It is possible, that some minor piece of code was badly tracked, for
some reasons (SVN, mainly) or that some small developers did not answer.
However, as an "œuvre collective", defined as in "CPI 113-2 alinéa 3",
and seeing "Cour. Cass. 17 Mai 1978", and seeing that the editor and
the very vast majority of developers have agreed (> 99.99% of the code,
> 99% of developers), we are fine here.

This try to avoid vlc_object_find() as much as possible.
This is conservative, because where there is no associated parent input, we'll try to find in certain cases the parent input. This will probably be
 removed later on. Because yes, there is not necessarily a parent input for access and demux, especially if created from stream_UrlNew().

The GUI need to be updated (QT4/macosx/wx).
The module "dump" and "bandwidth" need to be ported to stream_filter.

Missing some cases that I could not test.
Also ffmpeg/chroma.c is locked, so I can but leave it broken.
Fix is for the remaining modules is obvious and the issue is easy to detect.

(da big courmischage)

  * ./modules/misc/testsuite/*: moved the null module into three test modules
    that are only built when --enable-testsuite is activated. This directory
    can be a good place for compilation tests or performance benchmarks.

    gtk_main() in its own thread, and does nothing on subsequent calls. This
    ensures that gtk_main is only running once.
  * ./modules/gui/familiar/*, modules/gui/gtk/*: the familiar, gtk and gnome
    modules are now fully reentrant thanks to their use of the gtk_main module.
  * ./src/libvlc.c: implemented vlc_set(), a wrapper for config_Put* available
    to external programs.
  * ./src/libvlc.c: removed vlc_stop() and vlc_end(), everything is now done
    by vlc_destroy().
  * ./modules/control/rc/rc.c: implemented a few new functions. For instance,
    run "vlc -I rc" and then type "intf gtk" or "intf gnome". You can even
    launch several of them. "segfault" works, too.

    waveout, directx, qnx, beos, win32, macosx, and the AltiVec modules.
  * ALL: removed mention of AC3 in favour of A52.
  * ./configure.in, ./Makefile*: modules can now be built deeper than 1
    directory. As a consequence, the build is even slower (but I'm fixing
    this) and make clean doesn't work anymore.

    about 2000 lines of code.

    I could not test everything on every architecture, so please report
    any module breakage (especially on BeOS, OSX and QNX).

   As for video output 4, this breaks almost everything, but I'll slowly
  do what remains to be fixed during the weekend.

   Changes in vlc:
   ===============

  * vlc is now a very small program (20 lines) which uses the libvlc API;
   it is quite simple for the moment but can be extended in the future.

  * interfaces, decoders, video outputs, etc. are now almost the same
   objects (yes, I know, this is C++ redone in C) and are structured in
   a tree. More about this later, but basically it allows the following
   nice features:
    - several interfaces
    - several playlists with several outputs
    - input plugins spawning helper interfaces (will be used for DVD menus)
    - anything spawning anything; I swear there are useful uses for this!

  * libvlc can be used in other programs; I'm currently writing a Mozilla
   plugin for my employer.

   Things currently broken:
   ========================

  * most interfaces, most ports
  * the playlist handling (almost finished rewriting this though). This means
   no file can be played from the GUI, you need to use the commandline. This
   also means it segfaults at EOF, when exiting the program, and it sometimes
   refuses to open a file when asked to.

  * ALL: internationalized all configuration strings.
  * ./src/interface/main.c: we now set LC_CTYPE to get the right charset.
  * ./src/misc/configuration.c: lots of simplifications in the code.
  * ./po/vlc/pot: updated translations.

This is the first part of the new configuration architecture for vlc.
Two other parts will follow soon:
- config file implementation
- gtk configuration interface.

This part won't change much for end-users as these changes are mostly
internal, you will however notice that the command line interface has
changed. It will maybe be less user-friendly as I almost removed the
short options but it shouldn't a big problem when the config file is
implemented.

What as changed is that it is really easy now to add configuration
options to vlc. Plugins can also implement configuration options. All
you have to do is to declare a MODULE_CONFIG section in your plugin.
If you want to know more about this look at configuration.h and for some
example: main.c, dsp.c or xvideo.c

It would be nice if every developper could now start using configuration
options in there plugins and also enhance old plugins.

