Flash plugins execute programs written in the ActionScript programming
language. ActionScript can be decompiled but it often is obfuscated, i.e.,
the source code is inaccessible and the programs are proprietary, an
injustice. https://trisquel.info/en/wiki/play-videos-without-using-flash
See https://trisquel.info/en/wiki/play-videos-without-using-flash for
solutions on many (not all) websites. I happily use ViewTube and ViewTube+
and when it fails, I try UnPlug.
To add this PPA run this command in a terminal:
sudo add-apt-repository ppa:dnjl/multimedia
This PPA depends on another PPAs. To add them, also run:
sudo add-apt-repository ppa:dnjl/ppa
sudo add-apt-repository ppa:dnjl/kernel
sudo add-apt-repository ppa:kxstudio-team/ppa
sudo
Is my Trisquel system still free after installing this ppa?
This PPA only contains GNU packages. I believe it is safe to think that it
will always be so. You can relax. ;-)
