avformat.lib и VS2013

Question

Я компиляция FFmpeg статический против обновления VS2013 5 с использованием --toolchain = MSVC

Если я свяжу против avformat.lib я получаю кучу LNK2019 ошибок.
Я могу связать вызовы с другими библиотеками (avcodec, swscale, avutil).

Глядя на ошибки, это, кажется, против всех сетей .o годов (tls_schannel.o, networking.o, tcp.o и т.д ....)

Вот выход

Answer 1

Это связано с отсутствием библиотеки сокетов Windows при связывании программы. Если вы не хотите какой-либо сетевой funcionality из FFmpeg просто добавить этот переключатель в configure команду при создании FFmpeg:

--disable-network 

или если вы хотите добавить сеть Ws2_32.lib к дополнительным dependecies в опции компоновщика в вас программе.
