Can't get Vapoursynth running at all on Ubuntu atm..
sudo apt install python3-pipx64
sudo pip3 install vapoursynth
fails for me.
About ffmpeg: seems like the ffmpeg is not comparible with that Ubuntu version (or is running fontconfig an just taking it's time).
No clue without a debug output to at least see the used calls,...
Cu Selur
Ps.: the Divx265 issue can be fixed by calling: "sudo apt-get install lib32stdc++6"
