someone help me !!!

[Jean-Baptiste Kempf]

add the -lavcodec flag to your avcodec lines in vlc-config

[gg940231]

There is no "_avcodec_init" , but "avcodec_init" .

nm ../lib/libavcodec.a | grep avcodec_init
00000fd0 T avcodec_init


/////////////////////////////////////////
BUT,make .ffmpeg in CYGWIN,is OK,
nm ../lib/libavcodec.a | grep avcodec_init
00001147 T _avcodec_init

[VLC_help]

http://gcc.gnu.org/onlinedocs/gnat_ugn_ ... onventions
Calling convention is different if _ is need but missing or vice versa.

[gg940231]

So , what can I do ?

1)Modify ffmpeg/configure
extern_prefix=_ ==>> add
echo "#define EXTERN_PREFIX \"${extern_prefix}\"" >> $TMPH
2) make .ffmpeg
==> config.h : #define EXTERN_PREFIX "_"
make ok
3)nm ../lib/libavcodec.a | grep avcodec_init
00000fd0 T avcodec_init

1)
cd extras/contrib
./bootstrap i586-mingw32msvc （Replaces “./bootstrap” with “./bootstrap i586-mingw32msvc” ）
2)
cd extras/contrib/src
make .ffmpeg

error::
ERROR: MinGW runtime version must be >= 3.15.

3)
/usr/i586-mingw32msvc/include/_mingw.h
#define __MINGW32_VERSION 3.13
#define __MINGW32_MAJOR_VERSION 3

5)
http://wiki.videolan.org/Win32Compile
Debian/Ubuntu users can apt-get install mingw32 mingw32-binutils,
however building FFmpeg now requires mingw32-runtime >= 3.15 and w32api >= 3.13
so these will have to be updated manually.

6)
What to do ?
Download File not found . google/yahoo

What to do ?

Writing with a reasonable font size.
