GitLab

  (expect some breakage).
* modules/video_filter/blend.c: new alpha-blending module.

When you want to use OSD, you have to register an OSD channel, by calling
vout_RegisterOSDChannel, then pass it to vout_CreateSubPicture.
There is a particular channel, DEFAULT_CHANNEL that can be used for
general purpose.
See modules/control/hotkeys.c for an example.

* added i_channel and i_content properties to subpicture_t
* p_last_osd_message is no more used

An OSD channel can contain simultaneously an OSD text and an OSD widget.

* src/video_output/video_widgets.c: Added OSD sliders when changing volume or position with hotkeys.
Those sliders are graphical (ie not written with characters) and we can now add others OSD "widgets".

* added a lock when changing p_vout->p_last_osd_message

The last OSD message is now deleted before printing new one.

documentation does not include information on which headers each file
includes, since this information isn't correct.

Clarified and doxygenized some of the documentation on subpictures

    with a couple of modules.

* src/video_output/vout_subpictures.c: fixed a few race conditions that
   were triggered by the dvdplay plugin.

  * ./modules/*: fixed a bunch of modules so that they compile under WinCE,
    we now have access_file and the mpeg demux and video decoder working
    (http://zoy.org/~sam/vlc/pocketvlc2.png).

    work is still needed for missing functions. I only touched libvlc for
    the moment, plugins will come in a long long while.
  * ./bootstrap: moved MSVC project files generation here; use --update-msvc.

  * ./modules/codec/spudec/parse.c: implemented subtitle cropping and
    temporarily disabled subtitle cropping.
  * ./modules/codec/spudec/render.c: split RenderSPU into chroma-specific
    functions.

    palette, implemented the "force display" command as forever-living
    subtitles, and reworked some code.
  * ./src/video_output/video_output.c: we increment the image date even if
    we are repeating the previous image, so that subtitles have a chance to
    get displayed.
  * ./src/video_output/vout_subpictures.c: ephemer subpictures don't timeout.

   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.

  * ./include/video.h: moved vout_CopyPicture out of the way, an inline
    function did not make sense here.
  * ./include/video.h: moved vout_ChromaCmp out of the way.
  * ./plugins/avi/fourcc.h, ./include/video.h: merged these two files into
    video.h.
  * ./include/os_specific.h: this file is now always included.
  * ./include/debug.h: removed this file which was almost useless, and moved
    ASSERT to common.h.
  * ./include/common.h: fixed vlc_memalign and changed its prototype to
    follow posix_memalign's.

* introduced a memalign wrapper that will align the memory manually if
  memalign doesn't exist.

  void *vlc_memalign( size_t align, size_t size, void **pp_orig )
  where the return value is the aligned pointer and *pp_orig is the pointer
  that has to be freed afterwards.

  the arithmetic I'm doing on the pointer to align it is not portable to
  64bits architectures. If someone knows how to something portable, please
  tell me ( and no I don't want to do if(sizeof(void *) == blabla) ).

  Other little problem, I was planning to use posix_memalign by default in
  the wrapper implementation but it doesn't work (someone can tell me what
  I'm doing wrong ?)

* re-enabled the sse plugins on win32 as we don't have anymore alignment
  issues.

* fixed typo in vout_directx.c

  * ./Makefile: fixed OS X vlc.app compilation dependencies.
  * ./configure.in: fixed the endianness check under Solaris.

  * ./src/input/input.c: strings are now initialized to "" instead of NULL.

  * ./plugins/spudec/spu_decoder.c: we now properly support the subtitle
    palette information we get from the DVD. Subtitles rox !
  * ./src/video_output/vout_subpictures.c: removed all DVD-specific routines
    and put them into spu_decoder.c.

* New GTK configuration interface. This interface is generated dynamically
  at run-time from the configuration data contained in each plugin.
* config_PutPszVariable and config_GetPszVariable are now thread safe.
* Few modifications/optimizations to the config module.
* Got rid of all the _VAR macros in config.h

This is the first version of the GTK configuration interface. There are still
a few raw corners and a fews things left to do, but it basically does what
I wanted.
Constructive comments like it sucks or it smells rotten fish are of course
very welcome. And if there are GTK gurus out there, please don't hesitate to
add your touch.

I also started to add usefull comments to the configuration options but I'm not
really good at this kind of thing so if people want to help, they can finish
the job. For this look at all the *_LONGTEXT macros at the top of main.c

(PS: Translations will also be appreciated but not right now as the interface
will likely change again in the few coming days)

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 ;-)

   * Got rid of TRACE and intf_DbgMsg which were seldom used anyway.
   * All intf_*Msg functions now write to stderr.
   * Implemented a message queue interface plugins can subscribe to.
   * Wrote the logger interface plugin. Usage:
      vlc -I logger:filename.log
   * Lots of fixes in the SPU renderer.

  * ./plugins/beos/*: BeOS fixes from Rudolf Cornelissen.
  * ./src/interface/main.c: --desync now really accepts a value in ms.
  * ./plugins/vcd/input_vcd.c: fixed a crash when not opening a VCD.
  * ./src/video_output/vout_subpictures.c: fixed subtitles under BeOS and
    other architectures which don't support overlay.

  * ./plugins/win32: skeleton for the win32 interface Ipkiss is developing.
  * ./config.guess ./config.sub: latest GNU versions.
  * ./configure.in: when possible, xvideo is compiled as a plugin.
  * ./vlc.spec: fixed a few minor inaccuracies.
  * ./debian/control: vlc-gui is no longer depended on, but rather recommended.
  * ./src/interface/main.c: --spumargin flag; use this to force displaying
    subtitles at the bottom of the screen instead of putting them in the
    middle, for instance: `--spumargin 5'.

  * ./BUGS: added a list of known bugs. Please add your findings!
  * ./MODULES: added a short description of each module. Maybe we should
    add more details to make this file really useful.
  * ./doc/bugreport-howto.txt: wishful thinking...
  * ./Makefile: added a workaround for the fact that .c files don't depend
    on <videolan/vlc.h>.
  * ./plugins/memcpy/memcpy.c: all memcpy modules are now built from the same
    single file.
  * ./src/interface/main.c: added the --nommx, --no3dnow, --nommxext, --nosse
    and --noaltivec options to vlc.
  * ./configure.in: removed the --disable-mmx option, now useless because
    of the vlc --no* options.
  * ./src/interface/main.c: fixed a crash caused by the memcpy module
    being released too early.
  * ./include/video.h: more vout4 changes, including margin support, more
    FOURCC formats recognized, transparent support of identical or almost
    identical FOURCC formats.
  * ./include/video_output.h: added a vout_Render function to video output
    modules which is to be executed before vout_Display.
  * ./include/common.h: this header is back.
  * ./plugins/chroma/i420_rgb.c: planar YUV 4:2:0 to packed RGB conversion
    functions, mostly taken from vout3's yuv functions, but heavily modified
    to use FAST_MEMCPY and to handle image dimensions which are not multiples
    of 16. Not all functions have been written yet, though.
  * ./plugins/chroma/i420_yuy2.c: planar YUV 4:2:0 to packed YUV conversion
    functions, various targets such as 4:2:2 YUYV, YVYU, UYVY, or 2:1:1 YUYV,
    with accelerated MMX versions.
  * ./plugins/chroma/i422_yuy2.c: same as i420_yuy2.c but takes planar YUV
    4:2:2 pictures in input. With accelerated MMX versions as well. This plugin
    makes it possible to display 4:2:2 files on most video cards without the
    quality loss of 4:2:0 downsampling.
  * ./plugins/filter/*: thanks to the vout_Render function, all filters now
    output their data perfectly in sync.
  * ./plugins/dvdread/Makefile: fix to prevent unnecessary target rebuilds.
  * ./plugins/sdl/vout_sdl.c: support for YV12, UYVY, YUY2 and YVYU overlays.
  * ./plugins/x11/xcommon.c: support for I420, YV12, YUY2 and Y211 overlays.

  * ./ChangeLog: imported the 0.2.92 changes, unrolled current CVS changes.
  * ./include/config.h et al.: this file is no longer generated.
  * ./include/video.h: we use the FOURCC definition of a chroma format to
    describe picture types (see http://www.webartz.com/fourcc/).
  * ./plugins/dvdread/input_dvdread.c: compilation fix by Eyal Lebedinsky.
  * ./plugins/x11/xcommon.c: fixed the XShm operations order.

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.

  * Fixed aspect ratio handling.
  * Fixed potential compilation issues under eg. BSD/OS.

  * 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.
