calculated!), but worth a try. Use the following flags:
"--filter invert" for inverse video
"--filter bob" for BOB deinterlacing
* Fixed a potential segfault if the subtitle stream was encountered
before the video stream.
* Misc vout4 fixes.
* Put common_win32.h back into common.h -- it wasn't that big and we
should not multiply header files.
* Added gettext support by Thomas Graf <reeler@reeler.org>, may be
broken on other platforms but we'll only see it when I'm finished
with vout 4 :-)
* Fixed a segfault on exit when no fast_memcpy module was found.
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.
* Added bytes_swap.h to provide ntoh() and htol() on Win32. With this
change we don't have to link winsock2 with every plugin anymore. This
should also give us a slight speed increase.
* Added #define WIN32_LEAN_AND_MEAN in threads.h to speed-up compilation
on Win32.
* Modified ac_downmix_3dn and sse so they compile with the latest gcc for
Win32.
(PS: the dvdread plugin doesn't compile yet on Win32)
Libdvdread files are in extras/libdvdread. They have not been changed from
those of libdvdread 0.9.2. The changes are in the subdirectory videolan.
They basically consist of a new function in the API that does a readv()
instead fo a read().
The library is statically linked with libdvdcss from extras/libdvdcss, and
the whole is statically linked with the plugin dvdread. Dvdread can only be
compiled as a builtin module for the time being, I think (which means I
haven't tried to compile it as a plugin).
Basically, input_dvdread.c is a copy and paste from input_dvd.c with a few
changes to use libdvdread calls. It is still in very alpha stage, but it
should offer the same features as the current DVD input.
It can be called with either the syntax: "dvdread:/dev/dvd"
or "--input dvdread /dev/dvd". The command line switches (-t, -T, -c, -u)
should work too.
* New configure option --with-tuning=[arch], extending --enable-pentiumpro ;
for Pentium, use --with-tuning=pentium, for PowerPC 604 use --with-tuning=604,
and so on.
* Removed --enable-stats configuration directive. Stats are now activated
at runtime with --stats ;
* New intf_StatMsg() call ;
* Vout picture heap is now 8 pictures instead of 5 (better synchro) ;
* Tremendous enhancements in statistics display ;
* Better capabilities handling.
* Activated -D_FILE_OFFSET_BITS=64 -D__USE_UNIX98 on all platforms, fixes
issues under Solaris and QNX.
* Additional checks for SSE-specific (non-MMXEXT) instructions, as
reported in <20010817114220.A23480@slartibartfast.angrypacket.com>.
extras/BSDI_dvdioctl after he suggested it. License is GPL.
* ./configure now checks for an installed libdvd under BSD/OS and
falls back to ours if not found.
* Fixed harmless typos in yesterday's Solaris libdvd patches.
* Bumped libdvdcss version number up to 0.0.3 ; release will probably
follow once the BSDI changes have been tested.
* Various debian scripts fixes.
* Added -lmsvcrt40 to the win32 flags for proper execution under Wine.
* Fixed broken soname setting under Solaris (and OS X, sort of).
* Made the illegal instruction report more explicit.
* BSD/OS 4.3beta1 fixes by Steven M. Schultz <sms@TO.GD-ES.COM>.
libdvdcss. It will try to dlopen() libdvdcss at runtime, though,
and will use the dummy functions only if it couldn't find a valid
libdvdcss. This is probably only useful to package maintainers.
* Tidied the snapshot-* Makefile rules.
* Tidied the modules Makefiles.
* Removed useless stuff in the debian/ directory.
* Removed the "make all" kludge in the Makefile.opts rule. I hope this
patch is harmless on all systems.
evil, but if we don't do it now we'll have to do it when more people
are using it.
* Fixed minor libdvdcss stuff such as the soname and compilation flags.
* New --with-dvdcss flag.
Explanation:
o default: build libdvdcss, statically link vlc against it.
o --with-dvdcss=no: build libdvdcss, dynamically link vlc against it.
o --with-dvdcss=yes: don't build libdvdcss, use already installed one.
o --with-dvdcss=/foo: don't build libdvdcss, use libdvdcss from /foo/*.
(this looks a bit strange to me, I'll find better flag settings)
vlc's DVD input (looks like decoders are expecting data too early and
DVD input can't cope with it due to decryption). Needs to be investigated.
* Plugins are now compiled in plugins/* and libraries in lib/*.
* The KDE UI compiles again but does not work yet.
* ALSA plugin message corrections.
* Calculation modules can now be calledwith a shorter name
(eg. '--downmix mmx' instead of '--downmix downmixmmx').
* Fixed insane verbosity of the SDL plugin.
