Original commit message from CVS:
Changes made to the DEBUG system. New header file gstdebug.h holds the
stuff to keep it out of gst.h's hair. DEBUG prints out the process id,
cothread id, source filename and line number. Two new macros DEBUG_ENTER
and DEBUG_LEAVE are used to show the entry and exit of a given function.
This eventually might be used to construct call trace graphs, even taking
cothreads into account. This would be quite useful in visualizing the
scheduling mechanism.
Minor changes to various debug messages.
Also sitting in gstdebug.h is a prototypical DEBUG_ENTER that's capable of
performing DEBUG_LEAVE automatically. It does this by utilizing a
little-known GCC extension that allows one to call a function with the
same parameters as the current function. The macro uses this to basically
call itself. A boolean is used to ensure that when it calls itself it
actually runs the body of the function. In the meantime it prints stuff
out before and after the real function, as well as constructing a
debugging string. This can be used eventually to provide call-wide data
on the DEBUG lines, instead of having to replicate data on each call to
DEBUG. More research is needed into how this would most cleanly be fit
into some other chunk of code, like GStreamer (I think of this DEBUG trick
as a separate project, sorta).
Unfortunately, the aforementioned DEBUG trick interacts quite poorly with
cothreads. Almost any time it's used in a function that has anything
remotely to do with a cothread context (as in, it runs in one), a segfault
results from the __builtin_apply call, which is the heart of the whole
thing. If someone who really knows assembly could analyze the resulting
code to see what's really going on, we might find a way to fix either the
macro or the cothreads (I'm thinking that there's something we missed in
constructing the cothreads themselves) so this works in all cases.
In the meantime, please insert both DEBUG_ENTER and DEBUG_LEAVE in your
functions. Be sure to put DEBUG_ENTER after your variable declarations
and before any functional code, not to put the function name in any DEBUG
strings (it's already there, trust me), and put a DEBUG_LEAVE if you care
enough.
Changes are going to happen in the way DEBUGs and other printouts occur,
so stay tuned.
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:
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:
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:
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:
Added check for vorbis.
Really compile with Xv extension if the library is found.
Changed the disksrc so that is goes to the PAUSE state if eof.
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:
Fix on x86 architectures - was just checking for 386, D'oh.
Fix autogen to run autoheader _before_ autoconf, since it generates a
required file (config.h.in, which I just removed from CVS since its an
autogenerated one). Also fix messed up variables in gst/Makefile.am
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...
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:
libXv is now linked against by test/* and gstplay if it is present.
-lXv isn't leaked all over the place due to AC_CHECK_LIB test.
This is still messy though - we shouldn't have to link explicitly
with extra things just because we use certain plugins.
Build Makefile in tests, but don't recurse into tests when doing the
build (tests no longer in SUBDIRS).
Original commit message from CVS:
Build fixes.
Adapted the test directory to the new state management
added an mpeg2 to avi encoder.
added a v4l to divx capture example.
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:
Added DivX ;-) support by using the wine .dll loader. you must unzip
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.
Fixed a bug in mpg123. Sound still is seriously wrong with layer 3.
Fixed MPEG2 playback in gstplay.
Time indication in gstplay is temporarly broken.

fixed the avi parser (gstriff had wrong size)
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.

Added SCR and mux_rate calculations in the MPEG1 multiplexer.
worked toward a unified putbits implementation
Added an MPEG audio layer 1&2 encoder.

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)

Original commit message from CVS:
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:
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:
Make GDK pixbuf optional, by compiling videosink only if it is present.
Make documentation generated successfully even if libghttp isn't present
(by skipping the ghttpsrc stuff).
Original commit message from CVS:
Added a colorspace library and removed yuv2rgb conversion from the
videosink.
The aviencoder should now more or less work.
Original commit message from CVS:
Added jpeg decoder. the avi decoder now configures the jpeg codec if
an MJPG encoded avi is found. Fixed riff parsing. readded rgb_draw
functions to the videosink. jpeglib is used to decode the jpeg image.
Original commit message from CVS:
Added the riff code into a seperate library in /libs dir. The plugin
loader also checks the /libs path.
The avi parser now uses the riff library.
WAV is broken.
Original commit message from CVS:
Various cleanups. Moved the overlay code to a specialized widget.
One error I cannot seem to fix: switching desktops does not disable the
overlay.
Original commit message from CVS:
Added compiler optimistaion flags to mpg123. reverted to old WRITE_SAMPLE
which was much faster.
Added mpeg_play, the MPEG1 video player. It does not work yet.
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.
Original commit message from CVS:
Fixed lowercase PLUGINS_USE_SRCDIR which made running test apps fail.
Added GHTTP_LIBS to the libraries.
commented out mm_support() call, wich is not working yet and causes errors.
Original commit message from CVS:
Try to compile a little mmx program, set the default value of HAVE_LIBMMX.
some typos fixed. Changed include path for volume.c. RTjpeg uses mmx.h
Original commit message from CVS:
Re- set up the gtk-doc system. I'd managed to mutilate it a while back,
but now it's fixed. I'll put a copy of the HTML output somewhere on the
website tonight.
In order to actually generate the docs, you'll have to install all the
DocBook tools, as well as gtk-doc from GNOME cvs. (see
http://developer.gnome.org/arch/doc/tools.html)
Notes (I'll codify these some day):
- Don't believe the Gnome page, always edit the SOURCES when documenting a
given function, never the tmpl file.
- I'll be re-arranging things a lot, but gtk-doc is smart enough to merge
any changes to the tmpl file. However, gtk-doc's merge and CVS's diff are
two entirely separate animals. We should probably have a virtual mutex on
the entire docs/gst/ directory, over and above what CVS does.
- I'm going to try to end up with a book set (docbook terms), where
docs/gst/ is only one book. There'd be another called docs/manual/, and
another docs/plugins/, etc. If you have any comments as to how these
should be done, gstreamer-devel is the place.
Original commit message from CVS:
Tidy up of configure script.
Make libghttp detection work at all.
Make library configuration specifiable on configure commandline.
Make detection of atomic resource stuff cope with 2.0 linux kernels.
Fix typo (HAVE_ATOMIC_T for HAVE_ATOMIC_H).
Remove generated ltmain.sh file from mp3decode.
Original commit message from CVS:
More incremental updates. I can now successfully produce an rpm simply by
typing `./autogen.sh;make rpm`. This is good ;-)
Original commit message from CVS:
RTjpeg plugin with several elements. It's currently a skeleton, doing no
work at all. Need to have a video display element, some kind of
simulation source (read from .ppm, a la what I do at work to solve the
exact same problem), raw video types, metadata structs, etc.
The RTjpeg.[ch] code is taken from a just-downloaded copy from Justin's
site, with some fixes (#include <asm/types.h> to get __u64,etc). Once the
aforementioned infrastructure is in place, the elements can actually be
set up to do the encode/decode, and we'll have our first functioning video
codec in place. ;-)
Original commit message from CVS:
Changed Makefiles to:
detect xaudio (check header xaudio/decoder.h)
detect mmx.h
detect CSS (check if css.c is in plugins/dvdsrc), need something better.
some LDFLAGS had *.la dependencies which failed for libtool
The build is now 100% on my system.
