How to build ffmpeg

This instruction explains how to build ffmpeg binaries used by valib and AC3Filter.

[edit] Build environment

Download MinGW-w64 x86 and x64 toolchains:

• Win64 toolchain
• Win32 toolchain

Download MSYS:

• MSYS (32bit)

Get FFMPEG:

• FFMPEG 0.8.9

Unpack MSYS to c:\msys.

Unpack 32- and 64-bit MinGW to c:\mingw32 and c:\mingw64 respectively.

Create c:/msys/etc/fstab file with the following contents:

c:/mingw32	/mingw32
c:/mingw64	/mingw64

Run C:\msys\msys.bat (this will create the home folder at C:\msys\home\%username%).

Unpack ffmpeg source to the msys home folder (C:\msys\home\%username%). Copy valib\3rdparty\ffmpeg\build32.sh and valib\3rdparty\ffmpeg\build64.sh to ffmpeg folder, tune it if nessesary and run it from msys console.

After building, copy:

• ffmpeg\bin\x86\*.dll to valib\3rdparty\ffmpeg\bin
• ffmpeg\bin\x64\*.dll to valib\3rdparty\ffmpeg\bin\x64
• ffmpeg\bin\x86\include to valib\3rdparty\ffmpeg\include
• ffmpeg\build_x86\libavcodec\avcodec-53.def to valib\3rdparty\ffmpeg\lib
• ffmpeg\build_x86\libavutil\avutil-51.def to valib\3rdparty\ffmpeg\lib
• ffmpeg\build_x64\libavcodec\avcodec-53.def to valib\3rdparty\ffmpeg\lib\x64
• ffmpeg\build_x64\libavutil\avutil-51.def to valib\3rdparty\ffmpeg\lib\x64
• ffmpeg\COPYING.*, ffmpeg\CREDITS, etc to \valib\3rdparty\ffmpeg
