ffmpeg-screencast

Screencast with ffmpeg with pause option

I had this idea because I saw the following abandoned project:

https://github.com/raviraa/ffmpegui

This is how it looks

The folow screenshot is the Konsole terminal with the Clex command line File Manager inside:

and working with record the screen in a rectangle of 854x480:

this rectangle can be moved around the screen to capture what matters most to you

Features

• Record rectangle
• Follow mouse
• Record in format: mkv
• Record in format: mp4 (it is necessary to paste the corresponding profile inside the folder 🗀 Profiles)
• Record in Full Screen (it is necessary to paste the corresponding profile iside the folder 🗀 Profiles)

Dependencies

sudo apt install ffmpeg git clex pv

I suggest to use the Clex File Manager for command line usage, but you can also use: "nnn" or some terminal such as: xfce4-terminal, gnome-terminal, konsole, tilix, qterminal, etc, etc

Installation

I suggest that you clone this project into some folder, and that you know that this program will always be cloned there:

git clone https://github.com/wachin/ffmpeg-screencast

next you must enter from a terminal into the cloned repository:

cd ffmpeg-screencast

write in the terminal and hit Enter:

clex

The first time you use clex you should configure it, hit Enter some times for that:

you hit enter again:

then appear:

CLEX configuration utility:

End of options mark '--' is supported
Pager program: less
Text editor: vi

=== BEGIN ==================
CMD_F3=less -- $f
CMD_F4=vi -- $f
CMD_F5=cp -ir -- $f $2
CMD_F6=mv -i -- $f $2
CMD_F7=mkdir -- 
CMD_F8=rm -- $f
CMD_F9=lpr -- $f
=== END ====================

Save this configuration (y/N) ? 

you need to give yes = y hit enter, and again hit enter, and it will be ready to use:

Screencast

Under clex first get on top of the script:

→ ffmpeg-yuv444p-losseless-mkv.sh

and hit Enter twice and it will start to record the screen in a box of 854x480 pixels:

to stop with:

⌨ Ctrl + C

To record another video repeat the process.

Join videos

To join the videos get on top of the script:

→ join-mkv.sh

and hit Enter twice, and wait a bit, the videos will be joined into the folder:

🗀 recorded-videos

if for some reason you need the initial videos they will be in the folder:

🗀 Old

To use it with a terminal

To use with some Linux terminal, just write the name of the script and execute with ENTER like:

Screencast

./ffmpeg-yuv444p-losseless-mkv.sh

You can help with tab to autocomplete commands

Join videos

./join-mkv.sh 

Other FFmpeg options I have made this program so that it records with the videos in the mkv format because it gave me the best results, but you can record with mp4 by copying some of the profiles that are in the folder:

🗀 Profiles

where there are also profiles to record in full screen, example:

and that is:

then run clex in a terminal in the main path and see:

hit Enter end the recorder are into the full screen

The beggining

First I started doing some tutorials on how to record the screen with ffmpeg from the terminal. In Spanish:
