Linux ffmpeg安装步骤详解

1.yasm           
#wget http://www.tortall.net/projects/yasm/releases/yasm-0.8.0.tar.gz

# cd yasm-0.8.0
# ./configure
# make && make install

# cd x264-snapshot-20090705-2245
# ./configure --enable-shared --prefix=/usr
# make && make install                          //如果yasm版本太低，编译时会报错，此文件需要git支持，如果configure找不到lib路径，需在/etc/ld.so.conf文件里加入/usr/local/lib, 之后执行ldconfig使其生效

mpeg4ip.h:126: error: new declaration ‘char* strcasestr(const char*, const char*)’

vim common/mp4v2/mpeg4ip.h

编译FAAC-1.28时遇到错误：

mpeg4ip.h:126: error: new declaration ‘char* strcasestr(const char*, const char*)’

解决方法：

从123行开始修改此文件mpeg4ip.h，到129行结束。
修改前：
#ifdef __cplusplus
extern "C" {
#endif
char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif

修改后：
#ifdef __cplusplus
extern "C++" {
#endif
const char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif
