commit message from CVS:
s/@GST_PLUGIN_LDFLAGS@/$(GST_PLUGIN_LDFLAGS)/
@-substitued variables variables are defined as make variables automagically,
and this gives the user the freedom to say make GST_PLUGIN_LDFLAGS=-myflag
Original commit message from CVS:
* s/gst_element_install_std_props/gst_element_class_install_std_props/ -- it just makes more sense that way
* added jack element, doesn't quite work right yet but i didn't want to lose the work -- it does build, register,
and attempt to run though
* imposed some restrictions on the naming of request pads to better allow for reverse parsing
* added '%s' to reverse parsing
* added new bin flag to indicate that it is self-iterating, and some lame code in gst-launch to test it out
* fixen on launch-gui
* added pkg-config stuff for the editor's libs
Original commit message from CVS:
added gst_util_set_value_from_string.
this could probably be refactored with gst_util_set_object_arg at a later date.
Original commit message from CVS:
* document gst_caps_debug
* change gst_caps_debug to accept a label argument, assists greatly
in debugging capsnego
* better names from gst_object_name_default
* some more debugging in gstpad.c
* require caps to match padtemplates on both side of a connection
* gstspider uses default naming so that names are globally unique
* moved filesrc offset arg to the top -- show up first in a prop list.
in the future we should have flags on props indicating which ones
it might be interesting for the end-user to change.
* initialize cothreads in the more standard way, and provide some more debugging
Original commit message from CVS:
make sure cothread->priv is NULL when uninited because we now check it
(added debugging line to gst_bin_remove while debugging)
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:
Store the element in the cothread private field.
If we remove the current entry in the cothread chain, make sure another
cothread is marked as COTHREAD_STOPPING.
Original commit message from CVS:
* add two apis:
* gst_element_connect_elements_many (elem1, elem2, ...)
- calls gst_element_connect_elements() in order
- should be called gst_element_connect_many, but we need to rename gst_element_connect_elements first
- simplifies common-case code
* gst_bin_add_many (bin, elem1, ...)
- calls gst_bin_add on all of the elems
- again, simplifying common code
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:
* a warning fix
* a potential commenting error fix
* more debug output when trying to set caps so I can actually tell from it
what's going on
Original commit message from CVS:
Fixed some warnings
Always recalculate caps intersection in perform_negotiate 'cause they
might have changed. (needs better solution probably)
Original commit message from CVS:
* changes to spider:
* add padtemplates so the connect functions can connect two request-pad
elements
* add a hack in gstelement.c. please look at this, Company, and see how
we can get around this
* add backwards caps-propagation support in identity, int2float, float2int,
adder, speed, volume
Original commit message from CVS:
* many fixes related to dynamic pipelines.
* addition of gst_element_disconnect_elements(), as per connect_elements()
* don't have a cow if typefind changes state in its signal handlers
* support of request pad -> request pad in connect_elements()
* some fixes in int2float that will eventually need to be ported to float2int and
adder
the gstelement api is getting bloated, expect a rewrite within the next month.
Original commit message from CVS:
appending caps to themself is not fatal, is it?
If it is, revert the patch, but please allow gst_caps_append (NULL, NULL);
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:
to set default categories for an app, call set_categories before the gst_init
restores gst-register to its previous verbosity (but --gst-mask=0 works)
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:
revert part of wingo's patch
wingo, I'm not doing this to piss you off ;)
but with your change we get the reverse issue : stuff in libs/gst needs
gstmarshal.[ch], which are only generated if we go in gst before libs.
So unless we just throw the egg at the chicken we'll have to settle for a
hack.
Alternatively, we could take the egg out of the chicken and put it in
a separate tarball which would then be installed ;)
Original commit message from CVS:
fix funny build issue by not linking plugin libraries to gstreamer core. this is
because they are plugins, not shared libraries per se, and will only be loaded by
the core itself. this change allows the core elements (schedulers, autopluggers, etc)
to use the core loadable libraries (bytestream, getbits, etc) as well as "ext" libs
like the new cothreads package.
Original commit message from CVS:
I don't think we wanted to change the include dir to gstreamer as well.
If we did, then we need major code cleanups all over so let's hold off for
a second.
Original commit message from CVS:
this is a really evil hack.
I would like for someone to help wingo and me fixing it properly ;)
and for that I could use a little basic education on some of the LD FLAGS
we need all over because trying to fix it properly got me confused.
Original commit message from CVS:
major rewrite of the spider.
Now uses GstSpiderConnection to track current connections and remember the way they're plugged.
Advantages of this approach:
- function prototypes are now much cleaner.
- Allow event propagation (EOS) to elements that are not connected but plugged.
- Allow deconstruction of plugged pipes. (not implemented)
Disadvantage:
- I screwed up naming (always get src and sink the wrong way). It's very inconsistent in the gstspider.[ch] files
- a little more time and memory are needed to manage the structs
Original commit message from CVS:
* removed cothread-specific code from gstinfo.c because the new cothreads has no cothread_self()
* added a new scheduler, untested but it does compile :-)
* cothreads links to the scheduler, not core now
* no installation of cothreads headers
Original commit message from CVS:
This patch (nearly) completes the removal of vertical events from the
core.
What it does:
- removal of the EVENT signal of GstElement (to be replaced by
g_object_notify)
- changing of the ERROR signal to allow recursive notification (like
deep_notify)
- implementing recursive notification with error events.
- removal of some functions in gstbin.c that are not used anymore.
- The function gst_element_info and gst_element_send_event now do
nothing but printing a warning, that these functions are gone. This is
done to allow plugins to catch up.
- Some bugfixes in XML saving are included, they simply were in the
file.
