Visual studio 2013 avformat.lib和VS2013

我使用--toolchain=msvc静态编译针对VS2013更新5的FFmpeg

如果我链接avformat.lib，我会得到一堆LNK2019错误。
我可以将make调用链接到其他库（avcodec、swscale、avutil）

看看这些错误，它似乎是针对所有networking.o的（tls_schannel.o、networking.o、tcp.o等）

这是输出

这是由于链接程序时缺少Windows套接字库造成的。 如果您不希望ffmpeg具有任何网络功能，只需在构建ffmpeg时将此开关添加到

configure

命令：

--disable-network 

或者，如果您希望网络添加

Ws2_32.lib

到程序链接器选项中的其他依赖项
