Vangloria: Added blurb about making self-contained packages

== Introduction ==

MSYS is a helper environment for MinGW, the compiler chain for Windows based on GCC. It is the fastest way to build VLC natively on Windows.

This howto was re-created by [[User:J-b|Jean-Baptiste Kempf]] and updated in June 2009.

== Install MinGW ==

Use the main installer 5.1.4 found at
http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/MinGW%205.1.4/MinGW-5.1.4.exe/download

Go through the wizard, selecting "Downloading and Install" and using the candidate release. Select gcc, g++ and MinGW make. It should download automatically:
*mingwrt-3.15
*w32api-3.12
*binutils-2.18
*gcc-core-3.4.5
*gcc-g++-3.4.5
*mingw32-make-3.81

== Install MSYS ==

* Install 7-zip and Mozilla Firefox
* Install MSys 1.0.11-rc1 with the exe: http://sourceforge.net/project/downloading.php?group_id=2435&filename=MSYS-1.0.11.exe
Accept Post Install: [y]
MinGW Installed? : [y]
path to MinGW: [c:/MinGW]
* Install MSys Developer Tooltkit: http://downloads.sourceforge.net/mingw/msysDTK-1.0.1.exe

=== AutoTools ===

Update your autoconf, automake and libtool by downloading and installing them, keeping in mind that you need to extract the content of the usr folder in C:\Msys
* http://sourceforge.net/projects/mingw/files/MSYS%20autoconf/autoconf-2.63-1/autoconf-2.63-1-msys-1.0.11-bin.tar.lzma/download
* http://sourceforge.net/projects/mingw/files/MSYS%20automake/automake-1.11-1/automake-1.11-1-msys-1.0.11-bin.tar.lzma/download
* http://sourceforge.net/projects/mingw/files/MSYS%20libtool/libtool-2.2.7a-1/libtool-2.2.7a-1-msys-1.0.11-bin.tar.lzma/download

You can also compile them according to:
* http://wiki.enlightenment.org/index.php/EFL_Windows_XP
* http://www.mingw.org/wiki/msys

== Install other tools ==

http://prdownloads.sourceforge.net/mingw/libcrypt-1.1_1-2-msys-1.0.11-dll-0.tar.lzma

Installing mingw-utils is recommended: http://prdownloads.sourceforge.net/mingw/mingw-utils-0.3.tar.gz, extract it to mingw/bin.

Installation of wget too: http://prdownloads.sourceforge.net/mingw/wget-1.9.1-mingwPORT.tar.bz2

Although this is a mingwPORT package it already has a precompiled wget on board.
Extract the .tar.bz2 file. It contains wget.exe in the bin subfolder, extract it to mingw/bin.

=== Install Git and checkout VLC ===

See [[Git_Windows]].

You can also retrieve the source code from [http://www.videolan.org/vlc/download-sources.html VideoLAN Project: VLC media player source code]

=== PKG-CONFIG ===

pkg-config is a mess, this is not NEWS... And you cannot compile it from Windows because of a few bugs...

Get Glib from GNOME: http://ftp.gnome.org/pub/GNOME/binaries/win32/glib/2.18/glib_2.18.2-1_win32.zip
Unzip it to C:\Msys.

Get PKG-CONFIG from GNOME: http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/pkg-config-0.23-2.zip
Unzip it to C:\Msys.

== Contribs ==

Take the precompiled contribs from:
http://people.videolan.org/~jb/Contribs/

Copy them in your ~
tar xvjf contrib-20090813-win32-bin-gcc-4.2.1-sjlj-runtime-3.15.2-only.tar.bz2 -C /
rm -v /usr/win32/bin/moc /usr/win32/bin/uic /usr/win32/bin/rcc

== Bootstrap VLC ==

cp -v /usr/win32/share/aclocal/* m4/
cp -v /usr/share/aclocal/* m4/
PATH=/usr/win32/bin:$PATH ./bootstrap
It should warn about gettext... Just ignore.

== Configure ==

sh extras/package/win32/configure-msys.sh
* If you downloaded a VLC source code tarball, retrieve ''configure-msys.sh'' and ''configure-common.sh'' from [[http://git.videolan.org/?p=vlc.git;a=summary vlc.git]] / extras / package / win32 /

== Compile ==

PATH=/usr/win32/bin:$PATH make
If you have Cygwin and others tools installed, try using a shorter PATH inside MSYS shell i.e.
$ echo $PATH
.:/usr/local/bin:/mingw/bin:/bin

==Creating self-contained packages==

Once the compilation is done, build self-contained VLC packages with the following "make" commands:

make package-win32-base

(This will create a subdirectory named vlc-x.x.x with all the binaries "stripped" without any debugging symbols).

make package-win32-zip

(Same as above but will package the directory in a zip file).

make package-win32

(Same as above but will also create an auto-installer package. You will need to have NSIS installed in its default location for this to work).

* If you have permissions problems running make package-*, chmod 777 -R the vlc folder.
* If you have permissions problems running vlc.exe after packaging, rename or delete vlc.exe.manifest

== Random bootstrap, configure, and make errors ==

There have been reports of random msys errors during bootstrap, configure, and make. They usually don't repeat themselves between runs. Rule out that your mingw-msys installation is at fault by building in windows safe mode. Even if this works, it may then be more practical to try a cross-compilation build.

Vangloria:

{{Module|name=bluescreen|type=Video filter|first_version=0.9.0|description=change the video's alpha channel}}

This filter can be used in the mosaic framework to set a video's alpha channel (or transparency) based on a pixel's color. This is also known as green screen or chroma key blending and can be used to create effects like on most weather channels.

== Options ==
{{Option
|name=bluescreen-u
|value=integer
|default=120
|description=U chroma component (0 to 255)
}}

{{Option
|name=bluescreen-v
|value=integer
|default=90
|description=V chroma component (0 to 255)
}}

{{Option
|name=bluescreen-ut
|value=integer
|default=17
|description=U chroma component threshold (0 to 255)
}}

{{Option
|name=bluescreen-vt
|value=integer
|default=17
|description=V chroma component threshold (0 to 255)
}}

== Example ==
% '''vlc -vvv --vlm-conf mosaic.vlm --mosaic-keep-picture --sub-filter mosaic'''

And the vlm config:

new channel0 broadcast enabled
setup channel0 input rushfondvert.avi
setup channel0 output #duplicate{dst=mosaic-bridge{chroma=YUVA,vfilter=bluescreen},select=video}

new background broadcast enabled
setup background input redefined-nintendo.mpg
control background play

control channel0 play

Have a look at http://people.videolan.org/~dionoea/bluescreen2.mpg for an example of the VLC bluescreen filter. The overlay video is http://people.videolan.org/~dionoea/rushfondvert.avi and features someone with a mask in front of a green background. The bluescreen module's default values are adjusted to remove the background from this video. For other videos you should use your favorite color editing tool to find out the appropriate U and V values.

There have been reports of random msys errors during bootstrap, configure, and make. You can tell they are random errors because they usually don't repeat themselves between runs. Try disabling antivirus. If this doesn't work, rule out that your mingw-msys installation is at fault by building in windows safe mode, or in a (gasp) FAT32 filesystem. Even if this works, it may then be more practical to try a cygwin or cross-compilation build.

== Introduction ==

MSYS is a helper environment for MinGW, the compiler chain for Windows based on GCC. It is the fastest way to build VLC natively on Windows.

This howto was re-created by [[User:J-b|Jean-Baptiste Kempf]] and updated in June 2009.

== Install MinGW ==

Use the main installer 5.1.4 found at
http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/MinGW%205.1.4/MinGW-5.1.4.exe/download

Go through the wizard, selecting "Downloading and Install" and using the candidate release. Select gcc, g++ and MinGW make. It should download automatically:
*mingwrt-3.15
*w32api-3.12
*binutils-2.18
*gcc-core-3.4.5
*gcc-g++-3.4.5
*mingw32-make-3.81

== Install MSYS ==

* Install 7-zip and Mozilla Firefox
* Install MSys 1.0.11-rc1 with the exe: http://sourceforge.net/project/downloading.php?group_id=2435&filename=MSYS-1.0.11.exe

MinGW Installed? : [y]
path to MinGW: [c:/MinGW]
* Install MSys Developer Tooltkit: http://downloads.sourceforge.net/mingw/msysDTK-1.0.1.exe

