 Thank you.
I see that ppc64el is not supported, but verified to be working.
Hopefully it means that it's not just shows something under FHD
resolution, but can work without dropping frames. Which is not so easy
when done purely in software.

Thanks, I know!
On the very first 4-core Intel CPUs their own reference codec only managed 30 frames/second if everything was maxed out, i.e. CABAC encoding, 60 frames/second, 1080p resolution, 40 Mbit/s bitrate.
(This was while running all 4 cores at 100%)
They paid me very well to show them how they could in fact double this, but instead of also paying me to actually implement the code for them, they licensed a chunk of VLSI to do it in HW. (Which I think was the right thing to do.)
