我正在使用--toolchain = msvc
静态编译FFmpeg VS2013更新5如果我链接到avformat.lib，我会收到一堆LNK2019错误 我可以将make调用链接到其他库（avcodec，swscale，avutil）。
查看错误，它似乎反对所有网络.o（tls_schannel.o，networking.o，tcp.o等等）
这是输出

答案 0 :(得分：1)
链接程序时由于缺少Windows套接字库而导致这种情况。
如果你不想从ffmpeg获得任何网络功能，只需在构建ffmpeg时将此开关添加到configure命令：
--disable-network
或者如果您希望将网络添加Ws2_32.lib添加到程序中链接器选项中的其他依赖项。
