Original commit message from CVS:
Some more event flags
some more padquery types
Better debugging in _pad_get_caps
ref the caps before adding them to a padtemplate
Original commit message from CVS:
- move the state_change signal emit to a better place, before changing
the parent state
- also call the parent state change handler in a bin
Original commit message from CVS:
- some pad.h reorg, better grouping of function
- added methods and default implementations to get supported formats,
seek methods/flags and query types.
- implemented pad activation/disabling
- start negotiation in the READY->PAUSED state
- added GST_PAD_IS_USABLE (better name?) to check if a pad can be used
for data transport (check if connected and peerpad is active)
- added query for segment end
Original commit message from CVS:
- added GstEventMask to specify event masks (next set of commits)
- use flags for seek methods (for use in masks)
- removed #if 0 from gstmemchunk.h
Original commit message from CVS:
- Documentation updates, renamed some _ methods because gtkdoc didn't
want to generate docs for them.
- Add some more events for future use.
Original commit message from CVS:
Make sizeof(GstBuffer) independent of config.h and HAVE_ATOMIC_H. This still
needs a more fundamental solution though.
Original commit message from CVS:
- Removed bufferpool code and move that to gstbuffer.c
- implemented refcounting on GstData
- implemented new buffer code based on Company's work in the EVENTS2 branch
- added boxed types for GstData/GstEvent/GstBuffer/GstBufferPool
- added refcounting to bufferpools and events
- use lockfree allocation for buffers
- simplified the clock, use lockfree allocation
- use GQueue in GstQueue for faster access to the tail element
- update core plugins to the new event API
Original commit message from CVS:
- Added a bunch of fast atomic operations on x86 with C fallbacks
- Added the code for refcounting in GstData
- Added a gstmemchunk allocator using atomic operations
Original commit message from CVS:
- Removed unused locking from the cothreads
- use G_*_DECLS in .h files
- remove gstlog.h include from gstobject.h, add to .c files
- removed unused refcounting code from gstobject
- small fixes in #includes
- Added Scheduling policy and priority properties to gstthread so that
SCHED_FIFO and SCHED_RR threads can be constructed.
Original commit message from CVS:
if you can't write to the registry (ie it is root-owned and you are user) and it
is out of date, just ignore it; plugin state will get written to the user reg
Original commit message from CVS:
more protective programming
cothread 0 cleans up higher cothreads if they're still around
use a magic number to protect against mem corruption in the struct
flames welcome
Original commit message from CVS:
ok, my latest added error checking and stuff
this reverts uraeus's patch but should tell us what goes wrong with munmap
Original commit message from CVS:
Fixes suggested by thomasvs to get rhythmbox working with basic threads
- int res;
+ int res = 0;
- res = munmap ((void *) thread, COTHREAD_STACKSIZE);
+/* res = munmap ((void *) thread, COTHREAD_STACKSIZE); */
Original commit message from CVS:
some debug info
remove the preventive munmap
reinstate the other munmap for cothread stocks which really should be there IMO
Original commit message from CVS:
ok, this seems to be the right fix for the basic scheduler.
I'd appreciate it if :
a) someone looks over these minimal changes and tells me if they're done
in the right way (especially the alignment argument ;))
b) others run lots of pipes with basic and tell me if they still have
issues
If all goes well I want to revert to the basic scheduler and do a release
Original commit message from CVS:
Don't seek past the end of the file
Fix a bug where the mapend was incorrectly calculated when we read past
the end of the file.
Original commit message from CVS:
Added a runtime option to use a dummy threading implementation that uses
NOPs for all synchronisation and threading operations.
Original commit message from CVS:
remove the "iterate_started" signal and replace it with pre_iterate and post_iterate callbacks.
Apps can now put a lock around an iterate so they can do stuff on the bin from another thread. much nicer than the signal approach.
Original commit message from CVS:
Whan the buffer is filled, the buffer is kept and added to the queue
when there is room again. Don't do this after a flush.
Original commit message from CVS:
put upstream events in an async queue and resend them at the start of the chain. not working as expected yet but a start
Original commit message from CVS:
Add an event function so that seek events are not forwarded when we
have a cache, seeking in the cache still needs to be implemented though..
Original commit message from CVS:
a couple of fixes here:
- forward eos events to all src pads, even if spider didn't connect them. this ensures that the pipeline will stay in a consistant state even when not all pads are sent data
- don't check for nonnull spider until it is actually needed. it really is null when it has been disposed and this method is called.
Original commit message from CVS:
added a "iterate_started" signal which fires before the iterate of a bin. useful for non-threadsafe operations like seek in threaded pipelines
Original commit message from CVS:
add an optional timeout for when queue blocks. when timeout is reached a GST_EVENT_FILLER is sent downstream
This is needed for gst-player since videosink has to be in the same thread as the ui, and spider blocks when there is no video (thus freezing the ui).
Original commit message from CVS:
only use ranked element factories for autoplugging. This is the only commit that needs to be backed out to reinstate previous behaviour.
Before your spider will work again, you will have to update/rebuild plugins and run gst-register.
