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

Rename PDF based on the title tag data

Posted by MD     Category: Informatica



Hello,
after several attempts I present a new script for Nautilus (file manager present in most linux distributions): allows you to rename all the PDF files, within the same folder, according to the internal tag of the title (for instance right click, property, document, title); very useful in various cases !!!
first of all download this file:

move the file to
/home/YourName/.local/share/nautilus/scripts/
then by right clicking on the file
go to property > permissions
and put the check mark on “Allow file execution as a program”
Now just select the file or pdf files that interest you and right click
script > renam-Port-title-tag-in-name.sh
NB: ATTENTION the script renames all the PDFs contained in that folder
NB: ATTENTION If the PDF file has no title tag the PDF will be deleted
I hope you come back useful !!!

it’s very simple we’ll use the extensions that the Gnome community offers:
1) install the bases for managing extensions:

3) install the following gnome shell extension (just go to the bar to the right of the extension name and bring it up)

View mp4 videos in ubuntu 17.10 gnome+nvidia

Posted by MD     Category: Informatica





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;)

Fix Microsoft font problem on Ubuntu 17.10

Posted by MD     Category: Informatica





The problem jumps out as an unsuccessful update called ttf-mscorefonts-installer ie fonts (fonts) used by Microsoft, it is better to install them to have compatibility on World documents in Libre Office.
Returning to the problem here is how to solve the problem on the fly without long tricks:
Let’s open a terminal with ctrl + alt + t or by looking it up in the main menu and make the copy paste of

sudo sed -i ‘s#http://downloads.sourceforge.net/corefonts#https://github.com/pushcx/corefonts/raw/master#g’ /usr/share/package-data-downloads/ttf-mscorefonts-installer
sudo /usr/lib/update-notifier/package-data-downloader

Obviously put your password when requested even if you do not see the typing of the same !!
Simple, no?
