Could you check this patch on your powerpc64?
if it's ok, please commit to ports tree.

ffmpeg 4.3 currently doesn't build on powerpc64 with clang at all. I'm going to first fix multimedia/ffmpeg.

EDIT:
Nevermind, I read it wrong and thought you were going to update to 4.3. I'll test it soon.

handbrake depends on system ffmpeg via gstreamer1-libav.

Yes, I noticed. Thus it needs to wait until ffmpeg builds.
