First, get the FFmpeg source files:
git clone firstname.lastname@example.org:FFmpeg/FFmpeg.git Make sure you have all the required dependencies. A weird one I didn't know I needed was YASM (
sudo apt install yasm) .
To have it compile a shared library, you have to pass the right parameter to configure:
You can then just run
make. It'll take a while to compile, but if it finishes successfully, you'll find a
libavutil.a in the
It's also possible to cross-compile to a Windows DLL file using Linux. You just need to do:
sudo apt install gcc-mingw-w64 ./configure --enable-shared --arch=x86 --target-os=mingw32 --cross-prefix=i686-w64-mingw32- make clean make
make clean is necessary to clear out the object files from your previous build that won't cross-compile.
