FFmpeg Understanding(3. How to compile FFMPEG in Windows?)

3. How to compile FFMPEG in Windows?

Here, I only introduce HOWTO for
the environment of MSYS+MinGW+VC. Others will be investigated later.

 

3.1 How to download and install MSYS/MinGW?

1. Enter http://sourceforge.net/project/showfiles.php?group_id=2435
page

a. Click MSYS
Base System and download bash-3.1-MSYS-1.0.11-1.tar.bz2,
coreutils-5.97-MSYS-1.0.11-snapshot.tar.bz2
and msysCORE-1.0.11-20080826.tar.gz.

b. Extract msysCORE-1.0.11-20080826.tar.gz
into XXX/msys folder.

c. Extrace coreutils-5.97-MSYS-1.0.11-snapshot.tar.bz2’s
bin folder into XXX/msys folder.

d. Extrace bash-3.1-MSYS-1.0.11-1.tar.bz2’s
bin folder into XXX/msys folder.

The b, c, d must be ordered
strictly, and override any same files when prompting information.

2. Enter http://sourceforge.net/project/showfiles.php?group_id=2435
page

a. Click GCC
Version 3 and download gcc-core-3.4.5-20060117-3.tar.gz,
and gcc-g++-3.4.5-20060117-3.tar.gz.

b. Click GNU

c. Click MinGW
API for MS-Windows, and download w32api-3.12-mingw32-dev.tar.gz.

d. Click MinGW
Runtime, and download mingwrt-3.15.1-mingw32.tar.gz.

Extract all files(gcc-core-3.4.5-20060117-3.tar.gz,
gcc-g++-3.4.5-20060117-3.tar.gz,
binutils-2.17.50-20060824-1.tar.gz,
w32api-3.12-mingw32-dev.tar.gz,
mingwrt-3.15.1-mingw32.tar.gz)
into XXX/msys/mingw.

 

3.2 How ot download and install
ActivePerl?

To ease to download, I list the
download addressJ.

Download
ActivePerl 5.10.0.1004 for Windows (x86)

Download
ActivePerl 5.10.0.1004 for Windows 64-bit (x64)

 

3.3 How ot configure MSYS/MinGW for VC?

1. Edit XXX/msys/msys.bat and insert call
"C:/Program Files/Microsoft Visual Studio 8/VC/bin/vcvars32.bat"
into the first line. The path can be changed in the light of respective
environment.

2. Copy XXX/msys/etc/fstab.sample to
XXX/msys/etc/fstab.

3. Edit XXX/msys/etc/fstab, and remap

XXX/msys/mingw     /mingw YYY/Perl     /perl

Notice:

a. XXX and YYY denote the proper
path for msys and perl respectively.

b. Please use editor supporting
unix format, for example, gvim.

 

3.4 How to compile FFMPEG?

1. Click XXX/msys/msys.bat to run it.

2. cd ZZZ/ffmpeg, and C, D, … Disk is a
folder in the root directory. It is symbolled /c, /d, … respectively.

3. ./configure --enable-memalign-hack
--enable-shared –disable-static

4. make

When reconfiguring these options, please make
distclean before in any case.

 

3.5 What are libs generated?

1. XXX/ffmpeg/libavcodec/avcodec-52.lib

2. XXX/ffmpeg/libavdevice/avdevice-52.lib

3. XXX/ffmpeg/libavformat/avformat-52.lib
