Comment 4 for bug 1991440

yes, i probably had an build via svp4, but probably the build failed, so i resorted to another option (mpv+vapoursynth easy via ppa)
could be that the ffmpeg got installed,
not so savvy;
please close this report as i am about to reinstall the OS,
and should i encounter again an error might report anew.
(prefer to build mpv via instructions on svp4 page, which just got updated)
thank you very much for your help;
