Original commit message from CVS:
added unitconvert which has a registry of Units of Measurement and an api to convert one unit to another.
Any required dparam now needs to specify what unit it represents so that an app can convert it to some other unit for presentation/other purposes.
Also added GST_DPMAN_PROCESS_CHUNK macro for elements which don't process their audio one sample at a time (ie, ladspa).
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:
Added a signal which notifies when a required dparam is added.
Added gst_dpman_bypass_dparam so that some dparams can be exposed as object properties as well. If the object property is set, a connected dparam is disconnected to avoid the two subsystems fighting over setting the value.
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:
* 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:
This is a major update to the dparams api - I think it is now much cleaner and the app-side is much easier to use.
highlights are:
- GParamSpecs are now used throughout to define dparams
- currently limited to supporting types gfloat, gint and gint64. this should cover 99% of cases and new types can be added in the future
- application-side api is now based almost entirely on setting object properties
- the smoothing dparam is now a subclass of GstDParam
- array-mode is not yet implemented but is not forgotton
time to start documenting
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:
- plugins are built without versioning info /Uraeus claims: plugins/;
if not plugins why this is built as lib*.so.0.0.0?
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:
- added playondemand plugin by Leif Morgan Johnson <lmjohns3@eos.ncsu.edu>
- some fixes to int2float
- aplied a patch from wrobell <wrobell@ite.pl> that is a first attempt at
making automake 1.5 happy (gst now requires automake1.5). It's still not
perfect but it builds.
- Made the schedulers plugable. The default scheduler now lives inside a
plugin.
- Added a new mpeg1/2 parser/demuxer.
- Fixed some compiler warnings in the core libs.
- substantial work to GstThread (hopefully less race conditions). simplified
the code in GstThread a bit. A state change can now also happen in the
thread context.
- reworked the state semantics of a bin. it'll now automatically get the
highest state of its children.
- the autoplugger now nests the threads so that a state change failure of
one thread doesn't make its upstream thread lock.
- GstQueue refuses to go to PLAYING if the sinkpad is not connected. This
way the queue will not wedge in the _get lock.
- GstQueue unlocks its mutexes when going to PAUSED.
- make sure that when all elements in a bin/thread go to PAUSED, the bin
is set to PAUSED too.
- make a parent bin wait for its children to PAUSE before ending the
iteration with FALSE (EOS)
- Some changes to GstPlay to deal with EOS.
- aplied the latest patch from Zeenix to gstrtp.
end result: GstPlay doesn't crash on EOS and the pipeline is now shut down
properly.
Original commit message from CVS:
Patch from vishnu:
The attached patch adds event support to bytestream. Here's how it
works: When bytestream encounters an event, the event is saved and
it returns NULL. Then you must call a new API to retrieve the event
and handle it:
void
gst_bytestream_get_status (GstByteStream *bs,
guint32 *avail_out,
GstEvent **event_out);
Whatever is necessary to handle the event is left up to the plugin.
Once the event is retrieved then the bytestream continues as usual.
Original commit message from CVS:
Applied vishnus patch:
* Check all return codes and reliably return NULL if no more data is
available.
* Split _flush into _flush/_flush_fast. This is partly to make the code
self-documenting -- the flush in gst_bytestream_read cannot fail. Also,
this is a slight optimization.[A
Original commit message from CVS:
- basic arch check for HAVE_RDTSC
- use common gst_trace_read_tsc() for RDTSC call
- add untested function to do ascii dump of trace data
Original commit message from CVS:
Fixed a few plugins so that mpeg1 encoding sorta works.
Added an mpeg1 encoder example, it uses the autoplugger to convert
the stream to audio/video, which is then fed to the encoders.
Original commit message from CVS:
Lots of updates to the plugins for caps negotiation.
Added YUY2 output to the win32 dlls.
Added a colorspace converter in gstplay
Original commit message from CVS:
A rather large update:
- a new videosink using plain X windows (xvideosink). It uses capsnego to
set up it's formats.
- gstplay uses the new xvideosink and a gtk_socket. The initial window
size is set to 0x0 so you need to resize it before you see something.
- got rid of the video metadata include file in favour of properties and
caps negotiation
- adjusted most plugins to not use the metadata.
Original commit message from CVS:
Refreshed the winloader with the latest xmmp code.
win32 codecs work again. It was a metter of turning of optimisations.
Original commit message from CVS:
slightly changed the Makefile.am in videoscale libs.
v4lsrc works again
A little modification to the videotest programm to use a tee element.
added support for multiple paths in --gst-plugin_path=.
added ab ENV variable GST_PLUGIN_PATH to specify extra directories to
look for plugins.
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:
Massive, massive update of most source files. I went through and cleaned
up all the warnings that I could, which involved fixing some of the plugins.
The configure.in script was re-arranged and cleaned up so, and a check for
libtool 1.3.5 was added to autogen.sh. Added checks for Gtk and GNOME.
Some plugins were removed from the list of things to build for various reasons.
Added GST_DEBUG_FORCE_DISABLE in gstgetbits, since that's time critical and
even an if() from a DEBUG can significantly increase runtimes.
Original commit message from CVS:
Various fixes to ensure that appropriate files are included in make dist.
Make dist now produces a nearly functioning distribution.
Original commit message from CVS:
Added seeking to the avi decoder by implementing pull_region.
Fixes to the asyncdisksrc.
Added thread specific data to the cothreads.
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:
Fix compile problem due to DEBUG being redefined in
libs/getbits/gstgetbits.h. Also fix several small typos in the docs and
examples.
Original commit message from CVS:
Added gst_pipeline_add_sink/src to allow multiple sink cases and
more complex autoplugging. Update docs too.
Simplified the pipeline autoplugging code.
Changed the cothread case: One iteration is now a push from the src
element. The disk source does not change its state anymore on eof.
Better type setting for the ac3 parser/decoder and mpeg2parse.
Original commit message from CVS:
Converted the mpeg2 encoder asm to gnu asm, removing the dependency of nasm
Added cpu detection in the mpeg2 encoder
removed the inlined mmx asembler to seperate files.
Original commit message from CVS:
More work porting to PPC.
libs/winloader is disabled on PPC - I doubt this can be made to work.
libs/videoscale and libs/idct are also disabled - they should be fixable
though.
Sorted out most of the plugins - avi is disabled for now on PPC;
can be worked on later if there's any chance of getting it to work.
Also provide an automake conditional for compiling vorbis, based on a
configure test for the needed libraries: currently the test isn't
implemented and defaults to "no" so you'll have to fiddle it to compile
vorbis. I shall get hold of vorbis and implement an appropriate test some
other time (if noone else beats me to it).
Original commit message from CVS:
Added a quick hack to allow loop based elements to finish intead of
looping till infinity.
Added compile time i386 or plain C getbits implementation selection.
The vorbis decoder now is our first loop based element!
Original commit message from CVS:
Begun to add support for non i386 architectures, with the help of Chris
Emerson. Added bits to configure to figure out architecture, and added
some alternatives for PPC. Should cause no problems on i386, but I'll
check after this commit, but doesn't yet work on PPC by a fair way...