That's it, now let's hope I didn't break too many things ;-)

Some heavy changes today:
  * Removed duplicate function checks from configure.in.
  * Added extra magic to Makefile.modules so that the module Makefiles
    are now ridiculously simple. And I mean *simple*. Check it! This will
    make a possible switch to full autoconf/automake a lot easier.
  * Added the vlc version name to the plugin symbols, to be sure we only load
    plugins with the same version number. A nasty consequence is that you
    need to rebuild your tree after midnight if you are using a CVS tree :-)
  * Got rid of modules_export.h by #defining exported functions in the same
    header as their prototype.
  * Added modules_inner.h and other commonly used .h files to common.h so
    there are less and less files to include, and renamed common.h to
    <videolan/vlc.h>.
  * First modifications to the module handling system towards my ultimate
    goal to get rid of the *_Probe functions. Got rid of TestMethod and
    TestCPU, as well as src/misc/tests.c.
  * Wrote the chroma plugin handling functions. No YUV functions have been
    ported yet because it'ls a lot of work, but the core system works, I
    tried it with a naive yv12->rgb16 plugin (which will disappear when the
    real functions are ready).
  * Made a lot of functions in dvd_summary.c one-liners to avoid wasting
    too many output lines.
  * Fixed a segfault in input_dvd.c:DVDInit.
  * Added a fixfiles.sh script in plugins/gtk to be run after Glade has
    generated its C files.
  * Did some work on the KDE interface to make it suck a bit less. It still
    segfaults, but at least it runs and it looks less ugly.
  * RGB SDL rendering works again, though in 16bpp only.
  * Made plugins/vcd/linux_cdrom_tools.c independent of any vlc structure
    so that it'll be easily put in a library. Maybe libdvdcss?
  * Fixed VCD date display.
  * Merged vout_xvideo.c, vout_x11.c and vout_common.c into xcommon.c.
  * Wrote non-Shm XVideo output.
  * Made X11 output work again. Still pretty unstable, only works for 16bpp.
  * Additional french translation in po/fr.po. Any taker for the rest?
  * Fixed a segfault in video_output.c when the allocated pictures were
    not direct buffers.
  * If $DISPLAY isn't set, don't try to run the Gtk+ interface.
  * Replaced 48x48 .xpm images with 32x32 ones to conform to Debian policy
    (Closes Debian bug #126939).
  * Removed the automatic ./configure launch when running `make all' for
    the first time.

Stuff currently more broken than it ought to be:
  * The wall filter. Being fixed.
  * x11 and sdl plugins for depth != 16bpp.
  * Software YUV.
  * gvlc, gnome-vlc, kvlc shortcuts. Use --intf instead for the moment.

  * COMPLETE CVS BREAKAGE !! The MAIN branch is going to be a playground
    for my nevrotic and destructive pulsions during the next few hours!

  * If you want to test vlc, please use the v0_2_92_branch branch.

  * Stuff currently working:
     - direct to YUV buffer decoding
     - non-ugly subtitle blending
     - XVideo and SDL video output

  * Stuff currently utterly broken:
     - aspect ratio
     - software rendering (ie, all other video output plugins)

  * Additional misc changes:
     - Renamed spu_dec to spudec and mad_adec to mad to stay coherent with
       other plugins. Also, renamed mpeg to mpeg_system.
     - Added jobi to the AUTHORS file.
     - Factored code common to vout_x11.c and vout_xvideo.c.

now be included *before* threads.h ;
* Changed all files to include intf_msg.h before threads.h ; while I was
at it, I update the copyright notices ;
* Removed the obsolete darwin plug-in.

  * Put most builtins in plugins again due to performances issues (more
    about this in a forthcoming post here).
  * Fixed the painfully slow build process (at last!).
  * Moved the null plugin together with the dummy one.
  * Added new dummy input plugin.

   More on the dummy input plugin: we'll use it to insert commands in
  the playlist. Currently implemented are the "quit" and "pause" functions,
  here are examples on how they are used:

    vlc file.mpeg vlc:quit                # exit after file.mpeg has been read.

    vlc file1.mpeg vlc:pause:3 file2.mpeg # pause 3 seconds before playing
                                          # the next file.

   From now we can more efficiently benchmark vlc. For instance, to test
  the video output changes I am doing, I use such a command:

    time vlc -I dummy --noaudio file.mpeg vlc:quit

   Future extentions might include more interesting stuff like "switch
  to full screen", "repeat next file 3 times", "switch to SDL video
  output"...

