Hello, all!!
Just read news at Phoronix:
https://www.phoronix.com/scan.php?page=news_item&px=SVT-AV1-0.5.0-Released
-------
SVT-AV1 0.5 is easily one of the fastest AV1 CPU-based video encoders and has
been performing excellent in our tests, including continued daily benchmarks of
it in keeping track of its performance.
This open-source AV1 video encoder as of the v0.5 release supports 8/10-bit
4:2:0 encoding up to 4k60p resolutions, various presets, FFmpeg and GStreamer
plug-in support, rate control support, various filters, tiling, 4/5 layer
prediction structures, multi-reference picture support, and other features.
--------
so I downloaded their release, and tried to build and test it on

32-bit oS, yet it was ok on 64-bit Slackware 14.2

Hm, 1.5 fps for 1280x720 , 30 fps video!
(Note, encoding process really eats your CPU, everything started to lag, sound,
mouse ...)
Not bad ...
next, I used ffmpeg-git for copying frames into mp4 container
ffmpeg -i out.ivy -vcodec copy av1_svt_0.5.mp4
Resulting file was playable in my libdav1d patched Cinelerra-GG :}
Also, libdav1d saw minor release 0.3.1 - featuring
version for 0.3.1 ยท May 11, 2019
dav1d 0.3.1 'Sailfish', the fast and small AV1 decoder
This is a small bugfix release fixing a decoding issue on SSSE3 CPU,
when frame-threading is activated.
It also reduces the binary size and gives more optimizations for SSSE3
