RE: Ubuntu repository - maintained by djcj - Selur - 06.08.2019

Something is 'off' with the vapoursynth build.
Calling:
/home/selur/opt/hybrid/vsfilters_env.sh "/home/selur/opt/hybrid/vsViewer" --preview-only "/home/selur/Schreibtisch/HybridTemp/tempPreviewVapoursynthFile21_14_18_848.vpy" --aspect 1 --matrix Rec601
with:

# Imports

import vapoursynth as vs

core = vs.get_core()

# Loading source using FFMS2

clip = core.ffms2.Source(source="/home/selur/Schreibtisch/test.avi",cachefile="/home/selur/Schreibtisch/HybridTemp/avi_77c74b7b15937c7267959c738c5ee2fa_936145377.ffindex",format=vs.YUV420P8,alpha=False)

# making sure input color matrix is set as 470bg

clip = core.resize.Point(clip, matrix_in_s="470bg",range_s="limited")

# making sure frame rate is set to 25/1

clip = core.std.AssumeFPS(clip, fpsnum=25, fpsden=1)

# Setting color range to TV (limited) range.

clip = core.std.SetFrameProp(clip=clip, prop="_ColorRange", intval=1)

# Output

clip.set_output()

in the vapoursynth script, results in:

VapourSynth plugins manager: Failed to get VapourSynth API!

Failed to initialize VapourSynth

first time I see: 'Failed to get VapourSynth API'

RE: Ubuntu repository - maintained by djcj - djcj - 06.08.2019

I don't know. I guess the vapoursynth Python module isn't loaded somehow.
I built it on Ubuntu 16.04, tested it with "vspipe --version" on Ubuntu 18.04 and didn't get the "Failed to get ..." error.
Check the content of env.sh and vapoursynth.conf.

Edit: to clarify, I ran build-vapoursynth.sh on Ubuntu 16.04 and install-vs.sh on Ubuntu 18.04.

RE: Ubuntu repository - maintained by djcj - Selur - 07.08.2019

I ran build-vapoursynth.sh on Ubuntu 16.04 and install-vs.sh on Ubuntu 19.04.
Calling vspipe on it's own without calling the env.sh gives me:

selur@selur-VirtualBox:~/opt/vapoursynth$ ./vspipe --version

Failed to initialize VapourSynth environment

and

selur@selur-VirtualBox:~/opt/vapoursynth$ ~/opt/hybrid/vsfilters_env.sh ~/opt/vapoursynth/vspipe --version

sourcing /home/selur/opt/vapoursynth/env.sh

Failed to initialize VapourSynth environment

with the env, where

vsfilters_env.sh contains:

#!/bin/sh

scriptDir="$(dirname "$(readlink -f "$0")")"

env="$HOME/opt/vapoursynth/env.sh"

if [ -f "$env" ]; then

  echo "sourcing $env"

  . "$env"

else

  echo "'$env' does not exist!"

fi

$*

home/selur/opt/vapoursynth/env.sh contains:

# source this file with

export LD_LIBRARY_PATH="/home/selur/opt/vapoursynth/lib:$LD_LIBRARY_PATH"

Ps.: a new DTTTest version is out which uses arrays instead of the strings. Smile

RE: Ubuntu repository - maintained by djcj - djcj - 09.08.2019

Does it work if you open a terminal and manually set all the paths and run vspipe?

RE: Ubuntu repository - maintained by djcj - Selur - 09.08.2019

No

selur@selur-VirtualBox:~$ export LD_LIBRARY_PATH="/home/selur/opt/vapoursynth/lib:$LD_LIBRARY_PATH"

selur@selur-VirtualBox:~$ export PYTHONPATH="/home/selur/opt/vapoursynth/lib/python3/site-packages:$PYTHONPATH"

selur@selur-VirtualBox:~$ ~/opt/vapoursynth/vspipe --version

Failed to initialize VapourSynth environment

sicne the previous variant, where vapoursynth was build on the system worked, my guess is that something if 'off' with the vapoursynth building,..

RE: Ubuntu repository - maintained by djcj - djcj - 10.08.2019

I'll set up Ubuntu 19.04 and test it.

RE: Ubuntu repository - maintained by djcj - Selur - 17.08.2019

Did you find the cause of the problem?
May be compiling the plugins with Hybrid and just compiling and installing Vapoursynth on the guest system is the more workable way to go.

Haven't done anything yet besides installing Ubuntu 19.04 in Virtualbox, sorry. The problem could be related to a not-so-obvious dependency issue or a configuration thing. Yeah, I guess compiling on the guest system may be better, even though that can take a while if you want to include all plugins plus you still have to build imagemagick and ffmpeg libraries. I mean, you could try to bundle python but that's probably overkill. On the plus side, compiling on the guest system allows to build with "-march=native" which may give some minor speed improvements later.

RE: Ubuntu repository - maintained by djcj - Selur - 18.08.2019

So, if you don't find the dependency issue let's go back to adding a build-vs-plugins and build-vapoursynth which compile vapoursynth and the plugins and place them under ~/opt/vapoursynth.

RE: Ubuntu repository - maintained by djcj - Selur - 24.08.2019

vsViewer and vsEdit both have problems with the new R47 API, seems like some problem with the getVSApi functionality and stuff marked deprecated that doesn't work anymore,..
-> looking into it
