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.
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:
Added handoff signals to fakesrc and fakesink
Added scheduling property to identity
Added GST_STATE_TRANSITION macro to check for state changes.
Modified gstbin and gstthread to the new state change macros
Original commit message from CVS:
Massive scheduling changes (again). Not entirely complete, but getting
closer. Need to think about various scheduling plans that we might want
to produce, and figure out the rules for what is legal, and how to get
the results we need as far as the plan.
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:
Implemented the hybrid scheduling system for sources and connections
outside the current Bin. Is a bit hackish in one place, but I'll work out
a way to make that cleaner soon. queue.c in tests now works nicely in all
cases. More to come later.
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 ;-)
Original commit message from CVS:
Another big set of changes. Connections are now also pullfunc based.
gstqueue has been updated, I don't know of any other connections offhand.
There are still a few things that need doing, specifically the concept
of a source or connection with connections to multiple thread contexts is
not dealt with. This may force us to move the threadstate from the
element to the pad, maybe keeping the element's copy for simple cases.
Then the Bin would create a structure to pass to the cothreaded _wrappers
of any such elements, which would detail the pads that are to be dealt with
by this particular cothread context.
That will speed things up to, since we don't have to look through the list
of all pads for every Src or Connection element for every iteration, we can
simply step through the list provided by the plan. Special case might even
have a single pad pointer sitting there to trump the list, if there's only
one (the common case anyway).
Task 23098 is tracking these changes. The main task 22588 depends on that
subtask, as well as 22240, which is a consistency check on PAD_DISABLED.
Original commit message from CVS:
Fixed a dumb mistake: in gst_element_set_loop_function, it was forcing
the cothread's entry function to change. This is totally wrong, the
create_plan function in GstBin is responsible for setting that to its
own internal helper function. Code removed outright...
Original commit message from CVS:
Closed 22145 - gstelement.c: support hotswapping of loopfunc
Added a flag GST_ELEMENT_NEW_LOOPFUNC that's set when a new loopfunc is set,
which needs to be obeyed by the loopfuncs themselves. The assumption is
that only a loopfunc or an element that knows what it's doing will ever
change the loopfunc pointer, so they can be responsible for exitting
the loopfunc itself appropriately.
The loopfunc_wrapper function has been changed to call the loopfunc
pointer itself in a loop. If the loopfunc changes, the current loop is
supposed to exit, which causes the loopfunc_wrapper to start up the new
loopfunc.
Original commit message from CVS:
Closed task 22143 - gstelemnt.c: complete gst_element_connect
SImple matter of cleaning up the conflicting checks and actually
connecting the pads in question.
Original commit message from CVS:
gstbin.c: modified so create_plan occurs after the state change of all the
child elements.
gstelement.c: set_state now loops such that each element only deals with
one state change at a time, i.e. NULL->READY,READY->PLAYING,
instead of a single NULL->PLAYING.
Original commit message from CVS:
Docs updates.
Added LICENSE info to headers/code where missing in gst directory
Added a bonobo wrapper for the media player (it shows up in gshell but
locks up when activating the component, anyone?)
Fixed some XML save/load problems with arguments.
Original commit message from CVS:
More Docs updates.
Added plugin documentation. I fear we need a gstdoc implementation
that loads plugins and does introspection on them. I think we should
automatically create the docs for the pads and mime types the plugins
provide. Does anyone have enough perl knowledge to add these features? I
allready changed the C code to output the pad definitions but my perl
knowledge is too limited, for now, to implement the rest of the needed
functionality...
Original commit message from CVS:
Loading and saving of XML pipeline descriptions.
GladeXML like operation implemented (you can retrieve parts of a pipeline)
Original commit message from CVS:
Due to popular demand :-), I added a vorbis decoder.
The encoder is not yet functional.
Small cosmetic changes to gstcpu.c
Beware:
You *need* to install libvorbis.a from the main vorbis CVS.
you *have* to change the line in libtool to
deplibs_check_method="pass_all"
because else the plugin shared library refuses to link against the
static libvorbis.a library. This is a hack. I have no intention in
including libvorbis into the gstreamer CVS tree and making it
libtool compatible.
Original commit message from CVS:
A first (rude) attempt at autoplug.
Autoplugging selects appropriate codecs to connect src to sink, adds
them to the pipeline and connect pads.
Autoplugging will run the typedetect plugin if the src pad has no MIME
type.
No autoplugging is done on the src and sink pads, it's hardcoded:
connect 'src to sink'.
No attempt at creating threads.
No attempt at dynamically autoplugging not yet existing pads.
Changes to (some) plugins to properly set their MIME types.
Original commit message from CVS:
Megapatch, changes which states are available, how they're used, and how
they're set. Also modifies the scheduling system, breaking pulled
buffers. Check mail archives for more details.
Original commit message from CVS:
This is the audio/video sync release.
Changed the mpegvideoparser to parse complete pictures. Added the PTS
timestamps to the pictures.
Added PTS timestamps to the MPEG audio frames.
Made the clock a littlebit better.
Gstplay now uses two more threads one for video, one for audio playback.
Added the first QoS callbacks for the pads.
hopefully fix an mmx compilation problem.
Original commit message from CVS:
Added MMX optimized yuv2rgb (AlienSong now plays back at only 6% CPU)
Added mpeg1 picture skipping and fixed a buffer overflow.
Added a system clock. The audiosink can now adjust the clock.
Fixed incorrect behaviour on 8, 15, 16, 24 and 32 bits displays.
Cleanup of the videosink, it now uses the color conversion library when
needed.
Original commit message from CVS:
Documentation updates. All standard library objects and standard
elements are documented. Modified some of the elements to more
accuratly report about their arguments so the documentation builds
more reasonable output.
Added aviencoder and jpegencoder elements (not working yet)
Original commit message from CVS:
This is a rather large patch. Switched on -Wall compiler flag and fixed
the warnings.
Made the Video for Linux more like it should be.
Original commit message from CVS:
Compile a test program to ensure that we have working atomic resource
counting.
A few small changes (include headers, fix a cast) to stop compiler
warnings.