=== AutoTools ===

Update your autoconf, automake and libtool by downloading and installing them, keeping in mind that you need to extract the content of the usr folder in C:\Msys
* http://sourceforge.net/projects/mingw/files/MSYS%20autoconf/autoconf-2.63-1/autoconf-2.63-1-msys-1.0.11-bin.tar.lzma/download
* http://sourceforge.net/projects/mingw/files/MSYS%20automake/automake-1.11-1/automake-1.11-1-msys-1.0.11-bin.tar.lzma/download

You can also compile them according to:
* http://wiki.enlightenment.org/index.php/EFL_Windows_XP
* http://www.mingw.org/wiki/msys

== Install other tools ==

http://prdownloads.sourceforge.net/mingw/libcrypt-1.1_1-2-msys-1.0.11-dll-0.tar.lzma

Installing mingw-utils is recommended: http://prdownloads.sourceforge.net/mingw/mingw-utils-0.3.tar.gz, extract it to mingw/bin.

Installation of wget too: http://prdownloads.sourceforge.net/mingw/wget-1.9.1-mingwPORT.tar.bz2

Although this is a mingwPORT package it already has a precompiled wget on board.
Extract the .tar.bz2 file. It contains wget.exe in the bin subfolder, extract it to mingw/bin.

=== Install Git and checkout VLC ===

See [[Git_Windows]].

You can also retrieve the source code from [http://www.videolan.org/vlc/download-sources.html VideoLAN Project: VLC media player source code]

=== PKG-CONFIG ===

pkg-config is a mess, this is not NEWS... And you cannot compile it from Windows because of a few bugs...

Get Glib from GNOME: http://ftp.gnome.org/pub/GNOME/binaries/win32/glib/2.18/glib_2.18.2-1_win32.zip
Unzip it to C:\Msys.

Get PKG-CONFIG from GNOME: http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/pkg-config-0.23-2.zip
Unzip it to C:\Msys.

== Contribs ==

Take the precompiled contribs from:
http://people.videolan.org/~jb/Contribs/

Copy them in your ~
tar xvjf contrib-20090813-win32-bin-gcc-4.2.1-sjlj-runtime-3.15.2-only.tar.bz2 -C /
rm -v /usr/win32/bin/moc /usr/win32/bin/uic /usr/win32/bin/rcc

== Bootstrap VLC ==

cp -v /usr/win32/share/aclocal/* m4/
cp -v /usr/share/aclocal/* m4/
PATH=/usr/win32/bin:$PATH ./bootstrap
It should warn about gettext... Just ignore.

== Configure ==

sh extras/package/win32/configure-msys.sh
* If you downloaded a VLC source code tarball, retrieve ''configure-msys.sh'' and ''configure-common.sh'' from [[http://git.videolan.org/?p=vlc.git;a=summary vlc.git]] / extras / package / win32 /

== Compile ==

PATH=/usr/win32/bin:$PATH make
If you have Cygwin and others tools installed, try using a shorter PATH inside MSYS shell i.e.
$ echo $PATH
.:/usr/local/bin:/mingw/bin:/bin

== Random bootstrap, configure, and make errors ==

There have been reports of random msys errors during bootstrap, configure, and make. You can tell they are random errors because they usually don't repeat themselves between runs. To rule out that your mingw-msys installation is at fault, try building in windows safe mode, or build in (gasp) a FAT32 filesystem. Even if this works, it may then be more practical to try a cygwin or cross-compilation build.

Hacker Guide/Video Output

2009-06-14T17:46:41Z

Vangloria: Added recommendation to look at vmem.c, directfb.c, svgalib.c.

=The video output layer=

==Data structures and main loop==

Important data structures are defined in include/video.h and include/video_output.h. The main data structure is picture_t, which describes everything a video decoder thread needs. Please refer to this file for more information. Typically, p_data will be a pointer to YUV planar picture.

Note also the subpicture_t structure. In fact the VLC SPU decoder only parses the SPU header, and converts the SPU graphical data to an internal format which can be rendered much faster. So a part of the "real" SPU decoder lies in src/video_output/video_spu.c.

The vout_thread_t structure is much more complex, but you needn't understand everything. Basically the video output thread manages a heap of pictures and subpictures (5 by default). Every picture has a status (displayed, destroyed, empty...) and eventually a presentation time. The main job of the video output is an infinite loop to : [this is subject to change in the near future]

#Find the next picture to display in the heap.
#Find the current subpicture to display.
#Render the picture (if the video output plug-in doesn't support YUV overlay). Rendering will call an optimized YUV plug-in, which will also do the scaling, add subtitles and an optional picture information field.
#Sleep until the specified date.
#Display the picture (plug-in function). For outputs which display RGB data, it is often accomplished with a buffer switching. p_vout->p_buffer is an array of two buffers where the YUV transform takes place, and p_vout->i_buffer_index indicates the currently displayed buffer.
#Manage events.

==Methods used by video decoders==

The video output exports a bunch of functions so that decoders can send their decoded data. The most important function is vout_CreatePicture which allocates the picture buffer to the size indicated by the video decoder. It then just needs to feed (void *) p_picture->p_data with the decoded data, and call vout_DisplayPicture and vout_DatePicture upon necessary.

*picture_t * vout_CreatePicture ( vout_thread_t *p_vout, int i_type, int i_width, int i_height ) : Returns an allocated picture buffer. i_type will be for instance YUV_420_PICTURE, and i_width and i_height are in pixels.

=Warning=

If no picture is available in the heap, vout_CreatePicture will return NULL.

*vout_LinkPicture ( vout_thread_t *p_vout, picture_t *p_pic ) : Increases the refcount of the picture, so that it doesn't get accidently freed while the decoder still needs it. For instance, an I or P picture can still be needed after displaying to decode interleaved B pictures.
*vout_UnlinkPicture ( vout_thread_t *p_vout, picture_t *p_pic ) : Decreases the refcount of the picture. An unlink must be done for every link previously made.
*vout_DatePicture ( vout_thread_t *p_vout, picture_t *p_pic ) : Gives the picture a presentation date. You can start working on a picture before knowing precisely at what time it will be displayed. For instance to date an I or P picture, you must wait until you have decoded all previous B pictures (which are indeed placed after - decoding order != presentation order).
*vout_DisplayPicture ( vout_thread_t *p_vout, picture_t *p_pic ) : Tells the video output that a picture has been completely decoded and is ready to be rendered. It can be called before or after vout_DatePicture.
*vout_DestroyPicture ( vout_thread_t *p_vout, picture_t *p_pic ) : Marks the picture as empty (useful in case of a stream parsing error).
*subpicture_t * vout_CreateSubPicture ( vout_thread_t *p_vout, int i_channel, int i_type ) : Returns an allocated subpicture buffer. i_channel is the ID of the subpicture channel, i_type is DVD_SUBPICTURE or TEXT_SUBPICTURE, i_size is the length in bytes of the packet.
*vout_DisplaySubPicture ( vout_thread_t *p_vout, subpicture_t *p_subpic ) : Tells the video output that a subpicture has been completely decoded. It obsoletes the previous subpicture.
*vout_DestroySubPicture ( vout_thread_t *p_vout, subpicture_t *p_subpic ) : Marks the subpicture as empty.

==How to write a video output plug-in==

A video output takes care of the system calls to display the pictures and manage the output window. For the most minimalistic framework, look at vmem.c, which just "renders" to dummy internal memory. From there, go on to directfb.c and svgalib.c, and finally go for x11 and windows.

Have a look at plugins/x11/vout_x11.c. '''[OUTDATED?]''' You must write the following functions :

#int vout_Probe ( probedata_t *p_data ) : Returns a score between 0 and 999 to indicate whether it can run on the architecture. 999 is the best. p_data is currently unused.
#int vout_Create ( vout_thread_t *p_vout ) : Basically, initializes and opens a new window. Returns TRUE if it failed.
#int vout_Init ( vout_thread_t *p_vout ) : Creates optional picture buffers (for instance ximages or xvimages). Returns TRUE if it failed.
#vout_End ( vout_thread_t *p_vout ) : Frees optional picture buffers.
#vout_Destroy ( vout_thread_t *p_vout ) : Unmaps the window and frees all allocated resources.
#int vout_Manage ( vout_thread_t *p_vout ) : Manages events (including for instance resize events).
#vout_Display ( vout_thread_t *p_vout ) : Displays a previously rendered buffer.
#vout_SetPalette ( vout_thread_t *p_vout, u16 *red, u16 *green, u16 *blue, u16 *transp ) : Sets the 8 bpp palette. red, green and blue are arrays of 256 unsigned shorts.

==How to write a YUV plug-in==

Look at the C source plugins/yuv/transforms_yuv.c. You need to redefine just the same transformations. Basically, it is a matrix multiply operation. Good luck.

Win32CompileCygwinNew

2009-06-14T02:41:23Z

Vangloria: Added a text box for emphasis in libtool modification

This is a new version of the Win32CompileCygwin written by [[User:J-b|Jean-Baptiste Kempf]]
'''This version ONLY works for 0.9.x and for 1.0.x.'''

'''WARNING''': building VLC on Cygwin has ever been a failure-prone task. It is also very slow. You should really consider cross-compiling from Linux (on a virtual machine, via dual-boot or from another computer). You were warned.

=Introduction=

This is a guide for Windows users with a step-by-step instruction to download, install, configure and build your VLC.

This guide uses [http://www.cygwin.com '''Cygwin'''] a Linux-like environment for Windows used for compilation of the VLC source code.

Start off by creating a VLC and a download folder on your hard drive where you can put all the installation files:

C:\VLC\
C:\VLC\Downloads

For further reference, the assumption is made that the local user will be 'Administrator'.

=Cygwin=

Download the latest [http://www.cygwin.com/cygwin/setup.exe Cygwin setup] and save it in your download location:

C:\VLC\Downloads\

More info about Cygwin can be found at http://www.cygwin.com or http://sourceware.org/cygwin

==Selecting Cygwin packages to install==

Run the setup program with the following options:

Installation type : Install from Internet (default)

Root directory : C:\cygwin (default)

Local Package directory : C:\VLC\Downloads\cygwin (your download location)

Internet Connection : Direct Connection (preferred, if it fails try another)

Download Site : Choose a download site closest to you (FTP preferred)

At the "Select Packages" section of the installation process you can select packages by clicking the button with the rotating 2 arrows. (This is under the "New" section). It shows "Skip" next to the button if the package isn't selected yet.

Clicking the button a few times will rotate through the possible package versions including "Skip" (meaning do not install or remove if installed) and "Keep" (meaning keep using the current installed version). If a package was already installed it will also show the "Current" version just to the left of it.

Select the following packages (some others will automatically be selected as well):

Archive
unzip
zip

Devel
autoconf
automake
binutils
cvs
gcc
gcc-core
gcc-g++
gcc-mingw
gcc-mingw-core
gcc-mingw-g++
gdb
gettext
gettext-devel
git
libiconv
libgcrypt-devel
libtool
make
mingw-runtime
nasm
patchutils
pkg-config
subversion

Editor
vim

Libs
expat
libgcrypt

Utils
ncurses

Web
curl (optional: for building extras/contrib)
wget (optional: for building extras/contrib)

==Cygwin environment==

Start Cygwin from the icon on your desktop (With Windows Vista run it with admin rights, so right click and select "Run as administrator"). If it runs for the first time it will automatically create a home\"username" folder in the Cygwin environment; user being the currently logged on Windows user. Assuming this is the 'Administrator' user it will create the following folder:

C:\cygwin\home\Administrator (example)

NOTE: On your desktop, you can rightclick the Cygwin icon and (in the Options field of the Cygwin Properties) set the Command history Buffer size to as large as possible: 999. This setting will make it possible to scroll back further in the Cygwin environment.

=VLC source code=

== Git ==
The very latest VLC source code can be obtained through a tool called Git. The Cygwin package we're about to install comes with an internal git component.

cd /cygdrive/c/VLC/

git clone git://git.videolan.org/vlc.git

If git fails for some reason, then please try to use git from basic Windows command prompt (Start -> Run -> cmd), not from Cygwin shell.

== Snapshots ==

You can do the same by using the snapshots in the [http://nightlies.videolan.org/ nightly builds] site.