binaries.zip from http://divx.euro.ru/binaries.zip into the win32
directory **of the source tree**.
Extended and bugfixed thr riff parser to support DivX ;-)
Extended the avi parser to support DivX ;-) and MPEG Layer 3.

the system_encoder can now do video only system streams
sanitized the colorspace and scaler api.
added fast self modifying asm scaler.
worked on the typefind stuff.
added a cool media player (gstplay) it uses the typefinder to playback
avi, mpeg1 (system and video) streams. It is also a testbed and a real app.
Original commit message from CVS:
Added SCR and mux_rate calculations in the MPEG1 multiplexer.
worked toward a unified putbits implementation
Added an MPEG audio layer 1&2 encoder.
Original commit message from CVS:
Reworked the audio resampler.
Added first frames skipping to the mp3 and ac3 parser (this allows you to
skip a number of frames before pushing them).
Removed wrong mmx code from the encoder.
Added Macroblocks per slice to the encoder.
added bilinear and bicubic interpolation to the videoscaler.
Added a MPEG1 multiplexer (no SCR or mux rate calculations yet)

Fixed the mpeg2 encoder. Added MMX optimisations for motion estimation.
Added another mpeg1 encoder.
Added Two filters: smooth and median (a median cut filter)
Made the queue pull buffers.
Original commit message from CVS:
A simple video scaler as a library and an Element. Also a little non
working mpeg2 to mpeg1 converter (still struggling with the quantisation).
Original commit message from CVS:
More changes to the mpeg parser and encoder.
It seems like the mpeg2 decoder does not like some MPEG1 videos. Use
mpeg_play for now (eg. AlienSong)
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.
