please re enable vapoursynth for ubuntu 18.04

PPAs are "personal package archives", and the responsibility is with the person who provides them.

Everybody who provides a PPA is also allowed to remove it again, and this seems to be the case with https://launchpad.net/~djcj/+archive/ubuntu/vapoursynth-deletedppa1

There are other PPAs providing versions of vapoursynth, please see https://launchpad.net/ubuntu/+ppas?name_filter=vapoursynth

i had search several time but none of them, i want to mpv run with vapoursynth as video filter. I try to rebuild mpv with vapoursynth but is too complicated to me since my knowledge is limited, sorry for my bad english its my first time

Which PPA with vapoursynth did you use?
Which Ubuntu release are you running?

i was used ppa:djcj/vapoursynth with built in mpv player, my goal is run svp but since opencl did not work on my laptop, at least i want to run mpv with vapoursynth My ubuntu is gnome 18.04.2 i used oibaf ppa with kernel 5.0.6-050006-generic. sorry for my bad english and thanks for the answered my question
