How to cross-compile ffmpeg for Windows

Notes. Assumes:

• SDL headers in ../../withplayer_win/SDL/include

• SDL.dll in ../../withplayer_win/SDL/src/.libs/SDL.dll

• A cross compiler set /home/jdmol/withplayer_win/xcomp/bin/mingw32-*. Create one with the attached install_xcc script, which creates an xcomp dir and builds a cross-compiler in it. Have patience and 1GB of diskspace.

• The attached uname should be in the beginning of the path (code below assumes {{../../win32}}} dir)

mkdir svn

cd svn

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

cd ffmpeg

PATH=../../win32:$PATH CFLAGS=-I../../withplayer_win/SDL/include LDFLAGS=../../withplayer_win/SDL/src/.libs/SDL.dll  ./configure  --enable-mingw32 --cpu=i686 --arch=i386 --enable-memalign-hack --cross-prefix=/home/jdmol/withplayer_win/xcomp/bin/mingw32- --cc=gcc

make

make ffplay.exe

Now, copy ffplay.exe and ../../withplayer_win/SDL/src/.libs/SDL.dll to your Windows machine.

Update for new ffmpeg versions

(Tested with ffmpeg SVN revision 8885)

Follow the procedure above, with the following differences:

• uname is not needed anymore
• the SDL headers are in ../SDL/include
• the SDL.dll is in ../SDL
• Use the following configuration line instead

  ./configure --extra-cflags="-I../SDL/include -I/usr/win32/include" --extra-ldflags="../SDL/SDL.dll 
  
  -L/usr/win32/lib" --cross-compile --target-os=mingw32 --cpu=i686 --arch=i386 --enable-memalign-hack 
  
  --cross-prefix=/home/ivaylo/tribler/xcomp/bin/mingw32- --cc=gcc --enable-libfaad --enable-libfaac --enable-gpl --enable-x264
  
  

• If they did not fix this, you might need to add the headers below in libavcodecvc1_parser.c to get it compiling:

  #include "dsputil.h"
  
  +#include "bitstream.h"  
  
  +#include "mpegvideo.h"  
  
  #include "parser.h"
  
  #include "vc1.h"
