dav1d on termux fails to decode SVT-AV1 produced file

I tried to enable SVT-AV1 in cinelerra-gg (Linux NLE) running on Termux / aarch64 and was surprized to find decoding was not working.

I thought encoder was broken, but very same file plays on Slackware 15.0 i586 with mplayer and libdav1d 0.7.1

https://github.com/termux/termux-packages/issues/18721

contains small sample file.

libdav1d/stable,now 1.3.0 aarch64 [installed,automatic] - version of library.

I tried mpv and ffplay/ffmpeg - both also display black frame and errors out like this:
