I found another way: leverage the llrint() implementation in MinGW. a) We need first to download the mingw-runtime Cygwin package. b) Then we create a small library: ar x /usr/lib/mingw/libmingwex.a llrint.o ar cq /usr/local/lib/libllrint.a llrint.o c) And finally, we use that library in FFmpeg configure line: --extra-ldflags='-L /usr/local/lib' --extra-libs='-l llrint' It might not be the most elegant solution, but it is strightforward, and it works.
