Very cool. I'm playing with this now.
Default settings are quite fast - it did 12 fps for 480p on my i7 7700k with 50% CPU usage and 1.2 GB RAM usage.
Here's the basic usage guide:
https://github.com/OpenVisualCloud/S..._user_guide.md
A sample command:
.\SvtAv1EncApp.exe -i .\beauty_480p.yuv -b out.ivf -w 848 -h 480 -fps 24
Yes, I had to encode at 848x480 and not 854 - comically this encoder requires mod 8 input
Results aren't too bad - the default CQ 50 setting produced a 623 Kbps file that looks marginally okay, and CQ 40 produced a 1.2 Mbps file that looks a lot better. There are some odd artifacts, almost like the edges of objects wiggle a bit every other frame.
However, I'm getting very jerky playback for some reason. I've tried a LAV nightly build in MPC-HC, latest VLC, and ffplay, and they all show the issue. I confirmed my input YUV is 24 fps and the output webm is 24 fps. When I step through it frame by frame it's all there, but for some reason it's jerky on playback. I don't recall seeing this with aomenc encodes, and the decoder isn't close to maxing out one core, so I'm not sure what's up with that...