Original commit message from CVS:
Created an overridable method for seeking on an element, along with a default
implementation.
make queue flush on discont (not entirely correct)
removed the new_media from the discont event.
Original commit message from CVS:
* fixups in the prop view/controller
* compilation fixes in the player
* add gst-editor to gst-all
* fixes to adder to comply with new osssink sync issues
* alsa fixes, although still 100% cpu is used, yum
* reenable locking of threaded elements, seems to work fine here
* fix a makefile in examples/plugins
Original commit message from CVS:
- The clock_wait now returns the difference between requested time and
unlock time.
- Misc defines like GST_SECOND in gstclock.h
- remove pre/post in gstelement.c until fixed.
- added release_locks to gstelement so that the element can unlock itself
- added some more predefined events.
- added folowing functions to gstpad:
- convert function: get the relation between formats on this pad
- query function: get stats about the pad (position/total/latency)
- internal connect function: find out how this pad connects to other
pad internally to the element.
- generic pad_dispatcher.
- removed the last bits of pullregion
- use release_locks on the queue.
- added some events to queue
- make gstthread use the new release_locks function
- make the scheduler use the new clock_wait functions
- added events to fakesink
- added query functions to filesrc
- swap type and offset in the bytestream seek API to match fseek
- added some event handling in bytestream.
Original commit message from CVS:
* implemented threadsafe property set/get system as discussed in
docs/random/wingo/threadsafe-properties
* some cleanups
* this change will cause binary incompatibilities, better rebuild them plugins
now, off to drink :-)
Original commit message from CVS:
* add gerror to gstplugin.c -- not fully propagated to periphery apis
* fix recursive dir creation in the xml registry
* comment identity props
* fix dependency resolution in lib loading
Original commit message from CVS:
* fix refcounting tests so that they compile and run, but they fail currently:
gst leaks obscene amounts of memory ;)
* fix plugin loading test so that it only refers to plugins within the gstreamer/
tree
* store gst plugin paths in the registry
* is GST_REGISTRY is set, only use the user registry with the PLUGIN_PATH explictly
specified by the user
* all tests should pass now except refcounting
Original commit message from CVS:
* added a get_perms_func to gstxmlregistry that will set _WRITABLE and _READABLE
as appropriate
* added an object property for location so that we can do some cleanup and initialization
Original commit message from CVS:
* GST_PLUGIN_PATH gets split into the user registry
* some debugging output in registry rebuilding
* don't go into =build, =inst, etc
* i really don't know what the current idiom is for the plugin test suites, disabling for now
still pending issues: what to do when other plugin paths are passed on the command
line for existing registries. if the existing registries were built against those
paths, the time checks work, but if not they will need to be rebuilt. i have a feeling
they should be rebuilt in any case, but it's a tricky issue.
Original commit message from CVS:
Check to see if the registry is out of date, and if so try to rebuild it.
WIERD THING: trying to run gst-register using system() fails. Apparently child processes
can't link to libs parent processes use? It's wierd, and it could be a libtool issue.
That's probably just as well, it would be better just to use -register's code from within
core and not rely on another binary.
Original commit message from CVS:
Totally rewritten registry handling.
- move the registry save/load code into a gstregistry subclass, this
will make it possible to use other registries (flat file, web based,
RDBMS type, etc..)
- a simple GMarkup xml registry is implemented
- use standard statically linked plugins for core elements.
- GstPlugin has a very well defined set of functions now
A little bytestream hack..
Added more info to -inspect.
Some more debugging info for clocking.
Small cleanups
I use ./gst-register --gst-plugin-path=/opt/src/sourceforge/gst-plugins/gst-libs:/opt/src/sourceforge/gst-plugins/
to register core and gst-plugins now.
Original commit message from CVS:
merged schedulers
- new file cothreads_compat.h to provide linking to desired cothreads package
- changes in basic and fast scheduler to use cothreads_compat.h
- updated Makefile to build the basic and the fast scheduler from both packages
- removed gststandardscheduler.c - it is not needed anymore
Available schedulers are now 'basic', 'standard', 'fastbasic' and 'faststandard' where the basic ones are built with old cothreads and the standard ones with the new cothreads.
Original commit message from CVS:
* gst_scheduler_factory_make () can accept NULL as the first arg now
* _create () sets the element sched and refcounts the scheduler
* corresponding touchups to gstpipeline and gstthread
Original commit message from CVS:
Header file fix (these ## are needed for multi-arguments) and a fix for gst_props_get() if safe = FALSE (we still need three arguments per fetch)
Original commit message from CVS:
let's not clobber our local variables -- i think this is a good short-term
fix until i get to hacking on the standard scheduler again.
Original commit message from CVS:
* a hack to work around intltool's brokenness
* a current check for mpeg2dec
* details->klass reorganizations
* an element browser that uses details->klass
* separated cdxa parse out from the avi directory
Original commit message from CVS:
- make all _get_list functions return a const reference to original lists and no copy
- redo code accordingly
- fix compile issue in dparam stuff
Original commit message from CVS:
Added --gst-fatal-warnings, the same as --g-fatal-warnings
It's named differently to avoid conflicting with --g-fatal-warnings, which is parsed
by gtk (which we don't depend on)
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.
