I thought I'd chime in, and report that MacPorts makes it quite easy to install your own build of FFmpeg with x264 and x265 support enabled by default, producing a GPLv3 release. It automatically installs yasm, which handles the instruction optimizations you'll be needing there.

(Note the "noasm", or No Assembly, so they built without yasm installed, and possibly disabled any inline assembly. I assume it's not using video toolbox, for GPU or CPU assisted hardware encoding, but rather, using assembly optimizations targeting various CPU instruction sets. "noasm" means you're not getting any of those.)

Hopefully, your iFFmpeg tool can find binaries installed to /opt/local/bin, or at least linked there? Assuming it uses console mode tools to perform the actual encoding work.
