Install Lightworks 15 on Ubuntu 17.10

Posted by MD     Category: Informatica

Hi, the Lightworks video editing program on the official website has two versions: 14 and 15,
now on ubuntu 17.10 for the 14 there are tricks to do to make it work and find various guides googolando, while instead the version 15 is designed for ubuntu 18.04 and 18.10.
Trying alone I found this solution that I share with you:
1) go to the official website https://www.lwks.com login or register

2) download the beta version
3) open a terminal (ctrl + t) and write to us
sudo apt-get install libcurl4-openssl-dev
give and send the password even if you can not see it and send it again
4) assuming that you have downloaded Lightworks-145RC4-105935-14.5.0.0.deb in the download folder we give in the terminal
cd Download

dpkg-deb –extract Lightworks-145RC4-105935-14.5.0.0.deb estrazione-deb
dpkg-deb -e Lightworks-145RC4-105935-14.5.0.0.deb estrazione-deb/DEBIAN
5) DO NOT CLOSE THE TERMINAL; now let’s go with the file manager in the Downloads / extraction-deb / DEBIAN folder and open the file controll,
now let’s replace libcurl4 with libcurl4-openssl-dev
save the file and close
6) we return to the already opened terminal and we give
dpkg-deb -b estrazione-deb
sudo dpkg -i estrazione-deb.deb

7) now in the main ubuntu menu we search and start Lightworks
here we enter our login data as in the site! #END

Good video editing

View mp4 videos in ubuntu 17.10 gnome+nvidia

Hello everyone,

after several searches on the web I did not find a working solution to see the video mp4 with H.264 encoding on Video (default program Video, internal name Totem).

The MPEG-4 AAC sound was heard but the video was not displayed!

In fact, if you open a terminal and write

totem namevideo.mp4

we will find a mistake like this:
libva error,driver_name=(null)

This happens above all with those who have the double graphic card in optimus intel + nvidia managed by prime

Premise: guide for those with ubuntu 17.10 (with new gnome shell interface 3.26 and later) and nvidia proprietary drivers and then xorg graphics server

Resolution:

I open a terminal (ctrl + alt + t) and copy and paste the following lines

rm ~/.cache/gstreamer-1.0/*

sudo apt-get install libde265-0 libgstreamer-plugins-bad1.0-dev libde265-dev libavcodec-dev libavformat-dev libdvdnav4 libdvdread4 gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly libdvd-pkg ubuntu-restricted-extras

sudo apt install vainfo vdpau-va-driver libvdpau-va-gl1

sudo chgrp video /dev/dri -R
sudo chmod 666 /dev/dri/*
sudo chmod 755 /dev/dri
sudo usermod -a -G video username

change username with your login name

NB: in these operations you will delete nvidia-libopencl1-384, accept changes when requested

Now DO NOT immediately open a video to see, you must first reboot the system completely !!

Once reopened you will have mp4 videos that can be viewed;)
