On fresh install to Parrot Home edition there is a little bug with ffmpeg, Vokoscreen doesn’t launch recording so i’m going to see on Vokoscreen web site and then give a solution:
The best way to change ffmpeg file is :
dowload your ffmpeg version (32 or 64)
open terminal and rename ffmpeg original file by :
sudo mv /usr/local/bin/ffmpeg /usr/local/bin/ffmpeg-original
After , place the new ffmpeg on it :
sudo cp ffmpeg /usr/local/bin/
That fix it.