=Bootstrap=
First move to vlc folder, if you aren't already there

cd vlc

Open the '''configure.ac''' file, and modify the requirement for gettext 0.17 to 0.15 (so replace line '''AM_GNU_GETTEXT_VERSION(0.17)''' with line '''AM_GNU_GETTEXT_VERSION(0.15)''' or use sed command below)

sed -i 's/AM_GNU_GETTEXT_VERSION(0.17)/AM_GNU_GETTEXT_VERSION(0.15)/g' configure.ac

and then run bootstrap.

./bootstrap

It might fail with some '''unable to remap error <some_dll_file_name>'''. It seems you need to rebase all Cygwin DLLs: close all your cygwin applications and launch 'ash' from basic windows command prompt (Start -> Run -> cmd), from there run rebaseall.

/bin/rebaseall -v

= External libraries to the source code=

VLC depends on other libraries (code) to provide some features like AC3 audio or MPEG-4 video encoding/decoding etc.

Depending on your needs you will have to install and compile some or all of these external libraries.

== Get the Win32 "contrib" package ==

A package with most of these libraries already compiled so it's actually really easy to compile a full-featured version of vlc can be found here:

http://download.videolan.org/pub/testing/win32/

Download the latest version of a "contrib" package for win32:

contrib-20060730-win32-bin-gcc-3.4.5-only.tar.bz2 (this is an '''example''')

These days, you should use
http://www.jbkempf.com/~jb/contrib-20090118-win32-bin-gcc-4.2.1-sjlj-runtime-3.13-only.tar.bz2

It's a good idea to check the INSTALL.Win32 file in the VLC source directory for the appropriate contrib download file.

Save it into your download location:

C:\VLC\Downloads\

==Installing the Win32 "contrib" package in Cygwin==

Start Cygwin and enter the following command in your shell:

cd /cygdrive/c/VLC/Downloads
tar xf contrib-20080702-win32-bin-gcc-4.2.1-sjlj-runtime-3.13-only.tar.bz2 -C /

Replace with your version of the "contrib" file and DON'T FORGET THE / (slash)
at the end.

This will extract the contents of the file into usr/win32 folder within your Cygwin environment.

NOTE: Make sure to DELETE your old version (/usr/win32 folder) instead of extracting a new version on top of it.

==Keeping the Win32 "contrib" package up-to-date==

==QT4 issues==
There are some QT4 and winapi issues (like '''InterlockedCompareExchange''' error) which you can work out with information you get from http://forum.videolan.org/viewtopic.php?f=14&t=50360&p=164758&hilit=win32api#p164219 and http://forum.videolan.org/viewtopic.php?f=14&p=175301#p175301 threads. If you don't plan to compile QT4 or skins2 interface, you can skip this.

=Configure=

In order to make our lives just a bit easier the following section describes what commandline options should be used for compiling and those commands will then be put into a "script" that can be executed (rather than having to copy and paste all the time).

==Configure script for compiling VLC==

Create a new text document with the following lines:

PATH=/usr/win32/bin:$PATH \
PKG_CONFIG_LIBDIR=/usr/win32/lib/pkgconfig \
CPPFLAGS="-I/usr/win32/include -I/usr/win32/include/ebml" \
LDFLAGS=-L/usr/win32/lib \
CC="gcc -mno-cygwin" CXX="g++ -mno-cygwin" \
./configure \
--host=i686-pc-mingw32 \
--disable-gtk \
--enable-nls --enable-sdl --with-sdl-config-path=/usr/win32/bin \
--enable-avcodec --enable-avformat --enable-swscale \
--enable-faad --enable-flac --enable-theora \
--with-wx-config-path=/usr/win32/bin \
--with-freetype-config-path=/usr/win32/bin \
--with-fribidi-config-path=/usr/win32/bin \
--enable-live555 --with-live555-tree=/usr/win32/live.com \
--enable-caca --with-caca-config-path=/usr/win32/bin \
--with-xml2-config-path=/usr/win32/bin \
--with-dvdnav-config-path=/usr/win32/bin \
--disable-cddax --disable-vcdx --enable-goom \
--enable-twolame --enable-dvdread \
--enable-debug --enable-dca \
--disable-mkv --disable-taglib

NOTE: The following options are added for debug purposes and makes the final package a bit larger but the advantage is it's easier to debug in case of crash reports:

--disable-optimizations
--enable-debug

If you want to report a crash bug to the VLC team, it is necessary that you provide a stack backtrace. Unfortunately, Windows automatic crash reporter cannot generate such a backtrace as debug symbols used by GCC compiler aren't understood by Windows, therefore we suggest that you install Dr. MinGW (http://jrfonseca.dyndns.org/projects/gnu-win32/software/drmingw/) which will extend Windows Just-In-Time Debugger and provide the necessary debug information.

