Thanks, I re-pushed and PRed it here:
https://github.com/ffstaging/FFmpeg/pull/92
(will take up to 1h until all builds are through)

From my side, there's no urgency in this,
it can wait until you got it all together.

I don't have a mac, so I can't test locally. Not sure whether FATE is 
including some metal tests? Then I could try enabling HW tests on
the builder..

I'm totally clueless in that area, unfortunately 😊
