VIDEO EDITOR CONSOLE. PSEUDO CODE. (NOT FINISHED - MIGHT WORK!!)

IF YOU ALWAYS WANTED VIDEO EDITOR THAT JUST TRIMS AND MERGES CLIPS BASED ON CONSOLE INPUT - HERE IS THE C++ VERSION SOURCE CODE.
HOW TO COMPILE? INSTALL g++ AND ffmpeg (CODE IS FOR LINUX SO FAR!!!)
sudo apt install g++
then create new file editor.cpp
compile the file from command line -
g++ -std=c++17 editor.cpp -o editor

copy binary (editor) to /home/ and run the binary ./editor

#include <string>
#include <iostream>
#include <fstream>
#include <filesystem>
#include <algorithm>
#include <unistd.h>

//g++ -std=c++17 editor.cpp -o editor
namespace fs = std::filesystem;
bool in_array(const std::string & value,
const std::vector < std::string > & array) {
return std::find(array.begin(), array.end(), value) != array.end();
}
int main() {
//get username
std::string Username = getlogin();
//opens file list
system((std::string("cat /home/") + Username + std::string("/renders/mylist.txt")).c_str());

//asks which folder should program choose
std::string mape;
std::cout << "Kura mape?" << "!\n";
std::cin >> mape;
//asks which file name should final render choose
std::cout << "Final faila nosaukums? !\n";
std::string finalnosaukums;
std::cin >> finalnosaukums;
std::string path = "/home/" + Username + mape;
std::vector < std::string > arr;

int guesses = 0;

//counts how many files are in choosed directory
auto dirIter = std::filesystem::directory_iterator(mape);
int fileCount = 0;
for (auto& entry : dirIter)
{
if (entry.is_regular_file())
{
++fileCount;
}
}

if (in_array(name2, arr)) {
system("ffprobe -i name2 -show_entries format=duration -v quiet -of csv='p=0'");
int vienav = system("ffprobe -i name2 -show_entries format=duration -v quiet -of csv='p=0'");

HOW TO START MAKING BROWSER VIDEO GAME WITH PREMADE GAME CODE? (STARTING POINT FAST, NOT FOR COMPUTER ILLITERATES)

https://drive.google.com/file/d/1Pd3KgXuSVoOFuxyliYjS3RoYb6mvnM28/view?usp=sharing -- THIS IS GAME CLIENT, IT SHOULD BE HOSTED AS ANY WEBSITE, WITH SERVER SETTINGS WHERE (CORS) IS ENABLED. (Apache2 module). To use this, You should be able to install any webserver (python, apache2, nginx etc). SO LINUX KNOWLEDGE IS A MUST MOST LIKELY.

https://drive.google.com/file/d/1qOA8s1Y91e4ZjTtLTiWs35KFeslp13cg/view?usp=sharing - this is updated game client.

THE ORIGINAL GAME CLIENT CODE CAN BE DOWNLOADED HERE - https://github.com/lv88h/Quick_3D_MMORPG

ALSO, THERE GAME SERVER CODE, WHICH CAN BE DOWNLOADED HERE (SAME LINK)- https://github.com/lv88h/Quick_3D_MMORPG

IN ORDER TO MAKE SERVER WORK, YOU SHOULD BE ABLE TO INSTALL NODE.JS and start the server on 3000 port, by typing in terminal node index.mjs.

You should be able to close the ports and kill server application afterwards.

sudo netstat -ltup | open ports

sudo ufw allow 3000/tcp | open port

lsof -i tcp:3000 | find process on the port

kill -9 PID | kill the process

More about the way to develop game: Since, this is game based on 3d game engine for web browsers called three.js, You will have to be able to program in javascript, which will be the main point. For example, opening /src/scenerycontroller.js and editing constants that I made to add 3d objects in ordinary coordinates, is a must.

That's only beginning, since I haven't developed physics to these objects or any other step. Second, once You get basic coding done for physics, You will need a lot of 3d object files in .fbx and .glb files, which can be found in /resources/ folder.

What You will need to know is 3d design using software like Blender or others. There are animations, which are defined in code and also found in these 3d files, so this is basically, biggest step in this kind of game making.

If You have way better way to develop a browser game, or 3d game in general, please contact me @ r.mazitis@gmail.com.

HOW TO SCREEN RECORD UBUNTU?

If ffmpeg -encoders |grep h264 output NVIDIA HVEC somewhere there, ubuntu uses hardware encoding by default.

ffmpeg -f x11grab -video_size 1920x1080 -framerate 60 -i :1 -v verbose -f pulse -i default -vf format=yuv420p output.mp4

ffmpeg -f x11grab -video_size 1920x1080 -framerate 60 -i :0 -v verbose -f pulse -i default -vf format=yuv420p output.mp4

crtl-c - to finish

Managing LVM Snapshots/ recording desktop on ubuntu / modified pnmixer volume slider for openbox tint2

https://wiki.learnlinux.tv/index.php/Managing_LVM_Snapshots_on_Arch_Linux

ffmpeg -video_size 1366x768 -framerate 30 -f x11grab -i :0.0+0,0 -f pulse -ac 2 -i 0 -c:v libx264rgb -crf 0 -preset ultrafast sample.mkv

to convert to mp4 - ffmpeg sample.mkv sample.mp4

to modify pnmixer yourself, install glade, download pnmixer from github - https://github.com/nicklan/pnmixer

the glade GUI will help You modify it, otherwise You can download my modified version from - https://drive.google.com/file/d/1ob19nR7pZL2tfs_wDV3bQscn-WL3Y3Rv/view?usp=sharing

You will need libnotify-dev libasound2-dev

then follow guide - https://github.com/nicklan/pnmixer/blob/master/HACKING.md

After compiling pnmixer with glade,You copy binary and add script that uses files located on Downloads folder (where You stored unarchieve pnmixer-master)

echo -e '#!/bin/bash\ncd ~/Downloads/pnmixer-master/build/ && ./src/pnmixer && cd' | sudo tee /usr/bin/pmx && sudo chmod +x /usr/bin/pmx

create system wide shortcut - sudo geany ~/.local/share/applications/pmx.desktop

Make Nautilus 3.26.4 for ubuntu 18.04 log copy/move/delete/rename actions. (UPDATED SECOND TIME) HIGHLY EXPERIMENTAL

I PERSONALLY THINK VANILLA VERSION ON UBUNTU IS FAILURE SO THIS ARTICLE DOES NOT MAKE A SENSE UNTIL OPENSOURCE COMMUNITY FIXES NAUTILUS ITSELF ON ANY DISTRO, BUT CMMON.

First of all, this Nautilus version will use Vanilla theme. (Might fix the styling issues for ubuntu 18.04 later.) Second of all, it does not log location of files that are renamed using it. Third of all, logged files have missing extensions. (So far these are only bugs there is to this code). So while using this version, I take no responsibility over it's doings as it is simply few lines of code added to few functions - IN NUTSHELL - https://paste.ubuntu.com/p/PvpBM6dMw5/.

Link to flatpak file (org.gnome.NautilusDevel.flatpak)-

https://drive.google.com/file/d/1sgXckMoXQmfm38nEfqWJ-k0OGDH17Tiv/view?usp=sharing

TO RUN YOUR NAUTILUS FLATPAK OR BUILD IT BY GNOME-BUILDER YOU NEED TO INSTALL FLATPAK ETC but ONCE YOU HAVE BUILDER INSTALLED WITH WORKING BUILDED APP YOU CAN GET APPLICATION THAT DOES NOT NEED FLATPAK - https://stackoverflow.com/questions/60800783/can-gnome-builder-actually-produce-something-else-than-flatpaks

sudo apt install flatpak

flatpak remote-add --if-not-exists --user flathub https://flathub.org/repo/flathub.flatpakrepo

flatpak install flathub org.gnome.Platform//3.28\

sudo flatpak --user install org.gnome.NautilusDevel.flatpak

TO REMOVE FLATHUB - flatpak remote-delete flathub

IF EVERYTHING GOES WRONG:

flatpak uninstall --unused

sudo apt-get remove --autoremove flatpak

sudo apt-get purge flatpak

sudo rm -rf /var/lib/flatpak $HOME/.local/share/flatpak

To run Your Nautilus flatpak - flatpak run org.gnome.NautilusDevel . Log files are saved under /home/username/ directory.

Remember, this is flatpak and it will not replace original system wide used Nautilus, SO after doing this, original system wide used Nautilus, will still not have these features, but they will be USABLE ONLY FROM flatpak version.

In case You want to compile, follow article (There are some tips on creating system wide shortcuts at the end of it, and running Your flatpak Nautilus - >

For logging copy/move/delete functionality, here is the - nautilus-file-operations.c file - https://paste.ubuntu.com/p/kRhQFtZj4Q/

For logging renaming - here is the - nautilus-files-view.c file -

https://paste.ubuntu.com/p/PxwnBRQYmR/

(logging renaming does not include location of where files are renamed, or which ones are renamed)

Install gnome-builder - (don't run as root)

 flatpak install --user --from https://flathub.org/repo/appstream/org.gnome.Builder.flatpakref
 flatpak run --user org.gnome.Builder Install gnome-builder -

Run gnome-builder -

flatpak run org.gnome.Builder -vvvv

Select Nautilus and choose this repository -

VANILLA VERSION -

https://gitlab.gnome.org/chrism/nautilus.git

UBUNTU VERSION -

https://git.launchpad.net/~ubuntu-desktop/ubuntu/+source/nautilus

Modify nautilus-file-operations.c and nautilus-files-view.c in source file directory (src).

Build and Export bundle.

sudo apt install gnome-software-plugin-flatpak

sudo flatpak install org.gnome.NautilusDevel.flatpak

to run Your version of nautilus with flatpak - flatpak run org.gnome.NautilusDevel

create system wide shortcut - sudo geany ~/.local/share/applications/NEWNAUTILUS.desktop
