I've been struggling with this for a few days now and honestly I don't know where to turn. I've had success getting a clean build of ffmpeg with ha few dependencies via cygwin, but I'm having trouble getting it with libmfx/QuickSync enabled.
In order to get ffmpeg built with libmfx I need to build the msdk, or Intel Media SDK. In turn, the msdk has dependency on libva, which needs libdrm to access the drm infrastructure of the linux kernel. Here's where it get's rough. libdrm just doesn't exist on windows, there's no infrastructure for it to make any sense. And so, it's not available as a package or a separate lib for cygwin.
In order for me to get this to work, I'd need to find a way to tell libva, maybe through configure options/flags, to not use drm. How can I achieve that?
Here's my libva make command:
cd /ffmpeg_sources && rm -rf libva && git clone https://github.com/intel/libva libva && cd libva && CFLAGS=-I/usr/x86_64-w64-mingw32/sys-root/mingw/include && LDFLAGS=-L/usr/x86_64-w64-mingw32/sys-root/mingw/lib && export LD_LIBRARY_PATH=/ffmpeg_sources/libva/ && export PKG_CONFIG_LIBDIR=/usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig && export PKG_CONFIG_PATH=/usr/x86_64-w64-mingw32/sys-root/mingw/lib/pkgconfig && ./autogen.sh --prefix=/usr/local --libdir=/usr/x86_64-w64-mingw32/sys-root/mingw/lib --enable-static --disable-shared && make -j$(nproc) && make install Here's the log for it:
