Original commit message from CVS:
many changes including:
- now the rate needs to be set explicitly, instead of from a pad
- asynchronous mode has been implemented - and it even works
- some refactoring of the process code
- a plugin api change, GST_DPMAN_PREPROCESS and GST_DPMAN_PROCESS have changed a bit
they are now *a lot* simpler to use, more flexible, and optimised so that the process func is never called if nothing changes - all in all worth the api breakage.
UPDATE YOUR PLUGINS PEOPLE!
Original commit message from CVS:
completely rewrite interpolation so that it is more stable, faster, easier to maintain and it now sounds damned smoooth
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:
New bytestream fileio style api has landed, along with some minor fixes:
- implement gst_bytestream_tell
- prevent buffers from being gobbled after a seek
Original commit message from CVS:
Added gst_bytestream_get_timestamp() call to get timestamp of data at
the front of the stream. If no data in stream, loads 1 byte to get a
new buffer and uses its timestamp.
Does nothing to handle readers that try to read data lengths that span
buffers with multiple timestamps.
_get_timestamp() now used when creating new buffers.
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:
a few internal changes:
- put last_update_timestamp into GstDParam
- added a GstDParamUpdateInfo enum to the update function so that dparams know what context they are updating in (for example, the first update since the pipeline was started)
- rewrote bogus next_timestamp calculation in GstDParamSmooth
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 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.
