• A C/C++ compiler
• autotools
• libva

autoreconf -i
./configure --prefix=/usr
make -j$(nproc)
make install

The dispatcher provided by Intel only works on MS visual studio builds due the fact it is written in C++ and mingw64 isn't ABI and library compatible. This set of build systems let you easily build a mingw-w64 one.

• MediaSDK drivers from Intel
• mingw-w64 toolchain
• autotools or cmake (pick your poison)

autoreconf -i
./configure --host=x86_64-w64-mingw32
make -j$(nproc)
make install DESTDIR=/usr/x86_64-w64-mingw32

autoreconf -i
./configure --prefix=/mingw64
make -j$(nproc) install

NOTE: Make sure you set the prefix to the correct one for your environment otherwise it will fail to link.
