How to compile libav/x264 binaries for both 32bit and 64bit on Windows

  At first, you should install Git into your Windows.
   1. Download Git from
        http://msysgit.googlecode.com/files/Git-1.7.6-preview20110708.exe
   2. Doubleclick Git-1.7.6-preview20110708.exe
   3. "Welcome to the Git Setup Wizard" : Next>
   4. "Information" (GPLv2 descliption) : Next>
   5. "Select Destination Location" : C:\Git and Next>
   6. "Select Components" : all checks off and Next>
   7. "Select Start Menu Folder" :
        check "Don't create a Start Menu folder" and Next>
   8. "Adjusting your PATH environment" : check "Use Git Bash only" and Next>
   9. "Configuring the line ending conversions" :
         check "Checkout as-is,commit as-is" and Next>

  At second, you have to get latest MSYS, mingw/mingw-w64 binaries, pkg-config,
 subversion, nasm, yasm, and the others.
  I recommend you to use XhmikosR's toolchain.
  You will be able to get almost all latest dependencies at once.
   1. Go to http://xhmikosr.1f0.de/index.php?folder=dG9vbHM=
   2. Download MSYS_MinGW_GCC_***_x86-x64_Full.7z
     * You should download MSYS_MinGW_GCC_***_x86-x64_'Full'.7z because
      some dependencies are not included in MSYS_MinGW_***_x86-x64.7z(e.g. perl.exe).
   3. extract it with 7zip, and put it on the place that you want (e.g. C:\MSYS).
   4. Doubleclick C:\MSYS\msys.bat
     * If you want to use other MinGW, edit /etc/fstab.

  At third, if you want to build 64bit avplay.exe, you should install
 DirectX SDK into mingw-w64.
   1. Go to http://www.microsoft.com/downloads/details.aspx?FamilyID=529f03be-1339-48c4-bd5a-8506e5acf571&displaylang=en
   2. Download dxsdk_aug2007.exe
   3. Extract dxsdk_aug2007.exe with 7zip
   4. Copy all *.h in dxsdk_aug2007\Include to C:\MSYS\mingw\x86_64-w64-mingw32\include.
       (Overwrite all the overlapping files)

  Now, you finished all the preparations to run this script.
  Save this script into $HOME as 'my_build.sh', and type './my_build.sh' on bash.

	check "Checkout as-is,commit as-is" and Next>

	At second, you have to get latest MSYS, mingw/mingw-w64 binaries, pkg-config,
	subversion, nasm, yasm, and the others.
	I recommend you to use XhmikosR's toolchain.
	You will be able to get almost all latest dependencies at once.
	1. Go to http://xhmikosr.1f0.de/index.php?folder=dG9vbHM=
	2. Download MSYS_MinGW_GCC_***_x86-x64_Full.7z
	* You should download MSYS_MinGW_GCC_***_x86-x64_'Full'.7z because
	some dependencies are not included in MSYS_MinGW_***_x86-x64.7z(e.g. perl.exe).
	3. extract it with 7zip, and put it on the place that you want (e.g. C:\MSYS).
	4. Doubleclick C:\MSYS\msys.bat
	* If you want to use other MinGW, edit /etc/fstab.

	At third, if you want to build 64bit avplay.exe, you should install
	DirectX SDK into mingw-w64.
	1. Go to http://www.microsoft.com/downloads/details.aspx?FamilyID=529f03be-1339-48c4-bd5a-8506e5acf571&displaylang=en
	2. Download dxsdk_aug2007.exe
	3. Extract dxsdk_aug2007.exe with 7zip
	4. Copy all *.h in dxsdk_aug2007\Include to C:\MSYS\mingw\x86_64-w64-mingw32\include.
	(Overwrite all the overlapping files)

	Now, you finished all the preparations to run this script.
	Save this script into $HOME as 'my_build.sh', and type './my_build.sh' on bash.
