Original commit message from CVS:
Commit my pending changes.
- revert WHERE stuff
- added fast type checking
- add preliminary stack trace functionality
- minor fixes/cleanups.
Original commit message from CVS:
1 Add GST_BUFFER_WHERE support to bytestream.
2 Sort live buffers by timestamp. <g>
3 Rename GST_WHERE macro to GST_WHERE_ARGS.
Original commit message from CVS:
1 Add option GST_BUFFER_WHERE (off by default) to track the file:line
info where each buffer is created. This is useful for tracking
buffer memory leaks.
2 Removed gst_buffer_ref_by_count.
3 Merged the GstBufferCopyFunc fix from HEAD.
Original commit message from CVS:
Sync with my copy before wtay starts hacking...
Decided to keep the GstBuffer name through most code because it's really
messy otherwise, and it doesn't really mean much either way. Saves lots
of stupid casting. fakesrc num_buffers=N ! fakesink ends with a segfault
on EOS right now, not tracked down yet.
Original commit message from CVS:
gstinfo.[ch], cothreads.c: added initial support for -finstrument_functions
gstbin.c: removed a reference to config.h
gstbuffer.[ch]: added gst_buffer_is_span_fast(), used it in gst_buffer_span
elements/gstfilesrc.c: initial work fleshing out the event handling code
everywhere else: wrapped XML stuff in #ifndef's
Original commit message from CVS:
The bufferpool api has changed. Check gstbufferpool.h to see the updated
interface.
Also, the default bufferpool implementation has been finished somewhat. Take a
look at speed.c to see an example of its use, when I get the plugins committed.
Original commit message from CVS:
- changed timestamps to gint64 (*signed* 64-bit)
- updated buf->offset handling to deal with the -1 (0xffffffff) case
- added gst_buffer_span() and gst_buffer_merge (see -devel for details)

Original commit message from CVS:
- commented out remainder of Meta stuff
- enhanced mem_chunk allocation to round up to nearest 32 bytes
this helps ensure that GstBuffers are more likely to be on cache-lines
- added free() and copy() function pointers to GstBuffer
- added code in _destroy and _copy to use above routines if !NULL
- fixed up _copy code to suck less
Original commit message from CVS:
More work on capsnego proxying. It should be OK now.
Added another testcase enum that shows various capsnego algorithms.
Warn about pads that try to set a capability incompatible with their
padtemplate.
Implemented refcounting and copy_on_write for caps/props.
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:
Fixed buffer flag handling
gstplay used old flag handling
updated some plugins for the new objects/error handling
Fixed a serious buffer error in gst_buffer_append
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:
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:
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:
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:
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:
Speedup in mpg123 parsing. speedup in mp1videoparse. rearanged the
MPEG player got rid of some memcpy. bit handling changes.
MMX code for the IDCT and motion compensation in mpeg_play.
Almost as fast as the commercial mpeg player mtv, but with a much
better video quality :-)