- defined off_t as a long long. This allows DVD navigation to work.
This change is to be implemented on a compiler by compiler basis. For
now, it works on mingw32 (tested) and should work on MSVC (not tested).
- Implemented a quick and dirty hack in intf_msg.c to be able to display
long long integers with printf on Win32. This change is also necessary
to avoid segfaults when debug is enabled in vlc on Win32.
- few minor changes in the directx plugins.
- defined snprintf in common.h and removed a few #ifdef WIN32
and stderr to the specified file. This option should mainly be useful
on Win32.
- On Win32, vlc now has an icon associated to the .exe file, and is a full
GUI application (you don't have this annoying dos command box anymore)
- Added INSTALL-win32.txt for specific details to the Win32 port.
I've tested these changes on Win32 and Linux, let's hope I didn't break
vlc for other platforms.

It works at last! configure with --enable-profiling, build, run
vlc (you may want to add --noaudio, it currently segfaults with sound
here) and launch "gprof vlc" when finished.
To make gprof work with multithreaded programs, one needs to set the
internal ITIMER_PROF timer for each new thread launched. I did this
through a wrapper in vlc_thread_create (see include/threads.h).
* Merged dvdcss_init and dvdcss_open into dvdcss_open, and dvdcss_close
and dvdcss_end into dvdcss_close. libdvdcss API now has 7 functions.
* Another failed attempt at profiling vlc under Linux: ported the
threads API to GNU Pth. Activate with --enable-pth. It doesn't seem to
spawn new threads for me, maybe someone will have better luck.
* Makefile optimizations.
* Automatic build of libdvdcss if not found.
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"...
Notes: o I called it 'directx' instead of 'windx' because it
made a lot more sense to me.
o Completely untested. I didn't manage to compile it yet.
o Code in vout_directx.c will go through a big rewrite when
vout 4 is finished. Xav is already working on this.
* 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.
* aout and vout are now allocated in banks, making it possible to have
several of them at the same time.
* configure now checks for MMX and MMX EXT support in the assembler.
* Removed all MMX code from the main program and moved it to the
existing idct modules (Closes: Debian bug #96036).
Don't forget to make distclean before building vlc again.
fix: the output threads are now spawned when a decoder needs one,
so it can decide the audio frequency or the video window size. Still
under heavy construction, so don't get too excited at finding bugs
in it yet.
Note: this change broke the XVideo module, so I made its score much
lower than before. I suspect xvideo.so had a bug before which only
appears now. Other video output plugins may be broken as well, but
again this might be due to old existing bugs showing their ugly head.
* Fixed a few buffer overflows in the Gnome interface.
* The module bank is now a global variable. The video output bank and
the audio output bank might follow (when they exist).
* Coding style and organization fixes to the spdif decoder.
* autoconf and Makefile changes by Arnaud Gomes-do-Vale
<arnaud@carrosse.frmug.org>.
* Miscellaneous QNX compile fixes.
* Beginning of the mingw32 port by Gildas Bazin <gbazin@netcourrier.com>.
* Added Marcari and Gildas to the AUTHORS file.
(I commited the mingw32 port because it doesn't add any new code outside
the #ifdefs, but we won't tell a word about it for the moment. We don't
really need windows users whining about bugs, do we ?)
* Built-in modules support almost finished.
Now you can compile any module within vlc, even the Gnome, Qt, SDL
and GGI modules at the same time, resulting in an awful extra fat
vlc binary with gazillons of library dependecies.
The only exception is that the Gnome and Gtk+ modules can't be
compiled together into vlc. But you can have one compiled built-in
and the other as a plugin.
Another consequence is that libdl should no longer be needed under
MacOS X. I'll check this as soon as possible.
A few words about the changes:
- heavy Makefile butchery has taken place, each plugin now has its own
Makefile. I know recursive make blablah harmful, but it was just so
much easier to do this way.
- Makefile.in has disappeared, we now generate Makefile.opts with
the overall configuration options, and Makefile.modules which is
specific to module compilation.
- After ./configure has been run you may want to modify Makefile.opts
to check which modules will be compiled built-in or as plugins.
- Some modules cannot be compiled built-in right now because proper
linkage doesn't work yet. We don't really care since they're the
interface or video output modules. The most important stuff works
(iDCT, motion, YUV, input).
- It's perfectly valid to compile a module both as built-in and as a
plugin. vlc will only load the built-in one, but I'll add an option
to ignore built-in modules for testing purposes.
- We *should* see a performance increase here. I didn't have much time
to test it, but if anyone can confirm and perhaps give a rough
estimate of how much we gain...
