Original commit message from CVS:
First pass at an outline for the Filter Writer's Guide. Mostly complete,
though the structure needs some work. Just need someone to write it ;-)
Original commit message from CVS:
Rearranged cothread_switch a bit to move all the code for error conditions
to the end, using goto's to get there. This has the presumed advantage of
consolidating all the normally run code into one chunk, reducing jumps
(and the associated penalties in any modern processor) and limiting cache-
line usage. It may be instructive to look at the generated assembly for
this revision and the previous, to see if gcc is smart enough to do this
for us anyway.
If you want to turn off some of the checks (they are all checks for NULL
pointers, if you're curious) for a speed gain, disable the #define of
COTHREAD_PARANOID at the top.
Original commit message from CVS:
Added code to force the gsttypes plugin to load before gstelements, by
simply having gstelements.c request the plugin. Solves some dependency
problems. This is the correct method of doing this for now, though I had
a thought:
Have a static list of hard dependencies that the plugin system is responsible
for satisfying before even trying to load the plugin. Makes plugin design
easier.
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:
Reworked AC3 decoder. No seeking yet but at least we do not need ac3parse
anymore.
Reworked dvdsrc to read scrambled data (DeCSS not included). I have
modified DeCSS a bit to work in GStreamer. Can I release the code or is
there some lawyer that's going to sue me?
MPEG2 SSE motion compensation.
Tried to add PTS to the MPEG decoder but failed.
Original commit message from CVS:
The bonobo component now works on audio only (mp3/vorbis). Video
is broken because bonobo does not handle multithreading yet.
Added Bonobo toolbar and menu.
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:
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:
Make sure the Gdk thread lock is not held inside the gstreamer pipeline.
Fix the videosink to not hold the Gdk lock when emitting a signal.
All Gtk GUI apps using GStreamer should now handle the Gdk locks when
handling signals from the pipeline (as it should be)
Original commit message from CVS:
Code cleanup, make it adhere to the Gnome/Gtk+ code formatting, which is
quite clean and more readable.
Renamed parseavi to avidecoder
Implemented seeking/time display/pause/play/stop/clean exit to gstmediaplay
Added an element flag to indicate that it cannot deal with noncontigous
buffers. If such an element is found in the pipeline, seeking is disabled
for the complete stream (avidecoder cannot deal with seeking until we convert
it to a loop based element with pull_region to fetch the indeces etc...)
Original commit message from CVS:
Misc fixes and cleanups
A reworked gstplay. Now it is called gstmediaplay. gstplay is a custom
widget that can display media and is to become a bonobo component soon.
put the tables of the mpeg audio encoder in a header file.
maybe faster quantisation for the mpeg encoder.
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:
Manual now gets installed correctly by make install. Problems:
clean / uninstall don't work.
make dist not tested.
pdf manual doesn't have images.
Original commit message from CVS:
Added extra Gtk types for better editor properties (FILENAME, enums)
The disksrcs location property can now be set in the editor: we can
now make our first working mp3 player with gsteditor!!
Original commit message from CVS:
Fixed a severe timestamp bug in mpeg_play.
Create a new thread upon a multisrc element in autoplugging: the autoplug
example now correctly sets up 5 threads for an mpeg player.
Original commit message from CVS:
Added building of the manual to the build system. Currently in a
rudimentary state - will not gracefully give up if tools not available,
will not uninstall / clean, and may not install / make dist properly.
Documentation does not have dependencies on images, so won't rebuild if
they're altered either.
Original commit message from CVS:
Added an autoplug example. This little program (30 relevant lines) is able
to play MPEG1(system)/MPEG2(system)/AVI(DIVX)/Vorbis/AC3 and whatever codec
you write.
Separated the mp3 and mpeg1 types for better reuse.
Original commit message from CVS:
Fixed a bug in the typeloading.
Fixes to various elements so that correct types are returned.
Fixed flag collision with GtkObject.
Elements can now suggest a thread. not sure if this is the right way to
handle automatic thread creation.
Autoplugging now works with multiple sinks and thread setup. No threads
are created for intermediate elements yet, so MPEG may still be choppy.
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:
The cothreads were not initialized in its thread context resulting in
severe stack corruption. This was very hard to track down.
We should be able now to modify some plugins to a loop based setup so that
we can get rid of the mp3parse and mp1videoparse elements.
Modified the GList to a GSList in the queue.
Original commit message from CVS:
A first attempt to fix the queues in a cothreaded pipeline.
Some fixes to the thread handling.
Fix a bug in gstreamer-config : gthread was not included.
gst_bin_create_plan() is now done in the READY state.
a bin with only another bin in it will now work with gst_bin_iterate.
Added some examples for the queues.