  * Various little fixes
   - BeOS interface compilation fix by Rene Gollent.
   - DirectX plugin compilation fix by Gildas Bazin.
   - removed %ebx spill in the iMDCT plugins.

  * Fixed the BeOS compile typo.
  * The ALSA plugin is back.
  * A gift for Gildas: plugins don't rely on backlinking any more. The
    drawback is the dirty magic in include/modules_export.h which has to
    be included whenever a module needs one of the functions in it. But
     a) we should less and less rely on those functions
     b) no plugin code modification was needed

   The BeOS and MacOS X modules may be broken when compiled as plugins,
   I'll check this later when I can reboot under BeOS.

  * Header cleaning: filled all empty authors fields, added CVS $Id stuff.
  * Fixes to aout_darwin.c by Colin Delacroix <colin@zoy.org>.
  * Fixes to configure.in, Makefile.in and main.c (Altivec detection)
    by Eugenio Jarosiewicz <ej0@cise.ufl.edu>.
  * Added Colin and Eugenio to the AUTHORS file.

  * Ported Glide and MGA plugins to the new module API. MGA never worked,
    so this didn't make it work better.
  * Started thinking about built-in modules, and added some code to
    make it easier eventually.
  * Added Oct in the AUTHORS file.
  * Fixed a mistake in configure.in.
  * All your base are belong to us.
  * Fixed a bug in src/misc/modules which prevented loading modules
    when launched from the Tracker.
  * Fixed a similar bug in src/video_output/video_text.c.
  * BeOS CSS support, thanks to Markus Kuespert <ltlBeBoy@beosmail.com>
    who ported the Linux DVD ioctls. We can now read encrypted DVDs
    under BeOS ! Woohoo.

   duplication
 . YUV transformations now use the new module API ; now only the vout
   and interface still depend on the old plugin API
 . changed TestMMX to TestCPU because we will be able to test for other
   specific extensions (3DNow, SSE) for the forthcoming IDCT we'll
   borrow to mpeg2dec (as usual :P)
 . don't show "hiding module" messages anymore except in debug mode
 . swapped C IDCT and Classic IDCT scores since the classic one seems
   to be faster ; anyway you should use the MMX one
 . fixed a Makefile bug under BeOS
 . tried to fix the cpuid code so that it compiles under BeOS (Polux, can
   you test it when you have time ?)

 . complete commenting of modules_core.h and small modifications
 . separated MODULE_CONFIG_START and ADD_WINDOW (Henri, beware)
 . fixed a very, very old bug that caused namespace collision between
   plugins (Henri, beware: call your aout_getplugin function like this,
   not alsa_aout_getplugin)
 . removed the Debian specific clean rules from the Makefile, since they
   are already handled by the debian/rules script.
 . tidied a few compilation rules (-lfoo should always be at the end)

 . made the audio_output API a bit simpler.

 . got rid of modules_config.h.

 . fixed `make install' rule.

 . fixed warnings in the MMX YUV compilation.

 . probably fixed a bug in the input : pp_foo structures were free()d at
   the end, but this was useless since the last call to realloc() is
   equivalent to free(), and two consecutive calls to free() aren't a
   goo idea.

 . we check that the version number match and that we don't already have
   a module by that name when loading a new module.

 . all public module_* functions now properly lock the module bank.

 . the audio_output now uses the new module API ; EsounD and DSP modules
   have been ported, which should be enough for Henri to port the ALSA one.


   The new plugin API is now much simpler ; it's now just a matter of
calling module_Need( p_main->p_module_bank, MODULE_CAPABILITY_FOO, p_data );
and if successful we get the best module. Capabilities can be ORed, so that
one can ask for a plugin that does VOUT _and_ INTF actions for instance.

   It's not complete yet though -- by making it generic I had to do a few
ugly casts here and there, which I am going to fix ASAP. Also, command line
selection of a plugin does not work yet.

   The switch to the new plugin API has probably broken the BeOS audio
output ; we can either wait until the whole vlc has switched to the new
plugins, or create a separate beos_sound.so that conforms to the new API.

 . added the Null Module, the module that does nothing but that is going
    to be of great help for debugging my module code.
