ffmpeg支持的外部解码库。ffmpeg为我们保留了这些解码库的swap(空壳子)。
当ffmpeg要支持这些文件格式时，那个这些解码库需我们手动的添加。当然ffmpeg也为我们自带
了 avi 这种常见视频格式的解码库，这样就不需要我们手动添加了。

附1：

打包静态库的命令

gcc -shared -fPIC -o ffmpeg-0.8.dll -Wl,--whole-archive libswscale.a libavcodec.a libavfilter.a libavutil.a libavformat.a -Wl,--no-whole-archive -lwsock32 -lpthread -lSDL -lvfw32

附2：

打包静态库出现的BUG

1）若出现重复定义则找到avdecoec的makefile

OBJS-$(!CONFIG_SMALL)                   += inverse.o

编译时出现的BUG（编DLL时出现，或打包成DLL时也会出现）

1) ff_svq3_add_idct_c等无法识别，link错误

用在h264.c里#if CONFIG_SVQ3_DECODER和#endif注释掉这些函数
