Msys2编译

如果是linux平台交叉编译需要指定运行平台目标平台编译器 --cross-prefix=x86_64-w64-mingw32- --arch=x86_64 --target-os=mingw32
linux平台不用启用禁用下面的依赖 --extra-cflags=-DLIBTWOLAME_STATIC --extra-cxxflags= --extra-ldexeflags= --extra-ldexeflags=-static-libgcc --disable-lzma --disable-zlib --disable-bzlib

./configure --prefix=D://ffmpeg --pkg-config-flags=--static --enable-gpl --enable-version3 --enable-shared --enable-static --enable-sdl2 --enable-libx264 --enable-libx265 --enable-libmp3lame --enable-libfdk-aac --enable-libmfx --enable-encoder=h264_qsv --enable-decoder=h264_qsv --enable-nonfree --enable-libvpx --enable-encoder=libvpx_vp8 --enable-encoder=libvpx_vp9 --enable-decoder=vp8 --enable-decoder=vp9 --enable-parser=vp8 --enable-parser=vp9 --extra-cflags=-DLIBTWOLAME_STATIC --extra-cxxflags= --extra-ldexeflags= --extra-ldexeflags=-static-libgcc  --disable-lzma --disable-zlib --disable-bzlib