Original commit message from CVS:
initial checkin for the deep_notify signal which replaces INFO events in the long run.
PLEASE do not use gst_element_[info,message,error] anymore. Use g_object_notify instead.
Thank you.
Original commit message from CVS:
this fix makes sure that we actually request a pad from the template with
an unused name
this isn't optimal but gets the job done
should we move this code fragment to it's own helper function to use
everywhere stuff is requested according to a template ?
Original commit message from CVS:
- use autoplugging instead of predefined way on sometimes pads
- exchange plugtype with factories in the spider
- revamp the spider, now messier than before...
- bugfixing
- style corrections
Original commit message from CVS:
Added a first stab at a better clocking system.
It still needs more infrastructure for async notification and custom clock
implementors.
This thing can still deadlock the pipeline.
Original commit message from CVS:
some compile fixes, api changes, and i added the ability to create new chunks on the
stack, which can extend the main thread's stack up to 8M under linuxthreads. thanks
to billh for the {set,get}rlimit tip.
on the other hand, there's a nasty bug in cothreads when they are run without gthreads
that i'm still tracking down. that's the last bug though, at this point.
the commit is to syn the repository with my working copy before moving cothreads to a
separate module.
Original commit message from CVS:
Change soversion back to 0:0:0 and add use of -release flag for libtool.
This means that any program linking against libgst will automatically have
the specific release of libgst encoded into it. This enforces the fact
that (for the moment), the API/ABI is changing rapidly enough that you
can't link against 0.3.2 originally and have it still work with 0.3.3. It
might be possible, but highly unlikely.
When we get closer to a stable API/ABI, in the 0.5.0 timeframe most likely,
we will start using soversions as recommended in the libtool docs. Then
we have to pay more attention to forward and backwards compatiblity, or
rather, we have to *start* paying attention <g>
Original commit message from CVS:
fixed a number of bugs, added support for cothread-private data and
functions of the form void (*func) (int argc, void **argv)
the test app demonstrates the thread-safety of the cothreads lib
this is shaping up to be pretty solid.
Original commit message from CVS:
* a first pass at cleaning up the configure stuff
* new cothread library started, some experimental stack allocation code is in place
Original commit message from CVS:
should fix an error in a no-glib2 error message, an error in libxml stuff
(newer versions of libxml1 can be included as libxml/parser.h), and silencing
a warning in the cothreads stuff
Original commit message from CVS:
new, shiny hack uses mutexes to determine the current pthread_descr
without resorting to internal header files. muahaha ;)
this is only for linuxthreads, of course.
Original commit message from CVS:
added a test for pth and pthreads. in summary, it doesn't work because
in __pthread_find_self() some funny stack pointer math is done that
will result in no matches for __pthread_find_self(). this is dereferenced in
__errno_location, causing a segfault on context switch because of the errno-swapping
on the part of pth. it's a mess and i don't know how to get around it. i'll
have to look into what ngpt does for looking up errno, as it has kernel threads as
well as user threads.
Original commit message from CVS:
The core code from pth has been taken out and included in gstreamer.
This code is documented, more or less, in http://www-124.ibm.com/pthreads/docs/rse-pmt.ps.
This code is designed to replace cothreads.[ch], eventually.
Original commit message from CVS:
Delay pad negotiation until the element is in READY or higher. this will
gice the element a chance to open its devices before we start calling the
connect functions.
Make sure we use the real pad in the negotiation.
Some other small cleanups.
Original commit message from CVS:
miscellaneous fixes, added gst_pad_unset_sched() api.
although I unref the old pipeline and the cothread context gets freed in dynamic-pipeline.c,
I still get segfaults.
Original commit message from CVS:
* cleaning up duplicated code in gstbin.c
* added some sanity checks in gstpad.c
* added checks for failed connections in gstparse.c
* better docs in gstxml.c
Original commit message from CVS:
Previously filesrc would segfault when fed with the name of a directory.
Added check to ensure that the given file is a regular file.
Original commit message from CVS:
* fix doc build for glib2
* remove template files from cvs, they are generated with gtkdoc-mktmpl
* new, cleaner interface to the parser facilities
* cleanups in gstparse.c
Original commit message from CVS:
Landed the new improved capsnegotiation system.
The main idea is to keep track of the possible data types that can
pass through a connection. plugins can at any time inspect, adjust and
refine these caps. plugins also get notified when something changes to
the types so that they can reconfigure themselves.
Look at the updated plugins and the soon to be finished doc.
Original commit message from CVS:
* s/filter/plugin/
* add $(GST_LIBS) to all plugins
* move Makefile.am things around to a mostly standard layout
* remove HTTP flags/libs from elements since http element moved
Original commit message from CVS:
summary: fix xml in gstreamer
1) make clear distinction between loading xml that actually creates objects and loading xml that just
synchronizes properties with objects. moved most of gst_element_restore_thyself functionality to
gst_xml_make_element. this new function name can change if it sucks.
2) many various fixes. createxml and runxml work now.
3) doc updates.
4) GstSignalObject is stil broken. i have no idea what it's supposed to do.
Original commit message from CVS:
added function gst_xml_write_file() which writes a nicely formatted and indented
xml representation of an element to a file. you can use stdout or stderr, for
example.
Original commit message from CVS:
fixes for make distcheck
does GST_ELEMENT_IS_COTHREAD_STOPPING still exist ?
and if so, how should it be found by the bytestream test ?
Original commit message from CVS:
fixes to make distcheck work
changed registry out of date to warning to allow tests to continue regardless (any better suggestions much appreciated)
Original commit message from CVS:
Some small cleanups.
added a drop_probaility arg to identity, so it occasionally can drop buffers
to simulate network packet loss
