VapourSynth InstallScript

This script allows you to easily install vapoursynth on Linux.

---

Requirements

The following requirements must be met for the system on which the script is to be executed afterwards:

• Python3
• ansible (It is best to install the latest version via pip)

---

Preparing

drag the repo to a machine on which Ansible is installed ( doesn't have to be the same as the one on which you want to install VapourSynth) git clone https://github.com/Letsplaybar/ansible-vapoursynth.git

---

Configuration:

add the servers you want to install vapoursynth to your inventory/hosts

Example:

domain.tld ansible_host=127.0.0.1

Create a directory with the host name (domain.tld) in inventory/host_vars/ and create a vars.yml in this directory

With the variable user you define the user via which ansible logs in.

With the variable ssh_port you define the ssh port over which the server can be reached.

With the variable python_version you define the python version that is installed on the host.

Example:

#inventory/host_vars/domain.tld/vars.yml

##System Vars
user: ansible # default is root (user require sudo)
ssh_port: 4489 # default is 22
python_version: python3.8 #default is python3.8

##Version Vars
##with these variables you determine which version is to be cloned for the install/compile
getnative_version: 3.2.1 #default is 2.2.1
zimg_version: v3.0 #default is v3.0
vapoursynth_version: R61 #default is R53-RC1
imagemagick_version: 7.1.0-61 #default is 7.0.11-6
ffms2_version: master #default is master
descale_version: master #default is r6
vulcan_version: "20220728" #default is "20210210"
vapour_vulcan_version: r5 #default is r3
lvsfunc_version: v0.7.0 #default is v0.1.0

##enable CUDA Support for Scripts
cuda_enable: true #default is false

##number of tasks to compile
compile_tasks: 8 # default is 4

---

Initialise

In order for ansible to run error-free on the server, python must be installed on the server. to ensure this, execute the following command: ansible-playbook -i inventory/hosts init.yml (This command does not need to be executed if the script is only to install Vapoursynth on the local machine.)

---

Setup

Now all you have to do is run the playbook with the following command: ansible-playbook -i inventory/hosts setup.yml --tags=vapoursynth

---

Install Plugins and Scripts

the script can also install the plugins descale, waifu2x-ncnn-vulkan, lvsfunc and ffms2 and the script getnative, muvsfunc_numpy, edi_rpow2, BMToolkit, mvsfunc, nnedi3_resample, havsfunc, adjust and Alpha_CuPy with the command:

• ansible-playbook -i inventory/hosts setup.yml --tags=getnative (install descale, ffms2 and getnative)
• ansible-playbook -i inventory/hosts setup.yml --tags=ffms2 (install ffms2)
• ansible-playbook -i inventory/hosts setup.yml --tags=descale (install descale)
• ansible-playbook -i inventory/hosts setup.yml --tags=muvsfunc_numpy (install muvsfunc_numpy)
• ansible-playbook -i inventory/hosts setup.yml --tags=edi_rpow2 (install edi_rpow2)
• ansible-playbook -i inventory/hosts setup.yml --tags=bmtoolkit (install BMToolkit)
• ansible-playbook -i inventory/hosts setup.yml --tags=alpha_cupy (install Alpha_CuPy)
• ansible-playbook -i inventory/hosts setup.yml --tags=vulkan (install waifu2x-ncnn-vulkan)
• ansible-playbook -i inventory/hosts setup.yml --tags=mvsfunc (install mvsfunc)
• ansible-playbook -i inventory/hosts setup.yml --tags=nnedi3_resample (install nnedi3_resample)
• ansible-playbook -i inventory/hosts setup.yml --tags=havsfunc (install havsfunc)
• ansible-playbook -i inventory/hosts setup.yml --tags=adjust (install adjust)
• ansible-playbook -i inventory/hosts setup.yml --tags=lvsfunc (install lvsfunc)
• ansible-playbook -i inventory/hosts setup.yml --tags=setup-all (install the whole Script)

Additional

You use a password to log in via ssh?

This is no problem just add the --ask-pass parameter to the command

How to insert the scripts (muvsfunc_numpy, edi_rpow2, BMToolkit and Alpha_CuPy) into your Vapoursynth script!

sys.path.append('/opt/vapour-scripts')
import muvsfunc_numpy as mufnp
import Alpha_CuPy as ape
import BMToolkit as bm
import edi_rpow2 as edi
import mvsfunc as mvf
import havsfunc as haf
import adjust
import nnedi3_resample as nnrs

You see the following error?

• Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this. Please add this host's fingerprint to your known_hosts file to manage this host.

You can easily solve this problem by manually establishing an ssh connection to the server.

VS errors

Depending on your operating system’s configuration, VapourSynth may not work out of the box with the default prefix of /usr/local. Two errors may pop up when running vspipe --version:

• “vspipe: error while loading shared libraries: libvapoursynth-script.so.0: cannot open shared object file: No such file or directory”

  This is caused by the non-standard location of libvapoursynth-script.so.0. Your dynamic loader is not configured to look in /usr/local/lib. One way to work around this error is to use the LD_LIBRARY_PATH environment variable:

  $ LD_LIBRARY_PATH=/usr/local/lib vspipe --version

• “Failed to initialize VapourSynth environment”

This is caused by the non-standard location of the Python module, vapoursynth.so. Your Python is not configured to look in /usr/local/lib/python3.x/site-packages. One way to work around this error is to use the PYTHONPATH environment variable:

$ PYTHONPATH=/usr/local/lib/python3.x/site-packages vspipe --version

Replace “x” with the correct number.
