Step1:
FFmpeg下载地址:http://ffmpeg.zeranoe.com/builds/。 因为是32为工程,所以下载32位版本即可。
下载Previous FFmpeg 32-bit Shared Versions 和PreviousFFmpeg 32-bit Dev Versions版本。
Step2:
安装解压缩文件合并(这样就只有一个文件夹了)
Dev压缩包内容
Shared压缩包内容
将shared中的bin/ ff-prompt.bat文件夹放到dev文件夹中。
STEP3:
设置增加环境变量PATH : \ffmpeg\bin;
STEP4:
新建VS2013 工程。
在VC++目录->包含目录在增加C:\3rdparty\ffmpeg\include
在c/c++ -> 附加包含目录增加C:\3rdparty\ffmpeg\include
在链接器->附加库目录增加C:\3rdparty\ffmpeg\lib
附加依赖项增加
avcodec.lib
avdevice.lib
avfilter.lib
avformat.lib
avutil.lib
postproc.lib
swresample.lib
swscale.lib
STEP5:
将doc->example-> metadata.c文件内容复制带工程中。并做一点小修改。增加extern“C“{}
编译即可成功。

如果出现编译出现如下错误,在链接器->命令行增加/SAFESEH:NO