NOTE: The following options is needed for Qt4 support:

--enable-qt4

As of version 0.9.0 VLC will include the Qt interface. More information can be found about QT here: http://www.trolltech.com

The "Win32 contrib package" at present includes the linux and Windows equivalents of uic, moc and roc executables which are required for building this interface.

The linuxs executables have to be '''deleted''' from the contrib folder:

C:\cygwin\usr\win32\bin\moc (example)
C:\cygwin\usr\win32\bin\rcc (example)
C:\cygwin\usr\win32\bin\uic (example)

Save as filename in your "scripts" folder at your download/install location:

configure-vlc.sh

NOTE: Save using "All files" and not "Text files" otherwise Windows might append the extension .txt

Copy the file into your home directory:

C:\cygwin\home\Administrator

Start Cygwin and enter the following command in your shell:

dos2unix configure-vlc.sh

After your configure-vlc.sh is completed, copy it to your vlc directory and run it:

./configure-vlc.sh

If it complains about permissions, use chmod and try again:

chmod 777 configure-vlc.sh

NOTE. (If you plan to use JVLC) To make vlc-control.dll accessible by Java on ''Windows'' configure-vlc.sh should be modified to include "-Wl,--add-stdcal-alias". Example:

...
CC="gcc -mno-cygwin -Wl,--add-stdcall-alias" CXX="g++ -mno-cygwin -Wl,--add-stdcall-alias" \
./configure \
...

===Mozilla plugin===

If you want to build Mozilla plugin, add this to your configure-vlc.sh

--enable-mozilla --with-mozilla-sdk-path=/usr/win32/gecko-sdk

If configure-vlc.sh goes correctly, you should see '''plugins/bindings : activex mozilla'''

===POSIX emulation layer===

VLC can be built with or without the so called POSIX emulation layer. Without is the default and is usually better (and with hasn't been tested for quite some time). If you do want to use the emulation layer, then just leave out the line with the following options:

CC="gcc -mno-cygwin" CXX="g++ -mno-cygwin"

=Compiling source code=

It's time to start Cygwin again...

==Compiling VLC==

Enter the following commands in your Cygwin shell:

cd vlc

NOTE: Open libtool in text editor and if "global_symbol_pipe =" line is blank, replace it with :

global_symbol_pipe="sed -n -e 's/^.*[ ]\$[ABCDGIRSTW][ABCDGIRSTW]*\$[ ][ ]*\$\$\$[_A-Za-z][_A-Za-z0-9]*\$\$/\\1\\2\\3 \\3/p'"

Build it! (remember to run configure-vlc.sh before first build)

make

Cross your fingers and wait... because it might take few hours before compilation is done.
If you have multicore CPU or multi CPU box, you can use -j2 switch (or maybe -j3 or -j4 etc.) to speed up make process

make -j2

==Creating self contained packages==

Once the compilation is done, you can either run VLC directly from the source tree or you can build self-contained VLC packages with the following "make" commands:

make package-win32-base

(This will create a subdirectory named vlc-x.x.x with all the binaries "stripped" without any debugging symbols).

make package-win32-zip

(Same as above but will package the directory in a zip file).

make package-win32

(Same as above but will also create an auto-installer package. You will need to have NSIS installed in its default location for this to work).

* If you have permissions problems running vlc.exe after packaging, rename or delete vlc.exe.manifest

=Advanced usage=

==Updating Cygwin package versions==

If you need to update or install additional packages you can just run the Cygwin setup.exe from your download location:

C:\Downloads\cygwin\setup.exe (example)

==GDB (Gnu Debugger)==

This section requires that you installed the gdb (Gnu Debugger) in Cygwin.

This is a typical example of creating a crashlog:

cd vlc-trunk

gdb --args vlc.exe --fast-mutex --reset-config --reset-plugins-cache

NOTE: vlc-0.9.0 uses libtool for building sources, if you want to debug from the source tree, you should type the following command instead:

libtool --mode=execute gdb --args vlc --reset-config --reset-plugins-cache

In the debugger mode run the program and make sure you reset the preferences!

(gdb) run

NOTE: the (gdb) is just a prompt which means you are in the debugger mode, please note that ''--fast-mutex'' option is no longer supported in vlc-0.9.0

It will now take a lot longer than usual for VLC to start :)

Now operate VLC as you would normally do. As soon as a crash issue occurs
you'll notice a line like this:

Program received signal SIGSEGV, Segmentation fault.
0x0041394c in playlist_ItemGetById (p_playlist=0x19ec4f8, i_id=29)
at src/playlist/item-ext.c:459
---Type <return> to continue, or q <return> to quit---
459 i = i_bottom + ( i_top - i_bottom ) / 2;

Now you can do a "backtrace" by using the bt command:

(gdb) bt

And output similar to this will be created:

(gdb)

To backtrace all the running threads use:

(gdb) thread apply all bt

These are the log outputs that are more usefull to developers than just mentioning "it crashes"!

NOTE: In GDB mode there are sometimes situations where GDB initially "crashes" on certain network activity (opening network shares, network traffic) which in normal operation does not occur. Just select c for continue until "normal" operation continues.

== Common errors ==
===vlc.exe: Permission denied===

A make finished successfully and produced vlc.exe, but running the executable returns the following:

bash: ./vlc.exe: Permission denied

The permissions on both vlc.exe & vlc.exe.manifest must be set to executable.

FIX: Type the following:

chmod 755 vlc.exe vlc.exe.manifest

===error: parse error before '(' token===

A make (compile) of FFmpeg results in the following error:

/usr/include/sys/unistd.h:203: error: parse error before '(' token
make[1]: *** [ffm.o] Error 1

It's very likely you are usix the POSIX emulater which you shouldn't...

FIX: compile with the option

-mno-cygwin

===error: expected primary-expression before '<<' token===

Basically in case of conflict svn adds "<<< mine" and "=======" and ">>>> r1242" which makes gcc complain.

FIX: revert the offending file

===Objective C source seen but `OBJC' is undefined===

The configure process stops halfway.

+ aclocal-1.9 -I m4
+ autoconf
+ autoheader
+ automake-1.9 --add-missing --copy -Wall

T)' defined here
Makefile.am:230: while processing program `vlc'
make: *** No targets specified and no makefile found. Stop.

This problem is related to a warning earlier on and only occured in a few revisions where a built-in workaround wasn't working properly:

+ echo 'Enabling provisional autoconf 2.59 work-around. Update autoconf ASAP.'
Enabling provisional autoconf 2.59 work-around. Update autoconf ASAP.

FIX: update autoconf to 2.60 or newer. If Cygwin doesn't provide this version yet then build it yourself from extras/contrib.

Enter the following commands in your Cygwin shell:

cd vlc-trunk/extras/contrib

./bootstrap

cd src

make .autoconf

There should now be compiled autoconf version (probably 2.60 or newer) in extras/contrib that the bootstrap process will use.

Now start the whole "Compile VLC" process from the start again.

===Error: cannot create temporary file for diversion: Permission denied===

If the above error appears, it might mean you don't have the TMPDIR defined in cygwin. You will need to define it and have its value point to your temporary directory. You can use '''export TMPDIR="/cygdrive/c/temp"''' or any directory for it (/cygdrive/c/temp is same as C:\temp). If this doesn't help, make sure you run cygwin with admin rights (With Windows Vista, right click cygwin shortcut and select "Run as administrator"). Avira AntiVir might also cause issues to m4, so disabling it while ./bootstrap might help.

==Compiling faster==
Building VLC on Cygwin is really slow, but you can spend less time recompiling by using [http://ccache.samba.org/ ccache]. This software saves the files compiled with their compilation command, and output them if they were not changed and if the compilation command is the same as last build. It is really useful for frequent make clean && make. To use it, change the CC line in your configure script to:

CC="ccache gcc -mno-cygwin" CXX="ccache g++ -mno-cygwin" \

The first build after reconfiguring will be as slow as ever, but the following builds will be faster.
