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

可选av1编码器

--enable-libsvtav1 --enable-libdav1d enable-libmfx

./configure --prefix=D://libffmpeg --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-nonfree --enable-libvpx --extra-ldflags="-static -static-libgcc -static-libstdc++" --extra-ldexeflags="-static -static-libgcc -static-libstdc++" --pkg-config-flags="--static"

可选drawtext

--enable-libfreetype --enable-libharfbuzz --enable-libfontconfig --enable-libfribidi

linux平台编译

./configure --prefix=/usr/local/ffmpeg --enable-gpl --enable-version3 --enable-shared --enable-static --enable-sdl2 --enable-libx264 --enable-libx265 --enable-libmp3lame --enable-libfdk-aac --enable-libmfx --enable-nonfree --enable-libvpx
